Flash & Debug
|
|
=============
|
|
|
|
An external debugger is required, so the procedure to flash/debug depends on the chosen interface. Using an ST-Link V2
|
|
you can flash using OpenOCD with::
|
|
|
|
openocd -f interface/stlink-v2.cfg -f target/nrf52.cfg -c "program nuttx/nuttx.bin 0x0000000 verify reset; shutdown"
