Dear Andy,
In message MM1P123MB126008DA9E9DF7F8F08BB81EB2D30@MM1P123MB1260.GBRP123.PROD.OUTLOOK.COM you wrote:
Is it just not possible for the zImages in RAM to be decoded as per the uImages ?
You can decode only the information that is in there. uImage adds an extra 64 byte header with informnation I considered useful to have, like names, timestamp, checksum.
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
You confuse things here. mkimage _adds_ a 64 byte header to create the uImage file from zImage (or similar). iminfo displays this uImage header. Similar when using FIT images.
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
Wrong, uImage has 64 bytes header _added_ - and all this has nothing to do with compression at all.
Best regards,
Wolfgang Denk
