Assertions problem in nrfx driver

[control]

Hi,

I do not understand why assertion is not thrown when nrfx_saadc_init method is called with NULL event handler.  For example: 

err_code = nrf_drv_saadc_init(&default_config, NULL);

This just happen in the program with the Softdevice. If I use the template without the Softdevice the assertion is thrown. Is it possible that the template with Softdevice does not throw assertion by default?

Hi, 

Which SDK are you using? Could you compile with debug mode and provide the debug log?

I got this assertion if the software without softdevice is used. This assertion is expected because the event handler is null. I am wondering why I do not get the same assertion in my other program where I have the same code together with softdevice.

 <error> app: ASSERTION FAILED at C:\Users\Samo\Documents\nRF52_SDK\modules\nrfx\drivers\src\nrfx_saadc.c:215

Is it NRFX_ASSERT(p_config);?

If so, do you check the pin configuration?

No. The following assertion is thrown

NRFX_ASSERT(event_handler)

As I mentioned, it is expected that this assertion is thrown. I do not understand why it does not happen in another program with softdevice, where I use the same function.

err_code = nrf_drv_saadc_init(&default_config, NULL);

Is it possible that some optimization is enabled in the template softdevice project?

Maybe. You should debug to see what value is the event_handler there and why it is not NULL.
