S32G399A - Is Device Tree Configuration for U-Boot required?

GuilhermeS32G3 — Wed, 04 Sep 2024 01:55:28 GMT

Dear NXP fellows,

I see, for example, that in the Release BSP41.0 of U-Boot, there is no specific DTS or DTSI files concerning the S32G399A board in https://github.com/nxp-auto-linux/u-boot/tree/release/bsp41.0-2022.04/arch/arm/dts .

The Arm-Trusted Firmware has the DTS files for the S32G boards.

However, I saw one project where the developer patched U-boot for including the configurations required by the S32G boards.

So, my question is: Are the DTS configurations in this case managed exclusively by the ATF or I do have to manage the DTS in U-Boot too?

Thanks for your help,

Best regards,

Guilherme

Thanks for the post

From BSP's perspective, the dts is managed by ATF, you may not need to modify the files under u-boot.
