Sparkfun LED Matrix + backpack firmware update

Hi,

I'm trying to update the firmware on the backback to reap the benefits of the new firmware. Specifically https://github.com/fornellas/SFRGBLEDMatrix

I'm using a mac I have generated the hex file I have uploaded the ISP sketch to the arduino I have a cap between the ground and reset on the Arduino Uno I have connected the ISCP pins to the target board then I run the following command: avrdude -P /dev/tty.usbmodemfd121 -b 19200 -c avrisp -p m328p -v -e -U flash:w:RGB_Backpack_vFPO.hex

and I get the following results: avrdude: Version 5.11.1, compiled on Feb 16 2012 at 22:11:20 Copyright (c) 2000-2005 Brian Dean, http://www.bdmicro.com/ Copyright (c) 2007-2009 Joerg Wunsch

avrdude: stk500_recv(): programmer is not responding

The lights on the board blink and the target board is also powered.

Any advice on how to get this firmware across?!

I’ve got avrdude saying this now:

Programmer Type : STK500
Description : Atmel AVR ISP
Hardware Version: 2
Firmware Version: 1.18
Topcard : Unknown
Vtarget : 0.0 V
Varef : 0.0 V

SCK period : 0.1 us

avrdude: AVR device initialized and ready to accept instructions

avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.

Still need help folks!
