关于IAR用JLINK调试的疑问

xiaojian1227 2012-03-19 08:40:49

这几天在用IAR和JLINK调试ARM9的一个测试程序,刚接触ARM一个月了,还没有吃透如何下载程序,以及程序在目标板执行的过程,一下是我IAR调试过程中出现的调试信息:

Mon Mar 19 20:35:01 2012: Failed to read one or more register values (busy).
想请问一下大家,当中出现的RTCK is not connected是怎么回事呢?以及最后一句Failed to read one or more register values (busy).也不知道是什么原因,我的linker的配置文件中的内容如下:
/*###ICF### Section handled by ICF editor, don't touch! ****/

define memory mem with size = 4G;

define block FIQ_STACK with alignment = 8, size = __ICFEDIT_size_fiqstack__ { };
define block UND_STACK with alignment = 8, size = __ICFEDIT_size_undstack__ { };
define block ABT_STACK with alignment = 8, size = __ICFEDIT_size_abtstack__ { };
define block HEAP with alignment = 8, size = __ICFEDIT_size_heap__ { };

initialize by copy { readwrite };
do not initialize { section .noinit };

place at address mem:__ICFEDIT_intvec_start__ { readonly section .intvec };

place in ROM_region { readonly };
place in RAM_region { readwrite,
block CSTACK, block SVC_STACK, block IRQ_STACK, block FIQ_STACK,
block UND_STACK, block ABT_STACK, block HEAP };
主程序如下:
#include "Def.h"
#include "Option.h"
#include "2440addr.h"
#include "2440lib.h"
#include "2440slib.h"
#define led0_on (rGPBDAT &= ~0x01)
#define led0_off (rGPBDAT |= 0x01)
//================================
void delay(U32 tt)
{
U32 i;
for(;tt>0;tt--)
{
for(i=0;i<10000;i++){}
}
}

int main(int argc, char **argv)
{
//mpll_val = (92<<12)|(1<<4)|(1);
//init FCLK=400M, so change MPLL first
//ChangeMPllValue((mpll_val>>12)&0xff, (mpll_val>>4)&0x3f, mpll_val&3);
//ChangeClockDivider(key, 12);

//ChangeClockDivider(1,1); // 1:2:4 FCLK:HCLK:PCLK
// rCLKDIVN=0x4; // 1:4:4
//ChangeMPllValue(82,2,1); //FCLK=135.0Mhz

while(1)
{
led0_on;
delay(0xfffff);
led0_off;
delay(0xfffff);
}
} 希望大家能多给些建议及指导!
