Help: Error on mounting JFFS2

[Shawn Jin]

Hi,

I have some error when mounting a JFFS2 root
filesystem. My flash is Am29PL320D on a MPC8245 board,
16MB at two banks (0xFF800000, and 0xFF000000).
CONFIG_MTD_CFI_B8 and CONFIG_MTD_CFI_I2 are set. The
root fs image has benn programmed to bank 1 which
starts at 0xFF000000. The error message is shown
below.

The following debugging information about the flash
chip may be helpful.
