boot: cannot load "bootflash:" in a loop and no rommon prompt

[damiensarazin]

Hello,

i have recently tried to change the catos on a Catalyst 2948G-L3 and since then i have the following message in a loop :

loadprog: bad file magic number: 0x0

boot: cannot load "bootflash:"

rommon: cold reset frame @0x0000000

rommon: reading reset reason register

rommon: valid nvram config

system bootstrap, version 12.0(7)w5(15a) release software

rommon: initializing exceptions

rommon: initializing TLB

rommon: Initializing cache

rommon: Sizing and zeroing main memory ... 64 MBytes

rommon: Sizing non-volalite memory ... 128 KBytes

loadprog: bad file magic number: 0x0

boot: cannot load "bootflash:"

.........

I know that the solution would be to download a new valid image from tftp via the rommon prompt but what i dont undertand is why i cant access the rommon prompt.

Do you have an idea ?

loadprog: bad file magic number: 0x0

This could mean one of two things:

1.  The CatOS you uploaded is corrupt; or

2.  The flash has failed.

i figured that reading forums but is there anyway to resolve that problem without being able to use the rommon prompt ?

No one got any idea on why i cant have the rommon prompt to recover an image ?

Hello Damien,

It might help to post in Home > Netpro > Network Infrastructure > WAN, Routing and Switching . As this section is for small business devices and the 2948 is handled by enterprise support.
