 RTX time manage questions about os_itv_wait ........

os_itv_set(20);
while(1) { os_itv_wait(); msdelay(100);
}

this is part of my code in one of RTX TASKS, every

time run to "os_itv_wait()", current task sometimes

can not change to another task; when os_dly_time,

i meet the the same situation; why os_itv_wait()

function can't change the current task to another ?

 RE: RTX time manage questions about os_itv_wait ........

Is there another task ready to run?

 RE: RTX time manage questions about os_itv_wait ........

YES, There is another "ready sate" task existing,

and the current task can't change to it

 RE: RTX time manage questions about os_itv_wait ........

yes, my version is MDK303a, when using

os_dly_wait(),i meet this problem, when using

os_itv_wait(),i meet this problem ,too;

so i want to know whether there is problem with

os_itv_wait() in this version;

thank you very much!

 RE: RTX time manage questions about os_itv_wait ........

When I met my problem whit os_dly_wait I sent an e-mail to technical support of Keil, and Keil sent me a library RTLRTX.lib whit the resolution of the bug.....I suggest you to follow the same way.....good luck !!
