I am using 2.9.1 toolchain and sdk with a custom nrf5340 board and trying to use High Voltage (HV) with DC-DC mode. I don't know much about it as I have been using a nrf5340 DK for prototyping but read the documentation and am trying to figure it out.
I read this post on How to turn on nrf5340 DCDC but when I add these settings to the prj.conf:
CONFIG_BOARD_ENABLE_DCDC_APP=y CONFIG_BOARD_ENABLE_DCDC_NET=y CONFIG_BOARD_ENABLE_DCDC_HV=y
but am getting these errors:
/Users/********/Projects/GitHub/********/pcb_test/prj.conf:32: warning: attempt to assign the value 'y' to the undefined symbol BOARD_ENABLE_DCDC_APP /Users/********/Projects/GitHub/********/pcb_test/prj.conf:33: warning: attempt to assign the value 'y' to the undefined symbol BOARD_ENABLE_DCDC_NET /Users/********/Projects/GitHub/********/pcb_test/prj.conf:34: warning: attempt to assign the value 'y' to the undefined symbol BOARD_ENABLE_DCDC_HV
