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...

Mjpeg-streamer input plugin for Icamview based IP cameras 

Today I have managed to create an input plugin for the Mjpg streamer which grabs the JPG frames from my Asus Mimic CX200 IP camera trough it's properitary protocoll.

Q: Ok but what is it good for?
A: Originally this camera was purcashed by my father for survillance purposes. But the quality of the supported softwares, made it unusable to it. The client software could only record to AVI which means the PC have to deconvert the JPG frames, and compress them to the video format. With two cameras it was a challange for his old AMD Duron config. I am going to write a survillance output plugin to the mjpg-streamer which will allows to control the input plugins and the output_file plugin configuration in a comfortable way.


I send my greetings to all developers at the Megatec for their bullshit products.
