I am sure that fsl-ls1046a-rdb-sdk.dtb has replaced by the new file,and I used the fsl-ls1046a-rdb-sdk.dtb to boot LSDK linux, it worked without problem.
So after rebuilding the dtb file, do i need some operations to rebuild the tiny linux ? According to my understanding,the tiny linux and it's device-tree are packed to the firmware.img file, but I don't know how to change the target file.
So the problem is I can't change the target device-tree when I build the firmware.img file, or maybe I got it wrong.
Thanks
