Which board to support?

RISC-V emulator for qemu:

Very diffult issue, is emulator worth of trying? Traditionally !'m HW-oriented, and prefer "hard stuff" instead of emulatosrs.

But times changes, and is this worth of try now?

VSRVES01 -board is now up and running. Next I try to built RISC-V toolchain and reproduce original image.

Unfortunatelly there is no GIT repo yet, so I have to build it from scratch.

JTAG debugging bus is not implemented:

"There is no JTAG. It would make life more miserable because it works on write register, read memory and so on to debug Linux program. So print debug it is."

Ok, new place for TC-mirror found. At first working copy of GIT-repo is placed there. Let's try to compile.

Unfortunatelly it will take time, uP and tools chain are some kind of "beta-prototype".

There seems to be strong support from kernel development group for this VLSI-Solutions uP, so lets proceed....
