The device is supported in OpenWrt since Kamikaze.

This article will be completed soon, see oldwiki now.

If you flash OpenWrt from NetBoot facility, you will lose your RouterOS licence.

The installation of OpenWrt on this board is only possible by using the NetBoot facility - you will boot into the RAMdisk version of OpenWrt and use it to flash the permanent OpenWrt image into NAND. You will need:

1. A serial port (or a USB-RS232 serial converter) and a null modem cable as console (standard serial cable wont work).
2. An ethernet port and cable to download the NetBoot kernel and the NAND image.
3. A DHCP server to tell the RB1xx where to get it's netboot image (e.g. DnsMasq).
4. A TFTPD server to supply the NetBoot image to load a barebone OpenWrt RAMdisk image (e.g. DnsMasq).
5. A web server to serve up the permanent version of the OpenWrt kernel and rootfs (you can use SCP as well).

Connect your RouterBoard using both ethernet and null modem cable to a PC.

See official howto for more info.

If you select the squashfs image, it may take quite a few minutes for the device to power on.

You will have to run the building process twice, because you will need both RAMdisk image and stock OpenWrt kernel+rootfs.

Build profile should be:

• Target System:
• Target Profile:

Disable ANY firewall on your PC.

1. Download Putty, run it, select Connection type: Serial, Serial line: COMx (x = number, depends on your configuration), Speed: 115200, and Open.

Atheros-based card are supported. The device doesn't work with Broadcom cards, since kmod-ssb causes kernel panic at startup.
