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 ## Checking Image at 82000000 ... Legacy image found Image Name: Linux kernel Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 7954880 Bytes = 7.6 MiB Load Address: 82000000 Entry Point: 82000000 Verifying Checksum ... OK => tftp 82000000 zImage done Bytes transferred = 7954880 (7961c0 hex) ## Checking Image at 82000000 ... Unknown image format! => iminfo 82000040 ## Checking Image at 82000040 ...
