It is definitively a good starting but it is even more puzzling: - if uboot version changed from fido to jethro... it seems it is still working since I can see the penguin logo - the kernel didn't change. I'm using 4.1 in fido and jethro. Anyway... I'll check in the direction you pointed. thanks -- Ivan Sergio Borgonovo http://www.webthatworks.it
