Hello, we want to create a Keil project, in which we want to use the UART. When we want to debug our program the debugger jumps into the reset handler and stops. We tried to find out what the problem is. We found out it's only the problem, if we use printf. It's maybe necessary to take some settings in Keil uVision5, but we don't know what. We hope you can help us. Thanks!
Hello Jonas,
You might try searching the Keil knowledge base for ideas.
