Hm... one of the boards I don't have access to; can you please help
debug the problem?

Hm... I don't think so, but as it's failing there must be some bug
somewhere... My thinking is that all the relevant environment handling
that actually uses errno is related to the hash table handling, and
all this runs definitely only after relocation to RAM, so this should
not be the problem.

What we see here is in the pre-relocation phase, where we are still
parsing the original, in-flash copy of the stringified environment.
What is strange is that this seems to have worked when accessing
"baudrate" (either because the environment was found, or because the
default environment was used), but is stopping here.

Can you attach a debugger and check?

Best regards,

Wolfgang Denk
