CCSv4: Debugging Linux on OMAP3430 (ARM Cortex A8)

Hi, I was trying to debug Linux using CCSv4 on the Zoom2. I was able to use CCS v3.3 to load the x-loader and the u-boot and step through the code. Unfortunately, when the u-boot passes control to the kernel, CCS doesn't know what's going on.

From what I understand after reading this article: http://tiexpressdsp.com/index.php?title=Linux_Aware_Debug is that CCS v4 is Linux aware.

Has anyone been able to successfully use CCS v4 to load the boatloader and the kernel using CCS and debug?

    Hi Christina,

    You can use CCS v4 to debug the kernel start up.

    First, you have to build your kernel with debug info (set CONFIG_DEBUG_INFO=y in .config).

    This ensures that the generated vmlinux file contains the kernel symbol information

    Before the u-boot passes control to the kernel, you have to load the vmlinux symbol file on cortex A8.

    Set a breakpoint at start_kernel or the kernel entry routine.

    Resume the target and the target should stop at start_kernel.

    Regards,
