We did below change in Orin NX and HDMI is working but we do not have an option in AGX Orin, can you specify what dtb and pinmux needs to be used if HDMI to be enabled?
here in AGX Orin we used flash script with config file as below:
sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1
Edited the below mentioned file:
/Linux_for_Tegra/jetson-orin-nano-devkit.conf
Change PINMUX_CONFIG,PMC_CONFIG,DTB_FILE
Change below lines
DEFAULT_EMC_FUSE=“0”;
PINMUX_CONFIG=“tegra234-mb1-bct-pinmux-p3767-dp-a03.dtsi”;
PMC_CONFIG=“tegra234-mb1-bct-padvoltage-p3767-dp-a03.dtsi”;
BPFDTB_FILE=“tegra234-bpmp-3767-0000-a02-3509-a02.dtb”;
DTB_FILE=“tegra234-p3767-0000-p3768-0000-a0.dtb”;
TBCDTB_FILE=“${DTB_FILE}”;
EMMC_CFG=“flash_t234_qspi_sd.xml”;
to
DEFAULT_EMC_FUSE=“0”;
PINMUX_CONFIG=“tegra234-mb1-bct-pinmux-p3767-hdmi-a03.dtsi”;
PMC_CONFIG=“tegra234-mb1-bct-padvoltage-p3767-hdmi-a03.dtsi”;
BPFDTB_FILE=“tegra234-bpmp-3767-0000-a02-3509-a02.dtb”;
DTB_FILE=“tegra234-p3767-0000-p3509-a02.dtb”;
TBCDTB_FILE=“${DTB_FILE}”;
EMMC_CFG=“flash_t234_qspi_sd.xml”;
After the changes are done and saved, Flash the board.
