ncs zephyr example called 'nrfx'

[NordicSwissTom]

ncs 1.5.1, using SES, the example for zephyr
samples/boards/nrf/nrfx/src/main.c
github URL:
github.com/.../main.c

does not work for me;
while the 'button_handler' gets called OK, the LED does not toggle.

And another compiler gives a WARNING on the call lines for n
  nrfx_gppi_channel_endpoints_setup 
due types mismatch!
I think its the last argument per 
nrfx_gpiote_in_event_get(OUTPUT_PIN) 
that should be of enum nrf_gpiote_task_t, but your code is passing an 'event' kind.
I tried to fix but still no LED toggle.

Please review this example.

Thanks!

Hi!

Which board are you building for?

Best regards,

Hi Heidi, the 9160 DK (the v0.9 layout)

[Heidi]

I just tested on my nRF9160 DK (0.8.2 layout, NCS 1.5.1) and it works. Could you paste the log output from the sample when you're testing it?

I also don't see any warnings when building the code.  Could you show me the full log output when building?

Note, your toy SES compiler will not find this issue.

For the call nrfx_gppi_channel_endpoints_setup,
there is the second part defined as:
  nrf_gpiote_task_address_get( NRF_GPIOTE_Type const * p_reg, nrf_gpiote_task_t task)

but for 'task' argument, your sample source is passing an 'event' kind per:
  nrfx_gpiote_in_event_get(OUTPUT_PIN)

this gives (in a CLang based verifier)
Warning: implicit conversion
  from enumeration type 'nrf_gpiote_event_t'
  to different enumeration type 'nrf_gpiote_task_t'

When compiling with GNU 9.2.1, I do not get these warnings.
