Buildroot 配置启动 GDB over ADB
Buildroot 配置
配置使能 gdb 主机程序配置 gdbserver 程序
这里选择 gdbserver 够用即可配置编译 buildroot 包带调试信息，如果 buildroot 有配置"strip target binaries"，那么不影响最终打包到 target 的包，仅影响 staging 目录，相当于 android 的 symbol 目录和最终目录。
启动 GDB over ADB
- 配置 ADB 端口转发
adb forward tcp:1337 tcp:1337
- 启动 GDB Server 程序在 adb shell 或者串口控制台执行
gdbserver :1337 --attach COM PID # COM是要执行的程序完整目录和参数，PID是进程ID # 或者gdbserver :1337 COM # 例如gdbserver :1337 /bin/busybox ls Process /bin/busybox created; pid = 633 Listening on port 1337 Remote debugging from host 127.0.0.1 Remote side has terminated connection. GDBserver will reopen the connection. Listening on port 1337 Remote debugging from host 127.0.0.1 bin lib32 proc tmp busybox.config linuxrc root udisk config lost+found run userdata data media sbin usr dev misc sdcard var etc mnt sys init oem system lib opt timestamp
