sudo apt-get install DDD

2.  Create a hello.c

Compile hello.c by using armeb-unknown-linux-uclibcgnueabi-gcc.

armeb-unknown-linux-uclibcgnueabi-gcc -g hello.c -o hello



Put hello to Embedded System.

Type gdbserver 192.168.x.x:12345 happy on the Embedded System.



3. Using DDD tool to debug

DDD  happy

target remote 192.168.x.x:12345
