Yes of course, my mistake - sorry. But by the way, is there a possibility for safely update u-boot?
Yes, if you have hardware to support this (i. e. two flash banks that can be swapped, where the "switch" can be controlled by software, remembers it's state when powered off *and* has some kid of watchdog function to toggle back to the other position in case the system does not come up). Not many systems support this ;-)

If I don't document something, it's usually either for a good reason,
or a bad reason. In this case it's a good reason. :-)
