FRDM Device Trees for Education and Rapid Prototyping

是

To simplify development on the NXP FRDM board family, new device trees have been created for the i.MX91, i.MX93, i.MX95, and i.MX8MP platforms. These device trees are intended to provide a more ready to use out of the box experience by preconfiguring the Raspberry Pi connector with the same peripheral mapping commonly expected on Raspberry Pi compatible hardware.

With this approach, developers, students, and makers can use compatible expansion boards and HAT style accessories more easily, without needing to create or significantly modify additional device tree files. Instead of spending time on low level hardware description updates, users can start evaluating peripherals and building applications directly on top of the provided configurations.

For convenience, this post includes a .zip package containing:

The compiled device tree binaries (.dtb)
The device tree source files (.dts)
The kernel patch for the NXP Linux Kernel 6.18 required to integrate these changes

All files are attached to this post, allowing users to easily reuse, modify, or integrate the device trees into their own projects.

To configure a new device tree, compile it, and flash it onto the target, you can refer to the following guides:
