I have come across an issue which I believe is a bug in the implementation of the osThreadFlagsWait function. Scenario A thread is waiting on a flag (e.g. 0x2u) for a timeout above 0, before this timeout should occur, there are multiple other flags set on the thread (e.g. 0x1u) using osThreadFlagsSet, this results in the osThreadFlagsWait function returning with a value of osErrorTimeout sooner than the set timeout. Cause The xTaskNotifyWait function which is called by osThreadFlagsWait returns each time the 0x1u flag is set, resulting in this section of code being run: Note that t0 is set to the return value of xTaskGetTickCount() at the start of the wait loop, so is the start time, tout is a timeout value passed to xTaskNotifyWait, which is originally the set timeout, but is adjusted each time the xTaskNotifyWait function returns. The issue with the code above is that the value of td is the total time that the thread has been waiting, this is subtracting fro

I am trying to establish an ethernet comms with the STM32F207ZGT6 MCU.I have configured the pinout in CubeMX and followed various online resources for implementing LWIP, however I have had no success in discovering the device on my network, and thus am unable to ping. The Link led on the ethernet port lights up after my computer is connected, but no communication is acheived. I am using a DP83848MSQ/NOPB PHY. Could someone please shed some light on the CubeMX configurations for the LWIP. I have disabled DHCP and assigned a static IP. My computer is on the same subnet (192.168.1.xxx)as assigned in CubeMX for the MCU's LWIP settings. Further, both my computer's ethernet port driver and the MCU are assigned the same netmask (255.255.255.0). The MCU and PHY are configured to operate in RMII. I am currently not using FreeRTOS. I read elsewhere in a thread that there are some bugs associated with memory allocation for the heap, alongside issues with the HAL driver, ethernetif.c and lwip.c fi

Hello everyone,   as mentioned in the title, I'm using STM32WBA in a project. Immediately after sending data to the stm32wba  coordinator, I add an expression to the backup register and reset the processor using `Nvic_system_reset`. I check this at startup and then run a different routine. It runs continuously in a loop.   My question is, are there any disadvantages to resetting the processor? Would it cause problems like freezing? Does this situation lead to a logical fallacy? What exactly does the MCU do with the reset process?   HAL_NVIC_SystemReset();  

In the document UM3234 we see the following description of clock configurationOn my Nucleo board, I haven't blown any fuses and measured a clock frequency of 32 MHz. Since the XSPI is configured to have a prescaler of 2 by BOOTROM (also mentioned in UM3234), this implies that the board is using the default clock scenario. The document also mentions this regarding the nominal scenario."During secure boot, the boot ROM sets up PLL1 to switch to CM55, APB, AHB, and AXI clocking at the nominalboot frequency"Does this mean that if i dont have secure boot enabled yet, ill get the default clock, and as soon as I enable secure boot my clock frequency will increase to 400 MHz?. 

I've got a problem with MCU Selection not showing any options.Tried Reinstalling whole program also reinstalling Cosmic, I've got a working license for Cosmic also. Also with my professor we tried copying all files from his computer where it is working without problems (we are working both on windows 11). After that we used Revo Uninstaller to try and download both ST Developer Studio and Cosmic again but that didn't fix anything.We've run out of ideas why it isn't working. Even after connecting STM8S208RB and trying while it is connected didn't do anything.

Greetings! So I have a personal project, using a STM32U585 MCU, with a self-designed board, in which I have a bootloader and the main firmware. So basically I implemented a protocol for communicating with the board, I have a C program that sends a command and the board sends data (around 20Kb), using USB.The scenario is the following: I flash the firmware with the bootloader, after flashing, the bootloader jumps into the main program and starts running, I send a command (via host) to get data and the board sends me data and everything is running smoothly. The problem starts when I unplug the board and plug it again, when I send the command to get data, the board starts to send it and then it completely freezes. Another curiosity, this situation only happens when I plug the board in a USB hub... if I plug the board directly to the laptop, I won't have any problem. Any clue of what can be the problem? Power related? Is there any issue with the jump to the main pr

Unable to get stm32 project option in my stm32 CubeIDE software

Hello,I am working on using NRST pin in stm32g031j6m6 as GPIO, but it fails every time. I've changed many option bytes and even options present only on stm32g0x1 have workwd on my chip, except of NRST_MODE. If i want to change this option to 2 (gpio mode) and try to apply, the progress bar stays at 0% endlessly until i quit the STM32CubeProgrammer. I didn't have any problems with communication between nucleo and stm32g031. I tried to program my chip with st links built in nucleo u031 and f303, everytime without success. What else can i try? 

Dear ST Technical Support,I would like to inquire about the short-circuit protection behavior of the VN7003ALH high-side switch.Application: Board with 6× VN7003ALH outputs.Configuration: 24V supply from 200Ah lead-acid battery. Output wiring: 1.5m of 12 AWG.Issue: With output ON, a hard short circuit was applied via 600A mechanical contactor. The VN7003ALH did not survive — the package cracked (photo attached).Question: Is this behavior expected? We assumed the integrated short-circuit protection would handle such transients. Are there specific source impedance or di/dt limitations we should be aware of that are not covered in the datasheet? Best regards,Artem           

Hi All,I have been struggling with the CUBEMX (6.17.0). I just want to put here the facts. I am deeply disappointed about the support, but let's suppose it's minor and will be corrected no later than next week.I wanted check and understand the LCD settings with touchGFX since the newest version(4.26) of both did not worked together either. If I tick in the separate c and h files the cubemx generates the wrong files. Also the cubemx will not generate all of the files to build the setup. There are two files between the touchgfx and cubemx in the touchgfx library. Note: The older files from the s7 development board has the comments that it will be generated but just part of it. Note2: I bought the dev board for sure and identified these errors there. It's even bigger error in the STM32H7x7 LQFP176 since the XSPI1 and XSPI2 are available at HEXA_SPI, but it's the same behaviour as above. The right MCU cannot be selected. See the datasheet for the ordering number. It has to have H to g

On STM32Hxx and STM32N6 families I have faced a situation where I need to modify startup assembly code  (startup_stm32xxx.s) to copy code (.text) into ITCM or clear RAM/TCM areas, for clean data or to prevent ECC error (on STM32N6). But next time CubeMX generates code, those changes are overwritten. Same story with SystemInit function in system_stm32xxx.c. So either manual restoration or script must be done. But it's getting quite annoying after several projects. I believe the purpose of CubeMX is to ease development, so I make a feature request:Please add user code begin/end comment sections that exist in main.c also into startup_stm32xxx.s assembly and system_stm32xxx.c source files.For startup assembly I wish the user sections are:User symbols definitions.User data copy.User zero fill.For system file I wish the user sections are quite similar to main.c:User includes.User defines/constants/variables.In SystemInit() function:In the beginning.After VTOR settingAt the end.User func

I just started looking at the STM32C071 family as an alternative to the STM32F042 and STM32F072 we currently use. To my disappointment the USB stack for the C071 is a total mess (dozens of files and complete spaghetti) and on top of that it seems to be written by Microsoft. So there is absolutely no way we are going to use that.Did I miss some other option for the USB device library? This USBX stuff definitely is no option at all.At first glance it looks like there are no significant differences between the USB hardware of the C0 and F0 if only used as device not host. So I am wondering if I can simply use the F0 libraries (which we have debugged and optimized…) on the C0. Or are there any hidden traps?

Hi folks,Well, as the title says, I am having issues installing CubeMX on my M4 Macbook Pro (Apple silicon). I got the email for both the IDE and MX, and I was able to install the IDE just fine, but the link I got for MX seems broken. Is there any other way to download CubeMX? Any help is much appreciated.

Greetings,I have an ST32L151CCT6 part with pin PB5 connected to the DE pin on an THVD1400DR RS485 Transciever, my whole system is designed to be low power, and the MCU enters stop mode to achieve that from its side, every pin goes to analog mode. I have meassured the power consumption of my whole system when I take out the transciever and it reaches the expected 40uA.The problem:Current rises up to 11mA when I solder the transciever back, even so, I mannaged to find the exact connection with the problem, when I raise the DE Pin on the part breaking the direct connection to PB5 the higher current consumption problem dissapears.What kind of worked:Setting the PB5 pin to INPUT makes the current consumption go up to 150uA, wich is way higher than we aimed for.What I have tried so far:I tried placing a 470K resistor in series to the trasnciever and the voltage at the DE Pin went to 0.7 volts, wich shouldn't as the datasheet for the transciever states having an 2M pull down resistor. If I go

Split from FATFS for STM32u575 - this is a different issue.helloo, i did the same exact thing and everything compiled properly, but after running it, the code freezes when the f_mount() function is encountered. Did you find a solution to your problem ??  

Hi Folks, I'm working on pattern generation on GPIO pins and I've done it successfully using bare-metal programming approach. I used TIM1 to trigger DMA2 to take data from a buffer and send it GPIOA->BSRR.  But when I try to change the timer from TIM1 to TIM2 and change the respective DMA stream, the same code does not work. code:   uint32_t signal1[6]; //pattern no included // Enable clocks for GPIOA, TIM2, and DMA1 RCC->AHB1ENR |= RCC_AHB1ENR_GPIOAEN; RCC->APB1ENR |= RCC_APB1ENR_TIM2EN; RCC->AHB1ENR |= RCC_AHB1ENR_DMA1EN; // Configure GPIOA Pins 0-5 as output GPIOA->MODER &= ~0x00000FFF; // Clear mode for PA0-PA5 GPIOA->MODER |= 0x00000555; // Set PA0-PA5 as General Purpose Output // Configure TIM2 for DMA requests on update event TIM2->PSC = 0; // Set prescaler to 0 TIM2->ARR = 999; // Set auto-reload value (adjust for timing) TIM2->DIER |= TIM_DIER_UDE; // Enable update DMA request TIM2->CR1 |= TIM_CR1_CEN; // Enable TIM2 // Configure

Hello,Using a NUCLEO H7S3L8, I'm trying to run a test where, using circular DMA with a linked list, I'm trying to send a buffer in memory over to the SAI for audio playback, using an external DAC. This configuration is based on either other tutorials or the reference manual, but it always throws a User Error flag and calls the DMA's IRQ handler, right after the HAL_DMAEx_List_Start_IT() call (whether done on its own after the necessary configuration, or as part of HAL_SAI_Transmit_DMA()). Even with some changes, it always yields the same results. The only one that seemed to have any effect was setting the Transfer Event mode to trigger the TC flag for each linked list item, which confirmed that a transfer might have been completed, despite the error flag.I have also seen GPDMA being configured with circular, using both Standard Request Mode and a Linked List, but haven't gotten any success out of that myself (with even TC flag not being raised).In case it causes any comp

Hi all,I'm unable to install Cube IDE under W10.I tried to play with permissions/administrator/... I always get an error:NSIS error : Error launching installer.All other items (CubeMX, Programmer, Monitor ) were installed without any problem.Thanks for help.

I am working with the X-NUCLEO-NFC04A1 expansion board (based on the ST25DV04K) and I have some questions regarding the Energy Harvesting (EH) capabilities.My Setup:Hardware: X-NUCLEO-NFC04A1 connected to a host MCU. Observation: When measuring the V_EH pin directly, I see a very low continuous current (in the 0.3µA range), which seems insufficient to drive my target peripheral directly. My goal: I am trying to trigger an external circuit that requires approximately 7 mA for a period of a few ms. I understand that the ST25DV cannot supply this current continuously, but I have seen applications that use a reservoir capacitor to obtain high pulse charges that can be used to trigger the system.My questions:Is the low DC current at V_EH normal? Was the V_EH pin designed strictly to slowly charge a capacitor, rather than directly drive a load?Is it possible to increase the EH current? In addition to optimizing the antenna adjustment and coupling distance, is there any setting in t

Hello, I am designing a PCB atm with the STA8090WG and I am searching for a reference design/layout recommendation for this IC, including the caps to use and recommendations on the antenna matching. Does something like this exist? It would be really helpful for me.Thank you very much, Val

Hello,We are experiencing corruption of our external IS66WVO32M8 PSRAM while executing x-cube-ai generated code on target device STM32U585AIIxQ. This corruption happens consistently when running the model (i.e. running the ai_*_run() generated function), but cannot be replicated outside of it. Please see the issue description below. ContextWe are using the STMicroelectronics.X-CUBE-AI package version 10.2.0 (STM32CubeMX version 6.16) running the .a static library generated by the cubemx tool on our STM32U585AIIxQ target. This is a Keras neural network that has been successfully analyzed and "validated on desktop" using the tools provided through the cubemx X-CUBE-AI gui. The model requires 1.5MB of RAM, and for this we have an external PSRAM device (IS66WVO32M8DALL ISSI Octal PSRAM). Everything is apparently configured correctly, and we are able to initialize the model and run the inference using the interface provided at X-CUBE-AI/App/app_x-cube-ai.c/h in the generated code.

Hi guy I want to use Nucleo h755zi-q to sent modbus TCP/IP but I have a little time and I'm a beginner. I watched some GitHub but I don't understand. Some one can help me pls 

I am currently performing the bring-up of a custom PCBA using the STM32H755ZIT3.My design is intended to use the Internal LDO only, bypassing the SMPS to reduce component count (i.e. one less inductor in my layout).Here's few details about the MCU power section of my SCH (also, please check attached capture):SMPS Pins: As per the Reference Manual for "LDO-only" mode, I have grounded VFBBSMPS, VSSSMPS and VDDSMPS, whereas VLXSMPS is floating.VCORE/VCAP: I have placed the required 2.2uF decoupling capacitors on VCAP_1, VCAP_2, and VCAP_3. No external inductor is present on the layout.What I'm observing is that at power-on, VCORE remains at 0V. Consequently, the target is not detected by the ST-LINK. If I instead "jumpstart" the board by applying an external 1.2V to the VCAP nodes, the MCU becomes reachable via SWD, and I can successfully modify registers. I suspect a conflict between my hardware layout and the factory default reset value of the PWR_CR3

Dear ST Support Team,I am working on a reliability calculation for an industrial hardware design.
