7 years ago You should use the script make_root.sh to compile the kernel and root filing system, as described in the Wiki.
If you want to compile manually, do not leave a space between ARCH=riscv and -j uses an integer argument which is the number of parallel jobs.
You need to compile our toolchain (an old version), also described in the Wiki, because the options have changed.
Also the verilog of the processor must be compiled first to get certain header files, before the kernel.
The v0.2 is rather old BTW.

Maybe you should modify $ TOP / riscv-tools / linux-3.14.41 / arch / riscv / Makefile. Is there a way?
For reference, on this page http://www.lowrisc.org/docs/untether-v0.2/ I ran 'Compile and install RISC-V cross-compiler' under '2. The development enviromnet' and I was following 'Compile the RISC-V Linux and the ramdisk root.bin'.
