STM32的SRAM调试

http://www.cnblogs.com/TrueElement/archive/2012/09/11/2680863.html

 据说Flash的擦写次数是有限的，所以在调试的时候擦来擦去不好，看到boot0、boot1可以配置从SRam启动，就查了相关资料，试了一下，ok了。记录一下，免得以后又忘了。跟flash调试部分相同的就不再描述了，重点在于SRam调试的设置部分，大部分以图片形式。

 

Dbg_RAM.ini（D:\Keil\ARM\Boards\Keil\MCBSTM32\Blinky下面有一个，其实MCBSTM32目录下的都一样的，只要有）的内容：

LOAD %L INCREMENTAL // load the application  Setup(); // Setup for Running  g, main

最后，BOOT0和BOOT1引脚都接到3.3v，从SRAM启动

JTAG调试，一切正常。
