Unhandled Exception in EL3 in UEFI when bootup

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin NX
1

Hi

A device encountered an abnormal crash during the UEFI phase upon reboot, causing the system to hang and requiring a power cycle to recover. What could be the potential causes? Is there a watchdog monitoring the startup process during the UEFI phase? Uploading logs.

I’m using custom board for AGX Orin. And the version of jetson linux is R36.3.

Hi hanyang369,

Can it boot before?
If so, what have you done before hitting this issue?
Is the issue specific to current device?

I would suggest using debug UEFI binary to capture detailed logs.

Hi KevinFFF,

Can it boot before?

Yes, it can bootup before. And after hit this issue, it returned to normal after being powered on again.

If so, what have you done before hitting this issue?

Nothing specific, just a normal reboot. But the temperature of the device is high.

Is the issue specific to current device?

For now it just happened once on this device.

I would suggest using debug UEFI binary to capture detailed logs.

Could you provide the steps or any references I can refer to?

Thanks

Okay, so it can be recovered through a reboot.
Do you know how to reproduce the issue? And how about the failed rate?

Will you hit the issue if temperature is normal?
