[GDB] How to use gdbserver

1. Upload gdbserver to Embedded Board
2. Create a c file

#include <stdio.h>
//This function will cause "Segmentation fault"
void memory_violation()
{
    char* ptr = 0;
    for(int i=0; i<10; ++i)
    {
        ptr[i] = i;
    }
}

int main(int argc, char* argv[])
{
    memory_violation();
    return 0;
}



compile it.
-ggdb create symbol.
armeb-unknown-linux-uclibcgnueabi-gcc -ggdb -std=gnu99 -o hello hello.c



3. Upload program && Execute the gdbserver

./gdbserver “embedded ip”:”embedded port” “program”
./gdbserver 111.6.1.191:12345 ./hello



4. On the Local Machine

./armeb-linux-gdb ./hello
When see (gdb), the type
target extended-remote 111.6.1.191:12345
Type run will see result appear on Embedded board

PS. Still can use ddd, but no working.
ddd –debugger /tmp/happy1/bin/armeb-linux-gdb /tmp/test2/hello –eval-command=”target extended-remote 111.6.1.191:12345”
