Firmware for new 9Axial nrf52832 device stucked on booting for help

Thax @fanoush, I have tried
'BTN1' : { 'pin' : 'D9' }

and built along with 'make clean' always, but nothing changed, it stucked on LED1 (red led).
I also tried the minimal board file(without BTN1) as you mentioned before to delete the cmd as follow:

#'default_console' : "EV_SERIAL1",
# 'default_console_tx' : "D25",
#'default_console_rx' : "D26",
# 'default_console_baudrate' : "9600",
 'bootloader' : 0,

But stucked on LED1 (red led) too except the green and blue led
