Other Parts Discussed in Thread: TLC59108

Dear Sirs,

I have got some problems with HDMI. The software tests were provided for ti_ezsdk_dm814x-evm_5_05_01_04 and self developed board.

The logs are below:

Hi,

What is the real problem. I am not getting. We are not supporting any power management for HDMI so that line doesn't seem of any use.

Hello Hardik,

Thanks for reply.

I can add some other log :

TFT monitor is in powersafe mode. I will try to connect oscilloscope to detect signals on data lines, but i think it will not give affect.

Do you know any methods to test software settings?

If you need some additional logs I will send you.

Thanks.
