Working on Ubuntu, I have built the seL4Test project for RISCV64.  I think.  At least, there were no build errors.

I have qemu-system-riscv64 installed.  But when I get to the ./simulate command, all I get is an echo of "Unsupported platform or architecture for simulation".

I configured this test as follows:

../init-build.sh -DPLATFORM=hifive -DRELEASE=FALSE -DSIMULATION=TRUE

After the 'ninja' command completes, in the images/ directory there is a 6.6MB file named sel4test-driver-image-riscv-hifive which I am guessing is the resulting image to run, though qemu is not impressed by it, saying that the image format is not specified.

Maybe I am just not finding the instructions on how to run this, or what 'simulate' WOULD have contained, had things been working as I expect.  Or the complete qemu command line to run it.
