    The kernel is reporting that the file you're running isn't a valid executable file format. For all Nios II Linux systems, each executable must be in a flat binary format. This usually entails running elf2flt on any applications that you build.

    If you'd like I can take a look at the Makefile you're using and try to figure out what's going on. If so, please pm me or post it here in the forum.

    if you run a shellscript you get the same error message.

    To run shellscripts following option must be compiled into the kernel:
