This may not be related to Buildroot, but I am completely stumped:
# ls -al /dev/mtdblock*
brw-r----- 1 root root 31, 0 Dec 3 12:26 mtdblock0
brw-r----- 1 root root 31, 1 Dec 3 12:26 mtdblock1
brw-r----- 1 root root 31, 2 Dec 3 12:26 mtdblock2
brw-r----- 1 root root 31, 3 Dec 3 12:26 mtdblock3
#
#
#
# cp mtdblock2 /dev/mtdblock2
#
# ls -al /dev/mtdblock*
brw-r----- 1 root root 31, 0 Dec 3 12:26 mtdblock0
brw-r----- 1 root root 31, 1 Dec 3 12:26 mtdblock1
-rw-r--r-- 1 root root 6815744 Dec 7 17:58 mtdblock2
brw-r----- 1 root root 31, 3 Dec 3 12:26 mtdblock3

Running 2009.11 on PXA255 with a 2.6.27.39 preemptible kernel, EABI,
running the same patches used for 2.6.27.10 (OABI and non-preemptible)
where it worked.
mtd_debug write /dev/mtd2 0 0x680000 mtdblock2 works, results does not
seems correct for /dev/mtd1.
Does anyone know where to look, so far I strike out on the google searches.
