TSM320F2812 烧写到Flash中的configuration 问题总结

?首先从网上查阅的资料，都说比较困难。实着对我这样的业余2812人员一个大大的下马威啊。没有办法，饭只有一口一口的吃。摸索下来，发现也不是很困难的事情啊（也许在下是夜郎自大，没有遇到稀奇古怪的case）。

????????? place-lower device只是实现了很简单的功能，
?????????? 1，eCan,采用了poll transmit AND interrupt receipt,
?????????? 2，SCI -b,同样采用轮训发送，中断的接收；
?????????? 3，ADC ，只采样了三路，做了很基本的Float到Hexadecimal 的转换
????????? ADC采样数据发送到eCan interface，pc端只有一个eCan <<==>>USB的adapter《==》virual COM。没有软件，没有开发库（由于我们前期只是把功能实现了），连用多少Baud，数据位，停止位是什么都不知道，费劲吧；在这上面,确实花费我不少的功夫，读出USB的original 数据啊，查找其rule（都是凑出来的），然后解码成原始发送的数据，丢到VC的GUI中显示波形。
??????? ok，言归正传，先修改cmd文件，我的cmd文件如下 MYF2812.cmd（CMD文件的格式，讲的地方很多，google一下吧）

,需要注意的是，出现 warning: creating output section XXXXXXXXX without SECTIONS specification 的警告时，标示您的cmd文件中找不到xxxxxx指定的节，必须要加它。
千万不要忘记flash 的初始化，如果能顺利的进入startbranch.asm中的话，http://tiyubisai.com/video_news/news_135564.html ?而在illegalISR中等待，则很可能是initflash函数没有执行，这个函数需要再SRAM中执行，所以要先把它move到RAM中，然后在run，如下
?? MemCopy(&RamfuncsLoadStart,&RamfuncsLoadEnd,&RamfuncsRunStart);
????
// Call Flash Initialization to setup flash waitstates
// This function must reside in RAM
?? InitFlash();

?在flash中运行的程序也是可以调试的，这时候的step into （F10），Step over（F11）已经基本不用了。而用assembly step-into 和assembly step-over来替代
