We recently bought the Zoom SDK board with the LH7A404 on it, and I'm having trouble booting the CE image (from the zip file called LH7A404_DEV_IMAGE_For_All_Other_PNs.zip). I can load the image into RAM ok, but when I start CE using the exec command I get the debug info on the terminal, then it just hangs and my display never comes up. I found in the FAQ that one cause of this could be no CF card, and I do have one (it's what I load the image into RAM from) but I discovered that it seems to be read only, so my suspicion is that the HIVE registry is unable to be written to it. It is a 32MB Kingston, formatted with FAT16. Does my analysis seem correct, and if so, how do I get the thing to be read/write? It is obviously writeable when plugged into my card reader on XP. Thanks for your help.

Hi johna, How have you determined that it's read only? Do you have any other CF cards in your office that you can try using? Thanks,

I tried deleting and copying files on the CF card (from the losh prompt) and I can't modify anything. The LogicLoader version is 2.0.6. Is the CF card supposed to be mounted read write by LoLo? I don't have any other cards I can try at the moment, but I may go pick one up.

Hello, Writing to the CF card will not work in LogicLoader because CF is enabled as read only. If you're able to mount your CF card in LoLo I'm thinking that it might not be the CF card that's the problem. Can you please provide your LogicLoader output from the time you power on your kit to launching your Windows CE image? Thanks,

Posted By aaronlpd on 31 Dec 1969 6:0 PM Hello, Writing to the CF card will not work in LogicLoader because CF is enabled as read only. Ah, that's good to know. Thanks for the help, by the way. Posted By aaronlpd on 31 Dec 1969 6:0 PM If you''re able to mount your CF card in LoLo I''m thinking that it might not be the CF card that''s the problem. The card is already mounted when the board boots. Is that normal? All of the instructions I found mentioned mounting the CF, but I can't because it's already there. I didn't think it was a big deal, and it probably isn't. Posted By aaronlpd on 31 Dec 1969 6:0 PM Can you please provide your LogicLoader output from the time you power on your kit to launching your Windows CE image? It is pasted below. I have tried many variations on the "disp_num" parameter with identical results. My display doesn't so much as flicker. I am able to display bitmaps with the video-open and bitmap commands. (I created a new video mode called "wsharp" which is exactly what I need, can I put that in my disp_num parameter or does that have to be a number?) *************************************************************** LogicLoader (c) Copyright 2002-2005, Logic Product Development, Inc.

Hello, What display kit are you using ( or not using it would seem )? Is this a custom display? Are you able to use the 'draw-test' command in LogicLoader ? Also if you have it I'd connect a USB function cable to connect over Activesync to verify that the display is indeed the issue. Thanks,

We're using a 7" widescreen display from Sharp. I can use both the draw-test and bitmap commands successfully. However, I did that by setting up a custom video profile (called "wsharp") that is 800x480 and has the correct timing values. Display "#2" was used as the basis for this mode (the 12.1" SVGA setting) and if I use that mode without tweaks the display is mostly readable but flickers. Our vendor figured out what timings to write out (using the w command) to make it work. I have to admit I'm brand new to dealing with CE in any way, so there is probably a lot I don't know (and possibly something very dumb that I'm doing), but from the documentation it seemed it would be straightforward to get the sample CE image up and running. I just tried plugging in a USB cable and while Windows reecognized an unknown USB device, ActiveSync didn't recognize it.

One other thing: our touch interface is not connected (the wires are just hanging from the display)... could that cause CE to hang?

Good news, I got it (mostly) working. I reformatted my CF card on a Windows 2000 machine, and can now boot up. Thanks for all of your help. I may be posting again if I can't get my display working 100%. (I'm close, but have some things to try).

The issue was likely this: Windows CE was booting correctly, but these images rely on using a 'Hive' registry on the CF card. Because the card was not formatted in a way that CE could read from it, CE was failing when trying to use the hive registry on the card, which is one of the first things that it will be doing.
