# vexriscv_mem_mapped_example
### Tools:
Use the Virtual Machine 1.5 from:

[https://random-oracles.org/risc-v/](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 and step through the code with 'c' (continue). You will see the UART output in console 1 (vexriscv sim).
