An Engine Control Unit/Module that runs on the bare-metal Raspberry Pi.

Getting Started

1. To build from source, you will need an ARM compiler.
   • If you are compiling on a Raspberry Pi, the native compiler should work.
   • If you are compiling on another machine, you will need a cross compiler. You can download the latest toolchain from the GCC ARM Embedded Project. Extract the archive to a location of your choosing and add it's bin folder to your PATH.
2. Fetch the latest code from GitHub.
   • Make a directory to clone to, e.g. mkdir ~/ecu && cd ~/ecu
   • Then git clone https://github.com/MichaelBuhler/ecu.git
3. Compile the code:
   • cd ~/ecu
   • make
4. Copy the generated kernel.img (or kernel7.img) file from the /bin folder onto the (micro)SD card.
   • If you have an existing RPi Linux installation you can test this out by replaceing it's /boot/kernel.img with your own. The /boot path is probably it's own partition on the SD card. (If your card has NOOBS, this should the partition numbered 5.)
   • If you want to run the minimum bare-metal installation, reformat your SD card with one FAT32 partition and copy kernel.img to it. You will also need two RPi firmware binaries (bootcode.bin and start.elf); you can pull the latest from GitHub. Place all files at the root of the partition.
5. Plug in the SD card and boot up your Raspberry Pi.
6. [Attach the Raspberry Pi to your car's engine.]
7. Let me know if it works or if it blows up.
