I have two 2811 routers with two 64MB flash cards.
One router is going to rommon mode and giving me following error with both flash cards:
rommon 8 > dir flash:
Checksum failed on piptom-atafslib-m
Expected checksum: 9338, calculated checksum: ab38
open: file "piptom-atafslib-m" not found
open(): Open Error = -1
loadprog: error - on file open
cannot load the monitor library "bootflash:%piptom-atafslib-m"
from device: compact flashdir: cannot open device "flash:"
However other router is booting perfectly fine with those two flash cards without any issue.
