A quick question from me , can I update my fc21 installation on a banana-pi
, to use the latest uboot ? I have a fc21 production server based on
banana-pi , and was wandering is there an update path/method to get the
latest and greatest uboot into my machine without any pain . The server runs
24/7 but could tolerate a little down time .
You can just dd out the appropriate u-boot from a running device with
the command below and then just reboot. You can grab newer Fedora
u-boot builds from koji  to use those.
sudo dd if=/usr/share/uboot/$TARGET/u-boot-sunxi-with-spl.bin
of=$MEDIA bs=1024 seek=8; sync
There's work being done on some utilities to make this easier to do.
