TVE output not working

Rooney — Thu, 28 Jun 2012 17:50:40 GMT

Can anyone explain what I have to enable in the linux kernel v2.6.35.3 provided by Freescale to enable video output on TVE?

I've a i.MX53 QSB. Video is working on the VGA connector if I use the provided image on the SD card that was included in the board. I just had to change the boot params to video=mxcdi1fb:GBR24,XGA di1_primary tve

By the way, I don't use the linux kernel in combination with ltib.

I think there must be some enabled options in the kernel support TVE output on the VGA connector, but unfortunately I don't find them...

Regards,

Rooney

video=mxcdi1fb: YUV444,TV-1080P30 di1_primary tve

Looking at BSP11.09 Release Notes I found another video parameter to be used with TVE. There is a list of supported resolution as well, please take a look.

If you´ve been taking kernel from git.freescale I believe the config file has already TVE enabled by default.

What rootfs do you use? (I´m just curious, I don´t think it matter for you issue)

Hi!

That works!!! Thanks a lot!!

By the way, I'm using Debian Squeeze as rootfs, created with debootstrap.
