FULL tutorial for flashing Espruino into nRF52832 with Raspberry Pi (Zero) using OpenOCD and SWD (two wires)
I tried to follow this tutorial but without success.
So, I'm suspicous about my soldered wires.
To test at least power wires, I was wondering if I only connect 3v3 and GND pins of my raspberry pi
3 B+ to the nRF52832 chip, I guess it should be visible from my smarphone using a BLE app (like nRF Toolbox). Could you confirm? (because currently I don't see it...)
Thank you for details and advices.
I checked my wires and they're well soldered. I'll keep investigating... (probably try an another Pi or chip)
