 +=== Installation procedure for Barrier Breaker (BB) ===
 +(Thanks to **snk** for supporting and make it work) \\
 +Since the bootloader for AA is broken and there are not yet any BB-ready images, this will give you a temporary installation for BB.
 +All BB images needed for installation can be found [[http://www.wilsoft.nl/download|here]]. \\
 +This procedure uses a tftp server on your system. See the Wiki for detailed information.
 +Set the computers IP address to 192.168.1.2. This is the serverip from which the router loads the images.
 +
 +Follow the next steps for installation
 +  - Download, sx762.img, sx762-fw.bin, u-boot.bin and place them into your tftp directory. The sx762-fw.bin contains the MAC address of your WIFI. \\ Modify the bytes 22-27 (0x16-0x1b) of this file to contain your MAC address.
 +  - Download u-boot.asc and place it in your local home directory.
 +  - Set the router in UART mode and setup a serial link to your router (see below for detailed description).
 +  - Copy the file u-boot.asc from your local home directory to the router ( "cat u-boot.asc > /dev/ttyUSB0") and wait until the transfer is completed
 +  - Because this bootloader is in RAM only we need to load the bootloader into ROM <code>
 +run update-uboot-nor
 +</code>
 +  - After this is completed we can powerdown the router and remove the UART strippings. Leave the serial connection in place!
 +  - Next power up the system and interrupt the bootproces with [space].
 +  - Now we load the firmware into flash <code>
 +tftp sx762_fw.bin
 +protect off 0xb07f0000 +$filesize
 +erase 0xb07f0000 +$filesize
 +cp.b $fileaddr 0xb07f0000 $filesize
 +protect on 0xb07f0000 +$filesize
 +</code>
 +  - Load the image into flash <code>
 +tftp sx762.img
 +protect off $kernel_addr +$filesize
 +erase $kernel_addr +$filesize
 +cp.b $fileaddr $kernel_addr $filesize
 +</code>
 +  - Reboot with the command: [reset].
 +  - Enable wifi and of you go.
