Dear All,
I want to use the k9f2808 NAND flash on my mx1ads board, and I
use kernel 2.4.27 version. Also, the nand_scan function can sucussfully
read the manufacture id and vendor id from my nand flash, but when boot up,
it will pop up such following message, it seems that the kernel try to
erase the NAND flash but failed and the whole kernel halt.
Anybody has encounterred such a situation. I really got a
headache on my NAND device. Thanks for you help.
The kernel boot up information is as below:
Linux version 2.4.27-vrs1-ssl7 (root@localhost.localdomain) (gcc version
3.2.3) #22 五 10月 21 18:01:05 CST 2005

Because the NAND flash hasn't change the order of the mtd minor number, the
root filesystem should be still norflash.But the mounting of root fs
failed. I am puzzled about it.
Thanks for you kindly help.
