The board has an ethernet interface, so enable DHCP for it. The used flash chip uses 16K erase blocks, so use that for JFFS2: mtdinfo -a .. mtd5 Name: user Type: nand Eraseblock size: 16384 bytes, 16.0 KiB Amount of eraseblocks: 1915 (31375360 bytes, 29.9 MiB) Minimum input/output unit size: 512 bytes Sub-page size: 256 bytes OOB size: 16 bytes Character device major/minor: 90:10 Bad blocks are allowed: true Device is writable: true While we're at it, add a readme explaining how to build and upload the build to the board.

Openblocks A6
Intro
=====
This default configuration will allow you to start experimenting with the
buildroot environment for the Openblocks A6. With the current configuration
it will bring-up the board, and allow access through the serial console.
How to build it
===============
Configure Buildroot:
$ make openblocks_a6_defconfig
Compile everything:
$ make
Updating board over TFTP
========================
Copy the content of output/images to the root of your TFTP server.
Connect serial and ethernet, power up board and stop it in U-Boot:
DRAM (DDR2) CAS Latency = 5 tRP = 5 tRAS = 14 tRCD=5
DRAM CS[0] base 0x00000000 size 512MB
DRAM Total size 512MB 16bit width
Addresses 8M - 0M are saved for the U-Boot usage.
Mem malloc Initialization (8M - 7M): Done
NAND:64 MB

Load kernel from tftp:
setenv serverip <tftp-server-ip>
setenv bootfile uImage.kirkwood-openblocks_a6
bootp && tftp
Write it to nand:
nand erase 0x590000 0x1c5c000
nand write.e $loadaddr 0x590000 0x1c5c000
Load rootfs from tftp:
setenv serverip <tftp-server-ip>
setenv bootfile rootfs.jffs2
bootp && tftp
Write it to nand:
nand erase 0x2214000 0x1dc4000
nand write.jffs2 $loadaddr 0x2214000 0x1dc4000
Configure kernel to use rootfs:
setenv root /dev/mtdblock5 rootfstype=jffs2
saveenv
