Tools:
Use the Virtual Machine 1.5 from:
https://random-oracles.org/risc-v/
Starting the Vexriscv Simulation
Open console, change to folder vexriscv and run
sbt "runMain mupq.PQVexRiscvSim"
Connecting openocd-vexriscv
Open new console, change to folder vexriscv and run
openocd-vexriscv -f vexriscvsim.cfg
Compile and run the C code
Open new console (the third one), change to folder c_project and compile the project:
make
Then load the created ELF file into the simulation via GDB:
riscv64-unknown-elf-gdb -tui -ex 'set remotetimeout 15' -ex 'target remote :3333' -ex 'load' -ex 'break main' -ex 'continue' main
Set some more breakpoints b <line> and step through the code with c (continue). You will see the UART output in console 1 (vexriscv sim).
