Hi !
In Keil os_tsk_create_user() doc it passes a void* for the stack parameter, but in the example (and example code in uVision) we do the following :
static U64 stk2[400/8]; ... os_tsk_create_user (task2, 1, &stk2, sizeof(stk2)); ...
If I am right typeof &stk2 is U64 **. As the test work I think the definition is wrong.
