Problem: erase mtd device
This is what I got after I added three custom partitions in the physmap.c:
After the kernel (2.4.20) boots up, I logged in as root and type:
#cat /proc/mtd
== and I got:
dev: size erasesize name
mtd0: 00040000 00040000 "ResetWord"
mtd1: 01ec0000 00040000 "User FS"
mtd2: 00100000 00040000 "UBOOT"
The size, erasesize and name look correct. It does not say the starting point of each partitions. Since our first and third partition are write-protected, so I tried to erase the mtd1.
And I typed:
#erase /dev/mtd1
== and I got:
File open error
And I typed:
#eraseall /dev/mtd1
== and I got:
eraseall: /dev/mtd1: No such device
Did I do anything wrong?

try unlocking that device before erasing. my flash (YMMV) powers up to a locked state. (read the rest of this email first)

check your /dev/mtd? entries against ./Documentation/devices.txt are the major/minor numbers correct?
