Open source ARM Debugger
By Roberto61
#189449
I'm trying to use the System Workbench for STM32 with the nucleo-l476rg.
I'm using Ubuntu 14.04 .
I have no problem importing and compiling cubeSTM settings projects, but attempting to debug from eclipse, openocd hangs (waiting the server to respond I suppose) with the message:

Error message from debugger back end:
localhost:3333: Connection timed out.


Launcing openocd from terminal and adding the log-file and debug options (-l mylog -d) I got in the last lines:

The error seems generated by the function usb_open(dev), but I'm not sure of this.
- the usb device is regularly enumenrated (lsusb -> Bus 002 Device 004: ID 0483:3748 STMicroelectronics ST-LINK/V2)
- the permissions are normally write in the file /etc/udev/rules.d/49-stlinkv2.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", \
MODE:="0666", \
SYMLINK+="stlinkv2_%n"

- the libusb-dev is installed (of course)

also, using a c simple test code which uses the function usb_open(), I got the following result:
bus/device idVendor/idProduct
002/004 0483/3748
- Manufacturer : STMicroelectronics
- Product : STM32 STLink
- Serial Number: 0672FF515456707067072452

and many other info regarding the USB device.

Pease, can someone confirm the compatibility of openocd with nucleo-l476rg in linux?
Thx
