Hello!
I have problem with binding xenomai's queue. I created queue at the kernal
space with Q_SHARED flag and binded queue at user space.
static int __init sample_module_init(void)
{
int err;
printk(KERN_DEBUG "init sample module device\n");
err=rt_queue_create(&QUEUE,"Queue_msg1",1024*20,Q_UNLIMITED,Q_SHARED|Q_DMA);
printk(KERN_DEBUG "err=%i\n",err);
return 0;
}
and it was created correctly: err=0 and at
/proc/xenomai/registry/native/queues derictory was queue's name.
but I cannot bind queue from user space.
int main() {
cl_err err;
//CIniFile ini;
int ret1,ret2,itmp=1;
msgbuff q;
char asd[50];
//mlockall(MCL_CURRENT|MCL_FUTURE);
//tasks
rt_task_create(&Cycle1, "cycle1", 0, 90, 0);
rt_task_create(&Cycle2, "cycle2", 0, 91, 0);
ret1=rt_queue_bind(&MsgQue1_2,"Queue_msg1",TM_INFINITE);
printf("ret=%d:%s",ret1,strerror(-ret1));
....
rt_queue_bind returns -12:cannot alocate memory.
I tried change flags and execute code from rt_task or from main.
Does anyone have similarly problem or know problem-solving?
xenomai version: 2.4.7
platform: blackfin bf537
os: uclinux
