Well, looking in the source code, I see a single place with a similar
error message:

 786         rc = ioctl (fd, MEMGETINFO, &mtdinfo);
 787         if (rc < 0) {
 788                 perror ("Cannot get MTD information");
 789                 return -1;
 790         }

But then, the error message would be:

Cannot get MTD information: XXX XXX XXX

with "XXX XXX XXX" giving an explanation of what goes wrong.

What was the "XXX XXX XXX" that got printed in your case?

Are you sure this is correct? Your environment size is only 4 KiB?
And your flash secor size is 64 KiB?

Best regards,

papers while seated between two portly passengers will recognize  the
difference -- one can see only a very few things at once.
