Yes, I am trying. But it is weird on my side.

- my driver use ECC_SW then can eraseall flash, mkyaffs flash and mount
the mtdblockX. Then copy all rootfs files to the mtdblockX yaffs2,
kernel can boot from this yaffs2.

- but when try flash_eraseall and nandwrite to supporting JFFS2 with the
same driver. When mounting JFFS2 mtdblockX, it trys to nand_read_oob
then the whole system hang. I will debug this.

- When enable ECC_HW in my driver, yaffs2 mount and write will cause ECC
error. That maybe is my driver ECC_HW's problem.

Thanks a lot for your help.
