Running on Ubuntu 16.04.5.

On VirtualBox 5.2.18? Not on hardware. Does that make a difference?

make sim

will compile fine
but will get stuck during boot at/after

[ 0.176795] NET: Registered protocol family 17
[ 0.177780] bootconsole [early0] uses init memory and must be disabled even before the real one is ready
[ 0.178880] bootconsole [early0] disabled

latest source has this problem on my configuration Ubuntu 16.04.5 LTS amd64 4GB RAM.

complete log is at

Thanks.

The default serial driver is the one that works best on the HiFive Unleashed hardware, and it unfortunately does not work on spike. You need a patch to enable the old one. Yet another item we should add to the new README file.

Thanks Jim. I will try this and get back to you.

I am assuming you meant Freedom Unleashed Hardware. I am looking at the Freedom U540 board and its SDK.

Works fine. Thanks Jim.

I added changes to the freedom-u-sdk to add this spike serial console info, and also the build dependencies for qemu and spike.
