https://devzone.nordicsemi.com/f/nordic-q-a/73998/ncs-delay-driver-in-zephyrAt boot-up of the Zephyr kernel drivers are loaded by default. Is there a way to change this? I prefer to load the drivers depending the board configuration. I can see an option to edit the driver but this is not working for me at this moment.en-USTelligent Community 13Fri, 16 Apr 2021 08:24:13 GMThttps://devzone.nordicsemi.com/thread/305228?ContentTypeID=1Fri, 16 Apr 2021 08:24:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3eb715d3-1ccd-4a82-b739-df05ade40478Simon<p>What do you mean by &quot;kernel drivers&quot;? Simply all the drivers that are initialized by the kernel before main? E.g. for the nordic specific serial driver <a href="https://github.com/nrfconnect/sdk-zephyr/blob/v2.1.99-ncs1/drivers/serial/uart_nrfx_uarte.c">uart_nrfx_uarte.c</a>&nbsp;the <a href="https://github.com/nrfconnect/sdk-zephyr/blob/v2.4.99-ncs2/drivers/serial/uart_nrfx_uarte.c#L1732">init function specified in the DEVICE_DT_DEFINE</a>&nbsp;will get called before main,&nbsp;by the function&nbsp;<a href="https://github.com/nrfconnect/sdk-zephyr/blob/v2.4.99-ncs2/kernel/device.c#L67">z_sys_init_run_level()</a>.</p> <p>Would you like to change this?</p><div style="clear:both;"></div>
