Change HDMI output resolution

Other Parts Discussed in Thread: DM3730, OMAP3530

Hi.

I'm using c6a816x EVM with linux kernel 2.6.34, EZSDK 5.00.00.56 and PSP 4.00.00.07. Matrix GUI application and QT examples work fine.

 

I need to change resolution to that which is not in the list of "change_resolution" script, for example 1280x1024. How can i do this?

Command "fbset" is only cut visible part of display . Also I tried to add following options to my bootargs: "omapdss.def_disp=dvi omapfb.mode=dvi:1280x1024-16", but it didn't work too.

 

P.S. Sorry for my english.

 

 Thanks.

    I don't think this resolution is supported and only the resolutions present in the change_resolution.sh script have been tested.

    Note that these bootargs look like they are from a OMAP3530 or a DM3730 or a Beagleboard. Its unlikely to have any effect on the C6A816x EVM as there is no DVI output.

    Also, there's a newer version of the EZSDK available from http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html

    Thank you for response. Does a new version of the SDK support this resolution?

    I'm afraid not. I don't think we have plans for adding it for now.
