[c-nsp] Boot from TFTP

Fri Jun 24 16:50:40 EDT 2011

I would try booting from the current image on the flash. Then, inside the running IOS, copy that image to the tftp server just in case. Then, erase the flash and copy the new image to the flash and reload. At least if the new image still doesn't work you can tftpdnld via ROMMON the original image from the tftp server that was working.

Good luck.

OK... I'm in a pinch and I need to upgrade a 2821 to a newer ISO and don't
have time to get a new Flash card.

So i'm trying to boot from TFTP.  But I keep getting a file to large error

%DHCP-6-ADDRESS_ASSIGN: Interface GigabitEthernet0/0 assigned DHCP address
10.14.1.53, mask 255.255.255.0, hostname Router

%SYS-6-READ_BOOTFILE_FAIL: tftp://
10.14.1.108/c2800nm-advipservicesk9-mz.151-3.T1.bin File read failed -- Not
enough space.

%SYS-3-IMAGE_TOO_BIG: 'tftp://
10.14.1.108/c2800nm-advipservicesk9-mz.151-3.T1.bin' is too large for
available memory (51691544 bytes).
%SYS-6-READ_BOOTFILE_FAIL: tftp://
10.14.1.108/c2800nm-advipservicesk9-mz.151-3.T1.bin File read failed -- Not
enough space.

Config looks like this:  boot system tftp://
10.14.1.108/c2800nm-advipservicesk9-mz.151-3.T1.bin

Memory needed is 512mb  I have "Cisco 2821 (revision 53.50) with
776192K/10240K bytes of memory."  so I should have enough ram.

What am I missing?
