RTC callback function cannot be triggered

SCoder41 — Wed, 05 Feb 2025 10:23:32 GMT

I am using the S32K344 chip and plan to use RTC to generate logs with timestamps and store them in the SD card, but I am unable to access callback functions.

Hi @SCoder41,

Have you set a date and time configuration for the RTC? You also need to set the interrupt driver for the RTC IRQ:

After setting a date and time, and the RTC IRQ, the RTC alarm callback should be stepped into when the alarm date&time = current date&time.

Keep in mind you do need to install the handler and enable the IRQ in the source code, as well as setting the time&date, configuring the alarm, enabling interrupt and starting the counter to enable the basic functionality of the RTC alarm.

Best regards,
Julián

Yes, I did all of these。
