Prerequisites
The installation guide assumes basic knowledge of the UNIX command line (opening a shell, entering commands, navigating file system, and editing text files). Those new to command line may want to read our UNIX guide for a quick introduction and check out the unix videos and reference material prepared for CS107 students.
Overview
You must configure your laptop with an environment suitable for developing programs to run on the Mango Pi. These development tools are unix-based. Mac OS and Linux natively support an appropriate environment, on Windows you will enable WSL (Windows Subsystem for Linux) and work in an Ubuntu instance running on top of Windows OS. If you're running Windows, make sure you've already done that with the WSL setup guide.
- Install
riscv64-unknown-elfcross-compile toolchain. A cross-compiler is a development toolchain that runs on one system (e.g., x86) and generates machine code for a different system (in this case, RISC-V). The toolchain includes the C compiler and other essential development tools (assembler, linker, debugger, and utilities). - Install
xfel, our communication client for sending binaries to the Mango Pi (for Mac, this step is actually rolled into the toolchain installation, as you'll see in the steps).
Follow the installation instructions for your OS
Final check steps
After completing the installation instructions, use these final check steps below to confirm your developer tools.
Check: confirm cross-compile debug with simulator
$ riscv64-unknown-elf-gdb
GNU gdb (GDB) 13.2
... blah blah blah ...
(gdb) target sim
Connected to the simulator.
(gdb) quit
Check: confirm xfel
$ xfel
xfel(v1.3.2) - https://github.com/xboot/xfel
usage:
xfel version - Show chip version
xfel hexdump <address> <length> - Dumps memory region in hex
xfel dump <address> <length> - Binary memory dump to stdout
... blah blah blah ...
