You might encounter the following problems when debugging a Linux application.
ARM Linux permission problemIf you receive a permission denied error message when starting an application on the target then you might have to change the execute permissions on the application. :
chmod +x myImage
You must ensure that the application and shared libraries on your target are the same as those on your host. The code layout must be identical, but the application and shared libraries on your target do not require debug information.
When Operating System (OS) support is required, the debugger activates it automatically where possible. If OS support is required but cannot be activated, the debugger produces an error. :
ERROR(CMD16-LKN36): ! Failed to load image "gator.ko" ! Unable to parse module because the operating system support is not active
OS support cannot be activated if:
debug information in the
vmlinuxfile does not correctly match the data structures in the kernel running on the targetit is manually disabled by using the set os enabled off command.
To determine whether the kernel versions match:
stop the target after loading the
vmlinuximageenter the print init_nsproxy.uts_ns->name command
verify that the
