For now I only have the mtd layout:

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.
The recommended way to upgrade is via the “sysupgrade” script. Just copy the factory image (openwrt-ar71xx-generic-om2p-squashfs-factory.bin) to the /tmp folder and run:
In order to manually flash a new version of the firmware and kernel from within the device itself, you can 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
Again, the recommended way is to use the sysupgrade script.
There is a bug in LuCI which currently prevents us to upgrade via the web interface, but a fix is on it's way.
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.
The following are the steps required to build an OM2P build environment. Fortunately openmesh.com/cloudtrax provides a networking flash tool which 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 (optional)
2. Create openwrt user (optional)
useradd -m openwrt
3. Add password for user openwrt (optional)
4. Install any missing packages: (optional)
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 (optional)
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
git clone https://dev.cloudtrax.com/git/ap51-flash.git ap51-flash cd ap51-flash make
10. Make the config for the required device: make menuconfig
Target System -> Atheros AR71xx/AT7240/AR913x/AT934x Target Profile -> OpenMesh OM2P Base system -> <*> om-watchdog LuCI -> Collections -> <*> luci Server Interfaces -> <*> luci-sgi-uhttpd
11. Start the make process and enjoy a few coffee…

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:
+---+ |RXD| +---+ |TXD| +---+ |GND| +---+ |VCC| +---+ +-----+ +----+----+ +---+ |Power| |LAN1|LAN2| |Ant| +-----+ +----+----+ +---+
It is possible to add an iBeacon bluetooth low energy module to add iBeacon functionality to the OM2P, as is demonstrated Here
