mx28: load kernel into nand flash faild

[hwo]

Hi all,

   I have a mx28evk board with a Micron MT29F1G08ABADAWP  Nand flash. Totally 128MB and  2K + 64 page size.  When I update the firmware using MFGTool, I keep seeing the "Attempt to write not page aligned data" error.

NFC: Version 1, 8-chip GPMI and BCH

Boot ROM: Version 1, Single-chip boot area, block mark swapping supported

Someone knows what happened? Kernel version is 2.6.35.3

I just add the flash's nand_device_info entry in nand_device_info.c. Except this nothing changed with nand driver.

Thanks in advance!

I try to use another command: $ kobs-ng init $FILE in ucl.xml, this time the aligned error disappear, but with a new one problem: Couldn't discover Boot ROM version

Still don't know what has happened.

How lucky! I find the reason according to kobs-ng error  . Thanks to Dan.
