From what I have read in other documents and posts, this page should provide the binary bootloader for this board:
I chose the TWR-K65 board and it gave a link to this file:
I dropped this onto the BOOTLOADER drive, USB-cycled the board, and it appears dead. No virtual COM port or any other new devices show up in Windows Device Manager. Forging ahead anyway, I tried initiating a debug session with KDS, following the instructions here:
The OpenOCD debugger is selected, as per the instructions here:
I get "OpenOCD failed with code(1)." The console messages are:

The document "Getting Started with Kinetis SDK (KSDK) v.2.0" says a Windows driver is required, gives a link which provides this driver: mbedWinSerial_16466.exe
This driver did not install because "no mbed microcontrollers were found".
I have previously used this board with the P&E OpenSDA debug interface. Hopefully I can restore it back to the board.
Is OpenSDAv2 available and working correctly for the TWR-K65 board? Is there something wrong with the file k20dx128_twr_k65f_if_0x8000.bin?
