저는 beaglebone black용 애플리케이션을 개발 중입니다. arm gcc 컴파일러를 사용하여 크로스 컴파일한 다음 scp명령을 사용하여 컴파일된 바이너리를 beaglebone black으로 포팅하고 보드에서 실행합니다.
애플리케이션은 한동안 완벽하게 실행 중이었는데 나중에 분할 오류가 발생했습니다. 몇 가지 조사를 한 후 디버깅을 사용할 수 있다는 것을 알았지 만 보드에 설치하는 방법이나 호스트 시스템을 사용하여 디버깅하는 다른 방법이 무엇인지 gdb문제에 직면했습니다 .gdbgdbserver
분할 오류를 디버그하도록 도와주세요.
답변1
먼저, cross-gdb가 필요합니다. 이렇게 하려면 gdb 소스 코드를 다운로드하고 압축을 풀고 실행한 ./configure --target=arm-linux-gnueabi다음 평소대로 진행하세요 make; make install. 이제 설치가 완료되었을 것입니다 gdb-linux-gnueabi. 달리다. beaglebone에서 실행합니다 gdbserver 0.0.0.0:1234. cross-gdb를 실행하는 머신에서 target remote 192.168.12.34:1234BBB의 IP 주소로 대체하는 명령을 입력합니다. 이제 평소처럼 gdb 세션을 사용할 수 있습니다.
그러나 몇 가지 주의 사항이 있습니다.
- 프로세스를 시작하려고 하지 말고 대신 "continue"(또는 "c") 명령을 사용하십시오.
- 디버깅 중인 프로세스를 종료하면
gdbserver종료됩니다. 다른 세션을 실행하려면 다시 시작하면 됩니다. gdb는 중단점 등을 기억합니다. 그러나target remote명령을 다시 실행 해야 합니다 . - Gdbserver는 디버깅된 프로그램의 이미지를 gdb로 보내지 않습니다. 이를 직접 수행해야 합니다. 개인적으로 가장 쉬운 방법은 NFS를 사용하는 것이라고 생각합니다.
