@fanoush figured out the issue. The display driver uses D9, which is an NFC pin for the nrf52832. Solution was covered in another conversation as a temporary measure, and to compile the firmware with the special tag (
'DEFINES += -DCONFIG_NFCT_PINS_AS_GPIOS',) to let the NFC tags be treated as normal GPIOs.
