自制PCB/KEIL MDK/JLINK裸奔F1C100S，一步一步填坑

用自制PCB，用KEIL MDK和JLINK裸奔调试F1C100S
填坑开始

第一坑 JLINK连接
第一坑拜晕哥所赐
如下图

如果只连图上4根线，那么调试时会出来如下提示，然后退出调试

连上地和电源到JLINK后，就能正常调试了

第二坑 下载

由于以前一直用的是有内部FLASH的，所以调试的第一步自然是下载
对于F1C100S没有内部FLASH的，下载自然是有问题的，JLINK信息如下

我知道需要下到SRAM或DRAM，但怎么下进去就不知道了
在参考了网友的例程，和网友晕哥和aozima的帮忙下，总算清楚了这个过程，填坑如下
1）在编译通过后，不需要download，直接开始debug就可以
2）如果要在SRAM中运行，那么project options需要设置如下
   A）Linker tab中的Scatter file和Misc controls分别设置如下

run_in_sram.sct文件代码如下

LR_IROM1 0x00000000  {    ; load region size_region
    ER_IROM1 0x00000000 {  ; load address = execution address
        *.o (F1C100S_INIT, +First)
        *(InRoot$$Sections)
        .ANY (+RO)
    }
    RW_RAM1 +0  {  ; RW_RAM1 start address is after ER_ROM1
        .ANY (+RW +ZI)
    }
}

  B）Debug tab中的Initialization File中设置如下

run_in_sram.ini代码如下

FUNC void SET_PC_SRAM(void)
{
	PC = 0x00000000;
}

SET_PC_SRAM();

  C）Utilities tab设置如下

如果要运行在DRAM中，那么设置如下：
   A）Linker tab中的Scatter file和Misc controls分别设置如下

run_in_dram.sct文件代码如下

LR_IROM1 0x80000000  {    ; load region size_region
    ER_IROM1 0x80000000 {  ; load address = execution address
        *.o (F1C100S_INIT, +First)
        *(InRoot$$Sections)
        .ANY (+RO)
    }
    RW_RAM1 +0  {  ; RW_RAM1 start address is after ER_ROM1
        .ANY (+RW +ZI)
    }
}

  B）Debug tab中的Initialization File中设置如下

run_in_sram.ini代码如下

FUNC void INIT_CLOCK(void)
{
	int val;
	
	//先把CPU时钟源设置为24Mhz晶振
	val = _RDWORD(0x01c20050);
	val &= ~(3 << 16);
	val |= (1 << 16);
	_WDWORD(0x01c20050, val);
	
	//设置PLL_PERIPH(N=25,M=1) to 600Mhz
	_WDWORD(0x01c20028, 0x80041800);

	//设置AHB/APB/HCLKC的工作频率 200MHz/100MHz
	_WDWORD(0x01c20054, 0x00003180);

	//开启DRAM的front-end和back-end的DCLK门
	_WDWORD(0x01c20100, 0x05000000);	

	//配置PLL_CPU的值408MHz
	_WDWORD(0x01c20000, 0x80001000);

	//把CPU时钟源设置为PLL_CPU
	val = _RDWORD(0x01c20050);
	val &= ~(3 << 16);
	val |= (2 << 16);
	_WDWORD(0x01c20050, val);	
}

FUNC void INIT_DRAM(void)
{
	int val;
	
	//初始化DRAM
	val = _RDWORD(0x01c20824);
	val |= (7 << 12);
	_WDWORD(0x01c20824, val);

	//设置DRAM时钟 156MHz
	_WDWORD(0x01c20020, 0x80100c00);

	//开启DRAM时钟
	val = _RDWORD(0x01c20060);
	val |= (1 << 14);
	_WDWORD(0x01c20060, val);	

	//DRAM软件复位失效
	val = _RDWORD(0x01c202c0);
	val |= (1 << 14);
	_WDWORD(0x01c202c0, val);				

	//设置DRAM参数
	_WDWORD(0x01c01000, 0x0001318a);	//f1c100s设置
	//_WDWORD(0x01c01000, 0x0001338a);	//f1c200s设置

	val = _RDWORD(0x01c0100c);
	val &= ~(7 << 6);
	val |= ((4 << 6) | (1 << 0));
	_WDWORD(0x01c0100c, val);			
}

FUNC void SET_PC_DRAM(void)
{
	PC = 0x80000000;
}

INIT_CLOCK();
INIT_DRAM();
SET_PC_DRAM();

现在能正常在SRAM和DRAM中调试了

在此感谢@晕哥和@aozima的帮助
