Ｉwant to use the “dd” command to write the kernel or device tree into the corresponding emmc partition, when using the flashtool burning process, it is found that the boot.img and dtb files are not the most primitive boot.img and files. Therefore, I would like to ask how to generate signed boot.img and dtb files, can be copied directly through the dd command to the corresponding partition and can be boot success!
Moreover, I also use the dd command to copy all the data in the dtb partition to compare with the dtb file and find that the first 4 bytes are the generated header, then the specific dtb data, and the subsequent redundant space is filled with 0!
How to get the real boot.img and dtb files of the corresponding final burning to the partition without using the flashtool tool for offline burning!
When I intercepted a log, that burned the kernel and found that the file that was eventually written to the kernel partition was "1_ boot_sigheader.img.encrypt ", I couldn’t get the file? ? The following
