What works

LAN, Mini-pci, USB

Building bootable image

The generic Bildroot installation creates bootable ramdiskfs image. buildroot.exigence

- I didn't need to install subversion. It was installed by default on my linux desktop.
- I run make menuconfig and choose
* Target System (Atheros71xx/…)
* Subtarget (Device with NAND flash …)
* Target Images → *ramdisk, *tar.gz
- Run make
- The image is in ./bin/ar71xx/openwrt-ar71xx-nand-vmlinux-initramfs.elf
- You need to copy this image into your tftpboot directory.

Boot from network

I started the routerboard with netboot. NetBoot

- Worked fine - remember to open the udp port 69 and high-ports (udp) in your firewall


- It would seem everything is working just like with 433x models.


Building tested on Attitude Adjustment 12.09-RC2. Everything later should work also. Currently no issues observed.
