Dear M=E5rten Wikman,

I dunno about the Yocto ML, but usually you don't want to be top-posting in=
 the=20
ML.

Yes, that is likely. You can also use ' sf update ', which is less abbrasiv=
e for=20
the flash (it first reads the SF, then does erase+write cycle only if the b=
lock=20
changed). But for the first installation of u-boot, use erase + write manua=
lly=20
to make sure everything is written correctly.

OK. Make sure that you can even write the SF correctly in the first place.
