Sep 17 08:21:17 <zmatt> vd: one of the regulators of the pmic, specifically the one for vdd_1v8 (the main 1.8V supply)
Sep 17 15:11:35 <the_person48> hi guys, I am running debian 9.5 on a beaglebone black rev C. I am working on setting up a boot overlay for the GPIO and other pins. I cloned overlay-utils and show-pins from github to do the overlay, and check the configuration, respectively
Sep 17 15:12:14 <the_person48> the overlay seems to be working! however, when I then added udev rules to name the gpio and adc pins in /dev, I encountered two issues:
Sep 17 15:12:41 <the_person48> 1) the names for the gpio pins are screwed up--they are mostly not the names I gave them, and the total number is wrong as well
Sep 17 15:12:50 <the_person48> 2) the adc pins don't show up at all for some reason
Sep 17 15:13:06 <the_person48> I was wondering if anyone knew why either/both of these might be occuring?
Sep 17 15:13:17 <the_person48> here are my udev rules. in /etc/udev/rules.d:
Sep 17 15:13:28 <the_person48> gpio-symlinks.rules:
Sep 17 15:13:28 <the_person48> https://pastebin.com/RHpxYLuq
Sep 17 15:14:18 <the_person48> and ain-symlinks.rules: https://pastebin.com/t0wFVERT
Sep 17 15:14:57 <the_person48> this is my dtsi overlay, which I compiled using overlay utils "make new_boot_overlay.dtbo", compiled succesfully: https://pastebin.com/GCRw9E0m
Sep 17 15:15:31 <the_person48> notably, the gpio names seemed to be working better before I gave them the physical pin names (P8_24, P9_15, etc.)
Sep 17 15:15:40 <the_person48> so possibly this is part of the problem? not sure
Sep 17 15:16:06 <the_person48> also, here is my /boot/uEnv.txt (not sure if it's relevant): https://pastebin.com/sA7X3wT7
Sep 17 17:17:11 <the_person48> update: I tried changing the names on the overlay to PP8_24, PP9_15, and now the /dev/gpio directory contains these names
Sep 17 17:17:46 <the_person48> seems like there's something that doesn't want me to name them the physical pin names? Is there a way around this? Because I do want to refer to them by P8_24, P9_15, etc., later in the file tree
Sep 17 17:18:02 <the_person48> despite the overlay. they were named that before the overaly
Sep 17 17:18:31 <the_person48> also the /dev/adc pins are still not showing up; no adc/ directory in /dev
Sep 17 17:20:34 <the_person48> do I need to uncomment the: #disable_uboot_overlay_adc=1
Sep 17 17:20:43 <the_person48> line in /boot/uEnv.txt or something along those lines?
Sep 17 18:29:54 <the_person48> sorry lost connection but back now
Sep 17 18:30:00 <the_person48> (for about the last hour)
Sep 17 19:24:21 <the_person48> also, I noticed that I'm missing P8_3 in my /dev/gpio directory
Sep 17 19:24:38 <the_person48> even though I have it defined analagously to the others (that are all working) in the overlay, like this:
Sep 17 19:24:55 <the_person48> PIN_PULLDN( P8_03, 7 )  // gpio 1.6
Sep 17 19:25:09 <the_person48> PP8_3 {
Sep 17 19:25:10 <the_person48>                         gpio = <&gpio1 6 ACTIVE_HIGH>;  // P8.3
Sep 17 19:25:10 <the_person48>                         output;
Sep 17 19:25:11 <the_person48>                         init-low;
Sep 17 19:25:11 <the_person48>                 };
Sep 17 19:25:30 <the_person48> full overlay is here:
Sep 17 19:25:32 <the_person48> https://pastebin.com/GCRw9E0m
Sep 17 19:26:01 <the_person48> although I changed all the names to be like "PP8_4" instead of "P8_4" cause I'm still encountering weird issues with the pins having the wrong names in /dev/gpio otherwise
