Thanks for explanations.

I learned about uImage and Uboot from these pages
http://free-electrons.com/blog/uncom...kernel-on-arm/
http://www.isysop.com/unpacking-and-...-uimage-files/

I managed to extract kernel in a gzip file but not shure the right size.
I still have to recalculate the 2 crc

What is the size of your original unzipped kernel ? (arch/arm/boot/Image ?)
What is the entry point of the kernel ? (Seems to be 70008000 from image_header)

[edit] The data content is image_header struct + one Image (Uboot code + embedded gzip kernel)
I have not seen this case in doc. Is it arm related ?

-----

As I writed previously, I would like to patch the kernel to try to setup 1Ghz CPU and SleepCover without having to recompile it.

Sooner or later, I should setup a build environnement to recompile kernel
but I'm not ready yet as I'm starting from scratch on Linux and have a lot to learn ...
