change default fdt file imx8 in u-boot

[Ahelion]

Hello all, how do I change which .dtb file is the default one in yocto build for imx8qm?

i need the imx8qm-mek-rpmsg.dtb file to be default when I build.

Br,

Hello,

To use the "imx8qm-mek-rpmsg.dtb" as default dtb you need to specify your dtb name in "u-boot-imx/include/configs/imx8qm_mek.h" file.

Below the #define CONFIG_EXTRA_ENV_SETTINGS, there is fdt_file variable defined. Assign your mentioned dtb to that variable.

fdt_file=imx8qm-mek-rpmsg.dtb\0

Best regards.
