Re: how i can determine utcb loaction in order to make thread

Now I solve that part this part of code do not work: void func(void) { printf("thread start\n"); } L4_MsgTag_t msg; L4_Clear(&msg); L4_Append(&msg,(L4_Word_t)func); L4_Append(&msg,(L4_word_t)stack); L4_Load(&msg); L4_Send(tid); when i run the program it do not display "thread start", all other debugging messages show except this. can someone please help?
