02:54 <set_> I got some tiny fans...

02:54 <set_> I cannot wait to test 'em. They came w/ glue. I am going to glue them to my BBB and let the good times roll!

02:55 <set_> Does the PCA9685 get hot, too hot, when over doing it a bit w/ some source?

02:56 <set_> Or better yet, is there a way to test the heat of the PCA9685 outside of thermal imagery?

02:58 <set_> And I got this ebay find thing. I think it is supposed to be handled by counters or digital readheads (if they work).

02:59 <set_> So, it is (encoder velocity (m/s) / resolution (um)) * 4 (safety factor)

03:00 <set_> So, from 5 to 20 MHz frequencies, I can find the answer of if they work...

03:01 <set_> The thing I found came w/ a stepper motor and some slides and the dang comparison voltage is 5v. Blah.

03:03 <set_> optical encoders! It is the old way of reading...

03:04 <set_> RS232!

03:07 <set_> What technology would I use that is located on my BBB to read an optical encoder?

03:08 <set_> i.e. not PRU.

03:11 <set_> Can the PWM peripherals onboard the BBB handle 20MHz?

03:19 <set_> So, eCAP and eQEP or either or?

03:23 <set_> Off to the forums!

03:31 <set_> It is kind of late on a Fri. Funday. I will retire for now!

03:52 <set_> Man...the retired life feels icky. Back to the BBB!

07:23 <arti4-92> Hello

07:23 <arti4-92> My name is Artur, a come frome Poland, im engeener of electronics that is eployed as electronic circuit construktor

07:24 <arti4-92> I have a question

07:24 <arti4-92> Due to my need of learning linux

07:24 <arti4-92> how to check with what version of uboot my patch file is compatabile?

07:25 <arti4-92> i want to compile newest version of uboot for beaglebone black, or toradex colibri pxa270 as a training

07:25 <arti4-92> have some old patch files that i found on a web

07:26 <arti4-92> but while compiling sources console returns me warnings about timer and ethernet

09:32 <AKN> Hi Everyone, Found the issue for ti-sgx-ddk-um issue i posted earlier meta-agl-bsp has bbappend file for ti-sgx-ddk-um

09:33 <AKN> After commenting out the bbappend file image is compiling without any issue.

09:37 <jsolano> Hi all, anybody had any luck compiling device tress (am335x-boneblack.dtb) on a recent linux kernel? I am using stable 6.1.

09:39 <jsolano> I keep getting errors due to include paths missing, basically include/dt-bindings is not available to the am33xx.dtsi. Some people had luck adding a sim link to include/dt-bindings at the right place within the dts area, but that does not work foe me

18:15 <med> hello can anyone explain this error for me please "Error: EINVAL: invalid argument, write"

20:00 <zmatt> jsolano: ehh, you mean you're trying to build the dtbs included within a kernel tree?

20:01 <zmatt> you definitely shouldn't need to symlink anything

20:02 <zmatt> within the kernel tree they're normally of course built as part of the overall kernel build process, but no doubt there's a make target to build just the dtbs or even just a single dtb

20:03 <zmatt> my first guess would just be "make ARCH=arm arch/arm/boot/dts/am335x-boneblack.dtb" in the root of the kernel tree

20:06 <zmatt> there's also the repo https://git.beagleboard.org/beagleboard/BeagleBoard-DeviceTrees/ that make it convenient to just rebuild device trees, but these are specifically the device trees of rcn's -bone and -ti series kernels

20:06 <zmatt> (which are the kernels typically used on beaglebones)

20:39 <jsolano> zmatt: you said it more clearly than I did, right, I am trying to build the dtbs included within the kernel tree. If I build a kernel with make zImage e.g., the dtbs do not get built. With older kernels some time ago I had to do make dtbs, but that does not work now with 6.1

20:41 <jsolano> ARCH is en env variable, I just do "make am335x-boneblack.dtb", and that fails with the missing path to dt-bindings/bus/ti-sysc.h

20:42 <zmatt> not sure what could be broken, rcn's build script for kernel 6.1 just seems to do make dtbs: https://github.com/RobertCNelson/bb-kernel/blob/am33x-v6.1/build_kernel.sh#L86-L89

20:42 <jsolano> this is a vanilla kernel, I am assuming the only reason why "make dtbs" does not work is a bug on this kernel. Some people have had to use these simlinks to fix it, which in my case does not work

20:43 <jsolano> thanks, I will try tomorrow with rcnÅ's script

22:13 <Guest2754> I am trying to build kernal for Beaglebone black after a long time and i realised that  now the /arch/arm folder donot have the  bb.org_defconfig  what is the config file that should be use now?
