Hi,
i try to create a programm which is able to update the uClinux on my cm-bf537e modul.
I want to copy the uImage.ext2 into my SD-Card and afterwards run netflash to update my flash.
The problem is that netflash is not running correctly....
root:/> cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00020000 "U-Boot"
mtd1: 003c0000 00020000 "uClinux"
mtd2: 00500000 00001000 "ROMfs"
root:/> netflash -k -r /dev/mtd1 /media/uimage.ext
netflash: offset is greater than device size (0)
root:/>
I also try mtdlock2 instead of mtd2 but there is the same problem.
When i try to use netflash without -r there is another problem.
root:/> netflash -k /media/uimage.ext
netflash: open(/dev/flash/image) failed: No such file or directory
root:/>
Is there anyone who can give me an example how i can update my uClinux-dist under uClinux?
thanks a lot,
Patrick

Patrick,
I would think using "flashcp" in mtd-utils would be better? (But it looks the flashcp does not get built by default in our release). I will have a check.

Hi Patrick, I'm having exactly the same problem with netflash. I've been using the 'dd' command to get the job done.
dd if=/image of=/dev/mtdblock3
You must use this on a block write device in order for it to work properly.
DD is NOT the best way to do this, and it has caused me many headaches due to lack of error checking/handling ability.
Mike? Robin? Can anybody shed some light on what might be going on with netflash? I assume we must be overlooking something...
Thanks!
