Dear Sir TUNDRA,
I am trying to jtag a cable Box CPU STi7100 with Flash ST M28W640FST to get the dump.bin. It is a Top boot 8x2000 and 127x10000 flash chip. My primary aim is to get the BoxKey from this dump.
As the box's Flash chip is FULLY covered by epoxy resin, the best method is jtagging the STB. The above value was extracted by drilling and scraping the very hard epoxy carefully to get a view of the Flash chip. Jtag pinout are correct:
19 - Trst
17 - unknown
15 - Tdo
13 - Tdi
11 - Tck
9 - Tms
7 - unknown
5 - unknown
3 - unknown
1 - unknowm
2 to 20 - GND
I have lifted the CPU and trace the track that the above is correct.
There is also a 4 pin port for DEBUG in the box, any useful procedures required for this extended port?

I dont know how to correctly edit a Test file - T3800HD (name created by me) for this box.
Also I am an OLDMAN Newbie, my progress may not be as fast as youngsters, please bear with me.
Thank you.

I think if you detect first and then read you might get better data. The CPU is DCU3 JTAG and so far NT does not support the write. Read is fine.

Thank you.

I am interested in this target after DCU3 support. I will search to find one of Sti7100 target to play with.
