datetime lib: Page fault error

[mglettig]

I observe issues when trying to use the datetime lib on the board qemu_x86.

I get the following page fault:

[00:00:27.920,000] <err> os: Page fault at address 0x393a24 (error code 0x11)
[00:00:27.920,000] <err> os: Access violation: supervisor thread not allowed to execute

[00:00:27.920,000] <err> os: Halting system

This is reproducible and happens shorty after successfully calling date_time_update_async.

Can you help me to narrow down the root-cause of this issue?

Setup:

- NRF SDK v1.6.0

- Compiler: zephyr-sdk-0.12.4

I also tested NRF SDK v1.7.0 RC1 and I also tested with a newer version of the compiler suite (which also comes with newer QEMU). The results were the same.

Kind regards,

Michael

Hi again,

Is your project based on a sample?

Could you please share your project's .conf file(s)?

Best regards,
