Using OpenOCD and GDB with nRF52832 (PineTime)
Based on the build from lupyuen/pinetime-rust-mynewt
Uses a Raspberry Pi to run OpenOCD which connects to the nRF52 with SMD
If required, GDB then runs on top of OpenOCD (OpenOCD has quite a few commands without GDB)
Start OpenOCD in a terminal window
Currently, I am using the lupyuen/pinetime-rust-mynewt script to flash the nRF52 app which then leaves OpenOCD running, wiating for connections on port 3333 & 4444
TODO - add instrutions to start OpenOCD on its own
pi@raspberrypi:~/pinetime-rust-mynewt $ openocd/bin/openocd -f scripts/nrf52-pi/swd-pi.ocd
