| Use the executable ``qemu-system-avr`` to emulate a AVR 8 bit based machine. |
| These can have one of the following cores: avr1, avr2, avr25, avr3, avr31, |
| avr35, avr4, avr5, avr51, avr6, avrtiny, xmega2, xmega3, xmega4, xmega5, |
| As for now it supports few Arduino boards for educational and testing purposes. |
| These boards use a ATmega controller, which model is limited to USART & 16-bit |
| timer devices, enough to run FreeRTOS based applications (like |

| Following are examples of possible usages, assuming demo.elf is compiled for |
| - Continuous non interrupted execution:: |
| qemu-system-avr -machine mega2560 -bios demo.elf |
| - Continuous non interrupted execution with serial output into telnet window:: |
| qemu-system-avr -M mega2560 -bios demo.elf -nographic \ |
| -serial tcp::5678,server=on,wait=off |
| and then in another shell:: |
| - Debugging with GDB debugger:: |
| qemu-system-avr -machine mega2560 -bios demo.elf -s -S |
| and then in another shell:: |
| and then within GDB shell:: |
| - Print out executed instructions (that have not been translated by the JIT |
