You'll need to have installed avr-gcc and avr-libc. You may have already done this by following the installation guide, or if using the ChipWhisperer-VM it comes prepared with avr-gcc already setup. See the Installing_ChipWhisperer guide for details.

Once you have a working compiler (check by typing 'avr-gcc' at the command line - if using Windows you may need to setup a special batch file to provide you with a avr-gcc command prompt).

  1. We want to use the existing SimpleSerial firmware as a base for our project, but we don't want to edit the existing firmware. Instead, we'll make a new project with a copy of this firmware. Copy the directory simpleserial-base which is found at chipwhisperer/hardware/victims/firmware/ of the chipwhisperer release to a new directory called simpleserial-base-lab1. You must keep it in the same directory, as it will reference other files within that directory for the build process.
  2. Open a terminal with avr-gcc in the path. If using Windows the sidebar on the Installing_ChipWhisperer page - you can either add WinAVR to your system path, or you can run the 'winavr.bat' file suggested.
  3. Change the terminal to the newly copied directory. For example:

    Windows:
    cd c:\chipwhisperer\hardware\victims\firmware\simpleserial-base-lab1
    Linux/macOS:
    cd chipwhisperer/hardware/victims/firmware/simpleserial-base-lab1
  4. Then, run make to build the system. Make sure you specify which platform you're using as your target. For example, for the ChipWhisperer Lite target, run

    make PLATFORM=CW303

    Which should have the following output:

  5. Ensure that the "Built for platform ___" matches your target device.
