|
|
|
|
|
There is no support official support for Nordic Cortex M33 chips (nRF9160 or nRF5340).

|
-------------
|
|
|
|
|
To start the GDB servers for the application core and the network core, use these commands:
|
|
|
|
|
|
|
|
|
|
JLinkGDBServer -device nRF5340_xxAA_APP -autoconnect 1 -if SWD -speed 4000 -port 2331 -swoport 2332 -telnetport 2333
|
|
|
|
|
JLinkGDBServer -device nRF5340_xxAA_NET -autoconnect 1 -if SWD -speed 4000 -port 2334 -swoport 2335 -telnetport 2336
|
|
|
|
|
|
|
|
|
|
Then you can connect GDB to targets:
|
|
|
|
|
|
|
|
|
|
(gdb_app) target remote localhost:2331
|
|
|
|
|
(gdb_net) target remote localhost:2334

1. Unlock the Net core:
|
|
|
|
|
|
|
|
|
|
nrfjprog --recover --coprocessor CP_NETWORK
|
|
|
|
|
|
|
|
|
|
2. Unlock the App core:
|
|
|
|
|
|
|
|
|
|
nrfjprog --recover
|
|
|
|
|
|
|
|
|
|
3. Flash the Net core:
|
|
|
|
|
|
|
|
|
|
nrfjprog --coprocessor CP_NETWORK --program nuttx_net.hex --verify --chiperase
|
|
|
|
|
|
|
|
|
|
4. Flash the App core:
|
|
|
|
|
|
|
|
|
|
nrfjprog --program nuttx_app.hex --verify --chiperase
|
