set the device to DFU mode through USB. It shows up in device manager. STM32CubeProgrammer shows the port USB1, and show serial number. I can select the address 0x8000000 size 0x40 and click read and see the result. But when I click on the Connect, it just hangs and fail. On the FW side, which function it calls to connect? I need t debug why it cannot connect.
