How to connect to Jtag ? #24

Closed ToutUnProg closed 11 months ago

Hi,

I wanted to flash the firmware to put TockOS into the nrf52840-mdk-usb-dongle by using a JTag probe. I build a card to connect the usb jtag probe to the dongle and connect everything as it is in the attached scheme. Cable_JTAG_IDC

Is there something wrong ? can you help me please.

@ToutUnProg It's right. You can do this.

OK, I did this on a little Card. But it does not work. Is there a process to power up the JTag and the dongle that I cannot find ? IMG_20200321_095132 IMG_20200321_095139 IMG_20200321_095145
