Emulating with the STM32F030. Everything works good until I turn on the serial interrupt. After that if I step I find myself stuck in the serial interrupt. An external device is sending serial data to the STM32F030. I have tried creating a debug.ini file but that did not help. Is there a way around this? I am using the Keil system and I can step with serial interrupts in the STM32F107 and STM32F407.
