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

Try using recent code instead (v2010.09-rc1).
Best regards,

Might be that you have problems with byte access to this most likely 16bit
wide flash device. I suggest you try setting this in your board config header:
#define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_16BIT
Cheers,
Stefan
