I am working with an imx6 digi board. I builded a system with yocto 2.4 and 4.9 version kernel.

When I build al the system, with:

=> bitbake dey-image-qt

Kernel and dtb files are packaged together in a single fil with .boot.vfat extension, and the root file system is packaged in rootfs.ext4 extension file. This worked and the system boot well, but I needed to make some changes in kernel, precisely change kernel logo, so I made the chenge and rebuild only the kernel. 

First to try if the chages works fine I mounted vfat an rootfs to boot from tftp, and replace .bin file. At fisrt the system botting well, the logo kernel is chenged, all ok, but when I  remounted vfat the system dont boot again, there is some error with kernel file (.bin).

I need help with this.
