STM32CubeProgrammer reports no STM32 target found.

[JTomp.1]

I'm using the P-NUCLEO-STM32WB55 board and programming was working, but it stopped. I didn't change any jumpers, etc. I'm using a USB cable from PC to the ST-LINK connector. The last firmware successfully programmed was the BLE_TransparentMode example.

Log from CubeProgrammer:

10:19:39:114 : STLinkUSBDriver.dll loaded

Any suggestions greatly appreciated!

Thanks in advance.

I changed the reset mode from Software to Hardware and it works. Not sure why this works though.

I have same issue but hardware reset doesn't solve it for me.

Any idea what I might try?
