The default serial driver is the one that works best on the HiFive Unleashed board. It unfortunately does not work in spike. To get spike working, you need to enable...

It does conflict. If you enable CONFIG_HVC_RISCV_SBI, then you get the wrong console when booting on a hifive unleashed board. We care more about support for the hifive unleashed board...

This does not look related to the earlier problem. Please create new issues for new problems. You are building on a windows machine, and windows likes to put spaces in...

gdb-8.1 was released on January. The RISC-V support was added in March. So you have to use the mainline development tree to get the RISC-V support. I'm not a gdb...

freedom-u-sdk is not actively maintained. We just use it for demos. You might have better luck asking questions someplace where more people are contributing, like one of the riscv IRC...

make sim isn't supported at the moment. spike lacks the driver support necessary to run u-boot. make qemu still works. If you really need make sim, then check out the...
