Try realoding the image or boot straight without writing to flash, using the option in tftpdnld.

Were you trying to upgrade the memory before this error message started appearing?

Hi ,

Another simple way to load new image is first load the image in RAM using xmodem command ie ..

xmodem filename -r

Router boots with the image stored in DRAM.

After that make sure that router is not reloaded until you load the image to flash using tftp server.

Once you load the image using tftp reload the router and make sure that config-reg value must be 0x2102.

If you face the same problem after following the above procedure check the flash once.

Hope this helps you.

Thanks,

Satish
