By setting CONFIG_SYS_CLOCK_TICKS_PER_SEC to 1024 instead of 1000, I have resolved the issue. It has a slight time drift but within an acceptable range.

Hi.

I'm not really sure here, I'll have to discuss this internally with someone that has more experience on this.

Will get back to you as soon as I have some information to share.

Br,
Joakim

Inserting a 4-byte elapsed time (divided down to microseconds) is also an idea, but we are dealing with clock drift.

start_time = k_uptime_get_32();
...
elapsed = k_uptime_get() - start_time;
