Other Parts Discussed in Thread: TPS65219
Hello,
So I was able to make a little bit of progress outside of the saveenv issue in the related post. I can manually run "setenv mmcdev 1" and then run the flashall.sh script to flash the SD card. I can then reboot and manually set the mmcdev again to 1 and then run a boot command to load the kernel.
However the kernel seems to crash during startup and android does not successfully boot. After a while the AM62 reboots and runs through u-boot again:

You can see in line 69 the last line of kernel output before u-boot runs again. Any thoughts on why the kernel isn't running successfully?
