Hi,
I try to create the separate partition as dual bootload and dual rootfs and some partition for also need the factory.
By manually partition separation is done by the cmdline inside the device terminal shell it was working good, but I need to implement in the yocto build to affect .wks in the wic tool at the build instead of the toradex default rootfs and bootfs are creating while I update the json, image tdx append file not affecting at the build tar.
only the toradex default rootfs and bootfs are created at the build succes, Instead of I need my custom partiton need to affect in the emmc at the SD card has the OS booting time and at the build the tar folder needs my custion partition in after the build success.

I need the help and suggestion to build the custom partition through the yocto build and while boot the device it need to create with the custom partition instead of the default toradex rootfs and bootfs.
