I'm using STM32F030 in my project. I'm using UART2 with Tx and Rx interrupts. While debugging, it works well but when i work it standalone, it stops before transmitting data and microcontroller probably stops. I observed the Tx line in standalone mode and couldn't see any data while it sends the data in debug mode. What may cause this problem.
