I’m very sorry to announce but Sadly, Our schematic design was wrong. About HDMI DDC Line, we inverted CLK and DAT wrongly. [20230807_HDMI_DDC_PINMUX] Correct connection. HDMI_SCL DP2_AUX_CH_P I2C6_CLK HDMI_SDA DP2_AUX_CH_N I2C6_DAT Our Wrong connection in #37. [20230807_HDMI_DDC_CUSTOMBoa…

I don’t think there would be some situation rel-35.3.1 cannot work but rel-35.1 can work. I hope so, but there are difference that rel-35.1 allows HDMI Output in UEFI, while rel-35-3.1 does not. Again, we changed only EEPROM, PINMUX, CONF, and DTB with the new rel35.3.1 Linux_for_Tegra, same as …

DCE firmware is display-t234-dce.bin in your Linux_for_Tegra/bootloader path. This is not open source and that is why there is not much to able to check. The source code you are referring to is the host side part driver which is interact with DCE.

Compare your hardware design with p3509 devkit HDMI circuit. Thank you for your suggestion. we also check hardware design too. We checked the circuit wiring and it was the same as p3509 devkit HDMI as shown below. [20230727_HDMI_SCH] The only difference between our CustomBoard and other boar…

Hi, Try to do the full flash after you modify the DT (also bootloader dtb needs to get updated too). That is the only thing I can tell for now. I will check if this is something that really can get configured or not.

Set GPIO_ACTIVE_LOW in R35.3.1 and full flash, But HPD was not enabled by the driver. ・Board Config 202307271521_jetson-agx-orin-devkit.conf (3.7 KB) p3701.conf.common (9.2 KB) ・DTB Changes tegra234-dcb-p3701-0000-a02-p3737-0000-a01-hdmi-4-ga5.0.2.dtsi (26.8 KB) tegra234-p3701-0004-p3737-0000…

I want to confirm about pinmux spreadsheet behavior. When I change following HDMI_DP2_* pin settings to HDMI, Output DTB File [Orin-jetson_agx_orin-pinmux.dtsi] didn’t change anything. A51 HDMI_DP2_TX2_P HDMI0_TXDP2 A50 HDMI_DP2_TX2_N HDMI0_TXDN2 B51 HDMI_DP2_TX1_P HDMI0_TXDP1 B52 HDMI_DP2_TX1_N …

Yes, those things are not getting changed.

Hi, Is there any way to directly output at fixed resolution without looking at the HPD status? Just for HDMI Lane testing. I want to clalify problems are Lane connection or not.

We have inserted the log all functions of [sources/tegra/kernel-src/nv-kernel-display-driver/NVIDIA-kernel-module-source-TempVersion/kernel-open/nvidia/nv-gpio.c] and updated nvidia.ko in custom board . However, no logs were output to dmesg. Thus, the nv-gpio API does not appear to be used by DCE…

We reversed the HPD logic on the circuit side, but still HPD was not recognized by driver.
We checked both GPIO_ACTIVE_HIGH and LOW in dtb.
