Subject: [U-Boot-Users] Problem in CFI driver (Spansion flash 8-bit mode)

Hai,
    I am using MPC8641D processor. 16MB flash with 8bit mode(part
number:S29GL128N90FFIRR). From the BDI prompt i am able to prog the uboot.
The output is

8641>md 0xfff00000
0_fff00000 : 27051956 552d426f 6f742031 2e322e30  '..VU-Boot 1.2.0
0_fff00010 : 20284a75 6e203239 20323030 37202d20   (Jun 29 2007 -
0_fff00020 : 31333a32 313a3432 29000000 00000000  13:21:42).......

   Then i give the go command in the BDI prompt means the uboot booted i got
the prompt. From the u-boot prompt i try the erase the flash and program i
get the following result.

MPC8641D-AMC> md 0xfff00000
fff00000: 05275619 2d556f42 746f3120 322e302e    .'V.-UoBto1 2.0.
fff00010: 2820754a 206e3932 32203030 2037202d    ( uJ n922 00 7 -
fff00020: 3431333a 3a383630 00290000 00000000    413::860.)......

   the result looks like swapped. The u-boot version is 1.1.6. processor
d7-d0 is connected to flash d0-d7. Byte pin in the flash is connected to the
ground. it indicates 0 -> 8bit mode.

   How can i overcome this problem? Does the currect cfi driver in uboot
support 8bit mode or not? if it is means why i got this problem? 

Thanks,
         Laba
