Installation
Stable release
OEM installation using the TFTP method (via ramdisk)
One boots a ramdisk image and then does a normal OpenWrt sysupgrade (generic.sysupgrade)
Specific values needed for tftp
If one holds the WPS button and then (with button pressed) powers on the device (holding WPS button for 5-7 seconds)
the device will attempt to download a ramdisk image named ap.bin from a tftp server (but only using the WAN port)
at 192.168.1.10. Note that for 17.xx or 18.xx using the snapshot below will require the use of sysupgrade -F. Also note that some devices will attempt to load from 192.168.1.17 and that if the u-boot environment has been corrupted the ramdisk image will need to be named vmlinux.uImage.
| Bootloader tftp client IPv4 address | 192.168.1.1 on the WAN port |
|---|---|
| Firmware tftp image | Ramdisk from 'snapshots' (NOTE: Must renamed as ap.bin (or, if u-boot environment is corrupt, vmlinux.uImage)) |
| TFTP window start | approximately 5-7 seconds after power on |
| TFTP server required IP address | 192.168.1.10 (on some devices 192.168.1.17) |
OEM installation using the Serial method
→ Flashing from stock firmware requires Generic Flashing over the Serial Port
The correct commands for this device are:
setenv ipaddr 192.168.1.1 setenv serverip 192.168.1.234 tftpboot 0x80060000 firm.bin erase 0x9f050000 +$filesize cp.b $fileaddr 0x9f050000 $filesize bootm 0x9f050000
