I'm trying to upgrade a 1720 router Flash carad. I bought a
16MB card for it. If i place the card in and try to boot, it boots to ROMMON1. Tried the confreg proceudre and all, but still couldnt boot. I booted the router with the old flashcard and it's fine. I popped in the new card after it was booted from old card, and did erase flash: and it went through the erase procedure. If i run "show flash: all" with the new card in it says the new card only has 4 MB of free space. How should I go about this? I am unable to format with Class C filesystem, the format command is not available. Is there a process I need to go through to get the router to correctly recognize the new card? Thanks! - Scott
Thanks for the reply Mike. I should have thought of trying that before, but unfortunately, it didnt work anyway. Apparently its not a valid command in this IOS version c1700-y-m v12.0(4)T. I just get "invalid input detected" when trying to squeeze flash: ...
Figured it out with help from the flash card vendor. Ill post results in case anyone else has this problem;
The IOS version was 12.0 (4) T and was too old to be able to see 16MB of flash card. To get around it, I had to load a newer IOS directly into DRAM (skipping the flash card). Once booted do a erase flash: and then copy the newer IOS to the flash card via TFTP and reload. Here is the command set:
tftpdnld –r (the –r tells the router to decompress directly into the DRAM, it will not be saved to the flash)
once the router boots up, issue commands erase flash: or format flash: one of those will work.
TFTP the image you eventually want to run on this router.
