HRM FreeRTOS example clarification

[acanidio]

Good evening,

I'm analyzing the FreeRTOS HRM example for PCA10040.

I'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 before system initialisation
    // The best solution is to start the OS before any other initalisation.

Could you give me a hint?

I'm trying to understand if it recommented that the system will never experience any interrupt before
vTaskStartScheduler or if it shouldn't just attempt any "access" to the SD below.

Best regards,

Andrea

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.

So in short, no new limitation to be concerned about in this context.
