Unplug the board, and now power it normally (without SW1 pressed).Wait a few seconds to complete the operation. The device should enumerate BOOTLOADER: device on your host.Power the board/Plug in the USB cable with the OpenSDA USB port, while having the Reset/SW1 pressed.Unzip the firmware file (JLink-OpenSDA_v2_1.bin) in the zip file to your harddisk.
You need to install the Segger J-Link OpenSDAv2.1 firmware on the board, and you only need to do this once (unless you change the firmware again). Installation of Segger J-Link OpenSDA V2.1 Firmware (Another solution is to use the P&E Multilink OpenSDAv2.1 firmware, see FRDM-K22F: Debugging with P&E OpenSDAv2.1 Firmware) One solution is to use the Segger J-Link OpenSDAv2.1 firmware to debug the board. Trying to debug the FRDM-K22F board with KDS V1.1.0 and OpenOCD/CMSIS-DAP results in an error in the Console View and is currently not possible, until OpenSDA gets updated (see Kinetis Design Studio V1.1.0: Release Notes and News). OpenOCD with CMSIS-DAP for FRDM-K22F is not supported in KDS V1.1.0. (see 'Technical Details' at the end about the OpenSDA differences) The FRDM-K22F board ( FRDM-K22F|Freedom Development Board|Kinetis|Freescale) comes with OpenSDAv2.1 programmed on it, and has the CMSIS-DAP debug firmware on it by default. This document explains how you can debug the FRDM-K22F board with the Segger J-Link OpenSDAv2.1 Firmware and the Kinetis Design Studio V1.1.0.
