I imported the source used in 2.3.
When you build, the build will run normally without errors.
After connecting to the device, the icon will be created on the device.
The problem is that when you run the icon on your device, the program will not run.
When I run debug mode in the compiler, an error message is displayed as shown in the figure.
"Cannot launch application with GDBClient.
Error in final launch sequence
Failed to execute MI command:
-target-select remote 127.0.0.1:26104
Error message from debugger back end:
Remote communication error. Target disconnected.: No error.
Remote communication error. Target disconnected.: No error."
What is the problem and how should I find it?
