我有ST-LINK V2的「ARM微控制器最低系統開發板 - STM32F103C8T6」。 這是主要的代碼，接着再接頭 - 腳本啓動：主STM32F103C8T6復位後不工作按鈕

和LED不閃爍，但是當我第一次上傳使用ARDUINO IDE任何代碼（此板），然後我運行prevouis命令，led開始閃爍，但如果我按下了重置按鈕或拔下插頭，然後插上st-link，則LED停止閃爍。

所以我認爲問題是與我的鏈接器或啓動代碼，但我不知道它在哪裏。

啓動代碼或鏈接描述文件有什麼問題？

與你鏈接腳本，增加了Reset_Handler一個標誌，沒有做太多，因爲這不是從一個裝操作系統，但是從閃存（向量表定義的入口點不是小精靈，它沒有用於那種形式）

然後你可以添加更多的代碼讓它閃爍，我現在不打算挖出一個STM32F103，也許可以拼湊一些未經測試的東西。等着瞧。

您是否正在使用向量表的0x08000000地址在您的構建中的正確位置，看看如何以這種方式使用這些工具？

從您dissassembled文件的方式開始了好嗎

20000100 
08000161 
080001a1 
080001a1 
080001a1 
080001a1 
080001a1

，看起來合理的......我不知道，如果他們是正確的地址，但假設他們是

這是工作的C代碼對於相同的芯片，但銷PC13，而不是15

void PUT32 (unsigned int, unsigned int); 
unsigned int GET32 (unsigned int); 
void dummy (unsigned int); 

#define GPIOCBASE 0x40011000 
#define RCCBASE 0x40021000 

int notmain (void) 
{ 
    unsigned int ra; 
    unsigned int rx; 

    ra=GET32(RCCBASE+0x18); 
    ra|=1<<4; //enable port c 
    PUT32(RCCBASE+0x18,ra); 
    //config 
    ra=GET32(GPIOCBASE+0x04); 
    ra&=~(3<<20); //PC13 
    ra|=1<<20;  //PC13 
    ra&=~(3<<22); //PC13 
    ra|=0<<22;  //PC13 
    PUT32(GPIOCBASE+0x04,ra); 

    for(rx=0;;rx++) 
    { 
     PUT32(GPIOCBASE+0x10,1<<(13+0)); 
     for(ra=0;ra<200000;ra++) dummy(ra); 
     PUT32(GPIOCBASE+0x10,1<<(13+16)); 
     for(ra=0;ra<200000;ra++) dummy(ra); 
    } 
    return(0); 
}

我通過你的拆卸工作，揣摩你使用它們看上去是錯誤的，到目前爲止什麼地址， 0x40021014而不是0x40021018來啓用端口c。 （PUT32/GET32只是存儲/加載函數dummy僅僅返回，用於防止優化）

也我認爲你正在做一個商店來啓用端口，而不是一個讀 - 修改 - 寫？ –

stm32f103上的apb2enr位於0x40021018，它是位4，所以你很接近，我們可以假設它從零開始重新設置爲零，並且你不使用其他項目，所以只需要做一家商店即可。 –

您的CRH寫入看起來不錯，0x40011004 0x34444444 –
