Newbie asks:
I want to run an App onWindows XPe, where both are stored on a flash device
that has a hardware write protect switch. The App allows you to download and
execute a second app which will also be stored in the same flash device.
Neither app makes any changes to the run time image. My questions are:
1) Is EWF or FBWF required? Could the OS boot and run from the flash device
if the hardware write protect is enabled without using EWF?
2) Does EWF or FBWF need to be built into the XPe kernel, or is it an some
sort of APP that rides on top? I will not be building the OS portion myself -
it is being supplied by another party. Will they need to include EWF and the
API functions as part of the kernel using TargetDesigner? Or can I add it
later as the app programmer?
3) In order to save the second app to the flash, I would have to first
disable the hardware write protect, then do a EWF commit of the downloaded
file. Is this correct? What happens if I do a commit and the hardware write
protect is still enabled?
4) I assume that I will need to use EWF Ram Reg mode?
Thanks.
