Some scripts to flash and debug stm32 boards

openocd for STM32

This repository proposes some scripts on top of openocd to flash and debug seamlessly official STM32 development board (Nucleo, Discovery and Eval series)

Prerequistites

• Functional gdb

Quick install and use

Install opencod

• $ ./bootstrap
• $ ./configure --enable-maintainer-mode --enable-stlink
• $ make

Load scripts

• Update setlocal.sh script with your local path to arm gdb, then source local script
• $ source setlocal.sh

Flash your board

• Plug your STM32 board to any available USB port
• For a STM32 L4 board (eg: nucleo_l476rg)
• $ stm32_flsh l4 binary.bin

Debug

• For a STM32 L4 board (eg: nucleo_l476rg)
• $ stm32_dbg l4 binary.elf

Commands

For ease of use, following command could be defined in a local .gdbinit

• define
• rst monitor reset halt
• end

openocd-stm32's Issues

Unable to open USB STLink v2-1 on OS X

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:** 
Error: 270 49 stlink_usb.c:1672 stlink_usb_open(): **open failed**
Debug: 271 49 hla_layout.c:47 hl_layout_open(): failed
Debug: 272 49 command.c:626 run_command(): Command failed with error code -4
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?
