Part Number: AM3894

Tool/software: Linux

Hi,

I am wondering if there is any patch that SDOCM00095231 issue is resolved in http://processors.wiki.ti.com/index.php/TI81XX_PSP_04.04.00.02_Release_Notes.

There is a problem that HDMI output of AM389x is blank as below. 

Is the issue regarding to SDOCM00095231?

    SDOCM00095231 issue is : "[HDVPSS-fbdev]Screen goes blank on calling fbdev ioctls in loop or under heavy load"

    I do not think the issue in the e2e thread is related to SDOCM00095231. I do not see fbdev ioctls in loop or under heavy load in this e2e thread.

    Regards,
    Pavel

    Hi Pavel,

    The problem seems to be similar and FBDEV seems to be related to VPSS FVID2.
