John,
Thanks for generating the DS logs. On initial look, I don't see anything suspicious yet. But I should be able to analyze it further tomorrow.
Btw, my co-worker was looking into this issue as well. He was able to get his hands on a LS1227 board, and was able to load programs to it without any problems. So something in your environment might be the cause of the problem, maybe the device you are using or the program you are loading? Not sure yet.
Do you have another program you can try loading to your device to see if it works or not? Or maybe a different device to test on?
Thanks,
Ricky
