The Arduino used is a Arduino UNO but it's bootloader is from an Arduino DUEMILANOVE. | |||
Pick this as target when compiling a new firmware for it.. | |||
When the Arduino is plugged in it displays "Linux booting.. hang in there" | |||
Once The embedded system is up it sends a welcoming message over serial and this flushed the display. | |||
