00:00 <set_> Oh!

00:01 <set_> I know no one really cares but I figured out how, I can almost replicate it, to use WSL2 w/ ext4 on Win 11.

00:02 <set_> I saw someone in the forums asking about wsl2 Debian and porting to/from it.

00:02 <set_> I could not find it again. It is a hidden message or something now.

20:37 <Guest44> I'm trying to use the Adafruit_BBIO.ADC module on my BBB which is running a Buildroot image.  But when I run ADC.setup() it fails with this error: https://pastebin.com/0px1vMVU

20:38 <Guest44> I don't have any capes installed.  Any suggestions as to how to fix it?

20:43 <Guest44> It's suggesting there might be a device tree conflict so I decompiled my am335x-boneblack.dtb and the one from Debian (for BBB) and they're nearly identical except for some values in the pinmux@800 section (at line 800 coincidently).

20:46 <zmatt> Guest44: the adafruit libs are generally terrible

20:46 <zmatt> in this case it's also almost certainly making assumptions that do not hold in your buildroot environment

20:47 <Guest44> zmatt, I suppose.  The GPIO portion of it works fine on my BR image.

20:47 <Guest44> But those are just digital.

20:47 <zmatt> just use the iio python library

20:48 <Guest44> Hmm, I'm not familiar with that.  (Goes to look)

20:49 <zmatt> example: https://pastebin.com/buVHb7Cs

20:51 <Guest44> zmatt, that looks pretty straightforward.  I try it out.  Thanks.

20:52 <zmatt> I've also got some pure-python examples for gpio: https://pastebin.com/1UCnbVNT (minimalistic) and https://pastebin.com/cVHktYPn (more thorough)

20:56 <Guest44> The GPIOs are working ok for me, but I might need those so thanks.

20:56 <zmatt> sure, whatever works works

20:59 <zmatt> I'm personally a fan of using the (non-mainline) gpio-of-helper driver to declare what gpios are to be exprted to userspace, their initial direction (and output level for outputs), and whether userspace may change direction, and then use udev to create symlinks based on their declared name so that userspace doesn't need to know or care about gpio numbers

21:00 <zmatt> but your buildroot kernel presumably doesn't even have that driver

21:00 <Guest44> I don't think it does, but I'm just using the stock kernel from the beaglebone defconfig.

21:02 <zmatt> I don't know anything about buildroot really

21:05 <zmatt> the gpio-of-driver is included in rcn's kernels for the beagleboard.org debian releases, it's a really simple driver whose purpose is to do what I just described above, e.g.: https://github.com/mvduin/overlay-utils/blob/master/gpio-demo.dtsi#L23-L73
