This project contains unresolved buildable linked resources. It might not build as expected.

yes, thank you.  I think I understand the message.

but...how do I find the "unresolved buildable linked resource" CCS is referring to?

If you look at the files in the Project Explorer, you should see some files highlighted with the "!" icon. These files are files with broken links.

To see what linked resource variable these files rely on - if you look at slide 80 of the pdf I referenced, it shows you where you can look at all the linked files in your project and you can see which ones are dependent variables. In slide 80, all four files use the variable 'AM35xx_BSL_ROOT'.

Thank you. 

I found the yellow icon - it was on a ccxml target file.

The error should not be "'buildable linked resource", rather it should just say "linked resource". Unless I missed something...is a ccxml file 'buildable'?

You are correct. A ccxml files is not a source file that is built. But it appears as a warning and not an error, correct?
