Linux on Spike RISC-V ISA simulator
===================================
This configuration provides a minimal working setup to run a Linux
kernel in the Spike RISC-V ISA simulator.
The Spike ISA simulator can be an interresting alternative to Qemu, in
some specific cases. For example: simulating new instructions (see [1]),
simulating riscv-openocd/gdb debug sessions (see [2], [3]), or
generating an accurate per-instruction log of execution (see
riscv-isa-sim spike -l option)...
To run Buildroot Linux in Spike, use the commands:
make spike_riscv64_defconfig
make
./board/spike/riscv64/start.sh
The boot is made with the standard RISC-V OpenSBI boot loader. In
order to keep the simulation simple, the rootfs is passed as an initrd
ramfs.
