i have problem memory not enough

[khudayersinan88665]

 

I bought a router  and it did not have iso only running in rommon and when I try to download iso image via xmodem I get an error message that the memory is not enough and when I write the dir flash command, I will not see any iso and .My question is is there a way to delete the memory files or a solution to this problem

what is the model of the device? 

Power off the device - connect the console post complete output until you see romon >

If this is an 1841, what is the ROMMON output to the command "dir flash:"?

Another thing, 1841 uses a compact flash (CF) to store files and IOS.  Does this come with one or not?

[balaji.bandi]

check what is there in the flash for now : (issuing dir command)

what is the IOS version you trying to upload? what size is this ?

follow the thread : which give you information how you can upload the firmware using xmodem, do not ask us how you can get the Firmware, you can google you get many available sites and you can use it for Lab purpose.

Looks like CF card having an issue :

Turn off the Router, eject CF card, format with Windows (if you have multi-card reader) with fat 16 format.

follow again below link to load IOS using xmodem ?

i can not remember 1841 do have USB right, so you can use USB to load IOS and format flash.

1841 have two USB ports, however, to use these ports in ROMMON, the ROMMON firmware needs to be updated.  Very high chance nobody knows about this.
