I have Cisco 831 router and have been trying to upgrade to newer IOS version (c831-k9o3sy6-mz.123-11.T2)
Since I performed my ugrade, the system keeps crashing and looping itself. Here is the description:
CHnaging crypto engine: Onboard: 0 state change to: INIT
System INIT: INSUFFICIENT MEMORY TO BOOT FILE IMAGE!
Software-forced reload
.
.
.
.
***System received a Software forced crash***
After that it restarts again, decompresing image and showing te same error.
I assume that it cannot boot properly because IOS image file is bigger than the available flash memiry on my router...
I've been trying to use Ctrl+Break and then:
rommon1> confreg 0x2142
rommon2> reset
but it just can't get to the command prompt of the router to perform following command: copy tftp flash (with the good, reliable IOS image on TFTP server)
Please help me solve my problem to load former IOS back on the router!
