我们自研的JAGX Orin主板在做高温的时候出现了掉盘问题；我们在PCIE C7上使用了一个PCIE转SATA控制器出来两路SATA，ATA1是外挂2.5寸盘，ATA2是板载的，高温试验过程中外挂盘有PCIE报错，最后的现象是外挂盘找不到了，日志看到PCIE C7上的两个SATA都SATA link down，后面换了一家外挂SATA盘后，高温试验没有出现掉盘现象，我们现在想知道如何排查来锁定问题，麻烦帮忙看下！

The provided context appears to be related to the Jetson AGX Orin Developer Kit, which consists of a P3701 System on Module (SOM) connected to a P3737 carrier board. The SOM and carrier board each have an EEPROM where the board ID is saved.
The question seems to be asking about the Jetson AGX Orin’s compatibility with SATA and PCIe interfaces.
According to the context, the Jetson AGX Orin supports PCIe Endpoint Mode, which suggests that it can function as a PCIe endpoint device. However, there is no explicit information about SATA support.
In the context of the Jetson AGX Orin’s hardware configuration, it is mentioned that the SOM can be used without any software configuration modifications. Additionally, the SOM that is sold to be incorporated with customer products has a Thermal Transfer Plate (TTP) that is ready to accept a customer-provided thermal solution.
Regarding the power modes, the context mentions that nvpmodel introduces different power modes on the Jetson platforms, which determine the CPU cores used and the maximum frequency of the CPU and GPU.
In terms of compatibility, the context provides a table with compatible property values for different Jetson platforms, including the Jetson AGX Orin. The compatible property values for the Jetson AGX Orin are listed as nvidia,p3737-0000+p3701-0000, nvidia,p3737-0000+p3701-0004, and nvidia,p3737-0000+p3701-0005.
To obtain the correct compatible string for a Jetson platform, users can enter a command, which is not specified in the provided context.
In summary, while the context does not explicitly mention SATA support, it does provide information about the Jetson AGX Orin’s PCIe Endpoint Mode and compatibility with different power modes. The compatible property values for the Jetson AGX Orin are also listed, which can be used to determine the correct compatible string for a Jetson platform.
To answer the question more comprehensively, it would be helpful to know more about the specific requirements and constraints of the Jetson AGX Orin’s SATA and PCIe interfaces. However, based on the provided context, it appears that the Jetson AGX Orin supports PCIe Endpoint Mode and has specific compatible property values that can be used to determine the correct compatible string for a Jetson platform.

What is the temperature that is in use to do this test?
I saw AER error in the log. Might need to use PCIe analyzer for the trace.
实验条件：70℃保温6小时 然后升温到85℃保温10分钟；因为我们只做了整机中的GPU模块，背板和SATA都不是我们做的，就是现在换个盘就没复现问题了，我们现在要确定是我们主板有问题还是哪个地方有问题
