F5D7230 JTAG Debrick

Thanks to PreacherPhil (for posting the JTAG pinout) and HairyDairyMaid (for writing the debrick for the WRT54g) I was able to make this work for the Belkin F5D7230.

My Belkin died a horrible death months ago and although I tried every possible pinout combo I couldn't find the correct JTAG pinout for the Belkin. It turns out the my VMWare image doesn't respond exactly the same as normal hardware does so the detection was screwed up. Now with the confirmed pinout I loaded DSL (Damn Small Linux) and the compiled source of HDM and it detected the Broadcom chip. After making some Belkin specific changes I was able to get a copy of the CFE from my 2nd Belkin and dump it into the dead one. And it came back to life! The attachment has the source and executable plus the HDM guide with specs for the JTAG cable.

Edit: JTAG pinout for the Belkin F5D7230 is:
3 TDO
5 TDI
7 TCK
9 TMS
