Packages for avrdude and required libraries for OpenWRT Barrier Breaker (14.07) on Raspberry Pi.
Place the files in the OpenWRT filesystem (e.g. with scp) and install with:
opkg install ./avrdude_5.11.1-2_brcm2708.ipk ./libncurses_5.9-1_brcm2708.ipk ./terminfo_5.9-1_brcm2708.ipk ./libusb-1.0_1.0.9-1_brcm2708.ipk ./libusb-compat_0.1.4-1_brcm2708.ipk ./libreadline_6.2-1_brcm2708.ipk ./libftdi_0.20-1_brcm2708.ipk ./librt_0.9.33.2-1_brcm2708.ipk ./libpthread_0.9.33.2-1_brcm2708.ipk
Tested on a Raspberry Pi with an Arduino Uno (using the kmod-usb-acm module for /dev/ttyACM0).
