I am working on stm32f205RBT. I have an IAP loader from ST from EVAL board that I made my adjustment. Loader works great on other devices with other adjustments. program goes to main after the loader like it should and works good until I'm trying to communicate with UART. The problem that appears is that it get into some endless loop written in the end of startup.s file after all interrupt lists and before User Stack and Heap initialization. I have never seen program reached this area, does anyone have any idea what is this? What may cause this? and how can I solve it?
Thanks in advance.
