Hi STM32 Users,

I am new in this MCU.
I am designing a board using STM32F101RE and but no external flash memory.
So, I want to boot from the inside internal flash memory in MCU.

1) Just want to know if boot from the inside internal flash memory.
What configure for Boot 0 and Boot 1 ?

2) In case I have a external flash memory installed, how can the MCU determine boot from internal or external flash memory ?

Thanks!

For booting from the inside flash : boot0 = 0, boot 1 = 1.

I don't think that STM32 is able to boot from external flash. Take a look at "2.4 Boot configuration" in the Reference Manual (RM0008).
For managing external memory the FSMC peripheral has to be configured, so a minimum of internal memory code has to be used.
