I have a simple code.
send msg to a message queue. and handle the message in another thread.
I my old environment ncs2.4.0. I looks works well.
// after get msg queue. to data.
switch (data.msgid)
{
case RECV:
case SEND:
printk("%lld get msg and prepare.\n",k_uptime_get() );
fre = (uint8_t) data.field2;
switch(fre){
case 0:
fre = 2;
break;
case 1:
fre = 20;
break;
case 2:
fre = 200;
break;
default:
(void)fre;
}
if(fre == 2){
char *info="shut down now.";
printk("%s\n", info );
}
if( STATUS_IDLE == get_sys_status() ){
printk("%lld handle.\n",k_uptime_get() );
sys_prepare();
}
else{
printk("%lld handle.\n",k_uptime_get() );
sys_prepare();
}
just simple code.
I my old environment. the time difference is less than 1ms.
but after some time. my environement damaged. and I set new environment. and copy the same code t0 run
find the time gap is as much as 15 to 20ms.
I did not modify code .
why such simple code take so long time.
