Xiaomi Redmi 4A porting process
I'm making a port for Xiaomi Redmi 4A (rolex). It's still WIP, but there is some progress:
- kconfig check passes;
- the kernel boots.
However, I'm encountering problems. After flashing to the SD
card I try to boot the kernel using
pmbootstrap flasher boot.
After that, I get the error
remote: dtb not found. When I try
to boot it again, the phone's screen becomes black and another
status read failed (No such device).
It shows up in

There's no additional network interface, initramfs hooks don't seem to do anything.
