Issue with AGX Orin SOM Power-On

Hello Team,

We are using the AGX Orin SOM with our custom board and JetPack 5.1.3. We’re encountering an issue during power on. Although we have successfully flashed the MCU code, the VDDIN_PWR_ON_N is not turning on, and the module powers off after 100 ms.

Any guidance or support on resolving this issue would be greatly appreciated.

Hi Parashuram.Biradar,

Do you have AGX Orin devkit board to compare the difference during power on sequence?

VIN_PWR_ON is output from MCU directly. It is controlled by firmware of MCU. It has nothing about Jetson side. You may need to check the firmware setting with vendor.

Hello,

We’ve tested the power sequence on both the development kit and our custom carrier board, which have the same circuit design. The development kit successfully powers on the module and carrier board, but our custom board is not activating the VDDIN_PWR_ON_N signal, resulting in the module powering off after 100 ms.

We’re using the EFM8SB10F8G-A-QFN20 MCU and have successfully flashed the code. Could you please advise on the specific firmware settings we should check or adjust to resolve this issue?

Thank you for your assistance.

I have observed that the AGX Orin Commercial module is functioning correctly with the expected power sequence. However, when we insert the AGX Orin Industrial module, it does not boot up. Could you please advise on why the Industrial module might be facing this issue?

Could you share the detailed information about these 2 modules?
There should be a string starting from 699-XXX on the module.
