The Routerboard RB433UL is currently not supported. This Board was initally based upon Atheros AR7161 400MHz CPU but now it is based upon Atheros AR7130 300Mhz CPU. RB433UL has 64MB RAM and the serial console is not supported by uboot.
Remark: There are two Resets: Reset 1 (Button) and Reset 2 (Pad).
Sometimes you must press both.

Here are the three main steps of the installation:
The bootloader of RB433 is able to load an image in elf format via BOOTP into RAM and execute it.
If you are not comfortable with building your own trunk you can get the image from official OpenWRT download servers as of 14.07 release:
You need to get OpenWrt trunk. In menuconfig choose:
Now build the ram disk version. While it's building create the tftp-root directory if not already done and a symlink to the ram disk image
sudo mkdir -p /tftpboot sudo ln -sf $(HOME)/openwrt/rb433uah-netboot/bin/ar71xx/openwrt-ar71xx-nand-vmlinux-initramfs.elf /tftpboot/openwrt.elf
You need a BOOTP and a TFTP server on your host machine, we use
dnsmasq here, since it can provide both services. Install dnsmasq with:
sudo apt-get install dnsmasq
Changes in /etc/dnsmasq.conf:
(replace the XX with the MAC address of your board!)
Finally restart dnsmasq
sudo /etc/init.d/dnsmasq restart
You will probably need to set the IP of the interface manually:
sudo ip addr add 192.168.6.1/24 dev eth0
If everything is setup correctly it should look like:

You need a working netboot first, see above. Please note also that you cannot reflash from a previous OpenWrt installation, you need the netboot in any case.
If you want to use the same trunk image as the netboot image (cf. above), you need to have the tar.gz target selected in the Target Images menu and rebuild if you didn't select it before. You can also use one of the pre-built images (tested with 12.09-rc2); in the download area, browse the
ar71xx/nand/ directory and pick the two following files:
Update: For 14.07 release images are provided at
If you don't have many devices to install and your netbooted system can access the Internet, you can probably pass the download URL directly to wget2nand as well, that will save you the web server configuration step (see below).
If you have access to the MikroTik's Winbox software, you can export the license file from System→Licence, as stated on the RouterBoard 411 page.
Otherwise, boot RouterOS and export the key to a file:
/system license output
Then list the files on your device to see which file the .key file was saved:
On a fresh install, the key file should be #1 (or #0 on a RB433UAH); to open the editor with file #1, type:
/file edit 1 value-name=contents
Then copy-paste the text in a file on your computer. The differences between the obtained key file and a key exported with Winbox are that the SoftwareID line is not present in the latter, and there are no empty lines, so you should probably delete all the empty lines in your file prior to import it for a new installation; the SoftwareID line should not bother the installer (untested).
If you want to install OpenWrt permanently into the NAND flash you once need to erase the NAND flash to get rid of the RouterOS stuff:
An HTTP web server is required on the host, e.g. mini-httpd in Ubuntu. Install the mini-httpd web server
sudo apt-get install mini-httpd
Restart the mini-httpd web server
sudo /etc/init.d/mini-httpd restart
This script will set an IP address via dhcp on br-lan. The output should look like:

The MicroSD Slot needs SPI-Bus sharing support, which is not implemented in Backfire.
SPI-Bus sharing has been implemented in Trunk r22862 the MicroSD Slot is usable now. Read speed ist about 0.92 MB/s (11/13/10: I get I/O and -89 errors on the SPI bus while assessing the microSD card).
The ethernet jacks are mapped to port numbers of the IP175C switch (looking at the front of the board):
[ port 4 (PoE)] ( serial ) [port 1] [port 2]
|eth1||1 & 2|
Port 1 and port 2 are switched in the default config.
