To install OpenWrt you have to stop the system loading through the serial console. To do that you need a serial adapter/converter (that convert TTL +3.3V of router serial console to RS232 (+/-12V) or USB). I suggest to use USB serial converter!! Don't even try to go further without a serial adapter!!
You can buy USB serial converter adapter on Ebay (find CP2102 chipset), e.g. USB serial adapter based on Silicon Labs CP2102 (Ebay)
The firmware is based on OpenRG, I don't know how to backup this firmware. Continue at your risk!!!
You can try bcm63xx#dump.the.flash. It isn't a firmware backup but a whole flash backup — danitool 2013/01/23 15:23
We need a way to backup it first.
You need to setup a tftp server on some host (I can suggest to use dnsmasq for this) to serve the firmware image to the router.
Now just download the image for A226M from
You have firmwares for two filesystems (squashfs and jffs2)
squashfs is a filesytem that have system files readonly. more stable and less problems. you cannot destroy importan file
jffs2 is a file system completly writable. more powerfull but you can destroy system files.
To start as novice I sugegst to use squasfs firmwares.
Skip the jffs2 with 64k erase block as the flash use 128k block, anyway using 64k should not give much problem, just some wasted space and some errors messages. Put the chosen image in the right place (see your tftp server configuration), and go to the CFE prompt.
Through the serial console and a terminal program (like Hyperterminal, Putty portable, Teraterm) setup as 115200, 8 bit data, no parity bit, 1 stop bit, poweron the router and press any key to stop the system loading.
I suggest to rename the firmware file downloaded as firmware.bin
Now you have to use the flashimage command to load the openwrt image, please don't use the f command. If you configure (with command c) the host ip address you can avoid it in the flashimage argument.
CFE> flashimage eg. flashimage [hostip:]compressed_image_file_name or es: flashimage 192.168.1.100:firmware.bin or es: flashimage firmware.bin
That's all, the device will automatically reboot and openwrt will be there
dnsmasq -d --enable-tftp --tftp-root=`pwd` -p 0 #fron the directory where firmware is previously downloaded
where the 192.168.1.100 is your server tftp After the flashing of new firmware the router will reboot.
You can use also TFTP server like tftp32. Install tftpd32 and put the firmware file (I suggest to rename it as firmware.bin) in the same folder where you installed tftpd32.
ATM (24 jan 2013) the OpenWrt image is rejected due to wrong CRC in kernel
Is this still true today? If this is solved, please update this page accordingly. — tmomas 2015/09/30 15:30

If you receive this error with the test file: openwrt-A226G-cfe-squashfs-cfe.bin I had also prevents this problem and I solved it with this. (31/07/2013)

The serial port is J10, on the left of the switch chip, see photos
Serial connection parameters are 115200 8N1
NB: A short circuit between pins
TX at power up puts the device in a recovery mode with IP
192.168.1.1 from where a new firmware can be uploaded. OpenWrt binaries are refused, though, because of invalid CRC.
Jtag port is J9 near the SoC and the minipci socket, see photos
It seems to be a mips e-jtag 14 pin connector with columns swapped (used from the other side?).

You should probably try the Open On-Chip Debugger
Install OpenWrt on this router
To have a better match with DRG A226M functions, I suggest you to use it with the following network configuration. Using the interneal editor vi, check and edit /etc/config/network file.
For more info read switch config. To be reviewed
config interface loopback option ifname lo option proto static option ipaddr 127.0.0.1 option netmask 255.0.0.0 config 'switch' 'eth1' option 'enable' '1' option 'enable_vlan' '1' option 'reset' '1' config 'switch_vlan' 'vlan0' option 'vlan' '0' option 'device' 'eth1' option 'ports' '0 1 2 5t' config 'switch_vlan' 'vlan1' option 'vlan' '1' option 'device' 'eth1' option 'ports' '3 5t' config interface lan option ifname eth1.0 option type bridge option proto static option ipaddr 192.168.5.1 option netmask 255.255.255.0 option nat 1 config 'interface' wan option 'ifname' 'eth1.1' option 'proto' 'dhcp'
To have the led matching DRG A226M features, using the internal editor vi edit the /etc/config/system file. Add:
config 'led' option 'sysfs' 'power:red' option 'trigger' 'heartbeat' config 'led' option name lan option 'sysfs' 'usr1:red' option trigger netdev option 'dev' 'eth1.0' option mode 'rx tx' config 'led' option name wan option 'sysfs' 'usr2:red' option trigger netdev option 'dev' 'eth1.1' option mode 'rx tx'
The OpenWrt firmware don't provide by default webui. just telnet interface. To configure the modem through the web interface you should install WebUI (like Luci). To do that you can follow the instructions
opkg update opkg install luci
opkg update opkg install kmod-rt61-pci
Reboot system to activate WiFi.

A226m has a Le88266 VoIP chip onboard providing 2x FXS ports (= 2x ports you can connect analog phones to in order to make calls leveraging VoIP). This functionality is not natively available in OpenWrt, it requires additional drivers. There is an opensource project, called bcm63xx-phone https://github.com/pgid69/bcm63xx-phone, providing these drivers, and I managed to compile and make it work on this router in combination with Asterisk, tested on both Attitude Adjustment and Barrier Breaker. The developer of the driver directly tested it on a Huawei box, but it also works on A226M. There is no ipk package available at the moment, so you need to compile your own .ipk's package or include them in the image of openwrt. Once you do this, you will be able to connect an analog phone to the FXS ports and leverage it in combination with a cheap VoIP service provider.
If you choose to compile the .ipk's and try to install them on a ready-available openwrt image form repository, be aware that opkg might complain about kernel version not being exaclty the same. Just force installation and it should work. I was able to make phone calls originating from an analog phone connected to the A226M and routed to a VoIP provider using SIP signalling and Asterisk as call manager.
