STM32CubeProgrammer on MacBook Air M2 won't recognize NUCLEO-WL55JC2

[Leif]

I'm trying my first Nucleo WL55JC2 dev board on my Macbook Air M2 (apple silicon). I am having an issue with connectivity. I have two of the same dev boards and multiple USB cables, and two USB ports on the Mac. All combinations give me the same result.

I am able to upgrade the firmware on the board using STM32CubeProgrammer, so that shows that communication with the board via USB is possible. However, in STM32CubeProgrammer, I am not able to connect to it via STLink (with either JTAG or SWD) . . when I try SWD, I get the following output:

09:07:10 : UR connection mode is defined with the HWrst reset mode
09:07:10 : ST-LINK SN : 005200303234510A33353533
09:07:10 : ST-LINK FW : V3J15M7
09:07:10 : Board : NUCLEO-WL55JC
09:07:10 : Voltage : 3.25V
09:07:10 : Unable to get core ID
09:07:10 : No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication

So it is reading information from the board...but can't go further.

Hello @Leif and welcome to the ST Community.

I suggest you to have a look at this FAQ. I think it may help you. Also, make sure you are using the STm32CubeProgrammer V2.19.0, USB data cables and not charging ones. You can also try different connection modes (under reset, hot plug, normal,..).

Best Regards.
