8 Future Work

This minimal configuration was developed for the AM62x using concepts that apply more broadly to other TI SoCs and even other Arm® processors running U-Boot and/or Linux. The configuration specifically can be extended to other devices in the K3 family (AM64x, AM67x, and so forth). It is recommended to use this minimal configuration as an example to build similar devicetrees for other SoCs. The following steps can serve as a general approach to creating a minimal configuration.

  1. Create minimal devicetrees for U-Boot and the Linux Kernel
    k3-{SOC}-minimal.dts k3-{SOC}-r5-minimal.dts k3-{SOC}-minimal-u-boot.dtsi
  2. Create minimal configuration fragments to incorporate minimal devicetrees
