Subject: [U-Boot-Users] Problem with the ST Microlectronics M29W320B flash and the CFI driver.

Message-ID: <456DAD9C.4040708@aotek.es> (raw)
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

AFAIK the CFI driver is waiting an output like this for a x8/x16 device
in x8 mode:
ffc00020 : 5151 5252 5959 QQRRYY
Am I wrong?
Best regards,
