I used STM32F103 MCU before and was new for STM32F3x MCU. My stm32f103 codes was migrated  to stm32f302 codes for stm32f302r8 MCU. The code problem is that after power on, MCU turned on LED normally and printed out "0123456789" only (full string should be '1234567890'), and then got stuck. Attached please find my stm32f302 codes. Can anyone expert help me to fix this issue? Thanks in advance.
