S32G2 load dtb

I got dts both in ATF and in kernal.When the board boots,Which dtb it will actually use?Or it will load both? Thank u.

Re: S32G2 load dtb

Hi,

Both DTB/DTS will be used. When booting, TF-A/uboot will use the TF-A DTS/DTB, when uboot passes the control to the kernel, the kernel will use its own DTB/DTS. There is no conflict between both.

Both DTB/DTS should be configured accordingly, if not when uboot passes control to the kernel, devices might not be available to the kernel itself.

Please, let us know.

Re: S32G2 load dtbSorry，I can not understand well and could you describe it more detailed.I can find the same device in DTS both in ATF and kernal. Do they conflict with each other?Re: S32G2 load dtb

Hi,

Both DTB's will be used at the end, but the one that is available under the root partition of the SD card should be the Kernel one.

Please, let us know.
