Xavier agx Power up issue

Hi,
We are using a production SOM of xavier AGX with a custom designed carrier board. The SOM was working perfectly in the carrier board without any issue. But suddenly the SOM stopped booting up and it produces a weird hissing sound. We have checked the voltage domains of our carrier board and everything seems to be fine. Both the debug log as well as the force recovery function of the SOM is not working.
Could you please guide us regarding the possible reason for this behavior which will be useful for the debugging process.

Thanks,

hello s.dharaneshwar,

what’s the scenario here, is that due to a power shortage or something else?
BTW, could you please setup serial console via port J501 to gather bootloader logs for more details.
thanks

Hi JerryChang,

We have tested the defective SOM in our another custom designed carrier board which was in a perfect working condition (with another SOM). But the defective SOM could not turn on and we could not get any information via serial console. Similarly the force recovery mode is also not working in the defective SOM.

Thanks,
Dharaneshwar S
