I cannot upgrade a wlc 4402 from release 5.2.178 to release 6.0.188.

When I try to tranfer the new release the download cannot complete and the log is

%TFTP-3-WRITE_NOCLOSE_FAIL: tftp_client.c:147 Error while writing the local file: No space left on device

How can I delete a file on the flash or view the available space?!

Thanks and Regards

With that error typically you just need to reboot the controller and try the upgrade again.

We resolve the problem changing the tftp server.

The old tftp servers were pumpkin and solawind, the new tftp server is tftp32 v3.35. The right one!!

Now the problem is install the emeregency image AIR-WLC4400-K9-5-2-157-0-ER.aes.

We can download the image into the controller without errors, but when we reboot the sysinfo remain with

Emergency Image Version.......................... N/A

Can you help us?!
