A customer had struggled with FastRTS on the OMAP-L138 and updated to MATHLIB. Good thing as it seemed to resolve many issues.
What ever happened to FASTRTS?
The below WIKI link (shipped in the FASTRTS README) appears to be dead.

However, the below is active although I can't seem to find the www.ti.com landing page for it.
Were there SysBIOS versioning issues with FASTMATH?
