I bought one 32(2*16MB) mb flash.
i cant upgrade the flash. i am trying using following methods:
1) boot the router with a good flash image and then take that flash out and
insert the new flash. as 3640 take the ios image into DRAM and run from there.
then using cpy tftp: flash: command
and it can't erase the flash. at some point of erasing the router just
stuck. i got the following result:
Router#copy tftp: flash:
Address or name of remote host
%Warning:There is a file already existing with this
Do you want to over write? [confirm]
Erase flash: before copying? [confirm]
Erasing the flash filesystem will remove all files! Continue?
(IT STUCK HERE )
then i tried from rommon mode using xmodem command. but still i failed
because it says it cann't erase the flash.
Is there any other way that i can use to upgrade the flash.
any help will be highly appreciated.
