Hello all !
I'm currently trying to make a scan with our custom board, I've made a custom board with our GPIO and the use of the SPI4 instead of QSPI for the 7002 -> 5340 communication, we also use the CDC ACM USB to use direct USB connection for debug and terminal print / command.
In the scan project we have the main.c, in this main there is no indication of how the device is powered up (supply / IOVDD / BUCK EN), if I'm understanding correctly we are setting those up in the device three with the overlay / board configuration file :
/dts-v1/;

};For now I can build and program my board but I see that the power supply, io vdd and bucken is not enable, do we need to enable this on our side ? Or the device three with device 7002 on SPI4 with the given pin make this automatic, like in the pictures bellow :
There is also the board yml files, we add our two chips we use on board as in the 7002 DK board on the NCS :
board:

vendor: ROOMZ

- name: nrf5340

- name: ns
cpucluster: cpuapp
