Recovering from Failed Upgrade

AP Model: AIR-AP1220B-E-K9


We recently tried to upgrade this from VXWorks 12.03T to IOS, but something went wrong. We now get the following prompt only:


c -- Copy file

f -- File dir

l -- downLoad file into DRAM

u -- Upload file

p -- xfer Protocol

n -- coNsole

r -- Run

s -- System info.


I've therefore redownloaded the 12.03T VXworks image file and uploaded it via the console cable using 1K-Xmodem and baud rate 115200. The file appears to upload successfully, so I click r for run, but keep getting the following output:


a -- EnterpriseAP Sys 12.03

a


Inflating "EnterpriseAP Sys 12.03"...

** Error in Compression Codes



*** Bad CRC in File DRAM :00008720


Memory Bank total used left

DRAM 16742624 0 16742624

Config 524288 0 524288

FLASH 7602176 0 7602176


Memory Bank:File address size encoding type flags


*** Decode Error 00000001


I've tried this a few times now and redownloaded the image incase it was corrupt but with the same problem.


Can anyone help me? Cheers!

Hi Paul,


Have a look at the following;


Verify that the connection settings in the terminal application are 9600-8-None-1 and NO flow control (not hardware or software).
