FRDM-K64F is an ultra-low-cost development platform for Kinetis K64, K63, and K24 MCUs. this board is already widely used among Freescale customers.
The FRDM-K64F platform features OpenSDAv2, the Freescale open source hardware embedded serial and debug adapter running an open source bootloader. This circuit offers several options for serial communication, flash programming, and run-control debugging. User who works with KDS3.0 can choose J-Link interface, P&E OpenSDA interface, or Mbed interface. For each of the option, user need update debugger firmware first. I will introduce each of them one by one.
All the related driver and firmware are enclosed in this article as attachment.
