Hi Lixiang.
I received your private message so I answer you here.
I suggest you use KDS, this IDE supports Kinetis and it is free
Kinetis® Design Studio Integrated Development Environment (IDE)|NXP
NXP will release MCUXpresso which can support Kinetis too. but it is not released yet. Its first ‘download day’ is March 31st, with a general announcement on April 4th.
for more information, see
Have a great day,
Jennie Zhang
