关于JLink联接S3C6410的简单笔记

Andrew Haung

 

 

一.第一次调试

---------------------------------------------------------------------

1.S3C6410的ARM内核型号是:ARM1176JZF-S.看其J-Link V7文档是支持这个型号的:

 

1.4 Supported CPU cores
J-Link / J-Trace has been tested with the  following cores, but should work with any
ARM7/9/11 and Cortex-M0/M1/M3 core. If you experience problems with a particular
core, do not hesitate to contact Segger.
ï ARM7TDMI (Rev 1)
ï ARM7TDMI (Rev 3)
ï ARM7TDMI-S (Rev 4)
ï ARM720T
ï ARM920T
ï ARM922T
ï ARM926EJ-S
ï ARM946E-S
ï ARM966E-S
ï ARM1136JF-S
ï ARM1136J-S
ï ARM1156T2-S
ï ARM1156T2F-S
ï ARM1176JZ-S
ï ARM1176JZF
ï ARM1176JZF-S
ïCortex-M0
ïCortex-M1
ïCortex-M3

2.网上显示成功的是用JLink V8的成功，但是这个太贵了。

   或者用新版本的OpenJtag.也要近200大元

   成功的人提示驱动是 4.10i的.4.14驱动会出错。

 

3.用10pin的小型接头去接S3C2410.

用V7版本显示可以联J-Link.但是J-Link与target的通讯失败.

对比一个正常启动的LOG,启动时必须要找到ID

难到真要换JLink V8? 还是使用D版的JLink V7的硬件有问题? 这个要下一步分析

后来看这一篇文章，发现需要调整mini6410拉高。把R31的电阻焊到R37.

就看后续的MINI6410是否调整的设计了。

 

 

 

第二次调试(成功）

----------------------------------------------------------------------

 

以下部分转自

 

 

  S3C6410的文档中我们也可以得到XDBGSEL拉低用来调试内核，拉高用来调试外设。所以我们用仿真器调试的话应该是拉低。之前以为mini6410没有提供RTCK信号不能调试，后来经过测试发现，只要在Jlink驱动中不选择自适应模式就没有问题。因为这个信号是为了自适应而设计的，目的是使调试更稳定，既然mini6410没有提供这个信号，我们就可以选择其他方式，

 

 

 

 

以下硬件改动由梁熠章完成

重新用J-Link V7联接,可以看到CPU ID表示可以联接上.

 

 

由此证明V7还是能调试ARM11的开发板的.
