I'm working toward being able to update my kernel from a running linux
but I've run into a bit of a problem with the mtd-utils package. It's
my understanding that I can update the kernel by erasing the mtd block
where it is stored (/dev/mtd2) and then write the new image to the same
location using nandwrite -p /dev/mtd2 <source image>.
Doing a 'flash_eraseall /dev/mtd2' I get the following message...
r...@dm355evm:~# flash_eraseall /dev/mtd2
Erasing 256 Kibyte @ 3c0000 -- 93 % complete.
The 93% leads me to believe that the application recognizes the chip
improperly since I had the same type of problem in uboot when our
hardware switched from the QAA -> DAA nand chip. (It would calculate
the completion percentage to > 100%).
Going further and trying a nandwrite gives the following error:
r...@dm355evm:~# nandwrite -p /dev/mtd2 /media/usb/uImage.copy
Unknown flash (not normal NAND)
I'm pretty sure that the mtd-utils package just isn't configured to work
with the xxxDAA nand chip but I wanted to first check to see if anybody
on this list has had the same problem? If so, did you edit the source
for mtd-utils to fix it?
Thanks,
BJ
