AVR Dragon JTAG on Ubuntu Precise

Lt. Col. Pat Ichi Karg at Little Rock Air Show in F4 PhantomI have a BACnet Development Kit which uses the example firmware compiled from the open source BACnet Protocol Stack hosted on SourceForge.net using gcc-avr. I attempted to load the firmware onto the kit using an Atmel AVR Dragon USB JTAG programmer.  I connected the AVR Dragon to my Ubuntu Precise Linux Laptop and attached the 2×5 JTAG cable to the development kit board, and attempted to program using avrdude as I had many times over the last several years.

avrdude -c dragon_jtag -p m644p -P usb -B 8 -U hfuse:w:0x93:m -U lfuse:w:0xD7:m -U efuse:w:0xFC:m
avrdude: usb_open(): cannot read serial number "error sending control message: Operation not permitted"
avrdude: usb_open(): cannot read product name "error sending control message: Operation not permitted"
avrdude: usbdev_open(): error setting configuration 1: could not set config 1: Operation not permitted
avrdude: usbdev_open(): did not find any USB device "usb"
make: *** [writefuses] Error 1

Aha, I said, I must need to edit the UDEV rules for AVRICEas I did previously.  But alas, that did not solve the problem.  It seems the syntax for the UDEV rules have changed from using ‘SYSFS’ to using ‘ATTR’, and so the new rules use the following text in a /etc/udev/rules.d/45-atmel.rules file :

# udev rules file for atmel usb devices (for udev 0.98 version) 
# 
SUBSYSTEM!="usb_device", ACTION!="add", GOTO="avrisp_end"
# Atmel Corp.JTAG ICE mkII 
ATTR{idVendor}=="03eb", ATTR{idProduct}=="2103", MODE="660", GROUP="dialout"
# Atmel Corp. AVRISP mkII
ATTR{idVendor}=="03eb", ATTR{idProduct}=="2104", MODE="660", GROUP="dialout"
# Atmel Corp. Dragon
ATTR{idVendor}=="03eb", ATTR{idProduct}=="2107", MODE="660", GROUP="dialout"
LABEL="avrisp_end"

After saving the file, unplugging and plugging the AVR Dragon into the USB port, I was finally able to program the board.

avrdude -c dragon_jtag -p m644p -P usb -B 8 -U hfuse:w:0x93:m -U lfuse:w:0xD7:m -U efuse:w:0xFC:m

avrdude done. Thank you.

  1. Awesome! Thank you for this. I had forgotten that I’d had to set up udev rules on my prior distro. All working again.
