i have one Cisco 4402 Contoler which is running in image 4.0 Version, and i tried to upgrade this image to 5.0 , but it stops tranfering data once it reached 33 MB of size, am using TFTP-D32 as tftp server, ( i checked Cisco TFTP Server too ), but all the case response is same, So can anybody let me know how can i solve this issue.
Is there any command which will show us the size of flash: to ceck whether flash is full or not.
Check the release notes for the version you are trying to upgrade to. There are some interim upgrades you will have to do. The format of the flash was changed which is why you have to do these interim upgrades and why its failing.
