Message-ID: <1284154219.13384.13.camel@parana.digitel.com.br> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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?
