I'm migrating a WinCE SOMOMAP3530 project from the (small) 128MB SDRAM to the (large) 256MB SDRAM version. I am experiencing a display flicker when the frame refreshes. I've traced this back to a Platform.reg setting. A few comments from the file are:
; Note: Rotation should not be used with the flat frame buffer, memory/bus bandwidth may
; be exceeded by display scanning requirements causing display to flicker and/or lock up.
There is no flicker when using the small SDRAM version. There is flicker when using the larger SDRAM version. I wonder if this issue was ever resolved by later BSP release. I'm only seeing a single RevA BSP release, dating to Feb2009.
I've seen some VRFB code support but I'm not able to get this working. Is this VRFB supposed to work?
Bottom line is: How can I get the frame rotated 90', when using the "large" SOM.
Thanks for the help
