Hi
The sys_reset pin was overvolted during the test. Is this signal generated by a structure other than the processor on the Som module. If so, can you tell me what components are damaged?
I found that the Sys_Reset line goes to the BT54 diode by doing pin-to-pin. There is a test point at the output of the diode. But I couldn’t find where this pin goes. During overvoltage, 24V came to the Sys_Reset pin. I assume that the BT54 diode is intact. Can you explain where the line goes?
Please refer to Jetson Orin Nano Developer Kit Carrier Board Reference Design Files https://developer.nvidia.com/downloads/assets/embedded/secure/jetson/orin_nano/docs/jetson_orin_nano_devkit_carrier_board_reference_design_files_a04_20230320.zip/
The Jetson Nano module itself was overvolted on the SYS_RESET pin in another carrier circuit. What I wonder is which integrals on the Jetson Nano Som module may have failed? Is the SYS_RESET pin directly connected to the Jetson Nano SOC?
Repairing Jetson Nano module is not recommended or supported in this forum. You could try to check if the Jetson Nano module is still functional with a known good carrier board.
I tested the Jetson Nano module on the Nvidia B01 Jetson Nano Development circuit after the failure. Unfortunately, Jetson Nano does not work. I am sure that the SOM module has failed. What can I do about this to repair the Jetson Nano SOM module?
Please get in touch with distributor from where the module was purchased. However, this type of user faults/damage may not be covered under Warranty.
Of course, these faults will not be covered by the warranty. I wonder if they have a repair document or SOM module schematic for such faults? It may be enough for me if you share this topic. Is there a direct connection between the SYS_RESET signal and the Jetson Nano SOC? As far as I have examined from other forms, you have answers that it is connected to the PMIC integration. Can you give some technical details about the subject? I wish to use my Jetson Nano SOM module.
We do not have a repairs document and do not provide the SOM schematics.
Please advise whether there is a direct connection between the SYS_RESET signal and the Jetson Nano SOC. I would be grateful if you could provide an answer to this question. I did not feel that you were very helpful.

Where is the integrated circuit you call the power subsystem located on the module?
