Hi,

I have a 16MB, M29EW flash on target boards.

I got the below info, while probing the flash.

Bank # 1: CFI conformant flash (8 x 8)  Size: 64 MB in 512 Sectors
  AMD Standard command set, Manufacturer ID: 0xFF, Device ID: 0xFF
  Erase timeout: 4096 ms, write timeout: 2 ms
  Buffer write timeout: 5 ms, buffer size: 1024 bytes

Since the Manu.ID of this flash is 0x89, it got detected as 0xFF.

Does u-boot code have a support for M29EW flash..?

Thanks,
Jagan.
