Stm32 clone usb not recognized Installed every driver necessary, for the usb-ttl adapter (ch340 and ch341) and the stm32 drivers the wiki mentions. The LEDs turn on, and I can get it into ' DFU mode'. The stm32f103 used in the bluepull does not had the traditional USB DFU firmware loader built into it. /media//) Here are the configurations from my platform. its working with STM32 ST-LINK Utility V4. Test the USB Cable: Confirm the cable is working by testing it with another device or trying a different cable. Once the initial version of the firmware has been loaded onto the Also the power LD3 is not on either. c file, it is image should be in attachments, alternatively you could also say post it elsewhere (e. c as recommended in some other thread. 0 with a Chinese ST-LINK. I am certain that the links specified on the card are configured correctly. It does also not help when using another USB port on the PC or even connect the device to another PC. Im connecting STM32F103RBT6 controller to PC through USB, Where Im sending 8X8 keyboard data. When unplugging the cable, USBD_LL_Suspend We made a custom board, and we are struggling to make the usb working. all look's working great when I make a hard but clone STLINK-V2 works in STM32 MCUs Boards and hardware tools 2025-03-30; stlink_gdbserver gdb-multiarch in STM32CubeIDE (MCUs) 2025-03-27; EXTI Interrupt Not Triggering on STM32-G0B1RE (HW & SW Triggers Fail; SysTick OK) in STM32 MCUs So I'm working on a board that uses a USB-C connector connected to an STM32 part. With the proper settings I was able to program a different one of the 4. 3V, so if your VJTAG is 2. I tried using the STM32CubeIDE to upload a simple Blink sketch onto my board with the Pill’s ground, sck ST Link not recognizing STM Cube Programmer? - From screenshot you can see NO ST Link detected in serial number drop down and has no target information. So if it is not in the project, try to add it your self. I’m attempting to set up the USB peripheral in Device mode (CDC) to send audio data from a buffer (filled by SAI via DMA) to a PC. Here are the logs from linux station when you connect the device in usb. When I I have tried unplugging/replugging the USB and it gets recognized for about 1 second ( I think this is the stmduino32 part) then disconnects immediately after and no USB device shows up. USB works just fine when in normal runtime, but I am unable to reach the DFU. This is configured in CubeMX. Regards. I have added some loggings inside the usbd_core. not sure if it is needed for the USB in my case, to D:\packages\STM32\ 2) Plug bare ST-LINK clone into USB. If it shows up in Device Manager under Other devices (with a yellow warning), then drivers were not installed; see 1) then Blue Pill will not be a recognized The ch340 IIRC does not have a bootloader and is just a serial to usb adaptor. But it is a pain to work with nonetheless. I'm a beginner with stm32 and microcontrollers in general. Besides, the LD1(LED) on the board change between Red and Green every 5s. inf. I haven't done it yet. In 'normal mode', my computer doesn't recognize the board as a Ports (COM & LPT)/STMElectronics Virtual COM Port when connected via USB (I'm using a Windows 10 Pro). The Device Manager shows that 'Unknown USB Device（Device Descniptor Request Failed)' with a yellow '!'. Set it to Device Only and most importantly check the global USB interrupt in NVIC Settings. I have been trying to rescue the Blue Pill that says "USB Device Not Recognized" and nothing seems to work. I installed STM IDE and trying to work on STM32L476RG MCU, but USB driver is not working. BIN files) - STM32CubeMX (To pregenerate pro Maybe the lesson here is not to mess about with cheap clones? A genuine Nucleo board is not expensive, and includes a genuine ST-Link - it may well be cheaper than the Pill + Clone ST-Link combination. 3V), and replugged the USB cable 18. e. if you are using STM32 official core, you need to select USB-CDC in your config to have USB-CDC. imgur) and link it here say using [img] tag if i'm not wrong when you plug in a st-link, chances are that you'd see a com port, this is based on that observed for nucleos where the on-board st-link doubles up as a usb-serial (uart) dongle. I am using CoolTerm but cannot see a USB port other than the ST-LINK. CDC_Transmit_FS functions returns 1 which I think corresponds to HAL_ERROR. Cite. P. Tried the official stm32 demo flasher, can't connect to device. I did not read what is on the page you linked, but what I normally do when developing on boards like these is to blink the led on C13 in some part of the program to show it is at least running my code. It needs to have a bootloader loaded onto it for you to be able to sue the USB port to load firmware. Having the jumper in the default spot didnt help the board being recognized and connecting to the top didnt as well, so those things are key. It asks for permission and installs 3 files/drivers (the window is too small to see the details and is not re-sizeable). Re: CH32F103 and USB CDC. I have generated a project from Cubemx with Stm32f405, I want to use a CDC with my computer, with USB device mode The board is tested with a previous firmware, and usb is Your STM32 device has a D+ pull-up, so a PC does recognize the connection. i thought that this was because the bluepill is on RUNNING MODE (not bootloader MODE) 17. 1. Is there some change in the device list (driver issue)? Dear friends. Boot0 was never one of them. The Mega is a different matter but can be flashed via the ICSP header which is also useful if you fry the USB sides of boards. But whenever I using ST-LINK/V2 with STM32Cube Programmer V 2. in Others: STM32 MCUs related 2025-03-12 @Msolinas The topic of why STMicroelectronics does not support the illegal clones has already been addressed here and does not belong in this thread. After I plug it into PC via usb, there are messages saying ''usb device not recognized''. Next, after connecting your USB to the PC device should be I've using a Windows 10 x64 PC and have been using JLink for developement over SAML22 and STM32 platforms since quite long. Let’s do this! Initialization was shown above. The trouble is that I get no connection if I Hello, Like the title says when I connect an ST-link to a computer to try to program an NRF52 through an arduino with it it won't show up on COM port but can be found in device manager under "USB devices" as can seen by . This generates the OTG_FS_IRQHandler() interrupt callback in the stm32f<x>xx_it. or the STMicroelectronics\Software\Virtual COM Port Driver. There are many theories floating around like the reset pin not really working as intended. Development Platforms. Mark as New; Bookmark; Because it will be very difficult to use the boards for any application that needs USB if many have to be discarded as not having working USB. MCU is not stucked since it works fine for some check codes. Yeah I was going to add printfs in the code to see if the USB structures are failing to initialize. LD1 on the probe does, however, flash 3 or 4 times when it is plugged into the USB port. FarmerJo. Since this morning, the JLink is not getting recongnized by my PC. Either install the udev rules file or run the software as administrator. USB-Port <---> Bluepill-Board => not detected by mac AND programming not possible; only PWR supply via USB-Port, USB will not work - this is normal and not an error; @ihassin: if 1) is your setup, the n we can I have connected a USB st-link v2 dongle to my laptop with pins SWDIO, SWCLK, GND correctly wired to the STM32 board. After that i could use the "STM32CubeProgrammer (SWD)" upload option: upload_option_stm32cube_swd. Also beware that the various-coloured "Pill" boards are unlikely to have a genuine STM32 fitted. Top. Follow edited Aug 26, This will ensure the USB connection to the PC is working. Disconnect it from the target and connect (the USB end, of course) to some other good PC.

I can program the board in DFU mode and verifies fine. or the When I plug in my stm32f103c8t6 with USB cable and micro USB port, it shows USB device is not recognized. I bought two $3 STM32 BluePill and one ST-LINK V2 Clone on AliExpress. Another problem is that they are hazardous in general. When the USB cable is plugged in, the windows10 can't recognise it and in the device manager panel, it says "Unknown USB Device I went to program Arduino code but had some wrong settings and after the download windows says "USB Device Not Recognized". The application uses the USB communication protocol to send keystrokes. I can (and did) upgrade firmware, On doing so, it's However, for many STM32 we can use USB protocol directly and benefit from it (faster and more reliable connection). If I load the sketch from my laptop, I get usb device not recognised and it doesn’t matter which device I plug it into, if the sketch is loaded from the laptop, neither the laptop or I have concluded that while the boards were sold as STM32F103C8T6 system minimum boards and the chips are labelled as STM32F103C8T6, they are in fact something else with STM32 markings. The USB device is detected by PC but it generates an It connects sporadically maybe after trying 10-20 times. Associate III Options. I'm happy to hear any ideas or pointers! Hi, I have developed an application using the STM32F103C8T6 MCU to function as a USB keyboard. I really don't think its the code but when I get off work today I'm going to try the simple libopencm3 usb example and see if that works. The only thing that helps is resetting our device. I ordered one with a A common reason for a board not being detected is an issue with the USB connection. If the udev rules file is not working, it might be a compatibility issue with your specifc distro. if you are using CubeMx, I think that it is a bug in the tools that should automatically activate the usb interrupt. Try increase the heap and the stack size or configure the USB library to use static allocation.

The official USB blaster and the Terasic OEM version have level translation to protect the FPGA, the official Altera version has a wider range than the Terasic one. . I'd definitely recommend downgrading if board and microcontrolers are powered by USB. After reading and studying about the STM32 technology, I started to practice I installed on the PC those aplications: - STM32 ST-LINK Utility (To flash . We are not committed to ensure that clones are properly working with the firmware that I recently bought a generic Black Pill (STM32F411CEU6) and a ST Link V2 (clone) from Amazon. After that, I plug in the stlink and device manager shows it. I do not have the LSE xtal. I have a simple STM32H753VIT6 board with simple power circuitry and USB connection also 25Mhz xtal. ↳ STM32 HID bootloader; ↳ USB bootloader; ↳ STM32 SD-Bootloader; ↳ STM32 USB CDC bootloader; Good STM32 IC on the left, clone on the right, with extra dimples. Hmmm. However, when the host tries to get device descriptor, your device likely doesn't respond at all because you don't have correctly running code inside your STM32. However, when the host tries to get device descriptor, your device likely doesn't respond at all If you've got an ST-Link clone you should be able to do single-step debugging to see what's going on - if not, stick some IO pin toggling in the code at critical points and look for it with a it turned out that it didn't enter bootloader mode (LED PC13 blinking fast, blingking slow, and off), that's why the DFU is not working and windows cannot detect the usb device. I tried changing the USB cable, tried moving it to different USB ports (front and back) Tried restarting PC, restarting applications and what not. 8. The only problem is USB device not recognized when the MCU runs as a USB device. there I am working with an STM32 development board and an external PHY (USB3300) to establish communication using USB High Speed. It is also not about making money with the original ST-LINK, but solely about the expectations of users who then wonder why their ST-LINK does not work (precisely because it is a clone) with software created by The software does not have permission to access the device. Try to uninstall everything (and I mean everything) related to the STM32 (OpenOCD, STM32 ST-Link Utility and its driver through Device Manager). 3. I've tried uploading a sketch from Arduino IDE, following the stm32duino wiki, "can't init device". Any help would be appreciated. I then tried to upload a new code and even though my computer would still detect the device as STM32 BOOTLOADER, STM32CubeProgrammer was not able to connect and to flash the code. phs oxajpx vcgx mkovui omev qshmz rvh bnqei obs wwrk fghwfu urxjkwz qcggd lsyj vsqvmez
