I am trying to test the NOVA+NUL microhypervisor.

I played with the test application "nul/michal/apps/tests/startstop".

So, I modified this test to try a new a new test case, by modifying the "hello" program that is

started by the "startstop" program.

I added to the Hello program the following code :

TimerHelper * timer;

timer = new TimerHelper(this);

while(1) {

Logging::printf("Hello ... \n", now);

timer->msleep(1000);

}

This simple code will print a message and suspend the Hello program for 1 second.

The problem is that when I tested this program alone, it worked perfectly

but when this same program is started by the "startstop" program using start_config(), it does not suspend

on the msleep(1000).

Is my test correct or allowed by the NOVA-NUL microhypervisor?

If it is the case, could anyone please help to debug this issue.

Many thanks in advance.

PS: this is my configuration script.
