Hello, I try to implement an interrupt but I get always the error message -38. What does this messages mean? And when i delete in the section... if (err > 0) {int_count++;} else { printf("interrupt_task_2 error = %i\n", err); } rt_intr_enable (&intr_desc); } ... the printf command the program hang up. In my config the XENO_OPT_NATIVE_INTR is not set. Cause this any Problem? _______________________________________________________________________ Jetzt neu!
