Hi,
I am porting the u-boot to a MPC8536E custom board and I am facing an
issue with flash. When u-boot tries to detect the flash (INTEL
STRATAFLASH P30) it just freeze. The u-boot is started from the same
flash.
The problem happen when the CFI Driver tries a read from flash
(flash_read8()) for the first time. Please, see the log bellow.
Has someone faced this kind of issue? Are there some tip to solve the
problem?
Thank you,
Moratelli
