target is connected to the STLINK-V3SET before the STLINK-V3SET is plugged into the
host. This functionality is not available for STM8 targets.
The ST-LINK firmware programs the dropped binary file, at the beginning of the flash, only if
it is detected as a valid STM32 application according to the following criteria:
• the reset vector points to an address in the target flash area,
• the stack pointer vector points to an address in any of the target RAM area.
If all these conditions are not respected, the binary file is not programmed and the target
flash keeps its initial contents.
11.5 Bridge interface
The STLINK-V3SET implements a USB interface dedicated to bridging functions from USB
to SPI/I
2
C/CAN/UART/GPIOs of the ST microcontroller target. This interface is firstly used
by STM32CubeProgrammer to allow target programming through SPI/I
2
C/CAN bootloader.
A host software API is provided to extend the use cases.
