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
