Original description

What steps will reproduce the problem?

1. Uploading software images to my Arduino Mega2560 with avrdude where the hex file is bigger than around 20k

What is the expected output? What do you see instead?
I get avrdude stk500v2_ReceiveMessage(): timeout

arduino 1.0, avrdude 5.11, latest dfu code, latest bootloader, I have a original Arduino Mega2560 R3.

Please provide any additional information below.
I have installed and self complied latest librxtx, avrdude, dfu-programmer, sun-6-java-jre, arsuino 1.0, I have upgraded the dfu code and bootloader with latist code from github. Took me 2 weeks to get everything done, arduino newbie! However I have 15 years of c++/java ex[erience commercially and I am a electronic hobbiest for the last 25 years! I have fiddled with avrdude.conf etc, etc.

I run ubuntu 10.04 and Win XP same problem. I can upload the same hexfile onto my Arduino UNO R3 no problem! It cannot run code as it already uses more than 2k of sram. hexfile is 20980 bytes in size.
