[Wiki]7.Setting up Pokitto for Hardware debugging

Wiki

PEX debugging works now. So I can talk to my (relatively) old friend again :slight_smile:

I just must connect the SWD connector to Segger in the other way round it was before (when I used on-board SWD socket). I just did not dare to try it before, because I was afraid of causing a damage. I was just expecting that it should be the same way as before (probably it depended which end I happened to cut from the SWD cable for making my own cable).

Another HW lesson for a SW guy :wink:

Below is the custom SWD-to-PEX cable I have made.

AFAIK you can’t break it by connecting wrong way around (have done it several times)

Nice cable, good job

Going to put this link here - https://www.segger.com/downloads/jlink/JLink_Windows.exe
I will 100% need it in the future and this will save a morning of googling.

Whats going on? Are you sure your cable is OK?

Sorted it, I had it set as JTAG instead of SWD :stuck_out_tongue:
