Current time in Zephyr using ARM Qemu board

Hi,

You probably can try this PR https://github.com/zephyrproject-rtos/zephyr/pull/1502 if you want to manage system time by gettimeofday()/settimeofday(). Note that It's still under review and only works for cortex-m boards for the time being.

Hi,

I am trying to get the current time using the following:

time_t rawtime; 
struct tm *info;
time( &rawtime );
info = localtime( &rawtime );
printf("Current local time and date: %s", asctime(info));

However, this is giving me an error on Qemu:

qemu: fatal: Trying to execute code outside RAM or ROM at 0x05252ff4

Is there a reason for this? Also, is there another way to get the current time of the system in Zephyr?

Any help would be much appreciated.

Cheers,
Yie

Did you try to run your app under debugger and see what happens there?
