Q: I get a USB timeout error during flash Orin. How to resolve that?
A known issue for ubuntu 20.04 host is the USB autosuspend function is enabled on it by default. This leads to Jetson recovery mode gets suspended before flash. To bypass this error, need to:
- Disable autosuspend on host PC with below command:
sudo -s
echo -1 > /sys/module/usbcore/parameters/autosuspend
- Plug out the USB cable, put jetson back into recovery mode again and plug the usb cable back.
If USB timeout is still there after above commands, please file a topic to forum and let moderator help check.

Q: How to remove the texts printed in UEFI logo?
Those texts are from both UEFI and kernel.
Please refer to How can I remove text printing from the UEFI Logo interface? - #4 by KevinFFF for the paths
Q: There is a wait in UEFI stage. How to disable it to accelerate system booting?
Please refer to the UEFI source
edk2-nvidia/Platform/NVIDIA/NVIDIA.common.dsc.inc at main · NVIDIA/edk2-nvidia · GitHub
gEfiMdePkgTokenSpaceGuid.PcdPlatformBootTimeOut|L"Timeout"|gEfiGlobalVariableGuid|0x0|5
This 5 seconds is for user to interrupt and enter UEFI menu. It could be customized setting to 0 to disable.
Q: New boot device causes boot-order changed. How can I configure them in runtime?
User can configure New Boot Devices to the “Bottom” of the Boot Order and reconfigure the existing boot order.

Q: Is there any tips for debugging UEFI?
Please rebuild the UEFI source with the link above. After you rebuild it, there would be a debug version of binary. Please replace the old “uefi_jetson.bin” file in your BSP folder and then reflash the board. It will enable full log in UEFI.
Q: There is an error in source_sync.sh script. How to resolve it?
If you are syncing rel-35.2.1 and as below error. Then it is not fatal. Those files are not needed for Orin compilation. You could just ignore it.
→ Fatal: remote error: access denied or repository not exported: /device/hardware/nvidia/platform/t23x/prometheus-dts
Q: Flashing over USBSS.
Flashing over USBSS is not supported at present.
Q: Is the DC Jack on Xavier devkit compatible to that of Orin?
Yes, they are compatible, and some customer validated that.
Q: What is the Orin power consumption of SC7?
The CVM power at SC7 is ~300mW. The CVM+CVB total power is close to 1.1W.
Q: RTC0 or RTC1 for default RTC clock during power off?
The Orignial default RTC source is set as RTC1 (Orin_RTC), which can not keep time if power off. So a patch to set default RTC to RTC0 (PSEQ_RTC) is needed.
Q: Does MGBE lines support P/N reversal?
Yes, the 10G ethernet PHY support P/N correction automatically. To make the trace smooth, we swap P and N.
Q: What is the usage of pin MOD_TEMP_SHDN_EN_N (J62) in P3737_A04?
MOD_TEMP_SHDN_EN_N is not used on commercial module. It is for Auto/industrial module to gate buffers of temp_therm and soc_pwr_req. Suggest to short to GND to keep the messaging consistent across all modules: floating = TEMP_THERM and SOC_PWR_REQ gated, GND= un-gated.
Q: Is there a signal output can be used to indicate a SW RESET thing?
There is no explicit pin on Orin that indicates an internal SW reset has occurred. Internal SW reset does not propagate to the IO pin. One way to set an indicator is to use the internal watchdog timer and use WDT_RESET_OUTA (GP63) or WDT_RESET_OUTB (GP21) as the indicator. Both signals are available on the CVM connector.
Q: How to enable HDMI on Orin AGX if I design a custom board?
Please refer to below post to modify necessary software change in device tree and pinmux.

Q: Why thermal zone/tegrastats reports -256C?
The GPU, CV power rails might be turned off at idle by run time power management. The temperature cannot be read from GPU, CV thermal sensors when the power is off. Attempts to read a sensor with the power off will return error code -256000.

please refer to this post
Q: In UEFI, Why press F9 to Reset to Defaults will cause Auto Boot Time-out to 0s?
It’s an known issue, but it would not affect the functionality of UEFI.
Auto Boot Time-out means the timeout for waiting user’s interrupt to enter UEFI menu.
Q: Why my device enters into recovery boot after successive reboots?
It may be caused from that you run reboot command before nv-l4t-bootloader-config.service gets ready.
You could refer to https://forums.developer.nvidia.com/t/reset-timing-of-boot-retry-count/277168/7 for the logic of retry count.
Q: How to flash external storage devices with WSL2?
For flashing eMMC/SD card with flash.sh, the default setting of WSL2 will work fine.
However, if you are trying to use initrd flash to flash NVMe/USB, please refer to the following post to re-build the Linux kernel with a customized kernel config, as the default kernel of WSL2 shipped by Microsoft lacks some functionalities that are required for initrd flash to work.

Q: On Jetpack 6 release, we cannot launch 8+ decoding/encoding processes.
On JP6 the allocation of hardware resource is refined. If hardware resource is insufficient, it fail to create the process. So for running 8+ decoding/encoding tasks, please create multiple threads in single process. Some discussion in the topic:
Please use Jetpack 6.1/6.2/6.2.1, apply the patches and rebuild kernel:

Please modify the following line in /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
- /dev/root / ext4 defaults 0 1
+ /dev/root / ext4 ro,errors=remount-ro 0 1
And note that this operation cannot be reversed because it can not be modified with read-only file system.
