Hi Adam,

Do you have any clues as to why I only get garbage printed out when I try to run one of the bootstrap programs?

I thought it might be because I need to use the generic-hosted.ld linker script packaged with arm-none-eabi, but since you said you think everything should work with arm-none-linux-gnueabi, I'm questioning my conclusion now. (I haven't gotten around to testing a build with arm-none-eabi and generic-hosted.ld yet.)

Thanks,
