Hi Don,
K70 and K61 120 and 150MHz devices are not on the roadmap for support within KSDK.
Here is a link to see available devices and roadmap of support for the KSDK_v2 release.
Introducing Kinetis SDK v2
To date the plan is to retain the CodeWarrior/IAR/Keil support for those mature (not dying) products. MQX4.2 also has the support for K70/K61.
Regards,
David
