RTC Support - MaaxBoard

Question

Does the MaaxBoard support the Secure Real Time Clock of the i.MX8M? Is the external 32KHz osc included on the SBC?

Hi Michael,

Please clarify if this isn't want you are asking about.

Yes the board has an external 32kHz Osc RTC included on the SBC going into the BD71837MWV which drives the RTC in the SOC. See cropped snipit of schematic for reference.

Thanks,

Josh

I am not sure, But it's just a matter of the kernel configuration.

You can build the kernel with Secure Non Volatile Storage (SNVS) RTC and enable it.

Check this. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/rtc/rtc-snvs.c?h=v5.7
