Some people have managed to use a regular 0.1" pitch 2x3 male header pressed down on the test pads to make the connections.Better would be to have a jig like this, but if you're not going to be doing this regularly then that's probably overkill. Options:Įven with this adapter, it's a bit challenging to get the pogo pins aligned with the small test pads on the Nano 33 BLE, but if you keep at it you'll get it eventually. A way to make the connections to the SWD pads on the Nano 33 BLE.These usually use a 2x5 0.05" pitch header/cable. ![]() A way to make a connection to the debug probe.I use this little open source debugger:.I'll go ahead and provide the instructions for that process in case it's needed: If you don't get the pulsing LED, then you will indeed need to flash the bootloader. That sketch would replace the OpenMV binary you flashed and you could then go back to using the board as usual, without needing to do the double reset before every upload. You should now be able to select its port in the Arduino IDE and upload any sketch you like. If you now see the LED on the board pulsing, that means the bootloader is still present. Press and release the reset button on your board quickly twice. I don't know anything about the Python OpenMV, so it may be a silly thing, but it's quick enough to try: The first thing I would check is whether the original bootloader is still there. You want to flash the standard Arduino bootloader.
