Because it seems like I have some trouble with address > translation, could it be the problem? this is an architecture specific question so you should say which target you are talking about. musl officially only supports linux userspace, but a lot of code in it should work unchanged in kernelspace or baremetal environment. but you are on your own to figure out how to make that work. not sure what trouble you have with address translation, but that's either outside the scope of the libc or part of the crt startup code that sets up the runtime environment on a baremetal system.
