Tumpa v2 ---> jtag ---> stb with sti7101

[deleted]

Hello,
Is it possible to do dump of the firmware of a set to box using a 20 pins jtag connected directly on the motherboard and the tumpa v2 ?
This is a Sagem catv model icadd 84.
Thank you

Hello !
Thanks you for the tip.
My box looks like this

Overview of the motherboard, I soldered some wires on what could be a JTAG connector.

I welded only the pines which seem to be linked with something. Here is the connector without wire. Possible jtag 20 pins ?

Possible jtag 10 pins ?

I do not have any experience with STBs/receivers.
I suggest you to try OpenOCD community:
http://openocd.org/discussion/
OpenOCD supports TUMPA and TUMPA-Lite
Thanks!

Thank you for your help, I knew openocd but in the past I was allergic to Linux

Discussion look closed but their forum is interesting.
Thank you very much.

I've installed ubuntu and the latest openocd for more compatibility.
The tumpa is recognized. Now I wait to obtain schematics from french forum.
