... Although I tried manually copying zImage into /home/user/MyDocs/bootmenu.d/ folder and it gave an error. Elsewhere in MyDocs I can cut/copy stuff. ...
Btw the command u-boot-update-bootmenu ... does it need to be run as root ?
I tried with 2012.04-1 and got the mkimage error I posted above. I did not test with 2012.04-2 because I read in the threads that it is not suitable for hw rev 2204.
