2801 Cannot Boot IOS From TFTP

Hi guys, today i want to boot my Router's IOS from TFTP server but when I use the command:

boot system tftp c2801-adventerprisek9_ivs-mz.124-24.T7.bin 172.16.10.200; after that I write-mem, it shows the log:

Router#wr

Building configuration...

ROMMON: out of room in table, cannot set "BOOT"

*Aug 29 01:05:44.171: %MONITOR-3-VARSETFAIL: ROM monitor variable set of "BOOT" failed.[OK]

And when I reload the router, it cannot boot IOS from TFTP Server, sure my TFTP work well and 2801 can ping to TFTP. How can I do in this case?

This i my config:

Router#show run

Building configuration...

Current configuration : 772 bytes

Hi Tran,

Error Message     

%MONITOR-3-VARSETFAIL : ROM monitor variable set of '[chars]' failed.

Explanation : The system could not set a ROM Monitor variable. This condition typically occurs when no ROM monitor memory is available to save the variable. The ROM monitor memory is most likely already filled with configuration boot commands.

Recommended Action: Enter the show bootvar command and review the output to see if there is anything unusual with the system. Try to reduce the number of configuration boot commands.

Regards

Please rate if it helps.
