I have Graphics Master running CE 3. I have been able to get it to boot from Flash card with an image of CE 4.1. However when I set it to closed box upgrade, I see the amber light for a second or so then white screen. I can always go back to booting from flash card, but seem unable to complete sealed box upgrade. Using 1.79 rom. One additional note when booting from flash card after failed sealed upgrade I always get the calibration screen.
When upgrading your CE image, you often need to use new ADSLOAD.HWT and ADSLOAD.REG configuration files, which are downloadable from the Image Selector page where the images are. To determine what is happening during boot, monitor the debug port of the device with HyperTerminal. If it still fails to boot, email us your HWT and REG files, a capture of the debug output, and the ADS build number you are trying to load.
