I saw message "Not enough free memory" but my image size < RAM's size.
I found that -
Router boots in boot mode, with the following message on the console:
SYSTEM INIT: INSUFFICIENT MEMORY TO
BOOT THE IMAGE!
This message only occurs when loading images that run from RAM (for example, c1600-y-mz.120-20). Since Cisco1601-1604 routers support images that run in RAM and images that run directly from Flash (for example, relocatable images), there are two solutions for the problem:
-Upgrade the Dynamic RAM (DRAM
-Load a relocatable image (such as c1600-y-l.120-20). On Cisco1605 routers, the only option is to upgrade the DRAM.
I used relocatable image. And is't possible to resolve it without upgrade DRAM?
