Your pwm controller is not setup right, 517 should be deferred probe (try later because depencies missing),but i do not see a later attemptā€¦there are also pcie errorsā€¦have you modified code/dts of your kernel?

I do not modify code/dts of kernel.

you should open a new topic as this is for r64 and completely different. and please do not create 3 postings in same thread in a few minutesā€¦you can edit your postings to add additional information ("ā€¦" and then the pen)

you should also first try with official openwrt and then switch to the specific fork.
