Hi,
I have flashed agx orin jp6.2.1 , devkit.
I have disabled all the boot messages and nvidia logo successfully as per nvidia documentation - UEFI Source build .
However as the above im facing the same issue.
I am still getting L4T: Attempting Direct Boot message .
I have commented this line out in L4TLauncher.c and also replaced the Boot64.efi and flashed the esp partition but for some reason that boot message still does not go.
Kindly assist

To remove the L4TLauncher “Attempting Direct Boot” message on a Jetson AGX Orin or Jetson Orin Nano device, you need to update the ESP partition. Here’s a step-by-step guide:
Jetson AGX Orin:
ls -al /dev/disk/by-partlabel | grep esp
This should output something like:
```bash
lrwxrwxrwx 1 root root 16 Sep 3 03:26 esp -> ../../nvme0n1p10
sudo mount /dev/nvme0n1p10 /mnt
3. Navigate to the mounted ESP partition:
```bash
cd /mnt/EFI/BOOT
BOOTAA64.EFI file with a new one that does not contain the L4TLauncher message. You can do this by copying a new BOOTAA64.EFI file to the /mnt/EFI/BOOT directory.Jetson Orin Nano:
The process is similar to the Jetson AGX Orin, but you need to make sure that the L4TLauncher is not included in the nvme0n1p1 partition by default.
ls -al /dev/disk/by-partlabel | grep esp
This should output something like:
```bash
lrwxrwxrwx 1 root root 16 Sep 3 03:26 esp -> ../../nvme0n1p10
sudo mount /dev/nvme0n1p10 /mnt
3. Navigate to the mounted ESP partition:
```bash
cd /mnt/EFI/BOOT
BOOTAA64.EFI file with a new one that does not contain the L4TLauncher message.Common steps:
BOOTAA64.EFI file, unmount the ESP partition:sudo umount /mnt
2. Flash the updated ESP partition:
```bash
sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1
Replace jetson-agx-orin-devkit with jetson-orin-nano-devkit if you are using a Jetson Orin Nano device.
Troubleshooting:
If you are still seeing the L4TLauncher “Attempting Direct Boot” message after updating the ESP partition, make sure that you have commented out the relevant line in the L4TLauncher.c file and rebuilt the BOOTAA64.EFI file.
Additionally, ensure that you have flashed the updated ESP partition correctly and that the changes have taken effect.
Comparison:
The process of removing the L4TLauncher “Attempting Direct Boot” message is similar for both Jetson AGX Orin and Jetson Orin Nano devices. However, the Jetson Orin Nano device requires an additional step to ensure that the L4TLauncher is not included in the nvme0n1p1 partition by default.
In summary, to remove the L4TLauncher “Attempting Direct Boot” message, you need to update the ESP partition by replacing the BOOTAA64.EFI file with a new one that does not contain the message, and then flash the updated ESP partition.

Hi @carolyuu
Whats the flash command to flash the esp partition for AGX Orin after unmounting?
I dont want to reflash the entire board right now
To update the esp partition on AGX Orin, please simply refer to the following commands.
$ ll /dev/disk/by-partlabel/esp
(if esp is on */dev/mmcblk0p10*)
$ sudo mount /dev/mmcblk0p10 /mnt
$ cd /mnt/EFI/BOOT/
(BOOTAA64.efi should be here)
thanks all, it worked.
Do you mean that you don’t need the display in your case?
If so, please try to disable the display controller from kernel device tree.
It seems another topic, please create another thread to discuss in details.
