|- |UBOOT_DTBS||
imx-boot images for the i.MX8M family contain a fit image with one ore more U-Boot device tree files. Currently, signed imx-boot images can only contain a single device tree file. Therefore, an imx-boot image will be created, signed, and deployed for each UBOOT_DTBS entry.
Signed imx-boot images use the following naming convention:
- More then one device tree: -<IMXBOOT_TARGET>-<Device Tree>
- Single device tree: -<IMXBOOT_TARGET>
Only modify the default value of UBOOT_DTBS if you have added a new device tree to the U-Boot source code. |- |UBOOT_DTB_DEFAULT|| When UBOOT_DTBS contains more then one device tree (and therefore multiple imx-boot images are deployed), UBOOT_DTB_DEFAULT is used to select the default imx-boot for the SD card image.
The default configuration is:
UBOOT_DTB_DEFAULT ?= "" UBOOT_DTB_DEFAULTmx8mm ?= "-imx8mm-var-som-symphony" UBOOT_DTB_DEFAULTmx8mp ?= "-imx8mp-var-som-symphony"
