example-os

An example bare bones OS template for RISC V.

Build instructions

Install the Newlib GNU RISC V toolchain and do make to build. Do make run to run. It should print out a bunch of debug information related to OpenSBI and then a single a.

Debugging

Execute make gdb and then make run.

If you'd like to trace the execution since the beginning, uncomment the # -S at the end of the line in the makefile and run. This halts the emulator until a gdb connection is established.
