dieselnutjob If you manage to compile 5621/5622 for 6.1 please let me know, it can be in this thread. Btw. I solved this problem above, don't know what exactly caused the problem, but I used a different defconfig (linux-5.16-sunxi64-current.config) and it compiled and linked without errors. Maybe I will compare my current and previous defconfig to see the difference.
