So far I’ve built/tested on black using u-boot/kernels and rootfs from Robert’s wiki page and encountered a few issues.
- focal rootfs has network issues and fails on network up/ttyG, then freezes without a console prompt (kernel 5.4 or less) whereas bionic boots successfully.
- with latest debian flashed to emmc, using uEnv.txt on both emmc and sdcard has some issues with newer kernels; 5.10 kernel has mmc0/1 swapped from both earlier kernels and u-boot.
- beaglebone-yocto (dunfell branch) boots fine, uses vfat /boot and extlinux.conf
- using extlinux.conf on sdcard boots reliably (with debian/uEnv on emmc) using bionic and 5.10 kernel
Hopefully building from meta-ti should also work, but I didn’t find an image recipe or doc to get a nice TI dev image with PRU stuff, etc.
Right now I don’t have an answer for munging uEnv.txt on sdcard to make it happy with Robert’s default setup.
