UDP datagram sending

Hi Peter, Thank you for your reply.

Hi Mateusz,

hard to figure out from afar. Do you have your code available on github?

mathirkub/RIOT/blob/master/sys/udp_test/udp_test.c#L267-L269


      
          * 1# server.pid = thread_create(t_stack, sizeof(t_stack), THREAD_PRIORITY_MAIN, THREAD_CREATE_STACKTEST, thread_function, NULL, "udp_test");
          * 2# server.pid = thread_create(t_stack, sizeof(t_stack), THREAD_PRIORITY_MAIN + 1, THREAD_CREATE_STACKTEST, thread_function, NULL, "udp_test");
          * 3# server.pid = thread_create(t_stack, sizeof(t_stack), THREAD_PRIORITY_MAIN - 1, THREAD_CREATE_STACKTEST | THREAD_CREATE_WOUT_YIELD, thread_function, NULL, "udp_test");

Regarding 1): I don't know how this should be related to you memory violation issue.

Regarding 2): AFAIK your thread will have the priority that you give on initialization, no matter from where it is created.

Best Peter

I have tested the same scenario (thread creation with higher priority and with THREAD_CREATE_WOUT_YIELD) in /test/xtimer_msg project. All worked fine. So this could be a specific problem with my project or it could be connected with another threads running in this specific program.

It is not caused by insufficient stack size.
