Hi,
I executed the file program_JLINK.cmd and retry the debug function and got new ERROR.
***
Program file does not exist

If clean and rebuild the project, there is no .axf file in "Binaries" ...

I deleted the workspaces and imported all files from the SW297845.zip and got new problem ...

Update: 18.10.2017 - 11:08
I did reinstall IDE and restart the PC, I could build the projects again, but I got the same Error as yesterday
