Message-ID: <456DAD9C.4040708@aotek.es> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hi all, We have a MPC5200B based custom board with a ST Microelectronics M29W320B (x8/x16 flash in x8 mode) as boot flash. We are able to program the flash using a BDI2000 and start up U-Boot. But U-Boot is unable to detect the boot flash using the CFI driver. With the same hardware (but other board) and a flash from other vendor (Spansion S29GL32A) the CFI driver works properly. Has anyone tested the CFI driver for the M29W320B flash? This is the BDI2000 output when we write a CFI Query command ffc00000 : 2000 5722 FFFF FFFF FFFF FFFF FFFF FFFF .W"............ ffc00010 : FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF ................ ffc00020 : 5100 5200 5900 0200 0000 4000 0000 0000 Q.R.Y..... at ..... ffc00030 : 0000 0000 0000 2700 3600 b500 c500 0400 ......'.6....... ffc00040 : 0000 0a00 0000 0400 0000 0300 0000 1600 ................ ffc00050 : 0200 0000 0000 0000 0200 0700 0000 2000 .............. . ffc00060 : 0000 3e00 0000 0000 0100 0000 0000 8000 ..>............. ffc00070 : 0000 3e00 0000 0000 0100 FFFF FFFF FFFF ..>............. ffc00080 : 5000 5200 4900 3100 3000 0000 0200 0100 P.R.I.1.0....... ffc00090 : 0100 0400 0000 0000 0000 b500 c500 0200 ................ ffc000a0 : FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF ................ ffc000b0 : FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF ................ ffc000c0 : FFFF 6012 4e3b f07d 9b54 3500 2002 2003 ..`.N;.}.T5. . . ffc000d0 : 1200 2700 3a00 0100 0000 0000 0000 0000 ..'.:........... ffc000e0 : 0000 0f00 0700 0200 0000 0100 0100 0000 ................ ffc000f0 : 0000 0000 0000 0100 0000 0000 0000 0000 ................
