Restore elf image from a u-boot image

Restore elf image from a u-boot image

 

Assume your u-boot image is something like cuImage.bamboo, the architecture is PowerPC, and it’s not a u-boot multi-image (which is a bit more complex to restore); and we could restore the symbols in the following step:

 

dd if=cuImage.bamboo of=zImage bs=64 skip=1

gzip –dc zImage > Image

powerpc-unknown-linux-gnu-objcopy -v -I binary -O elf32-powerpc -B PowerPC --rename-section .data=.text --readonly-text Image Image.elf

 

You could then use objdump to check the generated Image.elf:

 

powerpc-unknown-linux-gnu-objdump –D Image.elf
