StartOS EE_rq_insert stuck in while loop

[szalokicsiga]

Hi!

In EE_oo_StartOS() my program stucks in EE_rq_insert() function in the following while loop:

p = EE_NIL;
q = EE_rq_first;
prio = EE_th_ready_prio[t];

while ((q != EE_NIL) && (prio <= EE_th_ready_prio[q])) {
p = q;
q = EE_th_next[q];
}

I couldn't find out why is it stuck.

The values are:
q=0
p=0
prio=2
EE_th_ready_prio=(2,8,128,64,32,16,4,256,1)
EE_th_next=(0,0,0,0,0,0,0,0,0)

Does anybody have any idea?
Thank you!

EE_NIL is -1

I guess you modified the default initialization of the data structures, the one you published will never work... just try...

Actually I didn't modify anything in that, so I don't understand.

th_next is used to queue tasks in the ready or stacked queue... all 0 is not a valid value! is the configuration coming out of RT-Druid initializing everything to 0? that seems really really strange!

Sorry, my bad. NVM_init accidentally wrote zeros to the memory, where is EE_th_next is stored...
Thank you for your help!

ok, good to know... what kind of project are you currently developing?

I'm just trying to integrate the OS into an existing project in a company. Just basic cyclic tasks and ISRs.
