Have you guys made a J-Link cable yet?
As far as custom cable, please clarify if my understanding is correct:
- The cable doesn't need power, resistors or capacitors - we need to connect 5 wires from the J-Link connector to the board (PWR_VIO, SWDIO, SWDCLK, GND, RESET) and that's it
- PWR_VIO and GND of the board can be connected to J-Link's pins 1 and 20, respectively
Solved! Go to Solution.

Yes, you will need to have this intermediary card as shown in Fig 2 so that you can connect the 20-pin debugger to the 4-pin (J10) tag3 board. There are some good pictures of this interface card on the internet...

Yeah, so the question is about the schematic on figure 2. What I wanted to clarify is if I needed to solder all of the schematic together (the pull-up resistors, capacitors, power connections, etc.) or if all of that is already in the J-Link device, and I only need to connect the 5 pins on the J-Link outlet to the board.
Also, the forum mentioned that you guys were working on a cable adapter we can buy, is that ready yet?

HI Kevin,
Thanks for following up! I think I got the answer, which is that you guys don't yet have a commercially available adapter, so we do need to put together an adapter that has the pull-up resistors and the capacitor as pointed out in the instructions for setting up J-Link. I haven't tried them yet (it will take me another couple weeks to get to that), but, based on the simplicity of the instructions, I am guessing I'll succeed
Thanks,
Filipp
