I've got a new STM32L496G board I'm trying to program but running into an "st-link no target connected" issue. I've tried reinstalling the drivers multiple times but this hasn't resolved the issue. I'm running dual booted off a Mac and have to use a USB converter to connect the device, so I was wondering if using that converter could be causing the device to not be recognized. I'd appreciate any insight, I'm completely new to working with the board

I'm trying to flash my code to NUCLEO-L432KC(STM32L432KC) by TrueStudio. It was failed.
[
It looks tool cannot detect ST-Link probe. I just connected it by USB cable from PC (Windows10). Code and project file are generated by STM32CubeMX.
What is the missing? What should I do?
I have confirmed following.
From STM32CubeProgrammer GUI, it cannot detect ST-Link connection.
From STM32CubeProgrammer CLI, it can detect S/N of ST-Link. But cannot connect.
From STLinkUpgrade 3.3.0, it can detect device and S/N. Also can update to V2J33M25.
From IAR Embedded Workbench, it can build and flash code and debug. No problem at all.
It looks same result using by STM32F4 Discovery kit for STM32F429 MCU.
Make sure you don't have another program such as ST-LINK utility running while you use the debugger. Some versions of the ST-LINK "hogs" the debug pod access and other programs then would have trouble connecting to it.
Install the drivers https://www.st.com/en/development-tools/stsw-link009.html
Choose the correct micro in the debug configuration window
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.
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.
I'm trying to deploy my first Windows Phone 8 app to my brand new Lumia 920, after getting everything up and running on the emulator, but I'm running into the following error during deployment:
1>------ Deploy started: Project: AudioFilteringPhone, Configuration: Debug ARM ------
1>Deploying C:\Users\<username>\Documents\Visual Studio 2012\Projects\AudioFiltering\AudioFiltering\Bin\ARM\Debug\AudioFiltering_Debug_ARM.xap...

If I manually try to deploy using the Deployment tool, I get the same error. Does anyone know what the cause of this is and how to alleviate it? This happens even if I just start a new WP8 app and immediately try to deploy it, so it's something wrong with my environment, not my application configuration.
I had exactly the same problem, but solved it by simply rebooting the phone. No software updates were required.
It turns out that there were software updates that needed to be installed. If anyone knows a way to find out the names of the updates applied, I will post them here, otherwise all I can say is that I had to update to OS version 8.0.10211.204.
This also can be because of wrong USB cable or port. I have a long cable for charging which works with android devices, but doesn't with WP.
Or maybe using another USB port helped.
I installed on PC/XP USB driver for Acer Tab A100 from acer.com
plugin A100 to PC
Hardware A100 regognized as ACER MTP
THEH:
"Cannot install this Hardware
There was a problem installing This hardware Acer MTP
An error occurred during the installation of the device
The required section was not found in the INF"
Please, explain where i'm wrong..
Thanks, Victor
I had some of the same problems on Win 7 x64. The solution boiled down to I went to Acer support and downloaded the USB drivers for the A500 and installed those. I can now see the device storage, the MicroSD storage on the device and connect with adb (currently debugging through the Eclipse plugin). So it looks like those drivers do the trick, I think their installer for the A100 USB drivers is just plain junk right now.
One problem remains: I was getting a .Net error with Acer Sync when I plugged in the device, but I really don't care about that, so I just uninstalled that bad boy.
Wasted the whole afternoon yesterday on the phone and chatting with Acer, don't make that mistake, when it comes to connecting up a dev environment they are clueless.
It´s the only way to connect it, installing USB drivers for the A500 requires you to have installed windows media player 11.
