i am compiling a new jffs2 image for an embedded device, and i get an
error saying my erase size is wrong.
how do i determine what is my erase size ? (so i can compare to a
jffs2 file that works)
is there a utility that can give info on jffs2 images, like what is
their erase size ?
Not that I know of, but assuming you can boot that working jffs2 image
you can ask the Linux kernel what is the erase block size.
target$ cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00010000 "bootloader"
mtd1: 00020000 00010000 "params"
mtd2: 00400000 00010000 "kernel"
mtd3: 00bc0000 00010000 "filesystem"
Note the "erasesize" column.
Hope this helps,
Gilad
