TDA4VM: Display DRM Error

Hi Sathiya,

There is a reference board made by our partner for a different (but same family) of processors as TDA4VM, and they use micro HDMI: https://openbeagle.org/beagley-ai/beagley-ai/-/blob/main/BeagleY-AI_SCH.pdf?ref_type=heads. I think this schematic file would be a good reference.

For EDID specifically, I see that on your schematic, SDA and SCL lines are grounded.

Additionally, I also found this on Wikipedia:

And it looks like these grounded I2C lines are used to broadcast E-EDID information.

Regards,

Takuma

Hi Takuma Fujiwara,

I have notices that SDA and SCL are swapped, as well as pulled up externally in my design.

After correcting those, I can be able to get the resolution from monitor.

root@j721e-evm:~# kmsprint

        FB 62 1920x1080

But now I got another issue. The OS saying display is working properly. But I can't see anything in the display. I probed HSYNC, VSYNC, DE, PCLK pins. Those are giving outputs.

If I pullup the I2C again, the display can't be able to read EDID, but defaulting to some resolution which is working. So, no problem in the connector I suppose. What could be the issue?

Here is the kmsprint:

Hi Sathiya,

Could you remind me which SDK version this is? If this is not the latest, then it could be that there is some issue identified and fixed in newer versions for display not initializing.

Regards,

Takuma

Hi Takuma Fujiwara,

I am using SDK 9.2.

Anyway, I am curious to know that issue.

I also want to add that I missed Board ID EEPROM in my design. So, my default device tree is k3-j721e-common-proc-board.dtb. I made the changes in k3-j721e-common-proc-board.dts file to replicate k3-j721e-sk.dts and using it. 
And also i am not using display port and disabled in dts

Hi Sathiya,

There's not a particular issue I have in mind. I was mainly asking to see where I can start for looking into commits. I doubt the lack of EEPROM will cause display issues, but could you send the "dmesg" logs so that I can take a look at it and see if there is anything that looks out of place?

Regards,

Takuma

Hi Takuma,

Here is the dmesg log:

These two lies I can't upload in original format

Hi Takuma, 

Do I need make any driver change, menuconfig change or devicetree change for micro-HDMI??

Here is the dts change I made:

	hdmi-connector {
		compatible = "hdmi-connector";
		label = "hdmi";
-   	type = "a";
+   	type = "d";

		pinctrl-names = "default";
		pinctrl-0 = <&hdmi_hpd_pins_default>;

		ddc-i2c-bus = <&main_i2c1>;

		/* HDMI_HPD */
		hpd-gpios = <&main_gpio1 0 GPIO_ACTIVE_HIGH>;

		port {
			hdmi_connector_in: endpoint {
				remote-endpoint = <&tfp410_out>;
			};
		};
	};

&dss_ports {
	#address-cells = <1>;
	#size-cells = <0>;

-	port@0  {
-		reg = <0>;
-
-		dpi0_out: endpoint {
-			remote-endpoint = <&dp0_in>;
-		};
-	};
-
	port@1 {
		reg = <1>;

		dpi1_out: endpoint {
			remote-endpoint = <&tfp410_in>;
		};
	};
};

And also, can you confirm that TFP410 supports micro-HDMI? (as TFP is compliant to DVI Specification 1.0 and Micro-HDMI was introduced with HDMI version 1.4)

Could you make sure the configuration file includes DRM_TI_TFP410 which is mentioned in Kconfig file: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/bridge/Kconfig?h=ti-linux-6.1.y#n333

Could you create a new E2E for this for TFP410? This will route the question to the engineers that have more expertise with this part.

Takuma

Yes, it is defined as a module.

Will the tfp410 driver supports micro-HDMI connector?

Could you create a new E2E for TFP410 part number and post the link here?

Hi Sathiya,

Thanks for posting the E2E.

Hi Sathiya,

Checking in on this E2E. Were you able to resolve this, or does the issue still persist?

Assuming that the issue is still unresolved, could you try the following:

1. Run "kmsprint" and share the output
2. Run "modetest -M tidss -c" and share the output
3. Run "modetest -M tidss -s <connector_id>:<width>x<height>". The valid connector ID, width, and height can be obtained from the commend in #2.

Regards,

Takuma

Hi Takuma,

The issue is still there. Currently I am out. It will take a week or two to get back to the board. Once I get back, I will update in this thread.

Hi Sathiya,

Understood. No rush, and let us know whenever it is most convenient for you.

Regards,

Takuma
