Hi zhiyong,
Customer should download the FRDM-KEA Quick start package (REV 8 ) from FRDM-KEAZ128: KEA Freedom Evaluation Board.
But the FRDM-KEA Quick start package (REV 8 ) download from that link was broken at the moment. Maybe you can get this package from your colleague. He once download it from: How to download SDK for S9KEAZ64AMLH
You can refer this example: FRDM_KEA128_FTM_DualEdge

Best Regards,
Robin
