cisco ISR4331 tftpdnld not found

[Fotiosmark]

Hello team,

I am trying to upload new image to a cisco ISR4331.

I am at the Rommon> where I put the below commands.

rommon 2 > IP_ADDRESS=10.0.0.1
rommon 3 > IP_SUBNET_MASK=255.255.255.0
rommon 4 > TFTP_SERVER=10.0.0.2    == my pc ip tftpser
rommon 5 > DEFAULT_GATEWAY=10.0.0.2
rommon 6 > TFTP_FILE=isr4300-universalk9.16.07.02.SPA
rommon 9 > tftpdnld

monitor: command "tftpdnld" not found

I can't understand why since I already did the same thing on the same router for a different image.

Please help.

Can you please check the tftpdnld command shows by typing help on rommon mode and if yes, please see your TFTP_FILE name, generally file ends with extension like .bin.

The reason why "tftpdnld" may have been removed is because uploading an IOS via xmodem/ymodem or tftpdnld has gone out of "fashion" since the router has a removable compact flash (CF) and a USB slot.
(Using either the CF or the USB slot is way faster than doing xmodem/ymodem or tftpdnld.)

Hi,

So if it has flash or usb, how to I make it boot from the usb, or copy the image from the USB to nvram and boot it from there.

I alsays used tftpdnld (which is fast enough for me)

Thanks

Command:  boot usb0:filename.bin

[Ryota Takao]

you can use the following command instead of tftpdnld.

rommon X > boot tftp:<image_name>

Use the following command 

boot tftp:filename.bin

and when your ios is loaded please do copy tftp: flash: command and then make it as default boot

This syntax is not going to work.
