Software installation procedure?

[wafi wafi]

Hi Johan and fellow OMs,

Just finished soldering the beta4 board(cut trace under C256), and done a detail visual inspection on each soldering pad. Every 1117 has correct voltage output. And I dont have an oscillator for further checking.

However, when I start the pihpsdr, it shows no device found.  I started over the whole procedure again and still reached the same result.

Here's my procedure, please advice where went wrong. Thanks OMs.

1. Install the Pi OS from Pi Imager(v1.6）
2. Set the configuration as mentioned in wiki

3. wget pihpsdr and run pihpsdr.sh  twice(no error alert)

4. wget stable version of radioberry sw and run radioberry_install.sh

(no matter whether the beta4 board plugged onto RPi4 or not, during the installation it shows a lot of error alert and the most important one is: fatal error: "module radioberry" not found.)

 

Much appreciate again for any advice that can help me to get thru this. 

cheers 73

Hi BH4DTT

Missing your name.

i think you need to install the dev release.

The stable is not that stable with the latest rpi linux release... hi

Please read the check section at the wiki

https://github.com/pa3gsb/Radioberry-2.x/wiki/Radioberry---Configurations

The device driver is not installed... i think the problem will be visible in the terminal window when installing.

Please  if this direction is not working ;provide the log of the installation progress.

Hope this helps.

Thank you Johan,

My name is Jason. 

Just followed your advice restarted from zero. Although there're still the same error messages, at least now it can detect the device when beta4 board is plugged.

Also read and followed the check section and found one thing different.

Here are the screenshot of log. The last pic is the window when running pihpsdr, seems something wrong .

Thanks for the screen prints.

Now you have the device driver installed! Nice.

The version of the gateware differs in your report.

This version must be set always right.... what is happening when you are rebooting and restart pihpsdr... does pihpsdr show the gateware version?

sudo systemctl stop radioberry

sudo modprobe -r radioberry

sudo modprobe radioberry

sudo systemctl start radioberry

start pihpsdr   .... gateware version must be there.

Having this set properly means that your clock from AD9866 is there!

This clock must be configured via the SPI (from fpga to ad9866).... check if this is executed?

Can you measure the frequency of pin 53 of the FPGA?

Hello Jason,

I built 2 boards and had the same problem with both, as you.

The ground connection between fpga and ad9866 was the problem.

I had to re-solder this several times.

i suspect mechanical tension. 

Even if the circuit board worked at first, it didn't work a day later and I had no gateway display (Gateway = 0-0)

Hi Manfred, 

At least your device can be found right?  I'm still looking for problems. I used hotplate reflow to sold the board, finished at the first time and checked many times.

Hello Johan, 

Thanks for the advice again.

I don't have an oscillator so can't measure the freq of pin 53 of the FPGA, but the voltage of that pin is around 1.67V, as well as pin69 and pin19 of AD9866. Don't know if it's correct.

And followed those commands in sequence where the screenshots are  as following:

At first, I input $sudo radioberry right after started pihpsdr as the screenshot shows above, however, it returned Failed to open file

After I clicked the device on lo(click START button), and input the command again it shows the status:

but still no spectrum there.....

Then I tried all over again. And the gateway version changed and screen format too.

How about the status of tag "CONF_DONE" of R301 and Pin14 of the FPGA? What status or voltage should be before and after configuration?

Hello Jason,

Thanks for all the pictures.

The radioberry uses the GPIO pins of the RPI.  You have setup pihpsdr using GPIO.... 

please follow the wiki : https://github.com/pa3gsb/Radioberry-2.x/wiki/piHPSDR-running-CW-mode

Furthermore 

You are not able to measure the clock.... but indeed you are able to check the clock by turning on TX.

Your timing is not ok; tx write execute must be fit in around 1000 msec.

sudo systemctl stop radioberry

sudo modprobe -r radioberry

sudo modprobe radioberry

Than in a terminal execute radioberry  ( if you use sudo systemctl start radioberry  ; a radioberry is starting claiming the dev and starting radioberry; you get the message resource busy)

In your pictures this behaviour is as expected and working fine.

Your problem is in the software setup of pihpsdr and maybe a building error....

please first get your pihpsdr setup right.

than check gateware version 

than check the TX timing

Please let us know how it behaves now?

Hello Johan,

Just followed the setup and should be right.

And the gateware version now all consisted to 7.3

However, the TX timing is still over 1000ms

And the screen show temp over 80c

and sometimes shows sequence error

sorry to troubling you so many times.

The AD9866 seems not to get initialized. This initialisation is done via SPI bus, from FPGA to AD9866.

Please check your soldering.

The TX timing indicates the succes or failure of the initialisation.

Hello Jason,

the voltage 1.69V at pin 19 of the AD9866 is OK

I also had the strange behavior as you describe it

with the many attempts to start the program.

There were no further errors with my two boards!

The causes were exclusively the two ground connections !!

Did you re-solder them again ???

Hi Manfred,

Thanks for your sharing.

I've re-soldered them and check carefully again, every pin connection is good. 

Please advice me where exactly the ground you mention. 

Thanks a lot.

Hi Johan,

I've checked and re-soldered those connection but still got the same result.

Maybe I should change another AD9866? >__<

Hi Jason,

I don't mean the pins, i mean the back (ground) of the Ics.

This must be 100 percent and perfectly connected to the ground on the circuit board. (through the 5 mm hole in the pcb)

If that is not the case then there are these strange effects

as you described.

[wafi wafi]

Hello Manfred, 

For those two holes on the back, yes, I did make it 100% connected to the ground. But still the strange effects exists. 

Anyway, I gonna desolder the AD9866 and change another one.

Thanks a lot.

Hello Jason,

JL1VNQ's blog shows a case where the AD9866 was replaced and it worked fine.

I hope it will be useful for you.

Hi Yado-san,

Thanks for the reference.

I'm waiting for new AD9866 to come. 

Meanwhile, do you know what were the commands JL1VNQ used to get the rx timing? 

cheers

Hi  Jason, 

That's the HermesLite Emulator that was used in Radioberry 2.0 Bata2.

 And ran the launch.sh script to execute firmwareloader and piHPSD.
- https://github.com/pa3gsb/Radioberry-2.x/tree/master/SBC/rpi-3/software/

-               hermes-emulator/* ,  launchradioberry/launch.sh

In the latest version, spi-executed time display when TX only. (push MOX)

However, I think If the display shows about 1000ms in TX, working correctly.
