Unable to open USB STLink v2-1 on OS X

[pctj101]

I'm trying to program a Nucleo STM32L432KCU6.

I've verified the STLink v2.1 appears properly on OS X:
STM32 STLink:
Product ID: 0x374b
Vendor ID: 0x0483 (STMicroelectronics)

I've also updated my STlink v2.1 to the latest firmware:
http://www.st.com/en/embedded-software/stsw-link007.html
v2.28.18

And I see that the tcl config clearly addresses those Product and Vendor IDs.

Running openocd in debug level 3 mode:
openocd -s ~/zephyr/openocd-stm32/tcl/ -f stm32l4.cfg -c "stm_flash outdir/nucleo_l432kc/zephyr.bin " -d 3

We can clearly see that the proper TCL files have been loaded and vid/pid are being properly sought out.. however, we still end up with an error on open.

Debug: 267 6 hla_layout.c:40 hl_layout_open(): hl_layout_open
Debug: 268 6 stlink_usb.c:1642 stlink_usb_open(): stlink_usb_open
Debug: 269 6 stlink_usb.c:1659 stlink_usb_open(): transport: 1 **vid: 0x0483 pid: 0x374b serial:**

User : 273 49 command.c:687 command_run_line(): in procedure 'init' called at file "/Users/developer/openocd-stm32/tcl//stm32l4.cfg", line 2

Has there been any known issue where OS X is prohibiting any USB Port opens?

Hi

Sorry, I don't have any mac to try out. I confirm that you should be able to flash nucleo_l432kc though.
You might be able to get some help here:
