eMMC errors on RK3588 (rock5b)

[Eugen Hristev]

Hi Jonas,

I tried some basic eMMC read/write commands, and in my setup with 
rock5b, it fails at single/multiple block read/write , even if 
sometimes, the initial read works fine.

Here is some log :

So now after this attempt, there is a timeout when reading too.


Can you try to reproduce this on your setup as well ?

P.S. booting from eMMC works fine. When I am trying this, I am booting 
from the eMMC.

Thanks !
