Hi Christof, the problem is that I don’t really know what happens but it goes something like that:
calling pd_init -> pd_init_systems -> conf_init -> x_connective_setup -> pdint_setup and then in function class_new vp is empty so while (*vp) doesn’t go through it and after exiting class_new the microcontroller stops with a hard error. So maybe the question is really - should the vp be empty and if not - why is that happening?
