OK,

at this point you need to login as admin and do :

[dderidde-ex90-home:~] $ tsh

Welcome to dderidde.ex90.home

TANDBERG Codec Release TC5.1.5.-Beta1 (TEST SW, r296765)

SW Release Date: 2012-10-15, 12:50, m

OK

systemtools  rootsettings on cisco

OK

This will kick you out of the shell, so you need to relogin, but now as root and password cisco [or whatever password you choose after the keyword "on" above].

Remove those 2 files :

[dderidde-ex90-home:~] $ rm /user/noboot

[dderidde-ex90-home:~] $ rm /user/nostart

Reboot and all should work.

When I try to log in as admin I get the following

login: admin

tshell: Failed to connect to TAN

Thanks

After reload, I would hope the default root password in TE4.1.1 would be "" or TANDBERG. Can we try these. If that does not work, can I give you a call to try and enable root in different way?

Thanks!

The only other alternative I see is to break into u-boot when the system starts.

When the system starts you should see :

yaffs: Mounting /flash

yaffs: restored from checkpoint

Hit any key to stop autoboot:  0

Before this point enter a key so the booting stops. The system should give you a prompt like "snoopy#" or so.

Enter the command :

setenv othbootargs allowroot

and then do boot.

root should be allowed then as login so we can finally remove the files

/user/noboot

/user/nostart

This seem Cisco E20 application is still not ready (at least when you access system).

Do you see menu on E20 now?

Default password for admin access should be empty therefore you should able to access Cisco E20 application by using “admin” account without entering password.

If E20 is not up and running, can you post boot console log once again?
