Picochess v2.01+ switchable image

[Scally]

Hi all,

I have managed to create an image for Picochess v2.01 “plus” and upload it to my Dropbox account, how long this stays there is unknown as I’ve now used 115% of my free space. I haven’t the space or the internet speed to be able to upload 4 different images but perhaps someone else has.

It’s called PicoV201plus as it can be switched to either v0.9n or V2.01 as a DGT Pi image or a non DGT Pi image with 1 simple command after download, the default is Picochess v2.01 non DGT Pi.

Click below to download:

https://www.dropbox.com/s/8tf9h0xbmndmy3p/PicoV201plus.zip?dl=0

Click on “Or continue to website”, then click on “...” & “Direct download”

I don’t own an Apple Mac or iMac or any other Linux device besides my Raspberry Pi’s so these instructions are for Windows, I’m sure the method is similar though:

My image will fit on a 4gb micro SD Card or bigger, I’d suggest an 8gb card as some 4gb cards differ in size so the image may not fit.

I have used Win32DiskImager, dotNet Disk Imager and Etcher and find Etcher is the best tool for me to write images to micro sd cards.

If you use Win32DiskImager you will need to UnZip the downloaded file first, the other 2 Utilities can write the image from the Zipped file, Etcher also validates the copy.

Once the file has been copied to the micro SD Card it should work on a non DGT Pi, I have tried it on a Raspberry Pi 2, 3 & 3b+, my only DGT board is the Revelation II and my only clock is the DGT Pi, so other clocks and boards haven’t been tested.

If you want to use this on a DGT Pi or switch to Picochess v0.9n then you will need to be able to log onto the device and enter 1 simple command.

The quickest way without setting up Wi-Fi is to plug an Ethernet cable from your router to your RPi or DGT Pi and use a terminal. If you have a USB keyboard and a screen / TV then jump to “run 1 of 4 bash files”. Once the Ethernet cable is attached you can either log onto your router and find out the Raspberry Pi’s IP address or use an App similar to “Fing” which I use on my iPad. You will see raspberrypi.default with an IP address similar to 192.168.1.35
Then using another App like Termius or similar you can log into your Raspberry Pi. My settings are as the attachment, you can call it what you want but the IP address must match the Hostname.

The Username is pi
The Password is picochess

Once this is saved, you can click on your new Host and it will automatically log you on to your device:

Now you can run 1 of 4 bash files to chose your preference:

Type:

cd (Hit Enter)
ls (That’s small LS & hit enter)

See attachment ...

Chose your preference and type:

./your choice (Hit Enter)

i.e.

./to-v09n-nonpi
./to-v09n-pi
./to-v201-nonpi
./to-v201-pi

They are self explanatory, the device will reboot and boot up correctly into your choice of Picochess Version and Type.

Enjoy ....

Hi there Scally ,

Can you point out to me what is the difference between version 2.01, 1.0 and 0.9n of Picochess?

Thanks in advance!

Henri

 

[Scally]

Hi Henri,

v0.9n is Jürgen’s last official release, see here for details: https://picochess.com/picochess-v0-9n-revelation2-pi-mode/

v1.00 is Dirk’s personal release that he shared on the picochess forum: https://groups.google.com/forum/m/#!topic/picochess/sHBwvs0A9XM

v2.00 is Dirk & Wilhelm’s further enhancements, see: https://groups.google.com/forum/m/#!topic/picochess/ZecURopxPjk

v2.01 is Wilhelm’s volume enhancement which is detailed in the same v2.00 thread above.


So my image lets you switch between Jürgen’s latest level or Dirk’s.

Hello Scally and everyone.
Thank you very much for everything, I downloaded the image, recorded and placed in my Raspberry 3, but I can not get it to work, start but it is disconnected and the clock is blocked.
I do not know where the problem is.
I have used two different Raspberry and different cards and connection according to here:
https://picochess.com/howto-turn-a-dgt3000-into-a-dgtpi/

[Scally]

Hi Miguel,

You have turned your DGT 3000 into a DGT Pi therefore you need the DGT Pi image. The default image you have loaded is for a non DGT Pi.

Just follow my instructions in the first post in this thread to logon to your Pi and run my batch file

./to-v201-pi or ./to-v09n-pi .... depending what version you want.

Good luck

Al.

[Miguel Angel Munoz Ovelar]

Thank you. Problem solved, changed image to dgtpi and after waiting for two minutes with the raspberry connected to the electrical network reconnects the clock with the raspberry. Eternally grateful, Scally.

[Jogges]

Hi folks,
could someone tell me how to activate WLAN and the webserver in Picochess v2.01 non dgt ?
I would like to copy my pgn after a game and paste it into lichess, in order to analyze my game and learn from my mistakes.
Thanks!
Jogges

[Scally]

Hi Jogges,

Plug in an Ethernet cable and open a terminal (see instructions on my first post in this thread)

Then type:

sudo raspi-config
Chose option 2 Network Options
Chose N2 Wi-Fi

and enter your SSID and password

Once saved you can remove your Ethernet cable and reboot.

You can then simply type your IP address of your raspberry pi or type raspberrypi.local in a new webpage to bring up the webserver.
You could also enter your email details in the /opt/picochess/picochess.ini file and have your game emailed to you after every game. I can give more details if required.

Cheers,

Al.

[Jogges]

Hi Al,

Wifi works fine now! Webserver via IP-Adress also. Just raspeberrypi.local doesn't work.

But this is a minor problem!

Thanks alot!

Cheers,

Jogges

[Scally]

Hi Jogges,

I’m glad it works for you. In my haste to answer you I got the other option wrong.

Raspberry has been changed to picochess, so typing picochess.local will work, not raspberrypi.local (I just tried it)


Cheers,

Al.

[Jogges]

Hi Al,

thanks for your help!

I have a strange phenomena here:

http://raspberrypi.local works on ipad/Safari but not on WindowsPC/Firefox or Edge.

IP-Adress works everywhere.

http://picochess.local works nowhere.

Maybe put this to the X-files? :-)

Cheers,

Jogges

[Scally]

Hi Jogges,

I don’t type http etc, just picochess.local on a new webpage, that works for me, as does the IP address 192.168.1.35

But I’m glad yours works.

Cheers,

Al.

[Henri Spijkerman]

Tried to configurate the Picochess 2.01 non-pi and (almost) everything works great :)

Thanks again Scally for some awesome work!

Even got the emailservice working by changing picochess.ini. That is quite easy to do after logging in:

cd /opt/picochess

sudo nano picochess.ini

Change it and save, works like a charm.

Have to agree with Jogges though, the address http://picochess.local does not work on windows or android devices over here either.

There is always something to nag about! :)

Greetings,

Henri 

[Al]

Hi Henri,

I’m glad you’re up and running.

As I said earlier, I don’t type http etc, just picochess.local on a new webpage, that works for me, as does the IP address, in my case that’s 192.168.1.35

Cheers,

Al.

[Henri Spijkerman]

Sorry Al, not over here!

Greetings,

Henri

[Henri Spijkerman]

Ok, found it. The hostname is still raspberrypi, so raspberrypi.local works, not picochess.local!

Changing the hostname will do the trick:

https://www.howtogeek.com/167195/how-to-change-your-raspberry-pi-or-other-linux-devices-hostname/

Greetings,

Henri

[Al]

Hi Henri,

In my thread I suggested raspberrypi.local but in my image I changed the host to picochess hence picochess.local

I’m happy it’s working for you

Al.

[Kram Ping]

Good day,

Im really looking forward to this, I worked on Non-DGT pi, 

Does v.2.01 works on Reed switch Arduino nano board?

Hi there Scally,

I am trying to install some additional stuff on the picochess sd-card. My sd-card is 16gb, but it behaves as a 4gb card, so I'm lacking diskspace. It seems I need to resize a partition, but as a Windows man I'm really getting into deep waters there. Do you know a noob solution? Maybe a 8gb image?

Thanks in advance for any help,

Henri

[Jogges]

Hi Henri,
type sudo raspi-config in terminal window. There is an option to expand the storage volume to the size of the SD-Card.
Cheers,
Jogges

Hello Scally. You can not switch this download version, because after entering pico the password (picochess) can not be entered. No character can be entered via the keyboard!

[Scally]

Hi Peter,

I’m not sure what you mean, it works for me and others?

When you enter the User Id and password in the Edit Host, you then save the host, then click on the host name to logon. Assuming your IP address and other parameters are correct it will automatically log you onto your RPi.

Hello. Have Picochess v201 + with stockfish 10 of you. Everything great! Question: How many cores (threads) is running? Stockfish 10. Greeting Esser

[Michael Byrne]

Normally it’s one unless you change it. The max would be 4.   At 4 threads  , the Pi will overheat and then the cpu would be throttled.  Even with using just one thread , SF 10 plays at better than World Champion strength because it would throttle at 4 threads , the Elo gain of 100 Elo which is what you would expect going from 1 thread to 4 threads , is probably only 50 Elo.  The more threads you use , the faster it would be throttled , the quicker the slowdown.

Hi Peter,

I’m away for 2 weeks.

If you look in /opt/picochess/engines/armv7l/a-stockf.uci it will tell you. If it’s the default a-stock.uci then there will be no ‘Threads = x’ in this file, so it will use 1 Thread, if it’s a copy of mine, it should have ‘Threads = 3’ as the default with the top 2 levels using 4 Threads. As Michael said, you will need a good fan at 4 Threads, you can always change these values yourself.

Al.

[Henri Spijkerman]

Hi there Al,

Just a question: Why are there different versions of Rodent III on the 2.01-non-pi version of Picochess? In the arm6 section there is version 0.228, in arm7 0.233. There are also differences in personalities. Is there a reason for that or is it 'just' a minor mistake?

Hope you are enjoying your cruise  :)

Henri

[Michael Byrne]

Arm 6 is no longer being updated, .233 is latest. Most people would use arm7.

[De Kift]

Hi Al,

Thanks for this image! I just installed it and my initial impression is that it's working fine.

However: I'm running 2.01 on a DGT Pi and the boot time is now about 80 seconds compared to about 10 seconds for the standard 0.9n version that I was using.

Can you confirm if this is normal or do you think there's something wrong in my configuration?

Cheers,

Marcel

.....................

[De Kift]

Hi Al,

I changed the hostname to "pi" (it was "raspberrypi" in your image; I think that's mentioned in this thread) and now the booting process is less than 10 seconds like it used to be.

No need to reply but maybe this should be noted somewhere? It's quite confusing. I also couldn't log in with Putty (not with "raspberrypi" and not with "pi"), now I can (with "pi").

Cheers,

Marcel

[De Kift]

Sorry Al but now suddenly the  boot time is at 80 seconds again (not sure what happened though).

Do you have any idea what's the cause of this?

Cheers,

Marcel

[Scally]

Hi Marcel,

By ‘boot’ are you referring to the connection to the board?

My board and Picochess are still packed away from my cruise and her living room remake including new furniture, I’m hoping to be up and running by the end of the weekend.

I will time the Bluetooth connection to my Revelation II from my DGT Pi with the a Raspberry Pi 3b+ inside then, I’m sure it’s around 10 seconds as you said.

My software is always updated so in the meantime you can try updating your software:

sudo apt-get update -y
sudo apt-get upgrade -y


Cheers,

Al.

[De Kift]

Thanks Al,

It took 80 seconds before the DGT was ready with the booting process (my raspbian was already up to date BTW).

Anyway: in the meantime I have made a stand alone version of v2.0 from your image.

Now it works fine and boots really fast again. Sorry for bothering you. Have a nice weekend.

Cheers,

Marcel

[Peter Eßer]

Hello Scally. Your Picochess 2.01 runs without error. Thank you again! Can you tell me if there's a new vesion? (2.02 or otherwise). Greetings Esser

[Torben Østergreen-Johansen]

Thanks a lot for this great image, Al (and other generous developers) :-)

Unfortunately I have now been able to play and test it nearly as much as I would like, since I seem to be having a lot of bluetooth connectivity issues.

I recently upgraded from Pi2 (with a bluetooth dongle) to Pi3+, but I am having the same problems with both. Sometimes picochess connects to bluetooth and everything is fine, but mostly bluetooth does not connect and I am unable to play. Is this a known problem? I did not change anything in the settings or files, except I did in fact connect to wifi.

I have unsuccessfully tried to solve the issues by running bluetoothctl. My DGT e-board is easily found and apparently also connected to when I give the commmand "scan on" (at the command prompt it is written in blue: [DGT_BT_21722] and the little lamp on my DGT board goes from blinking to solid green), but despite this picochess does not start and my DGT clock also does not verify that picochess is started. I am a noob at this, so maybe I am missing some important options in bluetoothctl?

Should I update anything in this image uploaded by Al?

Thanks!

Regards
Torben

[Torben Østergreen-Johansen]

UPDATE:

Having fiddled around with the connectivity issues all day long, I finally found the source of all problems: A broken switch (for the cable) INSIDE the DGT clock was causing the connectivity to be a question of hit or miss. Most of the time the connection was broken, but pushing the cable or the clock would sometimes establish connection. Actually this was easy to see if I had just taken a closer look on the DGT clock: When connection between the clock and the DGT board is established, two small arrows (pointing in opposite direction) can be seen at the top of the display. When no connection is established, these two arrows will not appear. As simple as that.

So actually this was not a bluetooth problem at all.

I just ordered a new DGT 3000 Limited Edition clock, which has a nice bonus: It has a wooden look, which will fit my DGT board perfectly.

All's well that ends well :-)

Regards
Torben

[Scally]

(Attempt #4 photos were upside down)

Hi Torben,

I’m glad you sorted out your problem, most connectivity problems seem to be with either the batteries or the connecting cable.

The Limited Edition DGT 3000 is really nice, I’ve had one since it was released, I swapped the base with a DGT Pi to give me that ‘Wooden look’ that matches my Revelation II.

Cheers,

Al.

[Torben Østergreen-Johansen]

Hi Al

Thanks, it was nice to find the source of all my connectivity issues. A simple problem with a simple solution. I like that :-D

It is indeed a very nice setup you have, including the Rolls Royce of all chess computers. A fine touch to switch the top of the DGT-pi with the wooden look of the DGT3000 clock.

I am quite nostalgic about old chess computers, fondly remembering my Boris Diplomat (a really weak computer), my Scisys (still relatively weak), my Novag Super Constellation (my all time favorite by far, though not of Master strength) and my Mephisto Exclusive MMIV (Master strength). Quite a lot of these and similar old engines have been brought back to us through MESS. I wonder if any of these engines are working in picochess. I am the happy owner of the chess computer Gavon (Novag spelled backwards!), which actually have quite a few of these engines available and is able to run these on a Raspberry Pi. However picochess has a far more intuitive interface.

Do you have any thoughts about that?

Cheers

Torben

[Torben Østergreen-Johansen]

Hi again, Al

I may have posed my question in an unclear way, sorry about that. I was not asking about Gavon versus picochess, I just wondered - knowing that you are very knowledable about chess engines and picochess - if you know about old engines being able to run in picochess.

Regards
Torben

[Scally]

Hi Torben,

I have Gavon too, but I knew what you meant.

I’ll stick with my answer, I couldn’t possibly comment on older engines and Picochess .... yet 😉

Your response is quite okay of course, except now you really got me interested about what might be coming up 🤩

[Alexander Vogelmann]

Hi @ all,

if choose th V201 for mi picochess, I can see the stockfish 8 in my option. But can you crate a image with all new engine and V201 or 91n for DGT PI ????

Or can you give me a link with direction how i can implement the stockfish 10 and Leela chess zero engine???

With is the right folder if i choose the V201 on this image????

Thanks for your support.

[Alexander Vogelmann]

OK Lella chess zero is done I need only stockfish 10 instruction.

[Scally]

Hi Alexander,

It depends wether you want the official Stockfish10 released some time ago, or today’s latest Dev version, both are attached.

Whichever version you choose will need to renamed to a-stockf and be copied to the 

/opt/picochess/engines/armv7l  folder.

Then execute permissions need to be set:

cd /opt/picochess/engines/armv7l

sudo chmod a+x a-stockf

Then alter engines.ini to reflect the engine name selected via the clock:

sudo nano engines.ini

scroll down to here:

name = Stockfish 081017 (or similar)

small = stockf

medium = Stockf8

large = Stockfish8

alter the 4 lines to this:

name = Stockfish 10

small = Stf 10          (max 6 characters)

medium = Stocf 10   (max 8 characters)

large = Stockfish10   (max 11 characters)

save and reboot, you can then select Stockfish 10 on your clock.

Cheers,

Al.

[Alexander Vogelmann]

Thanks a lot. Everything works.

[Torben Østergreen-Johansen]

UPDATE NO. 2

The DGT 3000 Limited edition chess clock has now arrived, and I am now able to connect my DGT e-board with the chess clock. So far so good.

Unfortunately the bluetooth connection between Picochess and my DGT board is not working properly. I am able to pair them, but Picochess will not automatically connect after I have restarted. Using the bluetoothctl command I am able to connect manually, but this gets really frustrating.

Any ideas will be greatly appreciated.

Regards

Torben

[Scally]

Hi Torben,

Assuming the Bluetoothctl command is to to remove the BT address of your board, then you could try this which worked for me on Buster, reported in my “Raspbian Buster - Good News” thread:

sudo crontab -e

Add this line to the bottom and save:

@reboot /bin/echo -e 'remove xx:xx:xx:xx:xx \nquit' | bluetoothctl

Where xx:xx:xx:xx:xx:xx is your board’s BT address


I’m away now until the 20th of November ....

Cheers,

Al.

[Torben Østergreen-Johansen]

Thanks for your suggestion, Al.

Unfortunately it did not solve my problem. Everytime I switch my Pi on/off the automatic bluetooth connection fails.

I wonder if other users of Picochess are having similar problems? My Picochess is running on a Pi 3b+

Regards
Torben

[Torben Østergreen-Johansen]

UPDATE NO. 3

All bluetooth connection problems finally solved.

Having observed a very unstable bluetooth connection (sometimes it autoconnected, sometimes not), I began to suspect the on board bluetooth chip on my Pi 3b+

I put an ordinary bluetooth dongle in my Pi - and suddenly everything worked like a charm! I have now both rebooted and switched my Pi on/off several times just to test the stability, and everytime Picochess has autoconnected to my DGT board in a few seconds. I have also played a few games with no problems at all :-)

I have never heard of a weak bluetooth chip on the Pi, but there is a first time for everything.

Now I just wish I knew how to install some of the old chess engines from MESS-chess in Picochess...

Regards
Torben

[Peter Eßer]

Hallo Scally. The program LC0 Nibbler 1.1.1 is very good. Is it theoretically possible to install a driver for the DGT board and the DGT PI? Greetings Esser

[Scally]

Hi Peter,

Nibbler looks like a great GUI for Lc0 but I’ve never used it, nowadays I’m mostly Linux based, most of my Linux systems are the Lite build without graphics.
I’d imagine they could add DGT board compatibility but Picochess and Nibbler are totally different in the way they work.

I do have Lc0 on Picochess as I’ve said before, it runs a lot slower being CPU based rather than the GPU monster it’s become, but it’s still a nice Engine on Picochess.


Cheers,

Hallo Scally. Is it likely that Stockfish 11 will be available for DGT PI soon? Greetings Peter

[Scally]

Hi Peter,

Certainly, please find attached the 2 files you need to replace your a-stockf & a-stockf.uci.

Copy these to  /opt/picochess/engines/armv7l  and give a-stockf permissions via  chmod a+x a-stockf

Then you just need to edit file engines.ini  and scroll down the top engine. [a-stockf]  & change the references from Stockfish10 to Stockfish11 like this:

name = Stockfish 11

small = Stf 11

medium = Stocf 11

large = Stockfish11

Cheers,

Al.

[Peter Esser]

Thanks Scally. But as I said before, this method is a bit too difficult for me. I better wait. At some point there will be a finished download version for DGT PI with Stockfish 11.
Thanks anyway for your (as always) quick response. Greetings PeterOn Fri, 14 Feb 2020 02:12:42 -0800 (PST)

Hi Scally,

I did it before but forget how.

I got  The DGT pi running on your 201 version, to make there a image from to set it for download for Peter?

Kind regards,

Hallo Scally. Do you have a ready-made image for Rasberry non PI with Stockfish 10 which I can write on an SD card without having to change the system? Greetings Peter

[Scally]

Hi Henry,

The first post in this thread has a link to an image where the default is Picochess v2.01 and non DGT Pi, so should work for you without change.

It should have Stockfish 10 as that was released December 2018 and this upload was Feb 2019

Please try and let me know.

Al.

Oops sorry Peter.

Henry should read Peter ....

Hi Peter,

Here my image for GDGTpi with stockfish 11

http://gofile.me/3hYSk/nzIGy5niH

It is public so you can pass it on.

Hi Peter,

I don't run Linux, so i cant shrink the image, then it is the size of the SD card and that was 16 , but it works if you put it on a 4 or 8 SD card with Win23Disklmager. I put a other in already is:7,39.

Also got a Paspberry version:

Same 7,39 size but 4 will do!

Hi there Peter,

It is a fresh image so the wireless is not set yet. Hence a wireless keyboard or any other wireless device is not detected. Instead use an ethernet-cable to connect the pi to your network.

After that, use a program like 'Advanced IP Scanner' or 'Angry IP Scanner' to detect what the IP of your pi is.

If you know that, use a program like 'Putty' to connect to the pi. User: pi  / Password: picochess

Once connected, start the picochess option you want and reboot. Picochess should work flawlessly.

To get most out of Picochess (f.i. moves by mail) you have to adjust the picochess.ini file. A bit of linux knowledge is essential for that, but Google is your friend and you get a lot in return for the effort! But first try the above to get things started.

Henri, wireless keyboards don’t use the wireless network.😉

Peter, ensure the USB dongle is inserted. I assume you are using a monitor connected to the RPi? You should arrive at the login prompt after applying power.

[RandyR]

Peter,

Here is an updated image with Stockfish 11. I tested it and it works on my DGT Pi. It should work on the non-DGT Pi if I edited the folders correctly, but I could not test it. You should be able to attach a monitor and keyboard to run the script after logging in.

Hi Peter,

Did your download my version non DGTpi but  the Raspberry Version i put online?

Always first with NetCable like Henri told you.

You must put up a network connection.

Or did you try to use the SD wth the DGTPi image on a Raspberr?

That wont work, download my other version.

Here from you.

Kind regards,

Tom

Hello Scally. Can I install picochess v201 on a Rasberry 4b (without network audio, Vidio)?

[Scally]

Hi Peter,

Yes, any version of Picochess works on Raspbian Buster which the RPi 4 needs.

If you’ve already converted your Stretch system to Buster then the micro sd card is interchangeable between RPi versions.

I currently have a DGT Pi with a RPi 3b+ inside running Raspbian Stretch. I have some converted micro sd cards from Stretch to Buster as described in earlier threads. I’m currently compiling my Picochess engines on Stretch, which run on Buster, but it won’t be long before I convert to Buster only.

Buster runs fine on my RPi 3b+ within my DGT Pi but on the RPi 4 (which doesn’t fit the DGT Pi) all runs well except the Bluetooth connectivity. The voice issues have been resolved and the Webserver works. Bluetooth connectivity only works with my code change/fix/hack as described before.

I have 2 RPi 4’s, 1 is now reserved for compiling engines plus a new project to be announced soon, this boots to a 256gb ssd drive and is overclocked to 2 GHz. The other has an ice tower cooler fitted and will be my main system very soon, replacing my DGT Pi, as my DGT board is the Revelation II which can now emulate the DGT Pi functionality.

I will post some pictures later this week and maybe a video or 2.


Cheers,

Al.

Hi Al

That sounds very interesting. Your efforts are greatly appreciated!

Hello Scally. Bought Rasberry 4B, Raspian Buster installed, SD card with Picochess V201 Stockfish 11 inserted. Red lamp lights constantly, green lamp constantly 4 times in quick succession Picochess does not work !? Greetings Peter

[Scally]

Hi Peter,

That’s not much info to go on ....

Silly question but you say you installed Buster then inserted another micro sd card, does that have Buster on it?

The RPi 4 can only run on Raspbian Buster, older RPi models can run on Jessie, Stretch & Buster.

Although my main DGT Pi is running on Stretch, my micro sd card with Buster runs on all my RPi’s as per my video. If you are inserting your old micro sd card (with Stretch) into your new RPi 4 then it will not work. The operating system is contained on the micro sd card not the RPi.

If this is not what you’ve done then please explain what does happen, i.e do you see DGT Pi on your clock etc?

Al.

[Peter Esser]

Hello Al. Installed the operating system Raspian Buster with Noobs on Rasberry 4B. Then I removed the SD card with the operating system just installed. I then inserted the SD card with Picochess v201 Stockfish 11 into the Rasberry 4B. After the Rasberry 4B was supplied with power, the red lamp was always on and the green lamp was always 4 times in a row. But Picochess was not started from the SD card. There is only picochess v201 Stockfish 11 on the SD card. No buster. Raspian Buster is an operating system on Rasberry 4B. ?? How do I get Raspian Buster on the SD card with picochess v201 Stockfish 11?Greetings Peter

Hi Peter,

Hmm, as I thought you inserted your old micro sd card which has Raspbian Stretch on it, this won’t work on the RPi 4.

Ok, you have 3 options:

1) With your new micro sd card with Buster in your RPi 4, build Picochess from scratch as Randy has just done.
2) Backup your old micro sd card and convert from Stretch to Buster on your old RPi 3 or whatever you have, it will then work on old and new RPi’s.
3) Wait for someone to supply an image of Buster with Picochess already installed, this will then work on all RPi’s, in the mean time continue to use your old RPi.

Hi Al,

Can you please help me with an error code I'm getting on the bootup screen.

I have a pi 4 with the dgt 3000 ver. 2.02 B150409. I've tested the wiring with a multi-meter for continuity.

I've mounted the pi buster with picochess v2.01 included.

But on the bootup screen i get an error - (FAILED) Failed to start DGT PI Hello 

See 'systemctl status dgtpi.service' for details. (see picuture, bootup fail)

So I ran the systemctl code in terminal.

dgtpi.service - loaded failed failed (see picture, systemctl)

If you or anyone can please help.

Thanks

Liam 

[Scally]

Hi Liam,

The RPi 4b does not work in the DGT Pi, I’m assuming you have the DGT 3000 with the wiring conversion to a DGT Pi, or have I misunderstood you?
Assuming you are using this conversion kit then ....

I showed a video a couple of weeks ago showing Raspbian Buster working on my DGT Pi that’s has a RPI 3b+ inside, then switching the micro sd card to RPI 4 changing the picochess.ini file to reflect DGT Pi = False and booting it up and connecting it to my Revelation II board via Bluetooth O.K. This may have confused others into thinking it was working in a DGT Pi, but it shows clearly it was a stand alone RPi 4 with the extravagant Ice Cooling Tower: https://www.dropbox.com/s/lju7pz6yo6he2um/Video%2026-02-2020%2C%2011%2030%2033.mov?dl=0

The RPI 4 doesn’t fit the DGT Pi because the connectors are either different sizes or in different places, secondly I remembered Lucas of DGT saying something in another thread, so looked it up.

In this thread:

https://groups.google.com/forum/m/#!topic/picochess/4dyvi9di6Nc

Lucas said:

“If you would want to replace the pi 3 with a pi 4 in your DGT Pi I see another problem. There used to be an I2C slave device on GPIO 18 and 19 (alt 3). We need this for direct communication to the DGT3000. Unfortunately it is no longer there. In fact I cannot find any I2C slave device on the new Pi 4”

He followed this up the following day with this:

“Good news,

According to: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711/rpi_DATA_2711_1p0_preliminary.pdf page 10 there is no longer an I2C slave device on the pi 4. However there are 4 unused pin-function combinations. According to https://github.com/RPi-Distro/raspi-gpio/blob/master/raspi-gpio.c these pins do contain the I2C slave device! So with some changes in software and moving the wires to different pins it should be possible to us a pi 4 in a DGT Pi. Some mechanical modification to fit the new connector locations would be necessary.

I don't know yet about the Bluetooth and voice, but this should also be fixable”

Obviously since then, Voice has been fixed and we get around the Bluetooth problems with my fix, however nothing more has been heard on the software or hardware changes that would be necessary.

If you’ve not done this conversion then what exactly is you connection to and via what?
i.e. RPi 4 connected to a DGT board via cable or Bluetooth or Revelation II, with or without the DGT Pi conversion kit.


Thanks,

Al.

[liam luty]

Hi Al,

Thanks for the reply, but I don't have a DGTPi, I have a DGT 3000 with a Pi 4 4gb, I'm trying to connect in up to a DGT smart board with a USB, no bluetooth on it, I'm sure you connect the DGT board via the USB on the Pi 4, as I've seen old videos on Youtube that used the phone jack to Pi.

Have you seen the error that I was getting in the last post or do you know of a fix.

I've done this https://picochess.com/howto-turn-a-dgt3000-into-a-dgtpi/

Thanks again Al

Liam

[Scally]

Hi Liam,

As I thought, you’re trying to turn your DGT 3000 into a DGT Pi, this will work with a RPI 3b+ downwards but not on the RPI 4 as per my previous post.

Yes you can connect a stand-alone RPi 4 via USB or Bluetooth to a DGT board but not with the DGT Pi conversion kit, as far as I’m aware.

I’m open to be corrected, but then again I’ve never used a direct connection only Bluetooth and that’s to my DGT Revelation II.

I hope somebody else can help you, but sorry, I can’t.


Al.
