CONFIG_BOARD_ENABLE_CPUNET

Enable nRF53 Network MCU

Type: bool

Help

This option enables releasing the Network ‘force off’ signal, which as a consequence will power up the Network MCU during system boot. Additionally, the option allocates GPIO pins that will be used by UARTE of the Network MCU. Note: GPIO pin allocation can only be configured by the secure Application MCU firmware, so when this option is used with the non-secure version of the board, the application needs to take into consideration, that the secure firmware image must already have configured GPIO allocation for the Network MCU.
