Building for other targets typically requires additional programs and tools. Additionally, some targets may have a unique build process, meaning the instructions here will not apply to them. Please see the page for the specific target you want to build for before following these instructions, which can be found under the Hardware Documentation section of the Main Page.

Once you have a working compiler:

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 of the firmware you want to modify in the chipwhisperer/hardware/vicitims/firmware to a new folder. The folder you copy will depend on what tutorial you're doing. Typically, the firmware you want to use is listed above the "Building for ..." drop down menus. The name is arbitrary, but for this example, we'll call it simpleserial-base-lab1 (though depending on what firmware and tutorial you're working off of, you may want to call it something different). You must keep it in the same directory, as it will reference other files within that directory for the build process.

2. 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

3. Then, run make to build the system. Make sure you specify which platform you're using as your target. You can see a list of supported targets by typing make PLATFORM=. You'll also need to specify a CRYPTO_TARGET. Most targets and tutorials work with TINYAES128C, so if you're unsure, this is usually a reliable option. For example, for the NXP Kinetis K24F target, run:

   make PLATFORM=CW308_K24F CRYPTO_TARGET=TINYAES128C

   Which should have the following output:
