VG202 - Corrupt Flash?

[Andy Hewitt]

Hi all,

I've got a VG202 I've recently removed from an installation as it was reported as faulty.  (Lines showing as engaged/no dial tone despite not being in use and gateway showing no active calls)

Back at my desk, trying to boot into the thing it freezes at the below stage and goes no further.

Accessing in ROMMON mode I've tried to replace the firmware by both tftp and xmodem but I get flash errors each time.  Either not enough room or unable to write file.

On running a dir flash: I get the error:

The device is not recognizable.

dir: cannot open device "flash:"

Is there anything I can do or is it destined for the scrapheap?

Thanks

Andy

Hi Andy,

Before you send this VG to the dustbin.

Try this :-

rommon 1 > IP_ADDRESS=10.1.1.1
rommon 2 > IP_SUBNET_MASK=255.255.255.0
rommon 3 > DEFAULT_GATEWAY=10.1.1.2   
rommon 4 > TFTP_SERVER=10.1.1.2
rommon 5 > TFTP_FILE=YOUR_IOS_FILE.bin
rommon 6 >  set

Note tftpdnld can have a syntax of tftpdnld – r.
Entering -r downloads and boots the new software but
does not save the software to flash memory.
An IOS will require downloading on to the router when fully booted up.

2. Issue set command to check settings before tftpdnld

rommon 7> PS1=rommon ! >
WARM_REBOOT=FALSE
BSI=0
RANDOM_NUM=1795826770

DEFAULT_GATEWAY=10.1.1.2
TFTP_SERVER=10.1.1.2
TFTP_FILE=YOUR_IOS_FILE.bin

3. Start the download using tftpdnld –r

rommon 7 > tftpdnld -r

            IP_ADDRESS: 10.1.1.1
        IP_SUBNET_MASK: 255.255.255.0

         TFTP_VERBOSE: Progress
     TFTP_RETRY_COUNT: 18
         TFTP_TIMEOUT: 7200
        TFTP_CHECKSUM: Yes
               FE_PORT: 0
        FE_SPEED_MODE: Auto Detect

Now you should be at the ROUTER> prompt
Go to enable ROUTER#

Now try
dir or show flash

You may now be able to format the flash

router#format flash

when this finishes copy the IOS as normal from the TFTP server

Worth a try
