Hi
I have a p3767+p3768 orin nx development kit. I want to enable 4K HDMI output. The flash command i used was: JetPack: 5.1.2
sudo ADDITIONAL_DTB_OVERLAY_OPT="BootOrderNvme.dtbo" ./tools/kernel_flash/l4t_initrd_flash.sh --erase-all --external-device sda1 -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
orin nano does not support 4k display
so i tried changing jetson-orin-nano.conf to the below
source "${LDK_DIR}/p3767.conf.common";
# update_flash_args_common:
update_flash_args_common()
{
local emcfuse_bin="${1}";
local emcpredefvalue="${2}"
if [ ${EMC_OPT_DISABLE_FUSE_OVERRIDE} -eq 0 ]; then
return;
fi
# EMCFUSE_VALUE can be passed by user
emc_opt_disable_fuse="${DEFAULT_EMC_FUSE}";
if [ -n "${emcpredefvalue}" ]; then
emc_opt_disable_fuse="${emcpredefvalue}";
elif [ -f "${emcfuse_bin}" ]; then
emc_opt_disable_fuse=`xxd -ps "${emcfuse_bin}" | xxd -p -r | grep "OptEmcDisable" | awk '{print $2}' | sed 's/.*\(.\)/\1/'`;
fi
echo "emc_opt_disable_fuse:(${emc_opt_disable_fuse})"

i also tried flashing p3768-0000+p3767-0000.conf
sudo ADDITIONAL_DTB_OVERLAY_OPT="BootOrderNvme.dtbo" ./tools/kernel_flash/l4t_initrd_flash.sh --erase-all --external-device sda1 -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 p3768-0000+p3767-0000 internal
but the board did not boot up completely.
i tried using the p3509-a02+p3767-0000.conf file to flash but the Orin NX fails to boot
Enter to continue boot.
