I have just downloaded a new image to flash via a serial cable on a Cisco 837. The Download completed and then erazed the flash, but the checksum failed. Here is the output:
Expected checksum: 3d7a, calculated checksum:814
open: file "c837-k9o3y6-mz.124-5a.bin" not found
open(): open Error = -1
loadprog: error - on file open
Any ideas what to do next?
