HDMI or DisplayPort configuration

[ztm]

Hi，

I used the flash cmd and the HDMI output good on a HDMI carrier board.
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --showlogs --network usb0 jetson-orin-nano-devkit internal

From other topic, I notice board name jetson-orin-nano-devkit is for DisplayPort, not work HDMI. So I’m confused . Can anyone explain? Thanks！
