Hi,
We installed a new ARM Development studio. And use it to debug the linux kernel. I followed "About debugging a Linux kernel" and "Configuring a connection to a Linux kernel" chapters to debug.
I can connect to CPU and stop it, step one instruction each time, but I can not set breakpoint. I got following messages when I set breakpoint
WARNING(CMD452-COR167): ! Breakpoint 11 has been pended! No compilation unit matching "path_to/linux_kernel/net/8021q/vlan.c" was found
Our target board was based on i.MX8qxp, the debugger is DSTREAM-ST
Thanks for your reply. I used the win 10 to install the Arm Development studio.
I used the existing source code to create project. The path to source code include upper letter and lower letter, after I modify it to use only lower letter, the issue was gone. I am not sure whether the issue only happen in windows or my PC.
Hi LeiThanks for letting us know that you resolved the problem.Problems with the case of filenames are common (and expected) when using Linux kernel on Windows. This are due to Windows not being able to differentiate between upper and lower case in filenames (e.g. foo.h versus foo.H), where Linux treats these as separate files.Stephen
