Hi,
I have a question about how to build the kernel image with the dtb file attached to the kernel image. I built the kernel image with the dtb file attached . But the built kernel image can’t boot after u-boot loading it to DDR memory..
Following is the procedure to build the kernel image with the dtb file attached.
1. Set Kernel Menuconfig:
Boot options —>
[*] Use appended device tree blob to zImage (EXPERIMENTAL)
2. device tree dtb file attached to the kernel image
$: cat arch/arm/boot/zImage arch/arm/boot/dts/xxx.dtb > arch/arm/boot/zImage_dtb
3. Build uImage
mkimage -A arm -O linux -C none -T kernel -a 0x80008000 -e 0x80008000 -n 'Linux uImage' -d zImage_dtb uImage_dtb
4. The log file Log_zImage is the error message for booting zImage_dtb.
The log file Log_uImage is the error message for booting uImage_dtb.
Could you help to check the problem? Thanks a lot.
