调试已在目标上运行的程序 - 2023.2 简体中文

赛灵思系统调试器命令行接口 (XSDB) 可用于调试已在目标上运行的程序（例如，从闪存启动）。连接到目标，并为目标上运行的程序设置符号文件。此方法也可用于调试从闪存启动的 Linux 内核。为了达成最佳结果，目标上运行的代码应使用调试信息进行编译。

以下是调试已在目标上运行的程序的示例。为便于演示，在此示例会话前，程序已停止于 main()。

# Connect to the hw_server

xsdb% conn -url TCP:xhdbfarmc7:3121
tcfchan#0
xsdb% Info: Arm Cortex-A9 MPCore #0 (target 2) Stopped at 0x1005a4 (Hardware Breakpoint)
xsdb% Info: Arm Cortex-A9 MPCore #1 (target 3) Stopped at 0xfffffe18 (Suspended)

# Select the target on which the program is running and specify the symbol file using the 
# memmap command

xsdb% targets 2
xsdb% memmap -file dhrystone/Debug/dhrystone.elf

# When the symbol file is specified, the debugger maps the code on the target to the symbol 
# file. bt command can be used to see the back trace. Further debug is possible, as shown in 
# the first example

xsdb% bt
    0  0x1005a4 main(): ../src/dhry_1.c, line 79
    1  0x1022d8 _start()+88
