The following are the steps required to build an OM2P build environment. Fortunately openmesh.com/cloudtrax provides a networking flash tool with makes flashing new versions quite foolproof. Also the original OEM firmware can be reflashed with that tool in case of problems.
1. Install and update CentOS
2. Create openwrt user
useradd -m openwrt
3. Add password for user openwrt
4. Install any missing packages:
yum -y install minicom lrzsz gawk flex ncurses-devel subversion expect git zlib-devel gcc-c++ gmp gmp-devel unzip wget
5. Switch to the openwrt user
su -l openwrt
6. Checkout OpenWRT (trunk):
svn co svn://svn.openwrt.org/openwrt/trunk
7. Updated feeds
cd trunk ; scripts/feeds update
8. Install required feeds:
scripts/feeds install luci
9. Downloading and building the ap51-flash flashing utility
svn co http://dev.cloudtrax.com/downloads/svn/ap51-flash/trunk/ ap51-flash cd ap51-flash make
10. Make the config for the required device: make menuconfig
Target System -> Atheros AR71xx/AT7240/AR913x/AT934x Target Prifile -> OpenMesh OM2P Base system -> <*> om-watchdog LuCI -> Collections -> <*> luci Server Interfaces -> <*> luci-sgi-uhttpd
11. Start the make process and enjoy a few coffee…
For now I only have the mtd layout:
dev: size erasesize name mtd0: 00040000 00040000 "u-boot" mtd1: 00040000 00040000 "u-boot-env" mtd2: 00140000 00040000 "custom" mtd3: 00100000 00040000 "kernel" mtd4: 00600000 00040000 "rootfs" mtd5: 003c0000 00040000 "rootfs_data" mtd6: 00700000 00040000 "inactive" mtd7: 00040000 00040000 "ART"
After building your firmware your firmware will be the following:
Use the ap51-flash utility built in step 9 above and run:
./ap51-flash eth0 trunk/bin/ar71xx/openwrt-ar71xx-generic-om2p-squashfs-factory.bin
Then plugin the OM2P in eth0 and power it up.
The output of the flash tool should look like this:
[MA:C-:AD:DR:ES:S ]: type 'OM2P router' detected [MA:C-:AD:DR:ES:S ]: OM2P router: tftp client asks for 'fwupgrade.cfg', serving fwupgrade.cfg portion of: openwrt-ar71xx-generic-om2p-squashfs-factory.bin (1 blocks) ... [MA:C-:AD:DR:ES:S ]: OM2P router: tftp client asks for 'kernel', serving kernel portion of: openwrt-ar71xx-generic-om2p-squashfs-factory.bin (1993 blocks) ... [MA:C-:AD:DR:ES:S ]: OM2P router: tftp client asks for 'rootfs', serving rootfs portion of: openwrt-ar71xx-generic-om2p-squashfs-factory.bin (4609 blocks) ... [MA:C-:AD:DR:ES:S ]: OM2P router: image successfully transmitted - writing image to flash ... [MA:C-:AD:DR:ES:S ]: OM2P router: flash complete. Device ready to unplug.
In order to flash a new version of the firmware and kernel from within the device itself, you must download the following files to the device /tmp folder: OM2P:
Then ssh to the device to update and perform the following:
cd /tmp mtd -e kernel write vmlinux-om2p.uImage kernel mtd -e rootfs write root.squashfs rootfs reboot ; exit
TODO, not tested
Plug a lan cable to the left connector, telnet 192.168.1.1 and set new password. For more details follow instructions on first login. Afterwards you can use the web interface at http://192.168.1.1 for further configuration.
By default, the lan interface is mapped to eth0 and the wan interface to eth1, which works but doesn't match the labelling on the case. Switching them can easily be done in the web interface.
Pushing the button for factory reset does not switch the device to failsafe mode.
There is only one tiny button for factory reset, but it doesn't seem to be supported by OpenWrt.

Note: This will void your warranty!
1. Gently remove the front 2 rubber feet (farthest from the rear ports).
2. Remove the 2 screws.
3. Carefully lift the front of the lid (not more than about 5 mm), then slide forward (away from the rear ports).
This is a 3.3v serial port

With the ethernet jacks in front of you, the pinout should look like this:
