13:50 <gautaz> Hello everyone, has anyone experience with the JT 37x7/TSI boundary-scan controller? Any chance OpenOCD can use it as a debug adapter?

14:47 <PaulFertser> gautaz: hi. Is that supported by any other software?

14:47 <PaulFertser> gautaz: do you know what's inside?

14:48 <gautaz> You mean apart from the orginal windows software provided by the manufacturer? I did not found any yet :-).

14:51 <gautaz> I have pictures of what's inside: an Altera cyclone, an Altera EP1K50FC484-1N, an Altera EPM3256ATC144-7N...

14:52 <PaulFertser> gautaz: the only remotely similar thing supported by OpenOCD is Altera USB Blaster.

14:54 <gautaz> OK, is there any leads I can follow in order to perhaps understand how this box works ?

14:58 <PaulFertser> gautaz: wireshark can capture USB traffic on windows.

14:59 <PaulFertser> gautaz: and boundary-scan windows software should be able to play back SVF and it's a simple enough format so you can use a text editor and give it simple SVF commands and see what USB protocol looks like.

15:00 <PaulFertser> gautaz: you can also run windows software in a VM and capture USB on GNU/Linux host I guess.

15:00 <gautaz> Thanks @PaulFertser, I will start with that, qemu then :-)

15:11 <PaulFertser> gautaz: good luck! Basically, all you need to know is JTAG state machine diagram and then read SVF file format reference.

15:12 <PaulFertser> gautaz: to see an example of a protocol you can take a look at public j-link protocol docs.

15:19 <gautaz> Just found the docs, lots to dive in, thanks!
