STM32 MCUs Boards and hardware tools

Dear all,I'm unable to connect via SWD to my STM32F103C8T6. What ever I try I get no target found with STM32CubeProgrammer or ST-LINK Utility (I have tried all combinations at slow and high speeds). - device is virgin- BOOT0 is low- NRST unconnected (shows 3V3) and connected/removed while testing- Connections go through from ST-Link to STM32 pins- 30 Ohm and 0 Ohm tested for SWCLK and SWDIO (GND and 3V3 connection to ST-Link with no resistor)- Correct mapping of ST-LINK pins to STM32 checked multiple times- There are no obvious shorts between any of the paths- 3V3 is stable and GND closed- The ST-Link was tested with a "blue pill" board with the same STM32 on it and it worked flawlessly I have also tried:- Cutting the path to the esternal 16MHz crystal curcuit- Connecting/Disconnecting VCC- Soldered a new STM32 onto the board I am currently run

  Hello everyone, I’m facing an issue while trying to debug my project custom_for_stm32f103c8t6 in STM32CubeIDE. When I launch the debug session, I get the following error message: Error in final launch sequence:Failed to start GDB server What I’ve tried so far: Installed ST-LINK driver (STSW-LINK009). Changed USB cable and port. Reset the STM32F103C8T6 board. Interestingly, I can still flash the firmware successfully using STM32CubeProgrammer, but debugging through STM32CubeIDE fails with the error above. Unfortunately, the error still persists. Has anyone encountered this problem before and found a solution? Any guidance would be greatly appreciated. Thank you in advance!    

Hi, I tried to configure the USB Host for a project, but it’s difficult to configure, and I am not finding any online support available for the STM32H5 series controller.My requirement: I configured PB4 as an output, which is connected to a green LED. Whenever I plug the USB into my controller, the green light turns on, and whenever I remove the USB from the controller, the green light turns off.I’ve tried some methods, but they are not working. Can anyone please help me?

I have a NUCLEO-F103RB (MB1136 rev C05). My goal is to remove the ST-LINK and power via a hat supplying 3.3v. For the 3.3v I have: Moved JP5 to pins 2-3. Checked JP1 is removed. Removed SB2 zero ohm resistor. Removed SB12 zero ohm resistor. Verified my shield is putting out a good 3.3v which is attached to connector CN7 pin 16. For the HSE I have: Removed SB54 and SB55. Soldered zero ohm resistors to R35 and R37. Soldered 20pf capacitors to C33 and C34. Removed SB16. Removed SB50. Added 8Mhz 16pf crystal X3. The ST-LINK is still physically attached at the moment, but I do plan to cut it off once things are working. The board comes up and accepts programming and works in the debugger. Stepping through the initialization it gets to where the HSE is set up and then sits in an infinite loop waiting for the HSE to come ready. I tried replaci

Hello, I’m having a problem with a board I’m developing based on the STM32H747BIT6. The issue is related to SPI communication. When I connect any device to the SPI bus, the signal level drops from 3.3 V to around 1.5 V. I have tested different SPI peripherals, but they all show the same behavior. Could this be related to the drive strength or power capability of a specific pin?

Hi all, I have a small issue with the STM32N6570-DK board and the VENC_SDCard example code. The PN12 pin has a voltage of 0V (card inserted) or 1.80V (no card inserted); on the MCU side, the GPION data register (IDR) always shows a logic 0 in both situations. The VENC_SDCard / VENC_SDCard_ThreadX example code basically jumps over SD Card detection as it assumes a logic level of 0 == card present. If there is no card, mounting fails and aborts further processing. I have the requirement to react to card inserts / removals, so I'd like to trigger an interrupt or at least be able to read a logic high once in a while but could not find out what exactly is missing in the code. * I tested with an empty CubeMX project and set this PN12 to input; here I do see logic level changes.   * I susptected the VDDIO voltage domains to be at 3V3 for that block and manually switched VDDIO_SD to be at 1V8, but that did not show a change as well

Hello ST Community,My name is Gorakhnath. I am currently pursuing M.Tech (Power Electronics and Drives) at NIT Kurukshetra. I am using the STM32F4DISCOVERY (STM32F407VGT) board and I need stable DAC outputs for my hardware application.What I need (requirement)When the DAC command is 0 V, I need the output to be as close as possible to true 0.0000 V, because my external circuit maps:0 V → 0 A3 V → 50 AEven a small voltage like 0.045–0.05 V produces unwanted current (~0.5 A) in my system.Issue / ObservationOn both DAC pins:PA4 (DAC_OUT1)PA5 (DAC_OUT2)I measure about:~0.05 V (sometimes ~0.045 V) when

Hello,I got a radio MCU which connects to cloud and can receive binaries from database. And I got a STM32 that controls some stuff, including other MCUs. In production this means a lot of headers and programming time for all of them, no way to update remotely, and even if the code is thoroughly tested - glitches are still possible.So I want to connect things in a chain, so that if something apart from the radio crashes - radio MCU could re-flash the whole system. This of course could be done with UART when using bootloaders, but this again means you have to pre-program bootloaders on MCUs, and there's still a very slim chance it might fail.So I need an example of how one MCU can flash another via JTAG or SWD (preferably), and then verify the result. From there I could get it to work on Arduino / STM / AVR / radio ARM. What I really want is a proof of concept simple test example to show it works with the peripheral (bit banging is always possible, but surely ther

Hi, I’m using a NUCLEO-144 (STM32H563ZIT6) development board with only the board USB STLINK-V3EC port connected. TRACE and DEBUG are enabled with Serial Wire in the configuration file, and printf is routed through ITM: int _write(int file, char *ptr, int len) { for (int i = 0; i < len; i++) { ITM_SendChar((*ptr++)); } return len; } SWV is enabled in the debug configuration, the core clock is 250 MHz, and the SWV window (port 0) shows output correctly in STM32CubeIDE.  

When will the NUCLEO-C5A3ZG  be available via distributors?The st.com site lists it as available(mass production), but none of the distributors has listed it at all. And the estore lists it as coming soon. Do you have any more concrete dates, will it be available anytime soon?   Best

Hi    For some of my project, I need to measure the power consumption of the STM32N6570-DK while running a model on the CPU only versus an NPU + CPU accelerated workload.   I am following the guide  1. How to measure power on the STM32N6 - STMicroelectronics Community

Hello All,I have the NUCLEO-C562RE board and I wanted to get started with it. But I am lost and not able to find any documentation related to architecture manual or user manual. I am new to ST boards, previously I used Aurix TC375. Has someone here in the community used this board or similar one and know how to work around it? It would be really helpful.Thanks

I have the following original debuggers:Stlink V2Stlink V3_SETStlink V3_MINIE (2 pieces)I was recently testing a simple board with an STM32U083 (powered by 3.3V) and found that two Stlink V3 MINIE units could connect to the MCU. Meanwhile, both the V2 and V3_SET work without any issues.I observed that after connecting (SWDIO,SWCLK,VDD,GND) to the powered MCU, both the V2 and V3_SET leave SWDIO at 3.3V (pull-up in the MCU) and SWCLK at 0V (pull-down in the MCU). Whereas the MINIE maintains a 3.3V level on both SWDIO and SWCLK. Out of curiosity, I connected an external 10k pull-down resistor to both SWDIO and SWCLK and observed that SWDIO drops (which is fine), but SWCLK does not, meaning that the Stlink V3 MINIE actively holds SWCLK at 3.3V. Am I doing something wrong, or are both MINIE boards defective?Best regards,Michal Dudka

How many uart channels are available on STM32H573I-DK Discovery kit.I am Looking for atleast two channels..Thanks in advance...

Hello, I am using an STM32F407VGT6 board with the ST-LINK debugger.When I plug the USB cable into the board, the LD1 LED on the ST-LINK stays Green and does not turn Red. From what I understand: Green LED indicates that ST-LINK is powered and idle. Red LED should appear during debugging or when an error occurs. However, in my case the LED always remains Green. My questions: Why does LD1 remain Green when I connect the board? Under what conditions does LD1 turn Red? Does a constant Green LED indicate that the MCU is stuck (for example in HardFault or reset)? I am using STM32CubeIDE for programming and debugging. Any guidance would be appreciated. Thank you.

Working with a NUCLEO-L552ZE-Q  development board.   Requirement is to interface this board to another larger board where all the pinouts on unpopulated footprints for CN11 and CN12 ( the "Morpho" connectors ) can be brought out.   Therefore, the posts that stick out the bottom of the board must all match up in height.  The Nucleo PCB design files have listed the populated connectors CN7,CN8,CN9,CN10 on this board as CON_SAMTEC_SSW-110-23-X-D_N144_ARD      ( pin counts varying of course )With an accurate digital caliper, I measured the posts that stick out of the bottom of this board measure 9.1mm long, taking the thickness of the PCB into consideration.I bought this part ( SSW-110-23-G-D )  from Samtec and saw the post length and post geometry is NOT the same as what is on the board already populated.  I measured the posts on this part number.   The posts on this specified part number are

hi guys ,  I have been working on a stm32 project like a digital automotive cluster using STM32H7A3ViT6 MCU . I am using the LTDC module to drive the display . now the problem is the mcu dosent run the code on powerup but it ll do when i press the reset button . i have been debugging it for a long time but couldnt find why this happening to this .  now since it is automotive the input voltage is at 12v so itll be converted to 5V 5A using a buck converter and then to 3.3 using a LDO , thats how i power my MCU . now the reset circuit          and today i removed the capacitor from

Hello,I would like to build up an USB-CDC communication which gets the commands from the PC and forwards the messages to CAN. I have choosen a Nucleo-G431RB-C04 board, which have a FDCAN and a USB-FullSpeed inteface also. Do I able to create an USB-CDC for the mentioned board? I have read several different information of the USB interfaces on the Nucleo boards, and I would like to be sure before I will buy the mentioned card.If not, please recommend for me concrete Nucleo board type for this task.Thanks.

Hi everyone,My company recently purchased a new ST-Link/v2 programmer. The problem is that after the firmware update, the device stopped working, and when I press the Connect button on the STM32CubeProgrammer, the following error appears:Error: ST-LINK error (DEV_USB_COMM_ERR)I tried using an ST-Link/V2 programmer I bought a few months ago, and everything works fine (I only replaced the programmer, same USB cable, same programming cable).The programmer is original, I'm sure of it. I purchased the programmer from DigiKey.

Hi,I powered the NUCLEO-F410RB board externally by changing the JP5 jumper to select the E5V power supply and applied 5 V to the E5V pin. Initially, I did not have an external ST-LINK, so I switched JP5 to U5V and programmed the Nucleo board through USB.During this back-and-forth process, I powered both internally and externally at a time. After this, the board started consuming more current, and U1 in the NUCLEO-F410RB schematic overheated. Eventually, the VOUT and GND pins were found to be shorted.

Is there any alternative of "B-CAMS-OMV" to use with "STM32F746G-DISCOVERY" as in my region it is not available and the cost will be huge if I want to ship it to Bangladesh. So, is there any alternative modules that I can search for?

I can't get the STLink drivers installed on Windows 10 / 11 aarch64 Parallels VM running on Mac M1.Is there any support for ARM64 Windows STLink drivers?

Dear ST team , My STM32H753ZIT6 MCU is designed for working at 3.3V, Is this voltage compatible with the ST Link programmer? I want to know whether I need to put any level translator in between for SWDIO, SWCLK, SWO, VCP_RX, VCP_TX, NRST signals and the programming connector if 3.3V is not compatible.RegardsShyam

 Can somebody tell me whether I am, or not, powering this STM32H725RG in the right way?As far as I know, after reading several times the specs, the 68 pin package doesn't have LDO (SMPS only).I've built my first board this way and the MCU got burnt. Thanks.
