[英]Debugging arm-elf C code using Zylin in Eclipse CDT
I'm using Eclipse CDT with Zylin embedded debug (native) and arm-elf-gdb 6.6 on OS X 10.5.8. 我在OS X 10.5.8上使用带有Zylin嵌入式调试(本机)和arm-elf-gdb 6.6的Eclipse CDT。 I've got an OCD debugger connecting to a board with an ARM processor.
我有一个OCD调试器连接到带有ARM处理器的电路板。
Eclipse is able to stop at the first breakpoint and gather variables from memory, but any subsequent breakpoints or single-steps fail. Eclipse能够在第一个断点处停止并从内存中收集变量,但是任何后续断点或单步操作都会失败。 I can set breakpoints ok when using commandline gdb, but setting breakpoints at the exact same location gives me these errors in Eclipse:
我可以在使用命令行gdb时将断点设置为ok,但是在完全相同的位置设置断点会使我在Eclipse中出现以下错误:
Warning:
Cannot insert breakpoint 2.
Error accessing memory address 0x3f6: Unknown error: -1.
And my OCD connection dies with "Error: unexpected error -308"
并且我的OCD连接死于
"Error: unexpected error -308"
I'm using the same OCD script in both cases. 在两种情况下,我都使用相同的OCD脚本。
The only differences I see are (1) Eclipse uses Zylin and the mi protocol to talk to gdb, and (2) my gdb script is invoked differently in this way: 我看到的唯一区别是(1)Eclipse使用Zylin和mi协议与gdb进行通信,以及(2)我的gdb脚本以这种方式被不同地调用:
When running from gdb, I use a script file that ends with these two lines: 从gdb运行时,我使用以以下两行结尾的脚本文件:
load filename.out
symbol-file filename.out
In Eclipse, I copy the contents of this script file into "Debug Configurations | Commands" (I've tried both the "'Initialize' Commands" and "'Run' Commands" boxes. I replace the last two lines with load
, and specify filename.out
in the "Debug Configurations | Main | C/C++ Application" box. 在Eclipse中,我将此脚本文件的内容复制到“调试配置|命令”中(我已经尝试了“'Initialize'Commands”和“'Run'Commands”框。我用
load
替换最后两行,并在“调试配置|主| C / C ++应用程序”框中指定filename.out
。
I'd appreciate any suggestions about how to get Zylin+Eclipse to behave. 我将对有关如何使Zylin + Eclipse正常运行的任何建议表示感谢。 Thanks.
谢谢。
I'm using the same solution on a LPC2103. 我在LPC2103上使用相同的解决方案。
Go to Eclipse, in Zylin Debug Configurations > Embedded Debug (Native)
: 转到Eclipse,在
Zylin Debug Configurations > Embedded Debug (Native)
:
Main tab: C/C++ Application = you_elf_file.elf
主选项卡: C / C ++应用程序=
you_elf_file.elf
Debugger tab: GDB debugger = arm-elf-gdb
; 调试器标签: GDB debugger =
arm-elf-gdb
; GDB command set = Standard
; GDB命令集=
Standard
; Protocol = mi2
协议=
mi2
Commands: 命令:
'Initialize' commands: '初始化'命令:
target remote localhost:3333
monitor arm7_9 dcc_downloads enable
monitor arm7_9 fast_memory_access enable
monitor arm7_9 dbgrq enable
monitor reset halt
monitor wait_halt
monitor sleep 500
load
'Run' commands: “运行”命令:
continue
I'm using parallel port Wiggler and OpenOCD [Open On-Chip Debugger 0.4.0] with the cfgs that came with the installation: 我将并行端口Wiggler和OpenOCD [Open On-Chip Debugger 0.4.0]与安装随附的cfgs结合使用:
openocd -f interface/parport.cfg -f target/lpc2103.cfg
It works most of the time for me. 它对我大多数时间都有效。
