Hello,

I am having problems with Olimex xds100v3+ Rev.E . I must be doing something very fundamentally wrong, so lets start with wiring. How should I connect these wires and should I be specifically using a 14-pin or 20-pin "TI connector"?

Connect the dots for me so I can try it out.

What is your target chip and target board exactly? We need the schematic to be able to recommend what connector to use. Maybe if it is custom-made board share the programming connector diagram - upload the picture somewhere and give us the link to see it.

It is a custom design. I'll ask my customer if I can share more. Chip is tms320f2803x. I'll get back to you.

Meanwhile we notice that we have a board with similar chip, maybe use it as basis. This board has 14-pin TI layout JTAG connector:

Check these instructions on how we connect XDS100v3 to it:

Ok, here is as much I was permissed to share:



What do I do? What should I connect? I was able to use Elpotronic FlashPro2000 programmer via the sister connector X101, but after experimenting R148 I think I fried the board. I need to switch to another one. But like something was working becaue ELpotronic was fully working. What should I do with XDS100V3+ now?

You should use jumper wires or bread board to manually establish connection. That JTAG  X7  connector is non-standard pinout, you need to use individual wires for the JTAG connection. Standard connector can be seen:

Neither of the listed connectors have TCK on pin 2/3 - TDI on pin 6 and TMS on pin 7, etc....
