Is there any relation between RTC and BT module

vinothkumars — Sat, 15 Aug 2020 06:06:10 GMT

Dear All,

I am working on IMX8QM. I disable rtc alarm wakeup. After that Bluetooth is not working.

file: rtc-imx-sc.c

- device_init_wakeup(dev, true);
+ device_init_wakeup(dev, false);

Is there any relation between Bluetooth and RTC ?

Thanks & Regards,

Vinoth S,

Hi Vinoth

ine general rtc timing intervals may be used by bluetooth driver,

seems specific reason can be found using debugging:

Using Open Source Debugging Tools for Linux on i.MX Processors

Normal and Secure Debug for i.MX8/8X Family of Applications Processors

Best regards
