The petalinux-util gdb command is a wrapper
around the standard GNU GDB debugger and simply launches the GDB debugger in the current
terminal. Executing petalinux-util gdb --help at the
terminal prompt provides verbose GDB options that can be used.
For GDB GUI-based debugging, use the AMD Vitis™ software platform. For more information regarding GDB, see Vitis Unified Software Platform Documentation: Embedded Software Development (UG1400).
