Hi everyone,
I recently flashed new firmware onto my STM32F4 board using STM32CubeProgrammer, and now the tool won’t detect the device over USB anymore.
It was working fine before the flash, and nothing in the hardware setup has changed. The device still powers on, and I can see the USB connection briefly appear in Device Manager, but STM32CubeProgrammer shows “No ST-Link detected” or just hangs on connection.
I’ve tried different cables and ports, and even reinstalled the drivers, but no luck so far. Is it possible that the firmware flash disabled USB or changed the boot mode somehow?
Also, if anyone has recommendations for tools that start with S (like ST-Link Utility or Serial monitors) that might help troubleshoot STM32 connections, I’d appreciate it.
Thanks!
