https://devzone.nordicsemi.com/f/nordic-q-a/74459/hrm-freertos-example-clarificationGood evening, I&#39;m analyzing the FreeRTOS HRM example for PCA10040. I&#39;d like to understand the meaning of the following comment available in your code in order to prevent possible issues // Do not start any interrupt that uses system functions beforeen-USTelligent Community 13Tue, 27 Apr 2021 11:11:29 GMThttps://devzone.nordicsemi.com/thread/306986?ContentTypeID=1Tue, 27 Apr 2021 11:11:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa4496f1-9a64-4ef2-b7bf-a41e62d69eb1Susheel Nuguru<p>I think the comment is not needed here as any FreeRTOS developer should know that they cannot initialize any peripherals that cause the interrupt and the interrupt handler that uses the FreeRTOS API should make sure that the kernel has started.</p> <p>So in short, no new limitation to be concerned about in this context.</p><div style="clear:both;"></div>
