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 : https://chdk.setepontos.com/index.php?topic=13408.0
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 ?
