Deleting read-only environment variable on Sibyte board.

Deleting read-only environment variable on Sibyte board.

[Ralf Baechle]

I've got a read-only environment variable on my Sibyte/Broadcom Bigsur
system.  Annoyingly it's the network address.  Any help on how to
delete such an undeletable environment variable would be welcome.

Thanks,

  Ralf

Hi Ralf,
 
Can you try 'Unsetenv [NAME]'?

I'm getting an error message, something about the variable being read-only.

Thanks anyway,

  Ralf

It looks like the variable was set with 'setenv -ro' command. This will
need a manual delete.
Bad news -  This would probably require a new firmware build.  There is
no current command to remove -ro variables (non-existing feature).

I ran over a bit of documentation regarding how variables are stored by
CFE.  Looks easy enough to write a little app to convert those variables
to writeable.
