AM62A7: Modifying DTS of Uboot and Kernel in Yocto Project

Jack

Part Number: AM62A7

Hi AM62A Champ

Can you please let us know how to modify DTS files of Uboot and Kernel side in Yocto Project?

Several customers are checking the proper usage between the board-support package of the Linux SDK and the Yocto SDK, and I understand that the sdk document link, which had recently been guided for Top-Level Makefile, has disappeared from the Index, so please introduce the correct Development Roadmap.

Thanks.

Regards,

Jack

if you want to customize the Linux Kernel and U-Boot in the context of Yocto, the below E2E post shows one way how to do that: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1303384/sk-am62-using-custom-kernel-in-local-workspace-for-yocto-ti-sdk/4953153#4953153 It has helped several customers already do that successfully.

I'm not sure what you mean with top-level makefile in the context of customizing the Yocto build. Yocto doesn't use a top-level makefile. There is a top-level makefile however that is part of the installed Linux SDK, but this is usually only used during initial evaluation of the product to introduce some quick changes and to serve as an example how to build components manually, but is not involved into building filesystem images which is what most people need as they progress with their development from the initial evaluation stages.
