Suppose there is a project folder /home/srcdbg/project/module_prj in the WSL ubuntu18 whose host name is localhost. PC is at hello_init+0x24/0x38 [test] when the linux kernel crashes. Here are steps to create a new project to locate the crash position of the source code.

Segmentation fault
2. Select File > New > Solution... > Wizard... and then click the OK button.
3. Enter the name of the project and click Next button.
4. Enter the correct Remote host, Port, Username, Password, Initial path and click Next button.
5. Click Next button.
6. Click Next button.
7. Click Finish button.
8. Enter the solution File name and click Save button.
9. Enter the project File name and click Save button.
10. Right click the srcdbg_test project and select Add > Add Existing Remote File to add the project files.
11. Select the needed folders and files and click Open button.
12. Select Build > Synchronize Files... to synchronize files and build the project symbols.
13. Right click the linux_module_test project and select Properties.
Change Attach to program as "-i=mi ./test.ko".
Configure Entry function as "hello_init".
14. Select Debug > Start Debugging to debug the project.
15. Input "hello_init+0x24" in the find box 
and press Ctrl+J to jump to the source code.
16. It will automatically navigate to the corresponding location of the crash in the source code as below.
17. If you want to use relocation addresses for offline code analysis, you can execute the following command on the arm board:
# cat /sys/module/test/sections/.init.text
0xbf019000
# cat /sys/module/test/sections/.exit.text
0xbf017000
Then right click the linux_module_test project and select Properties:
Configure Attach to program as "-i=mi".
Configure Entry function as "hello_init".
Configure Postdebug command as "add-symbol-file /home/srcdbg/project/module_prj/test.ko -s .init.text 0xbf019000 -s .exit.text 0xbf017000".
Then you can use the relocation address (e.g. 0xbf019024) for offline code debugging in a similar way as above.
