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).

<li>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 of the firmware you want to modify in the <code>chipwhisperer/hardware/vicitims/firmware</code> to a new folder. For example, if you want to modify the <code>simpleserial-base</code> firmware, copy the contents of the <code>simpleserial-base</code> folder to a new one. The name is arbitrary, but for this example, we'll call it <code>simpleserial-base-lab1</code>. You must keep it in the same directory, as it will reference other files within that directory for the build process.</li>

<li><p>Change the terminal to the newly copied directory. For example:</p>
