Building Bare-Metal ARM Systems with GNU: 10 part series

Extract:- The toolchain provides the ever-popular GDB for debugging low-level programs. When the program is targeted for a single-board computer with a JTAG or ICE unit attached, you can use the Sourcery G++ Lite debugger (gdb) to debug the ARM code remotely. If you wish to test the code as I did—on the Android Linux system running on a mobile phone—you need to attach the phone to the workstation using the USB cable that came with it, then use the Android software development kit’s (SDK’s) adb push command to transfer the program to the phone.
