MikroTik Routerboard RB532(A)
These units still show up on ebay occasionally for $35-64. They normally run MikroTik's RouterOS but were also available with a Debian GNU/Linux image.

Installing image via CompactFlash Card
Get the openwrt-rb532-combined-jffs2-128k.bin file. Write this file to an 8MB or larger Compact Flash card using the following command (assumes your Compact Flash is accessible as /dev/sde):
dd if=openwrt-rb532-combined-jffs2-128k.bin of=/dev/sde
Insert the CF into the board. Connect to board via serial terminal of your choice with 38400 8N1. If you use screen the line is:
screen /dev/ttyS0 38400 81N
Apply power to the board. The default boot delay is short, so the first time using a board you will have to be fast to interrupt the boot process by pressing enter. This is what you see then:
RouterBOOT booter 2.9 RouterBoard 532 CPU frequency: 333 MHz Memory size: 32 MB Press any key within 2 seconds to enter setup RouterBOOT-2.9 What do you want to configure? d - boot delay k - boot key s - serial console o - boot device u - cpu mode f - try cpu frequency c - keep cpu frequency r - reset configuration e - format nand g - upgrade firmware i - board info p - boot protocol t - do memory testing x - exit setup your choice:
At this point you may want to choose d - boot delay in order to increase the boot delay to ease using the serial console. Next select e - format nand and you should see the following:
Do you realy want to format your nand? that would result in losing all your data type "yes" to confirm:
Respond by typing the word yes The system should respond as follows:
formating nand... done! RouterBOOT-2.9 What do you want to configure? d - boot delay k - boot key s - serial console o - boot device u - cpu mode f - try cpu frequency c - keep cpu frequency r - reset configuration e - format nand g - upgrade firmware i - board info p - boot protocol t - do memory testing x - exit setup your choice:
At this point you should select o - boot device which results in the following:
Select boot device: e - boot over Ethernet n - boot from NAND, if fail then Ethernet c - boot from CompactFlash only 1 - boot Ethernet once, then NAND 2 - boot Ethernet once, then CompactFlash * o - boot from NAND only b - boot chosen device your choice:
You should select c - boot from CompactFlash only which result in the following:
RouterBOOT-2.9 What do you want to configure? d - boot delay k - boot key s - serial console o - boot device u - cpu mode f - try cpu frequency c - keep cpu frequency r - reset configuration e - format nand g - upgrade firmware i - board info p - boot protocol t - do memory testing x - exit setup your choice:
Select x -exit setup which will write the settings to flash and then reboot from the CompactFlash card. Once booting has completed you may continue with configuring OpenWrt.
Upgrading OpenWrt
If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
LuCI Web Upgrade Process
- Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
- Upload image file for sysupgrade to LuCI
- Wait for reboot
Terminal Upgrade Process
- Login as root via SSH on 192.168.1.1
- Use the following commands to upgrade.
cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
- If sysupgrade does not support this router, use the following commands.
cd /tmp/ wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot
Basic configuration
→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.
