Hi Sir

Since the HDMI on the EVB is not allow to be used, why it is there for? (I traced few usecases code and ran them. I found this. )

Please correct me if I am wrong. I just want know how I can use this HDMI port. Can it be an input port?

thanks

Hi Jack

I am not sure what was the conclusion on this thread. Which exact usecase are you trying for which the HDMI display is not coming up?

Do you see any errors on the display logs?

Also are you running the BIOS only version or the Linux + BIOS version?

Regards

Hi Piyali

Thanks for your response to this issue!

I am sure I am not the only one who has this issue. If you can help me to resolve this, it will be great.

I have tried RTOS and Linux use case but not see any HDMI shows anything yet.

I did not see any error message yet(I may miss something).

Where we want to start?

The standard SDK usecases for Cascade radar do not show anything on the HDMI. They output the data over Ethernet. Can you please highlight was usecase you are running?

Hi Piyali

I used vision sdk usecase instead of radar sdk usecase. It is TDA2SX and it directly connected to HDMI so I assume it is ok to run vision sdk usecase.

If I am wrong in some where, please correct me.

thanks

That should be fine. It would be great if you could share the precise usecase you are running.

From the hardware aspect, we have SD card and HDMI connection. And, the SD card is working while HDMI is not. I would suggest we could start from

"null_src_display" use case.

We could have some issues need to consider

1. The boot able board settings

-> we are using MMWAVE-DSP-EVM

2. The dts file setting

-> It may not have HDMI description in the dts.

-> we may need minimum set of dts to help debugging.

3. Where is the HDMI driver

--> the chip dtsi should have description for it.

--> But, why it is not working now.

Thanks
