SWD Debugging

by john_weeks on Sat May 23, 2020 6:44 pm

Hi,
I want to develop Rust programs on my Clue.
I would like to wire the Clue to a PARTICLE DEBUGGER and use openocd.

I see SWDIO, SWDCLK in the schematic but I don't see them identified on the board or in the any docs. I see 2 solder pads on the right side center (photo attached), maybe?

Can someone identify where SWDIO, SWDCLK is on the Clue?

Thanks.

I've done some more reading and I realize now the particle debugger will not work with the clue board. I've ordered the j-link edu mini, that should work with clue.

But I'm still not sure where to connect SWDIO, SWCLK on the clue board.

Do you know? Or can you point me to the correct doc?

Thanks.

Found it!
I was able to upload Adafruit CLUE nRF52840 Express.brd from Adafruit-CLUE-PCB repo to https://www.altium.com/viewer/
And see that the pads labeled TP1, TP2. From schematic
SWDIO is TP1
SWCLK is TP2
