I'm not that familiar with partitions in Barebox. On my i.MX27 board, I now have :
barebox:/ devinfo
devices:
|----imx_serial0
|----cs0
|----ramfs0
|----devfs0
|----mem0 (defaultenv)
|----mem1 (mem)
|----imx_spi1
|----mc137830 (pmic)
|----mem2 (ram0)
|----imx_nand0
|----nand0 (nand0, nand_oob0, self_raw, env_raw, nand0.barebox, nand0.bareboxenv, nand0.kernel, nand0.root)
|----fec_imx0
|----miidev0 (phy0)
|----eth0
drivers:
imx_serial
ramfs
devfs
fec_imx
miidev
imx_nand
cfi_flash
imx_spi
imxfb
mc13783
mem
barebox:/
and :
barebox:/ ls -l /dev
cr-------- 4294967295 zero
crw------- 6125 defaultenv
crw------- 4294967295 mem
crw------- 256 pmic
crw------- 134217728 ram0
crw------- 268435456 nand0
cr-------- 8388608 nand_oob0
crw------- 32 phy0
crw------- 262144 self_raw
crw------- 262144 self0
crw------- 131072 env_raw
crw------- 131072 env0
crw------- 262144 nand0.barebox
crw------- 131072 nand0.bareboxenv
crw------- 2097152 nand0.kernel
crw------- 265945088 nand0.root
barebox:/
I think this looks OK.
However, I expected this to work (I took this from descriptions on the Internet...) :
barebox:/ erase /dev/nand0.kernel.bb
stat /dev/nand0.kernel.bb: No such file or directory
barebox:/
and
barebox:/ tftp zImage /dev/nand0.kernel.bb
open: Read-only file system
barebox:/
Is there any documentation that handles/describes this ? (e.g. what's the extension .bb ?)

The .bb extension means a bad block aware partition. Use the 'nand -a' command
to create one from a raw NAND partition, e.g. 'nand -a /dev/nand0.kernel'.

[Filip] Shouldn't I have automatically /dev/mtdblock* devices, e.g. /dev/mtdblock7 for rootfs nand partition ?

'bb' means "Bad Block", and defines a layer that is bad block aware, and can
handle it in a correct manner.
Add "CONFIG_GLOB=y" to make a script work, that add the *.bb names to all
existing nand partitions.
