LP-CC2652R7: How to develop openthread application after sdk7?

Part Number: LP-CC2652R7

Tool/software:

1. How to compile ot-ti library with TI Clang compiler? I tried to compile with TI Clang compiler but encountered many errors.

2. Openthreda is no longer integrated into SDK since SDK7, so how should I continue to develop my Openthreda application in subsequent versions?
