Hello Thomas, I am not sure if OSD can support 1920 x 1080. If you see the constraints section of the VPBE User guide for Dm644x (http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=sprue37c&fileType=pdf ), you would see that the total bandwidth cannot exceed 25Mbps, which , with 1920x1080 would easily exceed at even lower refresh rates.
Thanks and Regards, -Manju ________________________________________ From: [email protected] [[email protected]] On Behalf Of DISTEC Kloiber Thomas [[email protected]] Sent: Thursday, November 25, 2010 10:43 PM To: [email protected] Subject: davinci vpbe: How to use 1920 x 1080 mode with osd0 on DM644X? Hi all, I'm currently using MV kernel 2.6.18 from DVSDK 2.0.0.22 on DM6443. I know, that e2e forum is the better place for this kernel version and I already posted my question there as well some days ago. I did see that there is some work going on here on davinci vpbe and may be I can find some help here. I want to use 1920 x 1080 mode for osd0 fb on DM644X. My boot args are ..... video=davincifb:osd0=1920x1080x16,8100K ... But I'm not able to use more than 960 lines. The max. mode I can select with fbset is 1920 x 960. Does anyone know the reason for this limitation? How can 1080 lines be supported? Does the git kernel have the same limitation? Thanks and best regards Thomas _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
