1：BOOTUPDATEAPP with Bootloader v1.11 fixes Added Windows 8.1 support；
2：MSD - DEBUG version 1.14 增加了 Windows8.1 系统的支持
- Added combined MSD, DEBUG and CDC virtual serial support in a single APP.
Switching between MSD and DEBUG apps is no longer necessary
- Added Windows 8.1 support.
OpenSDA 固件程序升到了版本 1.14
将 MSD 、 DEBUG 、 CDC 虚拟串口合为一体（以后使用 MSD 或 DEBUG 不再需要进入 Bootloader 切换了） 增加了 Windows8.1 系统的支持
详细操作：
一、安装 PE驱动程序，进入 PEmicro：http://www.pemicro.com/opensda/
Download PEDrivers_install.exe for manual install.
如果安装了：
Kinetis Design Studio installer for Microsoft Windows
或者
Kinetis Design Studio installer for Linux 64-bit RPM 3.0.0
就不需要安装 PE驱动了，强烈建议安装 Kinetis套件
二、下载固件程序，进入 PEmicro ：http://www.pemicro.com/opensda/
下载 Firmware Apps (.zip file).
三、解压缩后可以看到如下图示： BOOTUPDATEAPP 说明、 Bootloader 升级包、 OpenSDA 说明、 1.14 版的各板 OpenSDA 固件程序
四、更新 Bootloader ，请先读 BOOTUPDATEAPP_release_notes 并按如下步骤操作：
To update Bootloader please follow these steps:
1. Enter bootloader mode (generally by holding down the target reset button on the OpenSDA board and plugging in the USB connection).
2. Drag and drop the BOOTUPDATEAPP.SDA file to the root directory of the Bootloader "drive".
即OpenSDA_Bootloader_Update_App_v111_2013_12_11压缩包内的BOOTUPDATEAPP_Pemicro_v111.SDA
3. Unplug and replug your OpenSDA board to initiate Bootloader update. Bootloader update should take less than 15 seconds (probably averages 3 seconds).
4. Once update is complete, OpenSDA will automatically enumerate in Bootloader mode and green status LED will go on blinking with .5 second on/off intervals.
5. Run the SDA_INFO.HTM file in the root directory of the Bootloader "drive".
IMPORTANT: Please do not unplug OpenSDA while Bootloader is updating.
即可从网页上看到开发板 Bootloader已经升级到了1.11（参见下图）
五、继续更新Application Version：
Copy & paste or drag & drop the v 1.14 OpenSDA firmware applications （MSD-DEBUG-FRDM-KE02Z_Pemicro_v114.SDA ）into Bootloader disk / removable storage drive/OpenSDA board;
六、 Unplug and replug your OpenSDA board，It will appear as a removable storage drive with a volume label of FRDM-KE02Z. The Freedom Board is now updated to the latest firmware and application
（该状态就是可以Deubg，也可以往里丢.srec文件的OpenSDA最新状态）
七、 Run the SDA_INFO.HTM file in the root directory of the Bootloader "drive"
即可从网页上看到开发板 OpenSDA 的 Application Version已经升级到了 1.14 （参见下图）
在完成以上步骤后，若想从 OpenSDA 的 debug 、 MSD 模式切换，将不再需要进入 Bootloader 选择放入 Debug 还是 MSD 固件程序了。
