What command are you running? From the output, it looks like you might be trying to debug the bootloader, which is probably not what you want to do. When you post output, could you please include the exact commands that you execute? The standard command sequence is: 1. Build boot loader (newt build <boot-loader-target>) 2. Upload boot loader to board (newt load <boot-loader-target>) 3. Build / load / debug main application (newt run <main-target>) Thanks, Chris
