I am already using stm32f030c8t6 in various projects. And for larger flash controller i decided to opt for stm32f030cct6.
when i read my target device having stm32f030cct6(printed on IC), it responds the message
16:21:42 : ST-LINK SN : 56FF73066772565605300567
16:21:42 : ST-LINK Firmware version : V2J21S4
16:21:42 : Connected via SWD.
16:21:42 : Connection mode : Normal.
16:21:42 : Device ID:0x442
16:21:42 : Device flash Size : 256KBytes
16:21:42 : Device family :STM32F09xx.
Please note the family(STM32F09xx) read from micro using st-link utility is different from printed part number(stm32f030cct6).
Now i am confused that which ic i am using and what are the feature of it. whether it belong to stm32f030xx family or stm32f09xx family.
Also difficult to decide which .asm file i should use, either startup_stm32f030.s or startup_stm32f091.s. Because both beth to different family and different peripherals also.
Please guide me asap.
