Cisco router error "ROMmon (rommon 1 >): " problem

[medzeinmaaloum]

Every day after starting my 3925 router, displays the message:

ROMmon (rommon 1 >):

I reload the boot (boot flash: c3900-universalk9-mz.SPA.154-3.M3.bin) every time, is there a solution for this?

Thanks

[Elliot Dierksen]

This past thread addresses that issue. https://community.cisco.com/t5/switching/change-boot-system-ios/td-p/3360657 

[medzeinmaaloum]

I haven't found a solution!

[Elliot Dierksen]

Please either share the complete router config, or at least part of it. If you want to do a partial config, do this.

show run | incl boot

It would also be helpful to know how the configuration register is set.

You need this in your config.

boot system flash flash:c3900-universalk9-mz.SPA.154-3.M3.bin

[medzeinmaaloum]

Ok, how?

[medzeinmaaloum]

any progress about that?

[medzeinmaaloum]

Good evening,

The problem "ROMmon (rommon 1 >): is not solved yet, each time I start my router it displays the message:

ROMmon (rommon 1 >

I have to load the image each time:

I reload the boot (boot flash: c3900-universalk9-mz.SPA.154-3.M3.bin) every time, is there a solution for this?

[Elliot Dierksen]

When I said "put this in your config", that means "config t" and enter the command I gave you and write it.

[medzeinmaaloum]

Good day,

I ran the command yesterday:

Voice_Projets(config)#

Voice_Projets(config)# boot system flash flash:c3900-universalk9-mz.SPA.154-3.M3.bin

Voice_Projets(config)#do write

Building configuration...

[OK]

Voice_Projets(config)#

And when I start the router this morning it still displays the same message, I had to load the image again c3900-universalk9-mz.SPA.154-3.M3.bin :

monitor: command "~" not found

rommon 2 >

[Elliot Dierksen]

Disconnect the cable from the console (and aux port if applicable), then power cycle the router. Does it boot correctly then?

[medzeinmaaloum]

yes when I disconnect the cables from the router it starts without problem

[Elliot Dierksen]

Then your serial port or your terminal emulation program is generating some kind of output during the boot process that is interrupting it.

[medzeinmaaloum]

so is, how can i solve this?
