Is it just not possible for the zImages in RAM to be decoded as per the
uImages ?
If I simply use mkimage to convert the image back as a uImage ( essentially
take off the first 64 bytes ? ) then iminfo will display the kernel info
The uImage file is only 64 bytes smaller so hasn't fundamentally been
uncompressed but also offsetting the iminfo by the 64 bytes makes no odds
either
Did I miss the point somewhere?!
=> tftp 82000000 uImage
done
Bytes transferred = 7954944 (796200 hex)
=> iminfo
