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
