I thought that the mapping of the stack happens when iterating from _start & L4_PAGEMASK to _end & L4_PAGEMASK and mapping the single pages. Before that loop, I do a read-write touch on the stack: > l4_touch_rw(thread_stack[count], sizeof(thread_stack[count])); I tried to map the stack array separately, but I failed because l4_task_map wants a l4_fpage_t object that does not fit to the type of the stack array. > Can you please clarify what you mean with the last sentence? The execution of all threads including the access on the function parameters on the stack works if I assign all threads to L4RE_THIS_TASK_CAP and do not create new tasks.
