project : debugging with Jlink on keil
instuction: jlinker settings for QQ2440 board under keil IDE
(1) Firstly, modify the scatter files as following( locate it start at SDRAM: 0x30000000):
scatter file:
; *************************************************************
; *** Scatter-Loading Description File generated by uVision ***
; *************************************************************
LR_ROM1 0x30000000 { ; load region size_region
RO +0 { ; load address = execution address
2440init.o (+RO,+First)
*(InRoot$$Sections)
.ANY (+RO)
}
RW +0 { ; RW data
.ANY (+RW)
}
ZI +0 { ; ZI data
.ANY (+ZI)
}
}
=================================================================
(2) Do not enable the item "Run to main()", because when the target reset, the PC value is 0x00000000, so will change it to 0x30000000 to run.(if not, it can not change the PC register value.)
(3) enter into "SEGGER J-Link RDI V4.02 Congiuration" Dialog and setting as below.
(3.1) General page: USB --> Device 0
(3.2) Init page: macro file as following:
filename: QQ2440.setup:

(3.5) Breakpoints page: Enable Use software breakpoints.
(3.6) CPU page: Enable Allow instruction set simulation, Little endian. Reset Normal.
(3.7) Log page: None.
4. ADS中J-Link设定
把S3C2440.setup解压后放到D:\sw\SEGGER\JLinkARM_V402\Samples\RDI\SetupFiles目录里，
在AXD的Options->Config Target ... -> 选中 JLinkRDI.dll -> Configure -> J-Link RDI V4.02 Configuration对话框中选中 Init属性页 -> use Macro file 中把S3C2440.setup文件选中，然后就可以在ADS中使用J-Link调试了。
