So after testing and looking at the base files for SPA112 in EPM I found the files generated by EPM for these devices in /tfptboot are being rejected by the ATAs (at least the several I have tried)
If replace the created file with the output of a configured device it does provision and accept the file.
The one thing I noticed in the xml files generated they are missing<?xml version="1.0"?>
at the top of the file.
I tried adding this via basefile editor but was not able to add it to the top of file. Is there a way for my to mod the template to have <?xml version="1.0"?> show up at the top of file? I think this would fix the issue of rehected xml files.
