QEMU microblaze serial device issue

I'm attempting to use QEMU with microblaze, but it just prints an error about the serial device and quits. Anyone have suggestions as to what this means and how to fix it?

qemu-system-microblazeel -M microblaze-fdt-plnx -m 128 -serial mon:stdio -device loader,file=/opt/Xilinx/SDK/2016.4/data/embeddedsw/lib/microblaze/mb_bootloop_le.elf -gdb tcp::1137 -dtb ./repo/my_dt/my_dts/system.dtb -display none

qemu-system-microblazeel: Can't create serial device, empty char device

 

If I just run qemu-system-microblazeel by itself, I get:
VNC server running on '127.0.0.1;5900'
qemu: fatal: fetching nop sequence
