However, it does support a "sample" board for educational and testing purposes. This "sample" board hosts USART & 16 bit timer devices and it's enought to run FreeRTOS based applicaton (like this @url{https://github.com/seharris/qemu-avr-tests/blob/master/free-rtos/Demo/AVR_ATMega2560_GCC/demo.elf,,demo}) The "sample" board has been replaced by the boards that Philippe added, hasn't it?
