Correction: automatic boot is possible with entries in /etc/boot.con:
set tty fb0
boot sd1a:/bsd # in this case the systems boots from the usb ssd.
In this stage the BananaPi's do everything I need. Audio, wlan, are not
yet tested, because I don't need it.
Thanks again for the wonderfull u-boot.bin.
