ST-LINK JTAG and bootloader [STM32F207]

Question asked by Wapers on Oct 17, 2013

We are developing a board with STM32F207 and we are planning to use ST-Link JTAG to download our programs to the internal memory flash of the uC and for debugging.

The first problem we have encountered are the BOOT 0-1 pins configuration, used to start the uC from Flash Memory or System Memory. Our assumption is that the ST-Link JTAG, once connected, takes control of the uC boot sequence, and, when disconnected, the boot sequence control returns to the uC.

Following this assumption, we would set Boot 1-0 to X-0 respectively in order to boot the uC from the flash memory when ST-Link is not connected.

The question is if this assumption is true, and in case it isn't, we would appreciate any help or directions on how to proceed regarding this matter.

Thanks in advance,
