Hello all!
When testing a board with a RK3588 CPU, I get a stable crash on memtest.
This is the first sample of the board on this CPU and of course it is possible
that something is really not soldered correctly, but should the
bootloader crash in this case?

Can you access 0x3fc000200 using md/mw?

Hello.
The dump does not cause a crash, but the output is very strange:

| commit d8a6e1c2662aad2f5d9b4050a276b8e6b9fbb3b1
| Author: Jan Luebbe <jlu@pengutronix.de>

|
| 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.

So far I have isolated several memory pages using reserved-memory:
<0x3 0xfc000000 0x0 0x500000>
and
<0x3 0xfff00000 0x0 0x100000>
So it looks like there is a memory chip bug.

Hello All!
Update: I have start the second board and got similar errors.
Analysis of the code (at the 0x3fc000000), before the memory area
that is not available (at 0x3fc000200) is very similar to the code
from sdram-init.bin.
Maybe we are missing a description of some necessary memory area?
Thanks!
