Firmware header looks like this:

Using this as a guide: http://www.midnightcode.org/papers/OpenWRT%20on%20the%20Belkin%20F5D7230-4.pdf   00: 16 81 01 00 - belkin magic

04: 00 10 66 00 - length. size of whole file including magic (i.e. ls -la) 0x661000

08: CRC32 from 0xC (32bit LE inverted) Doesn't seem to match...

0C: 00 00 01 00 - Version 0x100000 (1.0?)

10: 1C 00 00 00 - offset of some sort to next section?

14: 0C 80 18 00 - = 0x18800C - where mtdblock2 starts (around 6.5M - rootfs)

18: 00 00 00 00 - ?

1C: 5D 00 00 01 - = 0x100005D

20: 00 10 AF 3F - 

24: 00 00 00 00 -

28: 00 00 00 1C - 

2C: 02 AD F5 3C


One way is using the Broadcom CFE (accessed via the internal serial port 115200 baud, and pressing SPACE when directed).

The default ip address can be overriden, e.g.

ifconfig eth0 -addr=192.168.2.243 -mask=255.255.255.0 -gw=192.168.2.1 -dns=192.168.2.1

Then at f6d6230-4v1000_ww_1.00.19.bin can be uploaded via the web console:

http://192.168.2.243 (from the example above).
