昨天发现了这个帖子http://www.amobbs.com/forum.php?mod=viewthread&tid=5565886，心里开始长草，虽然还没有开发，但想要先升级一下板子的openSDA固件。
结果发现按照方法升级之后，遇到了一个问题，拷入的固件消失了，但是插入设备后总是显示bootloader，而且网页上看版本号没有升级。
这到底是为什么呢百思不得其解，晚上换了台机器也不能解决问题。

后来在openSDA网站上乱翻，发现了FAQ中有解答,链接“：http://www.pemicro.com/opensda/faqs/faqs.cfm：
Issue:  Bootloader versions 1.10 and earlier are not allowing firmware update and MSD FLASH programming on my OpenSDA board, with the Linux, MacOS or Windows 8/8.1 operating systems.


Solution: Support for Windows 8/8.1, MacOS and Linux operating systems was added to Bootloader version 1.11 and MSD firmware version 1.14. Please make sure that your board is programmed with Bootloader version 1.11 or higher prior to attempting to update your OpenSDA board with a new firmware application.
Important: If you are currently running Bootloader version 1.10 or earlier, you will need to find a Windows XP or Windows 7 PC to perform this update.
Please follow these steps to find out what version of Bootloader your board is programmed with: 1.Start your board in Bootloader mode by holding down the RESET button prior to plugging it into USB port.
2.Open the SDA_INFO.HTM file, which will contain version numbers of Bootloader as well name and version of current OpenSDA firmware you are using. If your board is not running Bootloader version 1.11 or higher, please download the latest OpenSDA Firmware Apps from P&E website and follow instructions in corresponding documentation to update the Bootloader using the BOOTUPDATEAPP_Pemicro_v111.SDA application. Once the Bootloader is updated via BOOTUPDATEAPP, the OpenSDA board can then be upgraded to the latest combined MSD/DEBUG OpenSDA firmware 1.14 or greater.

原来是需要一台winXP，win7的机器，才能成功升级，升级之后，win8才能用……
郁闷了一天，希望大家能不要走我的弯路。
