Issue flashing Jetpack 6.2

Hello,

I am getting a timeout error trying to flash jetpack 6.2. I have twice cycled back to flashing 5.1.5 to make sure the cable hasn’t broken or something and flashing 5.1.5 works fine as always but 6.2 has failed twice with the same error. The full log is here which includes all the commands run etc. The host is Ubuntu 20.04 LTS and I have never encountered this error flashing all jetpacks <6.0.

failed_jp6_flash.txt (59.1 KB)

the specific error is

[ 9.4033 ] Sending bct_br
[ 9.4036 ] ERROR: might be timeout in USB write.
Error: Return value 3
Command tegrarcm_v2 --new_session --chip 0x23 0 --uid --download bct_br br_bct_BR.bct --download mb1 mb1_t234_prod_aligned_sigheader.bin.encrypt --download psc_bl1 psc_bl1_t234_prod_aligned_sigheader.bin.encrypt --download bct_mb1 mb1_bct_MB1_sigheader.bct.encrypt
Failed flashing generic.

Browsing the forums I was only able to find posts that linked to the FAQs here. I tried disabling autosuspend as suggested but it did not help.

Cheers

Based on the provided context, it appears that you are experiencing a timeout error while trying to flash JetPack 6.2 on your Jetson AGX Orin device. You have tried flashing JetPack 5.1.5 twice, which worked fine, but flashing JetPack 6.2 has failed twice with the same error.

The specific error message is not provided in the question, but based on the log file you mentioned (failedjp6flash.txt), I assume it’s related to a timeout issue.

After browsing the forums, you found a suggestion to disable autosuspend, but it didn’t help resolve the issue.

To troubleshoot this issue, I would recommend the following steps:

  1. Check the cable and connection: Although you’ve already tried flashing JetPack 5.1.5 successfully, it’s still possible that there’s an issue with the cable or connection. Try using a different cable or checking the connection to ensure it’s secure.
  2. Verify the host system: Ensure that your host system (Ubuntu 20.04 LTS) is configured correctly and that there are no issues with the USB ports or drivers.
  3. Check the device tree: Verify that the device tree is correctly configured for your Jetson AGX Orin device. You can check the device tree by running the command dtc -I fs /sys/firmware/devicetree.
  4. Try a different flashing method: Instead of using the SDK Manager, try flashing the device using the flash.sh script provided in the JetPack 6.2 package. This script can be found in the Linux_for_Tegra directory.
  5. Check for firmware issues: It’s possible that there’s an issue with the firmware on your Jetson AGX Orin device. Try updating the firmware to the latest version using the flash.sh script.
  6. Consult the NVIDIA forums: If none of the above steps resolve the issue, I recommend consulting the NVIDIA forums, where you can find more detailed troubleshooting guides and potentially connect with other users who have experienced similar issues.

In comparison to other issues mentioned in the context, your issue seems to be related to a timeout error during the flashing process, which is different from the other issues mentioned, such as:

  • OSError:[Errno 121] Remote I/O error on Jetson Orin Nano
  • Detectnet_v2 training failure using TAO Toolkit on DeepStream
  • Errors during Detectnet_v2 inference on DeepStream
  • Rin Nano 8GB Developer Kit - Realtek PHY MAC Address Change Causes Boot Issue
  • Jetson tx2 nx wakeup issue
  • Nvbufsurftransform_copy.cpp failed in mem copy issue

These issues seem to be unrelated to your specific problem, and I would recommend focusing on troubleshooting the flashing process and timeout error specifically.

Hi,

How do you flash your device?

Do you use the sdk manager or the manual cli to flash?

Is your host a native or a virtual machine?

Is your AGX orin a dev kit or a custom board?

Thanks

Hi @DavidDDD

In the log is all the flashing commands used. I directly use the BSP sources and the provided flashing scripts. It is flashing from an Ubuntu 20.04 host as I mentioned above. And the target device is a Jetson Orgin AGX Devkit.

Cheers

Hi,

If you use bsp source, please make sure

  1. download bsp source and rootfs
  2. Follow the official doc to setup
$ tar xf ${L4T_RELEASE_PACKAGE}
$ sudo tar xpf ${SAMPLE_FS_PACKAGE} -C Linux_for_Tegra/rootfs/
$ cd Linux_for_Tegra/
$ sudo ./tools/l4t_flash_prerequisites.sh
$ sudo ./apply_binaries.sh

Please try below commands as official doc suggestion

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

Also record the serial console log as below doc show:

Thanks

Two things you probably have already done.

disable autosuspend for usb devices on host.

echo -1 | sudo tee /sys/module/usbcore/parameters/autosuspend

do you want rootfs a/b ?

rootfs/flash_jetson_ALL_sdmmc_partition_qspi.sh 
if [[ "${ROOTFS_AB}" == 1 && "${ROOTFS_ENC}" == "" ]]; then
        EMMC_CFG=flash_t234_qspi_sdmmc_rootfs_ab.xml;

@DavidDDD This is what all of my setup processes boil down to. The only things I do additionally is change the kernel image and preinstall some debian packages into the rootfs via chroot. Here is a log of the flashing process; the first output is that of the prerequisites script, and the binaries have already been applied to the roots, although I can’t see this particular step being important for the actual flashing.

@whitesscott I have indeed tried to disable the auto suspend, but it didn’t make a difference unfortunately.

As for a/b I know that the Jetson by default has it enabled, so far I really have no preference for it, maybe in the future but at the moment it is not something I explicitly need enabled which is why I have been using flash_t234_qspi_sdmmc.xml
