You have to specify the filename also, you are not doing so in the example above.

Dear p.bevilacqua ,

Thanks for interset

But i specified the file name as shown with the same error message

Abba_Test#upgrade rom-monitor file usbflash0:C2800NM_RM2.srec.124-13r.T

%Error: srec file read failed

BR,

Mohamed Ibrahim

Correct filename should be C2800NM_RM2.srec.124-13r.T6

Check that you file is not corrupt and try again.

Dear p.bevilacqua ,

I downloaded this IOS from CISCO Web site and it is C2800NM_RM2.srec.124-13r.T NOT C2800NM_RM2.srec.124-13r.T6

Is there is special USB flash type dedicated for that ?

I've verified this right now and indeed T6 is the correct filename, so check again.

You can verify that your usb stick works Ok by copying some files from/to regular flash for a test.

If still trouble, use TFTP that works all the times.

Nope. I upgraded my routers (1800/2800/3800) ROMmon using USB and it worked. What is the specific model of the router? Is it a 2811 or a 2821/2841?
