Hi Fletcher,

Documentation for SOF QEMU is quite sparse or probably even non-
existent.

If you'd like to get a jump start, I'd recommend looking into the qemu-
check.sh script in the SOF repo. It has some instructions on how to
start the qemu, load the FW and check for boot success.


Thanks,
Ranjani
