i build the zephyr samples/hello_world Demo ,and it can run and print well on BOARD_NRF52840DK_NRF52840.
but this hex file cannot boot up on my own board.
for simplest case, my own custom board only use 4 pins (SWC SWD GND VCC) from this www.aliexpress.com/wholesale
someone suggests set BOARD_ENABLE_DCDC=n but not work for me.
so i need some help
thx!
