ST-Link V3 not detected in Mac M2

[Louie88]

Hi,

I had to install STM32 tools on a MacBook Pro 2023 M2. I have a STM32H7474I-Disco board which works fine under Windows 11. When I connect the evaluation board to MacBook it pops-up a window to enable ST-Link driver. I enabled the driver but the usual new STL-Link USB drive with demo links does not appear in Finder... 

STM32CubeIDE (Programmer) reports no ST-Link is connected to MacBook. I am using the same USB cable as in Windows with an USB Type-A to Type-C adapter which works with all the external USB sticks, HDs.

I installed, STM32IDE, MX and Programmer and they seem to work right but the ST-Link V3 is not found.

When I connect the STM32H7474I-Disco board to MacBook Pro M2 then the LCD of the discovery board blinks 3-4 times (not enough power?) then stay on and runs my demo app just fine. Interesting...

Do you have any idea wha I did wrong?

Thanks,

Louis

Hello @Louie88 

I suggest you to take a look at this FAQ. It should be helpful.

Thanks, but it happens on MacBook Pro M2 (with latest MAC OS) not Windows. The Type-A to Type-C adapter is tested with many USB sticks/drives on that Mac including an 512GB Samsung M2 external SSD. I do not think this is a Type A to C adapter issue.

The article is not tooking about a adapter issue or a problem on only windows PCs. Please read the article carefully and try all proposed work arounds. I think they should be helpful.

The mitigation suggestions in the referred post:

1. Try to connect to another USB Type-C® port on your computer if available. Alternatively, using a USB Type-A port of your computer usually solves the issue. Done. MackBook Pro has 3 identical high speed USBC ports. None of them works with ST-Link V3.
2. Connect the STLINK-V3 via an external USB High-Speed hub to the USB Type-C® port of your host computer (tested hub reference: Anker332 5in1). I can't do this but the USB-A to C adapter works with every high speed memory sticks, hard drives, SSDs we have. All the peripherals work fine with this MacBook Pro using the same USB Type A to C adapter.
3. Use a different standalone probe to connect to your target board: ST-LINK/V2, STLINK-V3PWR, Segger J-Link. No chance, we do not have external ST-link adapters, like many others in this forum.

I do not know what else I could try. It is hard to believe that STM32H7474I-Disco board was not tested with a MacBook.
