GDB can be used to examine the contents of memory and registers while executing a program,

thereby enabling one to debug a program. This is done by using gdb commands to

● Start executing program

● Stop or pause execution at specified conditions

● Examine the contents of registry or memory locations

● Alter contents or registry or memory location

For RISC-V 32 bit use

3. Specify the program to be debugged

4. Connect to remote target

5. Load the file to memory

6. Set breakpoints

9. Exit GDB
