[U-Boot-Users] duplicate environment variables in U-Boot? (full log)

[Clemens Koller]

Hello, again...

I forgot to attach the full log to help you to get
an idea of what I mean. Some of the 'Unknown commands'
should be known, actually.

Best regards,

Clemens Koller

I'm afraid this "log" is useless, too. Obviously it was  captured  by
copy  &  paste  from  a  console  window  (visible for example by the
wrapped long lines). You will never see  any  control  characters  or
escape sequences this way.

Best regards,

I know exactly, what you mean... I had no time/chance yet to get
a binary log of the data.
Maybe it would be a good idea to either ignore control characters in
the environment or show (escape) them properly? If I have these
duplicate values, I cannot delete them afterwards (without an
binary dump of my terminal) and... if I wrote them to flash
occasionally... well, ok, I don't see any high priority here.
It's just a little annoying.

Best greets,

Clemens Koller

I'm not sure if I want to do this.

Yes, I understand. But then - maybe one day command line history gets
added, and then escape sequences will have to be interpreted anyway.

Just for the records - for environments in flash the "md" command is
of course your friend to see what special characters crept into the
variable names.  Other environment storage locations are left to the
reader as an excercise.  Note that this is only possible because the
environment is saved in such an "unefficient way".
