I've been using a STM32H753I-EVAL2 board for several months now.
Last week I was suddenly not able to connect to the board anymore (tried with several tools: GDB, STM32cubeProgrammer, always same message like "STLink error"). I of course checked the driver was correctly installed and was the right one, reinstalled it, changed USB cable and ports. Also tried to connect to a Nucleo which was fine.
I randomly tried to change the power supply of the board from PSU (ie. powering through external power supply) to STLink (powering through USB) and it solved the issue. I was happy as I thought it was just a hardware issue like a conflict between both power supplies.
But today the board was not connecting anymore again. So I switched back the alim to PSU and it worked !
Did someone experience the same issue ? Or does it trigger something for someone ?

I have a Linux Manjaro KDE OS. I am very new to this system. My laptop screen is 10" in which makes it a bit difficult to do programming homework on. So, I tried to install DisplayLink and use a regular HDMI port as well to make a dual screen happen on 2
separate screens from my laptop. The regular HDMI screen attachment works fine to a point(settings will not save after restart despite choosing the options for this display only and making it the primary upon restarting I am constantly having to reset all of my settings). I have already tried to join the Manjaro public forums but never heard a response back for just joining meaning I did not make it past "Go". I am hoping that I am not overstepping boundaries here, but I believe there may be some coding involved in getting my DisplayLink connection to work (and possibly my settings to stick). I have already went to pamac and installed the required DisplayLink application there, but to no avail. Please help! I have some experience with Python, terminal, and other forms of coding.
I'm using an Arduino Leonardo. It worked very well the last time, but now my Computer (Win 10) doesn't recognize it anymore. (I used Win 10 before too).
After pressing the "reset-button" it works for a few seconds, but after that it's gone again.
Do you have any ideas, how I can solve this problem?
Reinstall the Leonardo driver.
change the usb wire.
if it is not worke then the boot loader got corrupted.

Sorry if this isn't the right place to ask, I'm new to arduino and I searched for my question here on ST and found similar but outdated queries that didn't help me so I might as well help others who might be having the same problem.
The very first time I connected arduino to my W7 laptop, it worked like a charm, installed new device drivers successfully, uploaded my sketch (which still continues to run every time its powered). I checked device manager and it showed the arduino under COM/LPT ports.
Then, after disconnecting the arduino and reconnecting, it no longer shows a COM/LPT section and instead shows an unknown device under USB. Every time I've tried uninstalling driver and reconnecting, it keeps giving me a driver installation failed error.
Googling for the issue told me to "update drivers" manually using the .inf provided with the Arduino installation through device manager, but when I tried that, it says the drivers aren't compatible with Windows x64.
Another tip from an arduino forum user told me to copy the arduino.inf into C:/Windows/inf, but that didn't solve the problem either
Any ideas?
I bought my Arduino Uno R3 a few months ago. It's been working like a charm since then, but today, it stopped interfacing with my computer. Let me be more specific. I have a 2013 Macbook Pro Retina with OS X 10.9 (Mavericks). It has the latest Arduino IDE installed.
I was using it today and after uploading a simple sketch (it worked for a little while) my Mac stopped recognizing it, and since, I haven't been able to access it. The LED connected to Pin 13 stays on 100% of the time. The RX/TX LEDs don't flash, but the main functions of my sketch (other than the serial functions).
Have I screwed my Arduino's Serial chip? What can I do? I am only 15, so another $30 is a little bit too much to spend to get another one.... :)
Thanks!!
UPDATE: I forgot to mention that I have tried my other Windows computer, and another cable, just to rule out those possibilities.
That is a very common issue with Arduino. I used to face that problem all the time while using Arduino. Though I never really found a solution for this, the problem did go away after sometime. Did you try resetting the uC using the reset button on the board, or restarting the IDE or your system if neither worked?
Make sure you have chosen the right COM port. On a windows system you can do this by going to device manager and look for the ports tab under it.
We have CI set up and very often our EVM boards (DSP boards) goes into a wrong state (reason unknown!!)and USB emulation was failing; to over come the issue we used to power reset the EVM board and everything used to work fine;
Now we have started using RPM (Remote Power Management) utility using which we can remotely reset the power on the device but unfortunately this doesnt seems to be working fine!!
We are able to reset the power on the EVM Board but we are unable to bring back the EVM board to working condition we are still getting USB emulation failure!!
Any thoughts on this; BTW we tried mulitple times resetting the power on EVM board using RPM but still same issue
Appreciate your help in this regard.
