I am trying to setup a eclipse development environment to work with stm32f303 nucleo 32 board.
http://www.st.com/en/evaluation-tools/nucleo-f303k8.html
So far, the all the tools seems to be correctly installed and working: I have succefully compiled and started openocd debugger for stm32f4 discovery and when I connect stm32f303 nucleo 32 board and start openocd, the led on the board indicates that it is connected. (I have flashed the board.)
The thing is openocd get lost when I do step by step debugging and this seems related to the message openocd gives me when started (look for bold line):

Does someone know how to fix usb driver in that case, or it is possible that something else cause the problem?
In case you experience this issue on Linux, you have to configure udev rules to work with the device. Find the 99-openocd.rules included with the source distribution of openOCD under Contributions. Connect your ST-Link USB-device and run 'lsusb' from a terminal, it will list something like this:
Bus 004 Device 009: ID 0483:3748 STMicroelectronics ST-LINK/V2
Notice the value behind ID, you want to check the 99-openocd.rules to see if there is a matching entry supporting the device, in the above case it's this one:
# STLink v2
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", MODE="664", GROUP="plugdev"
Copy this file to your /etc/udev/rules.d configuration directory and reboot your machine. Then try debugging again.
The OpenOCD distribution includes some libusb drivers, and recommends to run the zadig.exe tool to activate them. This will solve your problem.

As #silverdr mentioned in the comments, disconnecting the device and reconnecting it worked for me.

trying to program and debug STM32F103 (Bluepill) from Atollic TrueStudio 9.3 I got following message:

Error in initializing ST-LINK device. Reason: ST-LINK: Could not
verify ST device! Abort connection.
Trying to do the same thing in St-Link utility works without any problems (also erasing and programming):
What could be the problem with this, why does it have problems with verification ?
Tnx for helping in advance!
The problem is that the ID of the STM32F103 on the BluePill and the ID, defined the debugger config files are different. Often the BluePills have counterfeit ICs on them in order to keep the price low, but these do not have the same ID as genuine ICs.
The Instructions/video below are made for STM32CubeIDE however they should also work for TrueSTUDIO.
Video about a workaround: https://youtu.be/bJYp8o7FoYo
Open the Debug Configuration Window
Select ST-LINK(OpenOCD) in the Debug Probe Dropdown
Search stm32f1x.cfg file the C:\ST\STM32CubeIDE_1.2.0\STM32CubeIDE and open it using notepad.
Search for this Line
Now change the ID from 0x1ba01477 to 0x2ba01477 as shown here
Save the file, now debugging should work
this solution also works for clone chips like CH32F103 which is in some cases on BluePill
the other solution is to change a parameter in "stm32f1x.cfg"
open it with a text editor and find this line:
swj_newdap $_CHIPNAME cpu -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id $_CPUTAPID
change "$_CPUTAPID" to zero at the end of line it should be like this:
swj_newdap $_CHIPNAME cpu -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id 0
after that :Open the Debug Configuration Window like picture above and choose "Select ST-LINK(OpenOCD)" in the Debug Probe Dropdown
then click "Show generator options…” and in Mode setup change"Reset Mode”For“Software system reset”.
both of ways works and i've tested them with CubeIDE and CH32f103c8t6.
remember to change jumper on board
jumpers : up = 0 ; down = 1
tl;dr: flashed firmware to 0x00000000 instead of 0x08000000, am I lost?
Hello,
my device is based on a STM32F103CBTx which came with a proprietary firmware and had readout protection on.
I connect to it with a ST-Link v2 SWDIO and SWCLK connected to PA13 and PA14 and this command:
sudo openocd -f /usr/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg
I don't remember how I removed flash protection, but it worked as the original firmware didn't work anymore. Then I created a simple hello world firmware which pulls up and down three gpios and flashed it. The gpios are pulled up and down in 700ms intervals.
After flashing, I can't connect with openocd anymore. I forgot to specify the offset, the manual says the offset defaults to 0 and as it worked, I suppose instead of the boot loader my shitty hello world is pulling up and down some random pins happily… Is this possible? All other threads I found say the boot loader is write protected.
This is the last contact I had:

Polling target stm32f1x.cpu failed, trying to reexamine

Any directions highly appreciated.
Edit:
What I get now, also tried another st-link:

No, it doesn't matter at all, they are the same.
After reset, the MCU loads the word at address 0 in SP, and the next one at address 4 in PC. The BOOT0 and BOOT1 pins control which memory gets mapped to 0x00000000. Usually, BOOT0 is tied low, and flash memory at 0x08000000 gets mirrored at 0x00000000.
instead of the boot loader my shitty hello world is pulling up and down some random pins happily… Is this possible? All other threads I found say the boot loader is write protected.
The factory bootloader is indeed write protected, openocd can't overwrite it.
However, your application could have reconfigured the SWD pins, by writing a wrong value in GPIOA->CRH or AFIO->MAPR, thereby preventing openocd from working. It's the most common cause of this problem.
Fortunately, there is a way to recover.
Connect under Reset
If the reset pin of the controller is held low for a while when openocd is started, the application is prevented from starting, and messing up the GPIO configuration.
Openocd can do this automatically, when
It's told to do so, the line reset_config srst_only srst_nogate is present somewhere in the configuration script.
The MCU reset pin is connected to the debugger hardware, pin 15 on an official ST-Link/V2.
Or you can do it manually, by whatever means your board provides. If you are lucky, it has a reset button, if not, you must find a way to somehow ground the MCU reset pin.
Pull the reset pin low
Start openocd
Wait until the Info : Target voltage line appears. Maybe a second longer.
Release the reset pin.
It requires a bit of trial and error, you'll get better with practice.
Then you can flash your improved application, which carefully avoids reconfiguring the SWD pins.
I am setting up openOCD and Eclipse on a new operating system, using a Nucleo F030R8 board that debugs fine on another system. When I run the debugger in Eclipse I get "error in final launch sequence":

and the LED LD1 blinks alternatively green and red. Similarly, I can run External Tools in Eclipse just fine, but this doesn't open the debugger. So it seems like I'm close, but something isn't quite right. Let me know if you need any other details of my system.
Using:
Eclipse Mars.2 (4.5.2)
Mac 10.12.1
OpenOCD 0.10.0-201601101000-dev
GNU Tools gcc-arm-none-eabi-5_4-2016q3
Ok so I figured it out with major credit due to http://www.carminenoviello.com. Running this in terminal:
>telnet localhost 3333
localhost: nodename nor servname provided, or not known
showed this wasn't working correctly. checking /etc/hosts, the file was empty. I changed it to:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
And that was that. Can now enter debug mode.
When I start a debugging session under eclipse (luna) for my STM32F429 Discovery board. I get the following error:

I did have this working for another ST-Micro board and I could do a full debug session with no problems. Suddenly it just stopped being able to access the board and I get the same errors for it as I get with this board.
I was hoping to be able to use the purely open source s/w that runs on Linux to be able to work with these boards. I'm hoping that someone can get me out of this situation.
Thanks in advance.
Cheers!!
What you use the command and debugger?
try:
openocd -f interface/jlink.cfg -f target/stm32f429discovery.cfg
I'm trying to use Eclipse with GNU ARM plugins to debug my stm32f4-discovery board, however, still no luck. The same board works perfectly in Keil running in the virtual machine, so, it doesn't seem to be hardware problem.
I use Linux Mint 13, I've installed all the prerequisites, I have created templated hello world project, it compiles, and when I try to start debug, it stops at the step "Configuring GDB", and after a couple of seconds it fails with the following:
Error in final launch sequence
Failed to execute MI command:

Then I tried to manually start openocd:

But, when started by Eclipse, it doesn't work, for some reason.
Well, then I tried to keep openocd started manually and alter my Debug configuration: at the "Debugger" tab, I've unchecked "Start OpenOCD locally". Now, debug session a kind of starts: debug perspective is opened, no meaningful errors are echoed, but debug buttons (resume, suspend, etc) remain inactive. The chip isn't even reprogrammed: previous firmware programmed from inside Keil keeps flashing LEDs.
