Thanks Dennis! This is what I ended up doing:
1) I flashed an SD card with this image: https://debian.beagleboard.org/images/am57xx-debian-9.9-lxqt-armhf-2019-08-03-4gb.img.xz 2) Booted up the BBAI with the SD card in. 3) sudo mkdir /mnt/emmc 4) sudo mount -t ext4 /dev/mmcblk1p1 /mnt/emmc 5) Edited /mnt/emmc/boot/uEnv.txt and switched the kernel back 6) sudo shutdown -h now 7) Removed the SD card 8) Booted back up successfully from the eMMC This post was helpful: https://unix.stackexchange.com/questions/449529/repair-uenv-txt-from-u-boot-terminal On Mon, Apr 27, 2020 at 3:23 PM Dennis Lee Bieber <dennis.l.bie...@gmail.com> wrote: > On Mon, 27 Apr 2020 13:42:44 -0700 (PDT), in > gmane.comp.hardware.beagleboard.user > john-/83Ax2S01hhWk0Htik3J/w...@public.gmane.org wrote: > > >I also don't see anything when I hook up a monitor and keyboard.
