Adding nrf_drv_clock_lfclk_request(NULL); seems to have solved a lot of my problems

Hi Einar,

This test was very helpful.

It seems my issue lies with the app_timer. The button IRQ is firing, but the debounce timer that app_button uses is not working. I think it has something to do with the fact that the DFU code uses a scheduler

Hi,

This should work. I did a quick example now based on the <SDK17.1.0>\examples\dfu\open_bootloader\pca10056_usb_debug\ses\.

The changes from the default project is this in main.c:

devzone.nordicsemi.com/.../0513.main.c.diff

and this in sdk_config.h:

devzone.nordicsemi.com/.../0525.sdk_5F00_config.h.diff

If you test that with a nRF52840 DK and press button 1 (0 in code), you will see a line printed.
