[c-nsp] Image in slot0: vs. flash after reload

[Thomas Renzy]

Hello John,

Assuming that your config-register is set to something like 0x2102, its
probably booting from the BOOT parameter in rommon mode. If your able to
(if you can) bring the router into rommon mode, I would check to see if
this parameter is set and to reset it accordingly. The "set" command in
rommon should tell you all the parameters you need.

rommon 1> set

Hope this helps.

Thomas

The really weird thing that I can't figure out is that I don't have any
"boot system" commands in the config, so why was it running the correct
image in flash before it reloaded? I don't understand how that could
have happened. The router reloaded due to a software forced crash. I
wonder if that somehow caused it to boot the wrong image? I can't
imagine that a software forced crash would current the image in flash.
Is it possible that the image in flash isn't any good so the router
automatically decided to try slot0:, even without the "boot system"
commands?

This is really baking my noodle. I need to figure out why it's behaving
this way before I do anything to it.

Thanks!
John

That is consistent with my experience.  Not that I like it.  I am
"guessing" that the presumption was that if you had a card in the slot,
and there was an image there, it was the "newer" one, and the boot flash
was the fallback.
Same thing happens by the way) if you have firmware on flash card.

Thinking about where the 3640 was targeted (remote offices), it might
have been because it would be easier to have updates shipped by flash
card, or a backup image on a flash card.
