Upgrade UC520 CUE-AIM to CUE 3.0.3 version

Unanswered Question
May 20th, 2008

When attempting to do a clean install of CUE 3.0.3 on my UC520 box i get the following error:

- Checking Package dependencies…Service Engine Bootloader can not be installed on this platform/chassis combination.

Does anybody know what this means and how to fix?

Thanks in advance

I have this problem too.

It means the UC520 does not accept generic CUE images.

This was when booting a tftp booloader after ***, right ?

What happens if you try a "software install clean" ?

Yes you are mostly correct.

This happened after a software install clean.

I tried the boot loader thing and got an error; something like bad magic number then reloaded of flash and got a blue prompt.

How do i get the updated CUE 3.0 and later on my UC520?

Thanks again.

Hmmm...that looks very promising.

No I didn't know they had special CUE files for the UC520.

Thanks greatly!! I'll give it a try.

Is there an installation guide available somewhere?
