Hello Scott,

I want to use jffs2 too, so I modified my "altera.c" in the drivers/mtd/maps since I use an Altera Eval Kit (Cyclone). I modified my mapping to add my partition.

When I boot I get this messages, taht seems ok. 

Altera NDK flash (AMD): Found 1 x8 devices at 0x0 in 8-bit bank
 Amd/Fujitsu Extended Query Table at 0x0040
Altera NDK flash (AMD): CFI does not contain boot bank location. Assuming top.
number of CFI chips: 1
cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness.
cmdlinepart partition parsing not available
RedBoot partition parsing not available
Using Altera NDK partition definition
Creating 5 MTD partitions on "Altera NDK flash (AMD)":
0x00200000-0x00500000 : "romfs/jffs2"
0x00500000-0x00600000 : "brolbrol"
0x00000000-0x00200000 : "loader/kernel"
0x00600000-0x00700000 : "User configuration"
0x00700000-0x00800000 : "safe configuration"

My problem is that when I want to mount it, I don't see the partition in /dev or else... What is the argument I must use with mount ?

Is this something like :

mount -t jffs2 ??? /temp/flash_mount

Thanks a lot
