Compilation fails with dtsi file not found.

[DeKay]

Hi

I am trying to compile the 4.1 kernel as per this eewiki link. I started on a fresh The kernel compiles but the compilation script bombs when it gets to the dtbs stuff because it can't find a file.  Help appreciated.

Thanks for looking at this so quickly.  Unfortunately I've been away and am only getting back to this now.

I seem to have the same problem.  This is on a BBB for which I am trying to compile a 4.1 kernel via "git checkout origin/am33x-v4.1 -b tmp".  I kicked things off with a ./build_kernel.sh expecting that that would have pulled in your fix. The file "am335x-boneblack-1ghz.dtsi" itself appears to be missing still.  Is there anything else I need to do to get this file pulled in?

[dk@laptop bb-kernel]$ find . -name am335x-boneblack-1ghz.dtsi
[dk@laptop bb-kernel]$

By the way, I did notice the warning below early on (see bold text). Perhaps related?

You need to update the repo...

git checkout master -f
git branch -D tmp
git pull
git checkout origin/am33x-v4.1 b tmp
./build_kernel.sh

[DeKay]

I needed to, indeed!  Everything seems to have compiled this time around.  Thank you very much.

Hi Guys,

unfortunately i am also not able to find this file am335x-boneblack-1ghz.dtsi

could you provide me with the exact location.

Thank you
Attila

If you need that file to override your clock frequency, then your git
checkout is too old..

as it's now taken care of by the driver...

[Moon Walker]

Hi Robert,

thank you for your prompt reply.
I am in your dtb-rebuilder repo and trying to use the 1wire driver since monday unsuccessfully.
I am so disappointed now since with arduino it succed in an hour...

Thx

So use your Arduino . . . unless you have something actually constructive to say.

I asked a question and pointed my frustration wit linux! You are the one not constructive!!
But do not worry man! I went to the previous debian image and made it in half an hour.
Thank you for your nothing.

So, you asked a question, you got an answer, after which you felt compelled to compare a very capable embedded linux system, with a bare metal embedded system for 5 year olds. Did you expect a pat on the back ?

You're right. What I said was not constructive. I return comments in kind. Maybe next time you'll actually come back with "Thank you Robert !" Instead of being a jerk.

Me ? I don't have to worry about being a Jerk, I can actually figure things out on my own - Given enough time.

[moonwalker]

You frustrated faggot!

This was my first sentence in my answer:

"Hi Robert,
thank you for your prompt reply."

You are the one that makes BBB community worst! It is no wonder that this platform is so weak...

I do not think it is a good promotion to BBB. I will swithch to other plattform asap. And i will not recommentd

this community to nobody!

Hello Nelson,

I am currently trying to get the one wire working with a beaglebone.  I have done various paths but can't seem to get any to work.  Would you be able to direct me to a webpage that works for the beaglebone using the lastest kernel and a ds18B20?

Thanks,

Cory

Download the latest iot image:

http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Jessie_Snapshot_iot

disable cape_unversal=enable (open /boot/uEnv.txt)

reboot

then follow:

https://github.com/beagleboard/bb.org-overlays/blob/master/examples/BB-W1-P9.12/example.sh

(hint, p9.12 is the gpio used in that example)

[cory cauvier]

just got the newest version now I'm looking to do your next step.  I don't follow your disable cape_unversal=enable (open /boot/uEnv.txt) Are you asking me to remove the # from this?  I also don't have disable cape_unversal=enable

tHanks,

Cory

[William Hermans]

cmdline=coherent_pool=1M quiet cape_universal=enable

Remove, the bolded text. Or better yet, copy that line. Remove that text, then comment out the original line.

One more thing. make sure all other cmdline= lines are also commented out. As the last line will likely override previous lines.

hello William,

Robert said to follow the steps on the like he sent me for github.  It sends me to his code do I don't quite follow?  Do I go back to the main page on overlays and do all the steps?  

Thanks,

Cory

Did you disable cape_universal=enable in /boot/uEnv.txt and reboot?

Then just:

wget https://raw.githubusercontent.com/beagleboard/bb.org-overlays/master/examples/BB-W1-P9.12/example.sh

sudo /bin/bash ./example.sh

* assuming you plug your device in P9.12

[cory cauvier]

thanks robert.  I did what william said.  I removed the bold text in his reply.  I did the wget as well as the bin bash.  What is suppose to happen after I run bin/bash?  

thanks,

Cory

[William Hermans]

It'll load the w1( one wire ) driver module if not already loaded, then it'll get the temperature from the device every 5 seconds. It'll also load the BB-W1-P9.12 device tree file. I'd assume you'd need to edit this file, or change the overlay file to be loaded if you need to use a different pin.

if [ ! -f /sys/bus/w1/devices/28-*/w1_slave ] ; then
	modprobe w1-gpio
	echo 'BB-W1-P9.12' > /sys/devices/platform/bone_capemgr/slots
	sleep 1
fi

That pretty much mean if file /sys/bus/w1/devices/28-*/w1_slave exists -> modprobe w1-gpio -> load the BB-W1-P9.12 file into capemanager 
then of course -> sleep for 1 second.

If you need a different pin for one wire, then you'll have use another device tree file in place of BB-W1-P9.12

You have the hardware..

dmesg

and look under:

/sys/bus/w1/devices/

You'll figure it out..

If file DOESNT exist. Sorry I missed the exclamation mark there initially. which is boolean NOT.

Why did you load it more then once?

[cory cauvier]

I couldn't find your example file this morning.  Said it didn't exsist.  I was troubleshooting and decided I should start from scratch.  Didn't realize it was loading it into the cape overlay each time

[cory cauvier]

When it says not registered does that mean the program is running but can find any onewire devices?

thanks,

Cory

[cory cauvier]

got it working!!! ow man I jumped out of my chair and gave a shout!  thanks for the help!
