TI logo shows and not video

John Anderson

I have a decoder application I wrote for the DM368 using DVSDK 4. There is a TI logo on the screen and an orange "loader" type bar graph underneath. I've been having various problems with my decoder app, but I am (was) able to see the decoded video on the screen. Now suddenly out of nowhere the TI Logo/Bar won't go away and I can't see my video.

It flashs on the screen and then comes back. My decoder is sending frames to the display thread. And the display thread is putting them to the display, but I have no video image?

I need to know how to change that logo anyway. Can anyone point to where in the DVSDK that is controlled?

John,

Disable fbdev through menuconfig and try.

You can also disable fbdev through bootargs.

To disable fbdev through bootargs you can refer section 3.4.1.1. of DaVinci Linux VPBE Frame Buffer Driver User Guide from the following link

John,

I believe you are talking about TI boot progress bar, the boot progress uses "psplash" utilty which display the required logo. So you can either clear frame buffer memory after login or uninstall psplash utility from targetfs. See below on how to do this

1) Clear framebuffer after login

# cat /dev/zero > /dev/fb0

2) Uninstall psplash util

opkg remove psplash-ti

opkg remove psplash

HTH.

Thanks
