我们自研的主板，使用的SDK是Jetpack6.2，我们使用SPI2挂载了一个FRAM，在设备树中添加了FRAM的相关内容，系统下识别不到设备，下面是相关信息的截图，麻烦帮忙看下

Based on the provided context, it appears that you are asking about the Jetson AGX Orin SDK, specifically the Jetpack 6.2 SPI2 FRAM images. However, the provided information does not directly relate to the question.
The context provided is a repetitive list of the Jetson Software Architecture and Boot Architecture, which includes various components such as Documentation, Sample Applications, Deep Learning Components, Computer Vision, Accelerated Computing, Graphics, Multimedia, Sensors, CUDA-X, Board Support Package, Developer Tools, and Other Components.
To provide a comprehensive answer, I will attempt to relate the question to the provided context.
The Jetson AGX Orin SDK is a software development kit for the Jetson AGX Orin module, which is a high-performance AI computing platform. The Jetpack 6.2 is a software package that includes the operating system, drivers, and tools for the Jetson AGX Orin module.
The SPI2 FRAM images mentioned in the question are likely related to the storage configuration of the Jetson AGX Orin module. FRAM (Ferroelectric Random Access Memory) is a type of non-volatile memory that is used in some embedded systems.
The images listed in the question (830132, 257 KB; 1261272, 30 KB; 877409, 343 KB; 901352, 948 KB; 1018179, 839 KB) appear to be a list of image files with their corresponding sizes. However, without more context, it is difficult to determine the specific purpose or function of these images.
In comparison to the provided context, the Jetson AGX Orin SDK and Jetpack 6.2 are related to the Jetson Software Architecture, which includes the Board Support Package and Developer Tools. The SPI2 FRAM images may be related to the Partition Configuration, which is part of the Boot Architecture.
To provide a more detailed answer, additional information is needed, such as the specific purpose or function of the SPI2 FRAM images, or how they relate to the Jetson AGX Orin SDK and Jetpack 6.2.

能麻烦帮忙看下吗？
Hi 2799029655,
Is your FRAM with SPI of 1V8 or 3V3 level?
spi@c260000 is SPI2 from SPE rather than SPI3 from 40-pins expansion header.
Have you configured the pinmux for SPI2 before use?
需要纠正一下，我设备树配置的就是spi@c260000 只是复制的上面spi@3230000的格式，所以显示了这一行/* SPI3 in 40 pin conn */；FRAM这颗芯片可以支持1.8V到3.3V，PINMUX中已经配置SPI2相应管脚为SPI，前面有给出PINMUX中修改的内容
请问有帮忙看嘛
Please get a scope to measure its level. As my understanding, SPI2 is from SPE, which works with 1V8 by default as there’s no level shift like the pins from 40-pins header.
Could you simply shorting SPI2_DIN and SPI2_DOUT to verify loopback test before connecting with your FRAM SPI device?
我现在将设备切到SPI3上了，测量芯片的VDD管脚电平为1.8V,系统下还是没有找到设备，我现在怀疑是设备树或者驱动配置的有问题
Please always verify SPI loopback test(before connecting to SPI device) no matter you are using SPI2 or SPI3.
Is there any error showing in dmesg?
Please share the full dmesg for further check.
问题已经解决，更换到SPI1后，pinmux不能配置z态
