Install the tools needed for open-isa getting started on Linux as documented here: https://open-isa.org/get-started/

open-isa-linux-getting-started-install.sh

#!/bin/bash

# This script can be used to download and install the tools as specified on https://open-isa.org/get-started/.
# Running this scipt will result in all the tools being added as sub-folders:
# - Eclipse: ./eclipse/eclipse
# - SDK: ./vega
# - Toolchain: ./toolchain
# - Toolchain OCD: ./toolchain/openocd
# - Toolchain bin dir: ./toolchain/riscv32-unknown-elf-gcc/bin/
# - OVPsim: ./riscv-ovpsim
# These are the  modifications compared to the website:
# - Uses GNU MCU Eclipse pacakged Eclipse with the required plug-ins already installed
# - The licsense for the SDK is implicitly accepted, please review it in LICESE.txt
# - The OVP Simulator for RISC-V is included 
# - Additional tools and prerequistes may be needed, such as a make and Java

# Show commands being used and error out on unexpected situations
