this is what I suspect, but I don't have any idea how I can check it. I mean, how can I see where the decompressed image is put? I tried giving a look at lib/inflate.c to check how gunzip() works, but I'm not able to figure out where inflated data goes....
Look at the code in common/cmd_bootm.c . IIRC the ramdisk is copied to the end of RAM. The boot output should also give some hints. You'll need to provide more information such as your bootlog, the commands you're using to boot and your memory/flash setup for us to help.
eventually yesterday I've been able to boot with initrd and not initramfs by leaving the kernel in the flash memory and coping the initrd in ram. With the exception of switching to initrd, the kernel is the same, so I really think it was a problem of overwritten memory.
I'll have to find out why booting the kernel from flash works and from ram not.
