See: | commit d8a6e1c2662aad2f5d9b4050a276b8e6b9fbb3b1 | Author: Jan Luebbe | Date: Sun Aug 3 17:51:38 2014 +0200 | | ARM/mem: handle data aborts gracefully for md | | Sometimes memory ranges contain inaccessible registers which trigger a | data abort when accessed. To handle this gracefully, we extend the data | abort exception handler to ignore the exception when configured to do | so. | | This allows detecting inaccessible memory from the md command. It will | show XX for unreadable bytes instead. I don't know why you get a data abort here. The answer is probably somewhere in the DMC section of the RK3588 reference manual.
