Display HLL C when debugging Linux kernel source with TRACE32

I am debugging with Linux kernel LTS4.4 (arm32, cortexa7).
I already built successfully the kernel image as well as vmlinux.
I am using Debugger Lauterbach and Trace32 tool.
And use below command to load vmlinux and kernel source
B:: data.load.Elf /home/compile-kernel/linux-4.4.138/vmlinux /PlusVM /STRIPPART 4 /PATH "/home/src-kernel"
The loading progress is successful, but I don't see any C code (HLL), only asm.
After that, I try to show symbol.list.source
. However, the table List is empty.
Could you guys support me on this ! Thanks.

Are you sure that you've build the kernel with debug information?

Yes. To be able to do Linux aware debugging, the vmlinux file must be compiled with debug info enabled. Thus, need to ensure that CONFIG_DEBUG_INFO is enabled in the kernel configuration. Probably find this option under “Kernel hacking -> Compile the kernel with debug info” (in newer kernel versions under “Kernel hacking -> Compile-time checks and compiler options -> Compile the kernel with debug info”). Make sure that CONFIG_DEBUG_INFO_REDUCED is not set (Reduce debugging information).

Well, if sYmbol.List.SOURCE is showing you an empty window, you are probably still missing required debug information in your vmlinux file. A suitable vmlinux file should be about 10 times bigger the raw image file. In you screenshot TRACE32 is still loading the file (there is the orange progress bar a the bottom) Have you waited long enough?

Hi Holger, of course I have waited for the progress completed. I just took the picture randomly for example.
