ALFA Network AP121
For a detailed description see hornet-ub. The Hornet UB is the baseboard of the AP121U, which is the AP121 with an USB jack.
The AP121 design is very similar to the Atheros AP121 reference design which is the base design of many routers. See AP121 tag below.

Firwmare file fixup
At least with OpenWrt Barrier Breaker, there is an issue that the tarball is build in the wrong way. The following script can be used to rebuild the firmware image. It requires the firmware file as the first parameter, and a different output filename as the second parameter. The script simply modifies the filenames in the contained tarball to end in .image
instead of _image
.
#! /bin/sh SIZE=$(stat -c%s "$1") || exit 1 tmpdir=$( mktemp -d ) tar -xzf "$1" -C "$tmpdir" ( cd "$tmpdir" for f in *_image; do mv "$f" "$( basename "$f" _image ).image" done tar -czf newfw * ) mv "$tmpdir/newfw" "$2" rm -rf "$tmpdir" dd if="$1" bs=1 skip=$(( $SIZE - 0x21 )) >>"$2"
Automated flashing with a script
You can use this shell script to flash devices that have the original firmware:
#!/bin/sh # Pass the firmware image file to be flashed as the first and only # command line argument. # # Some of the curl calls are probably not quite neccessary. The last # one uploads the firmware, if the image was OK, then a website is # returned, otherwise "Firmware file error" is thrown. fw="$1" if [ "x$fw" = "x" -o ! -f "$fw" ]; then echo "Please specify firmware file as parameter" exit 1 fi curl \ --user-agent 'Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0' \ "http://192.168.2.1/login.asp" curl \ --user-agent 'Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0' \ --referer 'http://192.168.2.1/login.asp' \ --data 'admuser=admin' --data 'admpass=admin' \ http://192.168.2.1/goform/checkSysAdm curl \ --user-agent 'Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0' \ --referer 'http://192.168.2.1/index.asp' \ "http://192.168.2.1/management.asp" curl \ --user-agent 'Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:12.0) Gecko/20100101 Firefox/12.0' \ --referer 'http://192.168.2.1/management.asp' \ -F filename=@"$fw"\;filename=firmware.img -F uploadFWButton=Upload \ "http://192.168.2.1/cgi-bin/import_settings.cgi"
