Is it possible that DFU without 32.768k crystal on custom board?https://devzone.nordicsemi.com/f/nordic-q-a/114435/is-it-possible-that-dfu-without-32-768k-crystal-on-custom-boardThanks in advanced. I want to implement OTA on sdk17.0.2 with nrf52832, but the example secure_bootloader and ble_app_buttonless_dfu are both configed with NRF_CLOCK_LF_SRC_XTAL.
