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.
You must configure your laptop with an environment suitable for developing programs to run on the Raspberry 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.
arm-none-eabicross-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, ARM). The toolchain includes the C compiler and other essential development tools (assembler, linker, debugger, and utilities).
- Install python3, package prerequisites, and CP2102 console driver needed by the bootloader client
- Create a
cs107e_homedirectory to store your class materials
- Configure shell and git environment
Follow the installation instructions for your OS
Final check steps
After completing the installation instructions, use these final check steps below to confirm your environment from top to bottom.
Check: confirm $CS107E, cross-compile build and debugger with simulator
$ cd $CS107E/sample_build $ make clean && make all rm -f *.o *.bin *.elf *.list *~ arm-none-eabi-gcc ... blah blah blah ... $ arm-none-eabi-gdb hello.elf GNU gdb (GDB) 9.2 ... blah blah blah ... (gdb) target sim Connected to the simulator. (gdb) quit $ make
Check: confirm rpi-run.py version 2.0
$ rpi-run.py -h usage: rpi-run.py [-h] [-d device] [-v] [-p | -s] [file] This script sends a binary file to the Raspberry Pi bootloader. Version 2.0
Check: confirm CP2102 driver
If you have your CP2012 USB-serial breakout board, plug it into a USB port on your computer and confirm it can be found.
$ rpi-run.py Found serial device: /dev/ttyS3
The reported device name can vary, e.g.
/dev/cu.SLAB_USBtoUART and others.
