If the development kernel supplied is incompatible, you may need to update the dtb partition if present, or vendor or system partition with associated kernel modules. The bootloader can either make space by moving any data following it or abandoning the operation with an error. To do this, it determines the start location of the existing kernel image in eMMC and copies to that location, keeping in mind that the new kernel image may be larger than the existing one. Kernel: The virtual kernel partition overwrites only the kernel (zImage, zImage-dtb, Image.gz-dtb) by writing the new image over the old one. In order to flash the kernel directly without flashing a new boot partition, a virtual partition can be used:
