Hi

I can only talk about "old" (vg non-MMU) uClinux because it's the one I work with.

In the nios2-linux/uClinux-dist/vendors/Altera/nios2 there is a file, romfs_list, that has inside it the nodes the system is going to put in the /dev/ dir

Serial ports ttyAL?. aren't there but ttyS? are. Try to put your ttyAL? instead of ttyS?

In "new" linux distros, udev populates /dev/ dir

Good luck
