    Hello,

    We burn the winCE OS image in the flash of the LH7A400-10 zoom SDK.It will reload the image everytime power on or reset the device.But
    it takes about 2 minutes to image appearance.actually how much time it will take? or any other idea to reduce this boot time?

    another problem,we encountered is that our custom application for serial port which is developed using visual studio.net is located in the
    my computer of the image(any folder) using activesync3.8 is not available when power off or reset the device.Is any method to boot our custom applicaion during boot time of OS?or Is any other idea to place our application on the flash.Please give me your suggestion as early as possible.

    thanks & regards

    How large is your image?

    Is this a Flash (XIP) image or a Relocation image?

    hello,

    Thanks for u your reply.My OS image size is about 15MB.I built using release.I build using ram and also burn it into Flash and relocate_from_flash.More or less these take about 120 seconds for booting.Is it ok?

    Thanks & Regards

    Check out this document. It goes through some basic boot time quantification on the LH7A404-11, which is going to be very comparable to the LH7A400-10.

    120 Seconds seems very suspicious. Are you sure you have not created any custom code with incorrect use of 'wait' functions? Also, are you sure you have used the most up to date drivers that we have released? I would suggest comparing the drivers you are using currently with what is on our download site now.

    The best practice to figure out an issue like this is to start with a very basic image. No custom apps or drivers, just a simple image with the drivers you need. Find if this boots ok and then begin adding your custom stuff and also more components from Platform Builder.
