hi every one
i wrote a c project for a stm32f103ret6 in keil & download it with jlink v8 to mcu ,it work fine.
but know i want to program same project to the stm32f103rbt6 but it dosent work correctly
i download the program by jlink & it successfully program the mcu, then i pulled down boot0(or not ) and reset mcu but mcu dosent work .
i used any other simple project but always result is same.
may i solve it with defining knew project for stm32f103rbt6?

hi 2a
know i can run gpio sample in knew mcu(old sample for stm32f103ret6 correctly run in knew stm32f103rbt6)
but i cant launch usart samples in knew mcu yet !!!
i use cmsis for usart(sample correctly work on my stm32f103ret6 mcu )
