I am trying to copy a 12.2 IOS image onto my 2522. (It's currently got 12.0(8) but I want it to do IS-IS routing.)
There is a 12.2 image on my PC which I have copied successfully onto my 2502's, my 2521, and one of my 2501's without any probs.
Whenever I copy it onto the 2522, the transfer looks like it's going fine and then when it's time for checksum verification, I get this:
[OK - 16505800/16777216 bytes]
Verifying checksum... invalid (expected 0x7081, computed 0x5944)
Flash copy took 0:09:46 [hh:mm:ss]
%FLH: Re-booting system after download
Flash boot: No bootable files found in flash.
File boot failed -- File not accessible
...*** BOOTING ROM IMAGE ***
System Bootstrap, Version 11.0(10c), SOFTWARE
And there it goes, booting right up in Rxboot mode.
I keep a copy of the old 12.0(8) image on my PC, which I copied back onto the 2522 while it was in Rxboot mode and no probs. Good checksum and everything.
Since it comes to the 2522 over an Ethernet crossover link from Sethtek-A which has a serial link to Sethtek-G which shares a token-ring segment with the PC, I also tried copying the 12.2 image straight over the Ethernet link from Sethtek-A (which has that image installed in Flash), but I had the exact same checksum problem.
This 2522 has the same memory as all my other 2500-serieseseses that have the image installed just fine:
System flash directory:
File Length Name/status
1 16505800 /c2500-jk8os-l.122-1d.bin [invalid checksum]
[16505864 bytes used, 271352 available, 16777216 total]
16384K bytes of processor board System flash (Read/Write)
So what's my problem?
