CW303 XMEGA Target/Compiling
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:
cdto the project directory with the firmware source (.c) and makefile, and run
cd c:\chipwhisperer\hardware\victims\firmware\<project dir> make PLATFORM=CW303 CRYPTO_TARGET=AVRCRYPTOLIB
where the <> part is changed to the project name.
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.
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.
