Subject: [U-Boot] U-boot issue with Intel StrataFlash P30.
Date: Fri, 10 Sep 2010 18:30:19 -0300	[thread overview]
Message-ID: <1284154219.13384.13.camel@parana.digitel.com.br> (raw)

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
