OpenOCD , test run
得知 有這個工具
是一個透過 jtagwriter 可以 debug的工具
原始網站
Open On-Chip Debugger
binary 下載位置下載下來是一個安裝執行檔
我自己裝在
D:\openocd-2007re204
取代原本的 c:\programfile底下
沒什麼太大的原因
只希望打開D:後
可以很快打開該目錄而已
form readme.txt
可以得知目前 support
This version of openocd supports the following ARM7/9 cores:
- ARM7TDMI(-s)
- ARM9TDMI
- ARM920t
- ARM922t
- ARM926ej-s
- ARM966e
- Cortex-M3
Support for Intel XScale CPUs is also included:
- PXA25x
- PXA27x
- IXP42x
cpu是 arm920t
試了

失敗
在try看看

是cfg 的設定呀：
-f .\configs\arm9_ft2232.cfg
要設成用printer port.
參考 "OpenOCD , test run"
拿arm9_ft2232.cfg來改
#interface
interface ft2232
ft2232_device_desc "Amontec JTAGkey A"
ft2232_layout "jtagkey"
ft2232_vid_pid 0x0403 0xcff8
jtag_speed 1
#use combined on interfaces or targets that can't set TRST/SRST separately
reset_config trst_and_srst
修改成
#interface
interface parport
parport_port 0x378
parport_cable sjf
jtag_speed 8
#use combined on interfaces or targets that can't set TRST/SRST separately
reset_config trst_and_srst
在run一次

charles makd source code 把 sjf加到jtag/parport.c
我把 sjf 拿掉

不行
不知道有沒有動態的方式
可以把 charles 處理好的 { "sjf", 0x80, 0x00, 0x04, 0x01, 0x02, 0x00, 0x00, 0x80, 0x00, 0x00, 0x00 } 給 dynamic 載入使用
charles說 我們的pin腳對應跟chameleon一樣
所以拿他的來用
從\bin\configs\chameleon.cfg的內容
改成
#daemon configuration
telnet_port 4444
gdb_port 3333
#interface
interface parport
parport_cable chameleon
jtag_speed 0
#jtag scan chain
# format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 5 0x01 0x1f 0x01
改成chares此篇文章
"openocd + arm-elf-insight"
修改成
#daemon configuration

parport_port 0x378

Info: openocd.c:93 main(): Open On-Chip Debugger (2007-09-05 09:00 CEST)
在修改期間
#use combined on interfaces or targets that can't set TRST/SRST separately
reset_config trst_and_srst #srst_pulls_trst
and
這個
#target configuration
daemon_startup attach
#target
target arm920t little reset_run 0 arm920t
#working_area 0 0x200000 0x4000 backup

還沒有加入之前
有出現過 some message

把轉板的switch撥給multi-ice用
而不給jtag用
