CW303 XMEGA Target/Compiling

Building firmware

The XMEGA uses AVR architecture and needs an AVR compiler. The target firmware can be found under the chipwhisperer/hardware/victims/firmware/ directory in their project (e.g. simpleserial-aes, basic-passwdcheck) folder.

• Atmel AVR-GCC standalone - see Atmel avr-gcc standalone (registration required)
• WinAVR. Last release - 2010, see WinAVR Page (no registration required)

To build the code, follow these steps:

1. cd to the project directory with the firmware source (.c) and makefile, and run make:

   cd c:\chipwhisperer\hardware\victims\firmware\<project dir>
   make PLATFORM=CW303 CRYPTO_TARGET=AVRCRYPTOLIB

   If this is successful, you'll see an output like the following:

   

   If instead you get an error something like make: *** No rule to make target `simpleserial.elf', needed by `elf'. Stop., this means a required file was missing.

2. The compiled firmware file you will use to program the target will have the format <sourcefile name>-CW303.hex, where the <> part will change based on the project.
