Sajiv,
Since no one has chimed in yet I thought I'd add a post to this thread. Your best bet is probably going to be be to go through Sharp's support department regarding that particular BSP.

If you're looking to just have a WinCE Platform to application development on I'd recommending using one of Logics Sample NK.BINs. These can be found under the "Sample WinCE Images" category of the all downloads page.
