IR 829 breaks in rommon

[mgallissot]

Hi,

I've a IR 829 router, which stops during the boot process in rommon 2. My config-register is 0x102. How to get the router to boot automatically the image in flash ?

Cheers,

Mathieu

hey 0x102 should boot the ios if its not corrupt, was this working before ?

when you try and boot from rommon does it just revert back , is there only 1 image on the router to boot ?

Configuration Register Setting	Router Behavior
0x102	Ignores break 9600 console baud
0x1202	1200 baud rate
0x2101	Boots into bootstrap Ignores break Boots into ROM if initial boot fails 9600 console baud rate
0x2102	Ignores break Boots into ROM if initial boot fails 9600 console baud rate default value for most platforms
0x2120	Boots into ROMmon 19200 console speed
0x2122	Ignores break Boots into ROM if initial boot fails 19200 console baud rate
0x2124	NetBoot Ignores break Boots into ROM if initial boot fails 19200 console speed
0x2142	Ignores break Boots into ROM if initial boot fails 9600 console baud rate Ignores the contents of Non-Volatile RAM (NVRAM) (ignores configuration)
0x2902	Ignores break Boots into ROM if initial boot fails 4800 console baud rate

Yes, it was working before, I don't know what happened. I just have one image, and I can boot it manually  (boot [image-name])

[Mark Malone]

Ok so it works manually thats good the image is ok then , i would still while you have it up upload another image into flash always good to have a backup image incase of corruption during boot process

when you boot it from rommon what does the show version provide in section system retuened to ---

when you try set it to 0x2102 does it do the same thing, it may be hardware related did you capture the boot process when consoled in it will provide more information of where its exactly failing

[mgallissot]

show version provides :

System returned to ROM by Power-on at xxx
System image file is "flash:ir800-universalk9-mz.SPA.155-3.M"
Last reload reason : Power-on

I couldn't manage to change the config-register, I don't have this command 

Router(config)# config-register

[Mark Malone]

it sounds as if its not picking up flash on th bootup any you have to manually boot it which could be hardware as its an automated process , power-on is ok to see that its normal standard startup, are you able to change the config-register from rommon -----confreg 0x2102

this link has few other tips on things to try put a new image in from xmodem in rommon just in case something is gone wrong with it , if you can post the actual boot process when your consoled in it should show where its breaking as it goes through and gets set to rommon

Thanls Mark, I don't have the confreg commend either in rommon. You'll find the console output when booting the device.

try your manual boot. From IOS exec mode do a bundle install flash:/ir800-universalk9-bundle.SPA.155-3.M2.bin (that file should be in flash).

This worked for me in a IR809, hope it helps.

Hi Mathieu,

I realise your topic is a month old,

I just come across something very similar with the Cisco IR809 router, these things appear to be a little different to the ISR's which I am used to.

I was able to get to to reliably boot every time by using the boot system command in global config mode;

boot system flash:/ir800-universalk9-mz.SPA.155-2.25.M0.4

Additionally, if you erase the startup-configuration it appears that you have to boot the IOS manually from rommon again and then add the boot system command.

Hope this helps

I frequently have this problem with IR829 routers. I'm dealing with one right now that is proving very stubborn. I have the boot command in the startup config, correct file name.

When issuing a reload command, everything is fine. But if the device is powered off and back on, it stops in rommon. None of the commands I know for viewing or changing the config register are available. 

rommon-2> ?
? Print the command list
boot Boot image
dir List file contents on a device
help Print the command list or the specific command usage
iomem Set iomem size in percent
reboot Reboot the system
set Set environment variable and network configuration
show Show loader configuration
unset Unset environment variable

I tried set but it doesn't look like confreg is an option.

rommon-2> help set
set: set Set environment variable and network configuration
usage: set VARIABLE=VALUE
set {ip | gw | mac } addr [mask]

Description: Set environment variable, for example set TEST="foo".
Set and save IP/default-gateway configuration parameters.

So with the boot command in startup config, it still didn't boot properly for me. What got it to work was writing the startup config to a file in flash, then putting this in the config:

boot system flash:/ir800-universalk9-mz.SPA.156-3.M
boot config flash:/ROUTERSTART.config
