Reverse Engineering / JTAG on DIGIC chips
« on: April 22, 2018, 12:41:09 PM »
Hi !

A few days ago, I started a topic on the CHDK forum, about DIGIC 5 JTAG on a Canon S100 :

So far, I'm able to connect to the ARM, but I can't do more than peeking registers values. The camera immediately freezes, and eventually turns off.

Does anyone here has some experience with JTAG on DIGIC chips ?
