I am trying to modify my app to use dual frame buffers on the LPC32XX system.   Using a single frame buffer works fine ( TFT / VGA / 24 bit).  When I attempt to switch frame buffers using the LCD_UPBASE register while "hot", the screen appears to freeze.

I suspect I need to do some other steps prior to swapping the register, but the User Manual has no guidance.

Any suggestions would be helpful.
