Napi facepalm: OpenOCD telnet port

Retro: ASUS mimic CX200 JTAG hacking 

Back in my university years I have had some issues with an Asus MIMIC CX200 camera. One of them got broken after a firmware upgrade so I have decided to fix it with JTAG. I have successfully got to UrJTAG to read the IDCODE of the S3C4510B, but I was unable to detect the flash. Now I know that I have had to tweak the bus driver and reveng the board a bit.

Here are some pics (shot with my Nokia 6230 in VGA res) about the trick:


Thin albanian wires were soldered directly to the pins.


Live together cry together series 100 Ohm level shifter JTAG adapter to LPT port.


I have designed an addon board to expose the CPU's intresting interfaces (2 serial, USB, JTAG)



It is fun to look back to those pictures from now. After 5 years we got to a state when it is easier and cheaper to buy a Rpi to solve the same problem rather than fixing that board...

New Freescale Codewarrior USB-TAP disassembled 

The Freeescale support was very gently, so they are provided a free replacement for my dead USB-TAP. Of course I have disassembled it to check that did they added ESD protection to the USB lines.
Yes they did:
