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:
IP_ADDRESS: 192.168.0.160
IP_SUBNET_MASK: 255.255.255.0
DEFAULT_GATEWAY: 192.168.0.1
TFTP_SERVER: 192.168.0.7
TFTP_FILE: isr4300-universalk9.17.09.04a.SPA.bin
TFTP_MACADDR: AC:F5:E6:0E:5B:AF
ETHER_PORT: 0

Post the complete output to the command "sh run | include boot".

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".

I went ahead and deleted files from flash, bootflash etc and installed the updated ronmon and ios from scratch. All is working now.
