I am attempting to develop an application for a Raspberry Pi that uses the serial port. My development environment is based on VisualGDB and VS2019 and the target Linux distro is the latest 32 bit Raspian Linux (2020-08-20). To use the serial port I have had to stop Linux from taking possession of the port by disabling the serial console in the Raspberry Pi configuration. The problem I have after disabling the serial console is that I am unable to run the application (via GDB anyway) and attempting to do so results in the attached error window. I don’t understand the connection between VisualGDB and the serial console, is there a configuration option to fix this issue?
Hi,
This looks like the temporary directory where the project was built got deleted after a restart. Please try rebuilding the project and you should be able to debug it again.
Thankyou, that was indeed the case, but I don’t understand why the folder should have been deleted, but then it was in the temp folder so I guess it is valid. On that basis, I noticed that in the VisualGDB project settings the project directory can be specifically specified, however I tried to move it into the Home folder, and other folders, but I cannot get any other folder to work except the one in the tmp directory. Is there something else I have to do to move the project folder out of the tmp directory?
