Hi, I have recently upodated STM32CubeIDE and have found that starting a new project doesn't generate a *.ioc file. I found a forum thread dated 7/2025 to a similar issue in versions 1.17-1.19 but the suggested work around menu options don't appear to be in v2.1.0. Any ideas? this is really annoying as I've got a 'journey to complet'e but I'm wasting my time getting the 'car to start'....

Hi!I am experiencing some confusing behaviour on an STM32H743 series chip:I am running an injected ADC channel on ADC2, with trigger from the HRTIM. The HRTIM is triggering at 8000 Hz (200 MHz clock, prescaler div-2 and period = 12500). The ADC generates an interrupt at injected end-of-conversion, with 64.5 cycles per sample in 16-bit mode. The ADC clock is running at 80 MHz, with prescaler div-4, i.e. 20 MHz.  When setting an oversampling ratio such that the conversion time becomes longer than the time between the trigger pulses, I always get half the expected frequency for the generated interrupts. For example, with oversampling ratio 64, I can calculate the conversion time as:t_conv = (64.5 + 8.5) * (1 / (20*1e6)) * 64 = 0.2336 mswhere the 8.5 extra cycles come from the fact that we are in 16-bit mode as per documentation. From this, the ratio between the conversion time and the time between two consecutive trigger pulses is about 2, i.e. for each conversion

Good day,After I did an upgrade to the latest version when I compile I get this error.Where can I get documentation on this.Never did an upgrade without issues.make -j48 all arm-none-eabi-gcc -mcpu=cortex-m4 -g3 -DDEBUG -c -x assembler-with-cpp -MMD -MP -MF"Startup/startup_stm32f411ceux.d" -MT"Startup/startup_stm32f411ceux.o" --specs=nano.specs -mfpu=fpv4-sp-d16 -mfloat-abi=hard -mthumb -o "Startup/startup_stm32f411ceux.o" "../Startup/startup_stm32f411ceux.s"../Startup/startup_stm32f411ceux.s: Assembler messages:../Startup/startup_stm32f411ceux.s:61: Error: bad instruction `rtc ldr sp,=_estack'make: *** [Startup/subdir.mk:19: Startup/startup_stm32f411ceux.o] Error 1

I have a STM32H732 processor connected to a ethernet switch with port based VLAN support.I use the processor to connect to two different interfaces which are separated in the switch.I wanted to be able to access the same two TCP ports in the processor from both interfaces.So I configured ETH_L3_FILTER_0 and ETH_L3_FILTER_1 with the two different IP-addresses used on the two interfacesAnd the ETH_L4_FILTER_0 and ETH_L4_FILTER_1 with the two different ports.But that did not work as I hoped.It looks like the L3_FILTER_0 and L4_FILTER_0 are used as one filter. and FILTER_1 as another.And maybe that is as intented but it is not super clear in the documentation.I may have to add that I have found and read...Is this correct or is there perhaps a way to use the L3 and L4 as separate filters so that I can get four different filters allowing two IPs and two Ports in any combination of ports and IP?Best regards 

Hi ST support team,     I'm using STVD version 4.3.12,  no matter create an empty project or open the existing project.  The MCU selection in Project Setting always empty.  But the same STVD installation package works in some other computers.     My computer is 64-bit x64-based processor, running Windows 11 Enterprise Version 24H2.     I tried re-register dao360.dll in administrator CMD, there was a period when it could be resolved, but I'm not sure if it was due to Windows updates or some other reason. Now it's not working anymore. CMD command:Regsvr32 /u "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO360.DLL"Regsvr32 "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO360.DLL" 

We are currently using the PM8805 in our PD (Powered Device) design.We have recently encountered field failures and suspect that the root cause lies in the customer's testing process.Our customer was using a Passive DC Injector (55V DC Supply) instead of a standard IEEE 802.3at/bt compliant PSE. During their inspection, they perform "Hot-plugging" of the 55V DC source directly into the RJ45 port.I’m assuming the PM8805 has to 'work through' the Active Bridge’s body diodes during the initial handshake (Detection/Class). Since the MOSFETs aren't active yet, all that signaling current must be passing through the parasitic diodes, correct?My concern is that when using a 55V direct injector, a massive amount of inrush current is forced through these body diodes before the voltage even reaches the UVLO threshold. Doesn't this put a lethal amount of stress on the bridge before the PM8805 can even start its control sequence?We performed a failure analysis on the damaged products and found the

Good morning!I've been working in a project whose purpose is communicate AEK-MCU-C1MLIT1 board and AEK-COM-ISOSPI1 through SPI/isoSPI protocols. At first, I've tried to apply the hardware configurations and script as mentioned in the user manual(UM3187) to exchange 512 bytes between two devices through isoSPI, however I don’t know how reliable the results in debug step are to assure this communication is working properly. Another detail that I've noticed is about disable pin, which stay always turned on, mainly when I select configuration as “micro” in  AEK-COM-ISOSPI1 Component RLA > Application Cofiguration. What should I do to enable AEK-COM-ISOSPI1 board?About the wire connections, I used as reference the board view within AutoDevKit Studio. I’d like to know if there is some connection that is missing, especially about the ISOm e ISOp signals, because the board view doesn’t show if I should to connect the USB port on the computer to debug step, for instance.

Hi,We wish to do a Boost PFC with L4986A and a  30uH inductor.Power is 2200W and Mains is 85-265VAC.When the mains is at 240VAC,  the inductor current would be discontinuous for some 80% of the mains half cycle.Is this OK?Will the L4986A be able to control it  to give a good power Factor with low THD?

I am designing a 3-phase AC to 24 V DC power supply and plan to use the VIPER26K high-voltage converter (as used in the STEVAL-VP26K02F evaluation board) as the main switch-mode controller in a flyback/isolated design. The target specifications are:Input: 3-phase AC, ~90–480 V ACOutput: 24 V DC, ~200 mAI have reviewed the STEVAL-VP26K02F datasheet and schematic. While I believe this device family is suitable for my application, I am unable to simulate the design in LTspice due to the following issues:The available OrCAD/PSPICE models from ST are not directly usable in LTspice.I cannot successfully import or convert the existing model due to signing/encryption and compatibility issues.The product page only lists PSPICE and SIMPLIS models, and I haven't found an LTspice-ready model for the VIPER26K.My questions are:Does ST offer a native LTspice (or compatible SPICE) model for the VIPER26K (e.g., VIPER267KDTR) that I can use for simulation?If a direct LTspice model is unavailable, is the

Hello,I am a graduate student working on power electronics research.I am using STDRIVEG600 in my experiments and simulations.I would like to ask if any simulation model is available for STDRIVEG600.If available, please advise how I can obtain it.Thank you for your support.Best regardslanrain

Hello everyone, I find your new product, the ST87M01-1301, an interesting alternative to Nordic or Simcom. However, I haven't found any hardware design guides for the module yet. Could you please provide some? A schematic would be really helpful, showing how to wire the pins and connect the SIM card, antennas, etc. What is the maximum current draw of the module? If you have any battery management products, how can they be used together (for example: BMS + STM-Host MCU + ST87M01 – an example schematic would be great) so that people can use your specifications as a guide and build their own prototypes with your modules. I really like how Simcom handles their documentation; you could certainly learn from their example. Currently, your documentation for the module is a bit chaotic and incomplete, as if it were done by an intern. Many greetings,Andreas 

Both the BoM and Schematic (in the Data Brief) do not show the part numbers or values for L2 and L4 on the STEVAL-STPM801 ORing circuit.  Which inductors are used on the reference design?   Thank you. 

Hello, I have a custom board with a STM32WB55CEU6 and I am trying to programm it through a Nucleo STLink with SWD. The onboard Nucleo CPU is detected and works fine if I add the jumpers, and I can program a different STM32 board with the jumpers removed as well, so the STLink is functional.It fails when trying to connect to the STM32 saying it's unable to detect the Device ID, so no SWD communication happens at all. I have connected SWCLK, SWIO, NRST and GND and checked the polarity multiple times. I also checked with a multimeter, and there is connectivity between the pins. I used a 10cm Dupont Jumper and the traces on the board are around 3cm long. Boot0 is tied to GND. Supply voltage is a clean 3V3 and I am using the internal SMPS, where VDDSMPS is at 0.97V if I plug it in. So I think the STM32 is powered and operational, just not able to connect. I don't really know what else could be going wrong on the board, so I came here to ask for help. 

When connecting to a charging port with a USB-C to USB-A cable, the device repeatedly switches between charging and not charging.If the STUSB4500 is supposed to support non-PD sources, how should I configure it to ensure stable charging in this scenario? Thanks!

Dear all, I have a custom PCB with the STM32WBA5MMG module. I missed the keepout requirement in the reference design and pads 2 - 5 and pads 56 / 59. These pads are connected to GND in my design. I did some signal tests, and I have a feeling the antenna is not performing well (I configured +10dbm). Can somebody confirm these pads connected to ground influence the antenna performance? Below is a snippet of the PCB design:   Thanks, Robin

Hello,I successfully used linuxptp with stm32mp257f-dk board, but now need to do the same with stm32mp157f-dk2. linuxptp was built from the same latest sources for both boards using corresponding SDK for each board.

Hello.   I'm having a problem with an STM32H503. I need to use the RTC, which is running on the internal 32kHz LSI clock. The clock configuration was created with CubeMX.   When I check the RTC, I see that it has only advanced by 21 seconds in 60 seconds. That's a deviation of 285%. The processor is running on the HSI clock, which is divided by 2, so 32MHz. Does anyone know why the RTC is running 3 times too slow?   Init of the RCC: RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI | RCC_OSCILLATORTYPE_LSI; RCC_OscInitStruct.HSIState = RCC_HSI_ON; RCC_OscInitStruct.HSIDiv = RCC_HSI_DIV2; RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT; RCC_OscInitStruct.LSIState = RCC_LSI_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE; // RCC_PLL_OFF; if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); } /** Initializes the CPU, AHB and APB buses clocks */ RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK | RCC_CLO

Hello ,I want to Access QSPI drivers in STM32H7A3VIH6. However in Cubemx there is only option of OCTOSPI1 and OCTASPI. My question is there way to use QSPI api directly like HAL_QSPI_Init instead of OSPi init?Or we have use OSPI only?Secondly i am using 2 external flash to be used in each QUAD SPI.

Same issue reported in 2020: https://community.st.com/t5/stm32-mcus-products/stm32g473-fdcan-pinout-contradicting/td-p/224770.As of DS12712 Rev 5, Table 13 Alternate Functions has PB10 and PB11 mis-labeled as FDCAN3_RX and FDCAN3_TX respectively.Under AF11, PB10 and PB11 are not available as FDCAN3_RX and FDCAN3_TX.

Our own non-secure application is based on "SMAK_Appli" in the STM32TRUSTEE-SM example and in principle, it works, but debugging is giving me issues. This is with STM32CubeIDE latest version and all tools software and firmware updated to their latest versions, too.Issue 1: Using STLINK-V3 to start debugging, whenever there has been a code change, the first attempt results in a verification error (see log below) and the second attempt then works. This is 100% consistent and terribly annoying since starting the non-secure debugging session is very slow to begin with.Issue 2: Using J-Link to start debugging, it claims flash was programmed (very fast) and debugging seems to work at first, but I found that flash programming was not effective. The flash content is always what it was programmed with using STLINK. So if I want to use J-Link, I have to program with STLINK (twice), then switch to J-Link but I cannot successfully program changed flash content with J-Link.Are these issues know and

I want to generate an SBOM (Software Bill of Materials) for my STM32 firmware project, specifically targeting the STM32H733 microcontroller. I have tried searching for guides or examples of how others have done this for similar projects, but I haven’t been able to find any detailed resources. Any guidance or references on generating an SBOM for my firmware project would be greatly appreciated.
