STM32F303VC : device not found - stm32

I am using STM32F303VC board, and using keil-5 tool for programming.I got demo program for STM32F303VC board provided by ST microelectronics.So, when I open this demo program (I have connected my board with system) I got this error:-
I don't know what is the reason for this, so please help me get out from this issue.

Got the answer, I have to install legacy support for my device.

Error in initializing ST-Link device. Reason: ST-Link DLL error

I'm trying to run one of the sample projects from Atollic's Getting Started Youtube tutorial. At the debugging stage, the captioned error shows up. I'm at a loss since my board is connected and the video doesn't mention anything about the hardware configurations.
Met the same error, though I'm using a different board (NUCLEO-L452RE). Solved this problem by clicking "ST-Link Update" in "Help" in STM32CubeIDE.

"No ST-LINK detected" error message, when trying to connect with ST-LINK Utility

I have a
NUCLEO-F401RE board
(with STM32F401RE)
and it has been working fine for the most part. Here recently, I followed a tutorial in the book
"Mastering STM32"
where it says to install
OpenOCD.
I had been following along before this as well, and I had been able to connect to my board and flashing it with no problem.
After attempting to get OpenOCD to work though, this is no longer possible. Every time I try to connect to my board, I simply get the following error message:
No ST-LINK detected
I have tried updating the drivers multiple times, rebooting the board, reinstalling the ST-LINK Utility, switching the USB-Cable, resetting the board and reinstalling everything and I have also tried the trick where you hold down the reset button and try to erase the chip.
So far, none of this has worked for me unfortunately.
Here you find a picture of my board.
On my desktop, I am using Windows 10. On my board, and I am using FreeRTOS.
Here you find an image of my Windows Device Manager.
I have also tried to update the firmware on my board using the ST-Link upgrade, but without luck. When attempting this, I either do not have the option to select my device (when using the .jar app) or when using the .exe app, I just get the following error messages:
No ST-Link device detected
Please connect it and then retry
I have not been able to find a solution for this anywhere, so I hope you guys can help! If you need any further relevant information, just let me know. Thank you very much.
As mentioned in other answers, the problem is almost certainly due to a competing driver (something like libusb) taking control of the device.
However, you do not need to "uninstall and reinstall everything" to select the correct driver, assuming that you have already installed it once before. Moreover, the reinstallation procedure most likely won't help, because the uninstallers usually do not uninstall the drivers anyway, and Windows will keep prefering the same wrong driver.
Instead, open Device Manager, find your STM32 STLink device, double-click to open the Properties dialog. Then click "Update Driver", then "Browse my computer for driver software", then "Let me pick from a list of available drivers on my computer", and you should see something like that:
You see that in this example, at least four different drivers available on the system are happy to service the device. The first two are generic libusb drivers, not specific to the dongle (OpenOCD is happy to use either of those, if I remember correctly). The ST-Link utility, however, wants a dedicated driver, developed by STM - those are the two entries below on my picture. If you do not see those, try installing the ST-Link utility again (no need to uninstall anything) or download just the driver from the STM website.
You can now click on the preferred driver in this list and have it replace whatever driver was assigned to the device before.
From my poor experience the "No ST-LINK detected" message in the STM32 Utility shows when you are disconnected or when other program is using a ST-LINK. So, if this start happens after installing OpenOCD try to uninstall this and try again (maybe with option "Connect under reset"?).
For your information. When you plug the cable to the PC and the board is power on then in the settings (STM32 Utility) you can see available ST-Links (even blocked). Here is example when ST-Link is blocked
From what I have learned and understood (but everyone can correct me :)), your board is divided in two parts :
The ST-Link debugger part ;
The rest with the actual microcontroller.
The ST-Link part is used to flash the microcontroller and can be used to flash any other STM32F4 device through SWD. With your picture :
The STM32 ST-Link Utility uses the ST-Link part of your board to flash it. My point is that if you have the "No ST-Link detected", the issue, I am quite sure, doesn't come from the microcontroller part but comes from the ST-Link part. And since you did say that it worked before you install openocd, I would suggest the driver part in W10 that may be the root of your problems.
Try to uninstall everything (and I mean everything) related to the STM32 (openocd, STM32 ST-Link Utility and its driver through Device Manager).
Reinstall only STM32 ST-Link utility (if you did uninstall the drivers correctly, it should ask you the permission to install the drivers during set up) and try to connect your board.
You can also try to remove the SWD jumpers (connector CN2) on your board to detach the ST-Link from the built-in microcontroller part. Since the ST-Link part is independent it will still be detected by the STM32 ST-Link Utility (but you will have to put the jumpers back if you want to actually program your microcontroller).
Just ran into this. The problem boiled down to using nucleo boards and trying to interface with them using older versions of ST-LINK (ST's search for ST-Link's first hit led me to stsw-link0004, which was not installing the right drivers). Why they don't point you to the latest greatest first, who knows.
Whenever I tried to install drivers, I could only select USB Composite device as a compatible driver, despite repeatedly uninstalling/reinstalling stlink0004.
You need to install the newest st-link e.g. stsw-link0009 (or newer).
Uninstall device (device manager had it under USB Composite Device)
Uninstall ST-LINK
Disconnect nucleo.
Reboot.
Install ST-link (stsw-link0009)
The prompt should have you install 3+ drivers. Not just 2.
Plug in. Voila.

how to deploy tizen tv application on emulator?

I'm a novice in tizen development.
When I run am app in the IDE emulator, the following message appears:
Launching AnalogicWatch has encountered a problem.
java.io.IOException: Both an author and a first distributor must be required.
Please check your profile information.
How can I fill those parameters to make the app appear in the emulator?
Thank you!
It seems that you need to install the certificate extension in the Tizen IDE. you can get details procedure in the following link:

Unity 5.3.1f1 crashing every time while opening in windows 10

freshly installed Unity 5.3.1f1
When tried to open unity it is crashing --
Tried with Run as administrator
Also followed instructions from
answers.unity3d.com
but nothing helped
I have added same question on answers.unity3d community -- But not got satisfying response. my question link -- You can check error log there
Can somebody help?
I am using hp pavilion p097tx laptop with windows 10 -- Did it make any difference? Any graphical dissimilarity? please advise.
Thanks
I have resolved my own problem
The issue was the malware software installed which was causing Unity crash.
I have unistalled Mekka as well as bonjour software. And restarted system then started unity with run as administrator with no issue.
So if unity crashesh and you doesn't know the exact cause, Then the issue might be the an malware dll or software which is present on your system. Check the error log which unity provides which will give you idea about the specific dll which is causing crash. Then check info about it on internet That might be an malware -- Remove that baster Restart system and open Unity.
-- Happy Gaming

Unable to start Stanford's CS106A Eclipse version - "Unable to access jarfile startup.jar" on Mac 10.6

I've been trying to do the Stanford CS106A course through iTunesU, but I keep running into problems with Eclipse. I tried getting Stanford's custom version with Karel, but that kept giving the "unable to access jarfile startup.jar" error. I even tried getting a current version and trying the instructions on http://www.freesoftwaremagazine.com/articles/getting_stanfords_karel_robot_run_debians_eclipse, but that threw null pointer exceptions when I tried to run a programming assignment.
I'm not sure what information to give, but I'm running Mac OS 10.6.8 (64-bit, I think?), and my Java version is 1.6.0_22.
Any help you can give me would be greatly appreciated. I've got algorithms in my head, and I need to get them out! :)
The correct download link for the Eclipse package recommended by the course is actually via the class page here: http://www.stanford.edu/class/cs106a/
The software link is in the sidebar, but it uses frames so it's difficult to link directly. Here's the software page without the navigation:

I had the same problem and had followed an older handout that pointed me to an older version of eclipse, I think pre OSX Tiger that will never work. Thanks for the tip pointing me to the right location, I downloaded it from http://www.stanford.edu/class/cs106a/ and it worked right away. Thanks becw
For those that are interested, this is even working in MAC OSX 10.10.1
