I've a raspberry Pi with a actual Buster OS and a Rhasspy installation. Rhasspy requires a working audio environment, in my case a seeed Respeaker 2Mic-Pi HAT and a bluetooth speaker. Starting Rhasspy manually works without any problem, but all my attempts with a Buster light OS to start Rhasspy automatically didn't work. I tried to start Rhasspy with a cronjob #reboot, with rc.local and as a service but either the 2Mic-Pi HAT or the Bluetooth speaker didn't work. My final attempt was with a Buster Desktop installation. Same thing as with the light installation except when I start Rhasspy with a .desktop file that at least did the thing. So I want to know what makes the difference here compared with my unsuccessful attempts. Thanks in advance for a clarification... Jo
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 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 am using win-avr with eclipse to build and debug my project with ATxmega256a3bu devie.
when I tried to debug the code using avarice using following command:
avarice --part atxmega256a3bu -mkII --jtag usb --read-fuses
it shows the following error
AVaRICE version 2.9, Jan 7 2010 22:42:57
Defaulting JTAG bitrate to 250 kHz.
did not find any USB device "usb"
USB device not found
how to detect jtagice3 using avarice in windows?
If you don't have the libusb filter installed for that device avarice won't be able to find it.
You probably already have the Windows libusb port installed (if not, you can get it at http://libusb-win32.sourceforge.net); go to its bin/< platform > path and run install-filter.exe; then select your JTAGICE3 device.
Notice that once you have done this, your JTAGICE3 won't be visible to Atmel Studio anymore, unless you uninstall the libusb filter (using the same utility). If you need to go back and forth between avArICE and Atmel Studio, you'll have to repeat this cycle over and over (sorry...)
Another problem is that JTAGICE3 is not supported at least until avarice 2.13 (which is the latest at the time I'm writing this). I had to download the head sources and build them in cygwin to be able to use it. the flag you're using (-mkII) is for another model and won't work because their USB IDs are different.
I have set up the board according to the RX cpu example in eclipse, and everything seemed to be working fine till I wanted to get the example running on the board. When I click the option to hardware debug, I get an error saying "Error launching GDB server. Check installation".
Am I to re install eclipse, or the GCC toolchain for the RX cpu, or anything else?
I don't know anything about your specifics (that is Renesas or the RX62N). I do use eclipse for embedded work. Typically on a new platform I would make sure I can build and download a release version first. Once you have that working then see if you can get a Debug build and the debugger running. On the platforms I am used to, you have to put in hooks (typically just a single call) to enable the debugger. For exmple on the NetBurner the debugger can run over the serial port or Ethernet so the call has to specify which version you want to use. I know other platforms use JTAG debuggers etc, Typically a dev kit for the board comes with a manual that details how to get the debugger working. I doubt that you need to reinstall anything you just need to get the configuration set up correctly.
