I have a 867 VAE router that has reported a flash checksum error.
The exact model is reported as C867 VAE K9 256Mb
The Error message is
Error : compressed image checksum is incorrect 0x30F65239
Expected a checksum of 0x30F64E18
I am trying to boot directly to an image stored on my TFTP server to recover the device. I have read many articles about how to do this and can't see what I'm missing. When I try and download the image with tftpdnld -r it waits about a minute or so and then reports.
TFTP boot exit: File not found
I have tested my TFTP Server by downloading the file successfully with a tftp client on a windows machine. Both the router and my TFTP Server are connected to the same LAN segment with straight through cables using a switch not directly connected via a cross over cable.
I have tried both with and without the leading / in the filename.
I have tried the LAN cable connected to GE0 and FE0 with the same result.
I have confirmed that 10.2.2.9 is not in use on my network.
The size of the image file is 35,951,012 bytes
Here is the output of the tftpd command
rommon 18 > tftpdnld -r
DOWNLOAD_PORT: 0 (LAN FE 0..3, LAN GE 4 for ADV K9, WAN GE 5)
As a background this switch was left switched off on the shelf for a couple of years as it was surplus to requirements.
Now we have a use for it again. I'm hoping to try and format the flash memory once I get it booted to IOS, I'll boot from USB if the flash proves unusable. Any Ideas what I'm doing wrong here?
Thanks in advance
