Solved: I have the exact same problem

miikakirves · ‎11-15-2010

Hi there,

I'm facing a bit challenging problem. When I boot one accesspoint it gives only next listing in the screen:

Xmodem file system is available.

Flashfs[0]: unable to allocate available block.

The system has been interrupted, or encountered an error during initializion of the flash filesystem.

The foolowing commands will initialize the flash filesystem, and finish loading the operating system software:

flash_init

ether_init

tftp_init

boot

When I type this commands, it doesn't help at all. The output will be following:

ap: flash_init

Initializing Flash...

flashfs[0]: out of memory

...done Initializing Flash.

ap: ether_init

Initializing ethernet port 0...

Reset ethernet port 0...

Reset done!

ap: tftp_init

Unable to get our ip address: no "IP_ADDR" variable set

ap: boot

Loading ""...; permission denied

Error loading ""

Interrupt within 5 seconds to abort boot process.

Boot process failed...

ap:

I've tried to set ip address, but flash is out of memory and even tried other measures like: Restore IOS on Cisco AP1200https://supportforums.cisco.com/thread/326515?referring_site=kapi but none seemed to work. It just doesn't take the IOS in it.

What to do?

KR, Miika

Hardware issues tend to happen suddenly :-)

I'm not sure there is anything else to do than returning the unit under RMA ?

Looks like a hardware condition caused this.

That's a true. Is there any other opinions with this? Do I really have to send this device back to Cisco?

At the ap: prompt, issue the flash_init command

Once its done Initializing Flash Issue the dir flash: command in order to view the contents of Flash, and find the config.txt configuration file.

Rename the config.txt file to config.old with the command rename flash:config.txt flash:config.old

Issue the reset command in order to reboot the AP

Hi everyone,

This is solved yesterday.

We used PoE switch while we tried TFTP boot. It didn't work at all. After we plugged power source and cable DIRECTLY to computer this started to work..

Sorry for bothering you all with this quite simple task.
