I just upgraded a Cisco 2801 Router from 12.4(5) to 12.4(15)T (ED) and i get that warning (or errors) message at the end of booting:
amd_flash_cmd: timeout on write sector command
environment write to NVRAM failed
Every thing seems ok, i get command prompt after that.
Any help to explain to me that is welcome.
Any help will be helpful,
