Modem Support
|

|
|
=============
|
||
|
|
|
||
|
|
Modem is supported in the nRF91 using Nordic's `Modem library <https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/nrf_modem/README.html>`_.

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

|
Segger J-Link
|
||
|
|
-------------
|
||
|
|
To start the GDB servers for the application core, use these commands::
|
||
|
|
|
||
|
|
JLinkGDBServer -device nRF9160 -if SWD -speed 4000 -port 2331
|
||
|
|
|
||
|
|
Then you can connect GDB to targets::
|
||
|
|
|
||
|
|
(gdb) target remote localhost:2331
