I’m trying to use the latest particle debugger dongle to debug a photon app over SWD. I have the monolithic build based on 1.4.4 flashed and have followed this step-by-step tutorial but as soon as I continue after setting my first breakpoint, the connection to openocd falls over. I’m assuming this is because the photon’s system f/w is taking over pins D6 and D7; my app definitely doesn’t use these pins.
Is this supposed to work? I realize that the tutorial was written for the programming shield which uses JTAG to talk to the photon but I was hoping to make it work with SWD. @rickkas7, can you elaborate on your comment “you will likely have problems using SWD in normal operating mode (breathing cyan)” in your JTAG and SWD post??
Any tips greatly appreciated, and if this is a dead-end/unsupported path it would be helpful to know that too.
