The board alone is not enough to boot xtensa software, as the JTAG connector
capable of loading code into CPU goes on a separate daughterboard that plugs
into FMC connectors. I will check if I can share a bitstream and if it may be
somehow used with the FPGA board alone.

However you should be able to test with qemu, as it simulates all necessary
hardware. Some examples are listed here:
