Johnson, If you hold down the "q" key when you boot, LoLo will skip the boot time script. You can view the script with the cat /dev/config command. You can then erase the script by using the config CREATE command - or if you want to preserve it for whoever put it in there, you can simply change the first character to a blank space with echo "" /dev/config This will disable the script. Thanks Richard

Richard, I posted all of the messages transfered from Lite to Teraterm, it seems Windows CE Ethernet Loader controls the kit instead of LoLo. After I press anykey when boot, the menu show: Microsoft Windows CE Ethernet Bootloader Common Library Version 1.1 Built Sep 22 2006 10:23:42 Copyright 2006 Logic Product Development, Inc.

Thanks.

Looks like you replaced LoLo with eboot. Once you overwrite LoLo in flash there's not a lot of options. JTAG may be the easiest. Logic uses the Abatron BDI2000 but there are others.

Johnson@ultra-view.net, Did you burn e-boot into the kit, or did it come that way? If it came that way - I've real suspicions about it. A very long time ago some alpha hardware went out to our distribution partners configured like that for demonstration purposes only. If this kit happens to be on loan to you from your favorite distribution FAE, you need to realize that it should not be used for any development whatsoever. That hardware is ancient, as is the code. Is that the case? If so, you'll need to get a real, production kit. Regards, --mikee

Thanks mikee, This kit is loaned from Freescale Shanghai, China, for DEMO. So if this kit is only for demo purpose, what can I do more on this kit? Can I evaluate WINCE on this kit?

Yeah, I think you will need a released kit. That alpha hardware won't likely run any new software and you are probably setting yourself up for trouble by trying to do actual development with it. --mikee
