Installation
------------
1. Run tftp server on your PC (IP: 192.168.2.2) and put OpenWrt initramfs
image (initramfs.bin) to the tftp root dir
2. Open the following link in the browser to enable telnet:
http://192.168.2.1/cgi-bin/telnet_ssh
3. Connect to the router (default IP: 192.168.2.1) using telnet shell
(credentials - user:admin)
4. Run the following commands in the telnet shell (this will install
OpenWrt initramfs image on nand flash):
cd /tmp
tftp -g -r initramfs.bin 192.168.2.2
mtd write initramfs.bin firmware
mtd erase firmware_backup
reboot
5. Copy OpenWrt sysupgrade image (sysupgrade.bin) to the /tmp dir of the
router
6. Connect to the router (IP: 192.168.1.1) using ssh shell and run
sysupgrade command:
sysupgrade -n /tmp/sysupgrade.bin
Return to stock
---------------
1. Copy stock firmware (stock.bin) to the /tmp dir of the router using scp
2. Run following command in the router shell:
cd /tmp
mtd write stock.bin firmware
reboot
Recovery
--------
Connect uart (pins are silkscreened on the pcb), interrupt boot process by
pressing any key, use u-boot menu to flash stock firmware image or OpenWrt
initramfs image.
