I have a fix for mtd driver, that allows to erase and reflash bootrom partitions on the fly. If interested, take it from http://www.luban.org/Webpal

Enjoy. Reports welcome as always.

Vit,

What do I need to do to utilize your mtd driver? I have tried
your image, I did a:

cd /dev
mknod mtd0 c 90 0
mknod mtd1 c 90 1
mknod mtd2 c 90 2
mknod mtd3 c 90 3
mknod mtdblock0 b 31 0
mknod mtdblock1 b 31 1
mknod mtdblock2 b 31 2
mknod mtdblock3 b 31 3
chmod 600 mtd*

but when I try to do an erase /dev/mtd3 I get
a File open error.

I know I must be missing a very important step...???

It looks like your minor numbers for /dev/mtd[1-3] are not quite right. Here's what I have. This works for me with the kernel image I posted a few days ago:

crw-r--r-- 1 root root 90, 0 Jan 15 11:15 /dev/mtd0
crw-r--r-- 1 root root 90, 2 Jan 15 11:15 /dev/mtd1
crw-r--r-- 1 root root 90, 4 Jan 15 11:15 /dev/mtd2
crw-r--r-- 1 root root 90, 6 Jan 15 11:15 /dev/mtd3

brw-r--r-- 1 root root 31, 0 Jan 15 11:15 /dev/mtdblock0
brw-r--r-- 1 root root 31, 1 Jan 15 11:15 /dev/mtdblock1
brw-r--r-- 1 root root 31, 2 Jan 15 11:15 /dev/mtdblock2
brw-r--r-- 1 root root 31, 3 Jan 15 11:15 /dev/mtdblock3

Scratchy, Tnx a mill! That was the problem.

I'm having a ball with this webpal, and learning tons as I progress.
I thank you and others here mucho for the pointers and support.

Coming from newbeedom, I'm not sure how I would have known about the
mknod of 0,2,4,6 -vs- 0,1,2,3 would appreciate any comments on that
so I can tuck it away in the cranium void...

I built the erase utilities by downloading the latest mtd-snapshot source. I then looked in the script mtd/util/MAKEDEV to learn how mknod should be run. That's the only reason I know about the 0,2,4,6 numbering.
