STM32的SRAM調試

      據說Flash的擦寫次數是有限的，所以在調試的時候擦來擦去不好，看到boot0、boot1可以配置從SRam啟動，就查了相關資料，試了一下，ok了。記錄一下，免得以后又忘了。跟flash調試部分相同的就不再描述了，重點在於SRam調試的設置部分，大部分以圖片形式。

 

Dbg_RAM.ini（D:\Keil\ARM\Boards\Keil\MCBSTM32\Blinky下面有一個，其實MCBSTM32目錄下的都一樣的，只要有）的內容：

 *----------------------------------------------------------------------------*/
FUNC void Setup (void) {
  SP = _RDWORD(0x20000000);          // Setup Stack Pointer
  PC = _RDWORD(0x20000004);          // Setup Program Counter
  _WDWORD(0xE000ED08, 0x20000000);   // Setup Vector Table Offset Register
}

LOAD %L INCREMENTAL                  // load the application

Setup();                             // Setup for Running

g, main

最后，BOOT0和BOOT1引腳都接到3.3v，從SRAM啟動

JTAG調試，一切正常。
