Getting Started with Linux Kernel and Driver Debugging
The ARM DS-5 Altera Edition provides very powerful Linux Kernel and Driver debugging capabilities.
This section presents an example on of how to debug the Linux kernel and drivers using DS-5. The
software engineers can use the dedicated Linux debugging features presented in this section together with
the basic debugging features such as viewing registers, inspecting variables and setting breakpoints.
Note: In the scenario presented here the Linux kernel is already running on the board, but it can also be
downloaded through the debugger.
Note: This scenario uses the pre-built Linux images and Linux source code included in the SoC EDS.
These are examples only; use the latest sources from the Rocketboards website for development.
Note: This section uses a Linux host computer, as can be seen from the screenshots and the issued
commands. However, the scenario can also be run on a Windows machine, although it is not usual
for Linux development to be done on Windows.
Note: The paths presented in this section assume the default installation paths were used. Adjust
accordingly if non-standard location is used.

Linux Kernel and Driver Debugging Prerequisites
• Make sure the desired Linux kernel version is already running on the board. See the Getting Started
with Running Linux section for instructions on how to run the provided Linux binaries on the board.
• Make sure the Linux kernel executable file is accessible on the host computer. The kernel executable
for the pre-built Linux image is located at
<SoC EDS installation directory>/embeddedsw/socfpga/prebuilt_
images/vmlinux
.
• Make sure the source code corresponding to the kernel running on the board are accessible on the host
computer. The sources for the pre-built Linux image can be obtained by:
