DM365 VPBE VideoWindow SDRAM address

Sebastian Kruber

Hi,

writing my VPBE kernel module I found three different register to set the SDRAM address for video window 0:

VIDWIN0OFST, VIDWINADH, VIDWIN0ADL

To which should I write the video buffer address?

Thanks in advance!

    Sebastian,

    Please refer to the VPBE programmers guide for description of each register. the address has to be set in two registers VIDWINADH and VIDWINADL which has upper and lower DDR address of the buffer where the input data is.

    VIDWINO0FST register is the register to program the line offset for the data in the DDR.
