cannot load ios in ronmon

moman62 — Tue, 11 Feb 2025 20:02:13 GMT

I am trying to load the updated ios in ronmon on Cisco 4331 router and it will not load. I tried using the old tftpdnld command and that did not work either.

rommon 1 > IP_ADDRESS=192.168.0.160
rommon 2 > IP_SUBNET_MASK=255.255.255.0
rommon 3 > TFTP_SERVER=192.168.0.7
rommon 4 > DEFAULT_GATEWAY=192.168.0.1
rommon 5 > TFTP_FILE=isr4300-universalk9.17.09.04a.SPA.bin
rommon 6 > boot tftp:

@moman62

How about connectivity? Can you ping the tftp server and vice-versa?

Are your tftp server listening on the right interface of your PC?

Try to copy the IOS to the 4331 using usbdriver instead. You have some connectivity issue.

can i use any size usb drive? or is there a limitation?

Re: cannot load ios in ronmon

Copying any file(s) into the flash while the appliance is still in ROMMON is not supported in IOS-XE due to security vulnerability.

Copy the firmware into a USB flash (FAT16) and then force the router to boot the firmware off the USB flash drive using the following command:

boot usb0:isr4300-universalk9.17.09.04a.SPA.bin

While in ROMMON, please post the complete output to the command "dir flash:".

Try this command:

boot usb0:isr4300-universalk9.17.09.04a.SPA.bin

If the router does not boot this firmware, please post the complete output to the ROMMON command of "set".

if the router boots fine, please post the complete output to the command "sh romvar".

Boot variable string syntax is incorrect.

Here is how to correct it:

conf t no boot system flash bootflash/isr4300-universalk9.17.09.04a.SPA.bin boot system flash bootflash:isr4300-universalk9.17.09.04a.SPA.bin end wr

(Make sure the firmware is already in the flash before rebooting the router.)

I made a mistake. I asked for the wrong output.

Please post the output to the following command:

sh run | BEGIN boot-start

Post only the "first page". I don't want the whole output, just the first page.

Ok, so there is no active boot-variable string. So I have no idea where the incorrect syntax came from.

Let's try fixing it by overwriting:

conf t boot system flash bootflash:isr4300-universalk9.17.09.04a.SPA.bin end wr

After saving the config, check using the command "sh boot".
