Hi All,

I have a question that i remark this code run different mode have different results

in Release  mode => build success,the project can run

in Debug mode => the debug terminal show : <error> app: ASSERTION FAILED at C:\Users\kai\Desktop\Git\BLE_nRF52832_1710\integration\nrfx\legacy\nrf_drv_clock.c:246

Attachment is my program, please help me to debug

If you build with Debug (not Release) you should be able to get the exact error code that is returned from nrf_drv_clock_init(). I suspect it is returning NRF_ERROR_MODULE_ALREADY_INITIALIZED, which can be ignored.

By default in Release mode all asserts are ignored.

Hi Kenneth,

I can not search NRF_ERROR_MODULE_ALREADY_INITIALIZED in my project, but in the image, the code of high light reture m_clock_cb.module_initialized is false.

If you don't call nrf_drv_clock_init(), then all calls to nrf_drv_clock...() will assert due to not initialized. However, you will not see this assert if you are buildling with Release, since the assert is not checked for Release build.
