STM32F746G-DISCO: ST-Link Port Broken, No Exposed SWD Pins, No Boot0 Pin

abdelwahedbaha · ‎2025-03-24

I’m working with an STM32F746G-DISCO board, and I’ve encountered an issue with the board. The ST-Link port is broken, and unfortunately, it cannot be soldered. To make matters worse, the SWD (Serial Wire Debug) pins are not exposed on the board, and there are no Boot0 pins either.

Unfortunately for you I don't see any other solution than trying with an external ST-LINK by soldering wires on the solder bridges SB14 to SB17.

The solder bridges contains resistance on the board ( in the schematics it's mentioned as only solder bridge), what about them , could i solder over them ?

I think they are 0 ohm resistors (I don't have the board). You need to check from your side. If yes solder over them.
