Hi

Did you get and install the latest version of STSW-LINK007 ?

Hi, Olivier

I had install the STSW-007 package. And upgrade firmware version to V2J33M25 with stlink, the type is STM32 Debug + VCP. When the upgrade finished, it also doesn't serial port in macos.

Hi Steve,

This version was fully validated with High Sierra.

Maybe something has changed around Virtual Port support in Mojave we are not aware of.

This has been escalate internally for verification.

I will keep you posted here.

Hi Steve,

Quick test have been made on macOS Mojave 10.14.2

- Connect a DK2 out of the box (ST-Link version V2J32M22)

- a new tty appear as /dev/tty.usbmodem14202 (tested with two DK2, same number)

- use "screen -L /dev/tty.usbmodem14202 115200 –L

- got the Linux prompt and able to interact with

So issue seems to come from your Laptop/MacOs setup.

Please keep us posted when you will fix it.

Thx and BR
