Hi.

I want to change to DVI-output from HDMI-output.

I have been investigating on uboot, using "logo on" command.

I changed HDMI_CTRL(0x46C009BC) bit 0 to 0. But I could not output DVI.

Do you know the DVI output of sample code anyone?

Either change the register where the HDMI Peripheral?

I am using DVRRDK_02_00_00_24 with Udworks platform.

Best regards

I can help you change to DVI mode but only in Linux. Is that what you want to do?

Thank you for reply, Ralph.

No problem on linux.

I have developed a board of the DVI-output, but I could not output video from the DVI. (DM8168 -> DVI-D Connector -> Monitor)
I modified source based on DVR_RDK(02.00.00.24 @ UDWORKS) which HDMI-output.

I want to modify DVR_RDK source to DVI-output from HDMI-output.

Okay, if you're fine on Linux that's great. I haven't looked at the U-Boot source regarding graphics so can't help you I'm afraid. Hopefully someone from TI will lend a suggestion.

Hi, jun cheng

Yes, I could slove this problem.

In my case this problem was in the circuit design.

If you have a loose TPD12S521 laying around, you can check the part's continuity too, e.g. is pin 4 connected to pin 35?
