@ -2186,11 +2186,8 @@ Tested with the Nordic nRF5340-DK. This device has two cores:
1) Application core: Cortex-M33 at 128MHz, w/TrustZone, 1MB flash, 512KB RAM
2) Network core: Cortex-M33 at 64MHz, 256KB Flash and 64KB RAM
The cores communicate using the IPC peripheral.
The network core can access application core resources (flash, RAM, and peripherals) when granted permission through the application's DCNF and SPU settings. A small portion of the application core RAM is dedicated to the exchange of messages between the application and network cores.
The DK board has two virtual COM ports. Application core and Network core will each output to different VCOM ports.
The cores communicate firmware updates using shared memory hosted on application core.
