Flashing the Device

The ATxmega-A1U Xplained Pro came with a full EDBG + CDC-ACM. The EDBG works with default avrdude tool. However, the below programmer must have at /etc/avrdude.conf file:

programmer id = "xplainedpro_pdi"; desc = "Atmel AVR XplainedPro in PDI mode"; type = "jtagice3_pdi"; connection_type = usb; usbpid = 0x2111; ;

In order to flash the ATxmega128A1U, simple run:

make BOARD=atxmega-a1u-xpro flash

Serial Terminal

The CDC-ACM will enumerate a /dev/ttyACM device.

make BOARD=atxmega-a1u-xpro term

On-Chip Debugging (OCD)

make debug
