1 Get the arduino code from On unbunto get the avr compilers and downloaders apt-get install gdb-avr avrdude avr-libc Using the AVRISP mkii under linux You need to set the permission for the usb to be rw (from The fix for this was to create a new file /etc/udev/rules.d/99-avrispmkii.rules with the following line: BUS=="usb", ACTION=="add", SYSFS{product}=="AVRISP mkii", MODE="0666", SYMLINK+="avrdev" 1 / 11

2 After a udev restart and re-plugging the ISP, the device node was world writable and the Arduino IDE could do its magic. Copy The Makefile from arduino-0022/example_makefile/arduino_makefile_test/makefile Change: PORT = usb Add to AVRDUDE_FLAGS AVRDUDE_FLAGS = -p$(mcu) -P$(AVRDUDE_PORT) -c avrispmkii -B 1.0 AVRDUDE = $(INSTALL_DIR)/hardware/tools/avrdude or AVRDUDE = avrdude Sample Makefile and project for the atmega / 11

3 Building using Makefile fails because undefined reference 'to cxa_pure_virtual' Need to add to the main.cpp extern "C" void cxa_pure_virtual(void) For Arduino Change make file PORT = /dev/ttyusb0 For Wirinig the chip: 10K to from REST to VCC 3 / 11

This allowed the check to be read correctly Also: C:AVR>avrdude -p attiny13 -P usb -c usbtiny -tuf avrdude: initialization failed, rc=-1 avrdude: AVR device initialized and ready to accept instructions Reading ################################################## 100% 0.00s avrdude: Device signature = 0x / 11
