The first (and minor) problem is that you need to specify the
exact path to the kernel file: qemu will not randomly look in
/boot (why should it?) but only where you tell it to. If you
specify a filename with no directory part it will look in the
current working directory.

The more major issue here is that you seem to be trying to run
a standard Linux kernel and filesystem image on this machine.
This will never work -- the lm3s811evb is a machine based on
the ARM Cortex-M3 microcontroller, which does not have an MMU
and is not capable of running Linux.

If you want to use the lm3s811evb model you need a binary
(probably an RTOS or possibly a standalone bare-metal app)
which has been compiled specifically for this hardware.

What are you actually trying to achieve here?
