Try finding the offending commit with git-bisect: git bisect good v2019.01.0 git bisect bad v2020.01.0 # build, flash, run barebox git bisect good # if it works git bisect bad # if it doesn't work There have been 1004 revisions between the two tags, which means, a binary search will find the offending commit in 10 iterations. When you've found the commit and need to take a more thorough look (printf-debugging), you can add low level UART debug support to your board. Keep us updated!
