NVIDIA ORIN AGX Prepare MicroSD Image

Hi,

I followed the following thread:

I would like to know how to boot from SD card with ORIN AGX

Hi. I am trying to get the SD card boot using the following but it fails with the following steps. Please tell me what is wrong. Preparation: PC：ubuntu(20.04) Jetson AGX orin Developer kit microSD card (ext4 formatted) Procedure: ・Reference page Flashing Support — Jetson Linux Developer Guide documentation (nvidia.com) DL and install SDKmanager on PC Run SDKmanager and install the target hardware image. Insert SD card into Orin Connect Orin and PC with USB cable (⑩USB Type-C port) Ho…

When I applied the same I got my emmc image broken. It didn`t boot from both emmc and sdcard.

The following output indicates that mmcblk0 was still tried to be modified instead of only mmcblk1. Can you help me to spot the issue? I would like to prepare .img file to distribute through SDCard.

Hi,

I have no idea what you are trying to do.
First, what’s the full command used?
Second, you are just trying to flash to a single SD card, which has nothing to do with creating an SD card image.

Hi @DaveYYY,

Thank you for your reply, as mentioned in my console output, I used the following command which is marked as the answer in the quoted reply.

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device mmcblk1p1 -c ./tools/kernel_flash/flash_l4t_external.xml --showlogs --network usb0 jetson-agx-orin-devkit internal

As I couldn`t find a proper document to prepare SD Card, I wanted to check this approach first to test the SDCard operation with ORIN AGX.

Thanks in advance,
Farabi

Hi,

The command given in the link will actually flash both eMMC and SD card, so it’s expected mmcblk0p1 is also involved, but I’m not sure why you are getting error here.

For validation, flash only eMMC with:

sudo ./flash.sh jetson-agx-orin-devkit internal

flash only SD card with:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device mmcblk1p1
-c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml”
–showlogs --network usb0 jetson-agx-orin-devkit internal

Also, can you please try with 35.4.1 instead of 35.3.1?

For generating SD card images, they are stated here:

Hi @DaveYYY,
The document you forwarded has a note like given below, and that is why I didn`t applied before:

**Applies to:** Jetson Xavier NX series only

I will give it a try with ORIN AGX with proper board name.

Is there a specific reason you recommended 35.4.1 instead of 35.3.1? I don`t prefer to change my environment if not crucial.

Best Regards,
Farabi

I think the workflow is the same between these two versions, so if you try again and find it working with 35.3.1, then it’s fine and please just keep it.
