I'm thinking of making a new Beaglebone Black variant with USB-C support built
in (primarily for power). I think I'll just include some kind of FTDI chip on
board.

It was really confusing. I put the Jessie lxqt flasher on the SD card, and
that’s what I got (the BBB eMMC had something from 2016 on it).
I was able to get the latest-releases stretch from 2018-01-28 (?) to load just
fine (never once tried the boot button).

Now it's running a SoftAP that asks for a password.

I'm working on a U-boot overlay, but while experimenting, is there a way to

wanted to make sure there wasn't a more specific reason why the green
version of the file doesn't exist.
I used am335x-boneblack-audio-emmc.dts, and it seems to work fine in
4.4.7-bone-rt-r9 (aside from the other audio issues that arise).

I can't remember where I saw it, but it was a kernel-related BeagleBone Black
repo. There was a config file (maybe amixer?) for use with the AudioCape.
Robert, do you know what I'm remembering and where it is?

an ALSA config problem, but I need to get to a working state to try to figure

I keep forgetting to make sure I re-enable eMMC, and then get hosed when I
reboot after installing a new kernel.
Is there a reason eMMC is disabled in these (I just tried 3.19.3)?

I found that to be virtually impossible to do in any comprehensive way, not
already understanding it. Can't use printk() if you don't know where to put it.

What would I need to get/do to enable me to single-step through kernel code on
BBB/G? JTAG header, some kind of interface, and a bunch of software installed

One possibility, ALSA is still not configured correctly for this cape, but I
wonder if anyone has the right configuration for it?
Thanks!
