Setting of REGOUT0 in nrf52840 dongle

[stefanogradozzi]

Hi,

I erase and flash nrf52840 dongle with nrf connect, then I read the value or REGOUT0 and the result is 0xFFFFFFFC that corresponds to Vout = 3V.

I'd like to know in which part of the software structure REGOUT0 is programmed so that its value is 0xFFFFFFFC.

Thanks

Hi,

The register is configured during the initial boot by the board specific sys init function defined here: https://github.com/nrfconnect/sdk-zephyr/blob/3733e7097909ae964e60cf66e4d51ade975ddcae/boards/arm/nrf52840dongle_nrf52840/board.c#L10 

Best regards,

Vidar
