You'll need to have installed the GNU Embedded Toolchain for ARM. If you haven't yet, see the Installing_ChipWhisperer guide, specifically the Installing ARM Toolchain section, for details.

Once you have a working compiler (check by typing 'arm-none-eabi-gcc' at the command line).

  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 arm-none-eabi-gcc in the path. If using Windows the sidebar on the Installing_ChipWhisperer page
  3. Change the terminal to the newly copied directory. For example:

    cd c:\chipwhisperer\hardware\victims\firmware\simpleserial-base-lab1
    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


    Which should have the following output:
