Hello, I work on a STM32F042G6Ux mounted on a custom board, and I want to automatize the flash by using command line and STLink (I'm using V2-1 one). STM_CLI works well to unlock the reading, unfortunately I read that ST won't deploy it on ARM architecture, and I want to work on Raspberry Pi. That's why I decided to use OpenOCD (v0.12.0) to flash my STM32. However, there's a problem using it : I have to switch power supply to apply the changes on the option bytes. I want my command line fully automated, and this is problematic. config.cfg : adapter driver hla hla layout stlink hla stlink_backend usb hla_vid_pid 0x0483 0x3744 0x0483 0x3748 0x0483 0x374b 0x0483 0x374d 0x0483 0x374e 0x0483 0x374f 0x0483 0x3752 0x0483 0x3753 0x0483 0x3754 0x0483 0x3755 0x0483 0x3757 transport select hla_swd source [find target/stm32f0x.cfg] reset_config srst_only srst_nogate openocd command :

Hello,I am currently using the STM32H7S78-DK development board. I would like to run TouchGFX together with ThreadX (Azure RTOS).Specifically, I would like to know:How to configure the project in STM32CubeMX to enable both TouchGFX and ThreadX.How to properly set up the system tick / timebase so that ThreadX and TouchGFX can work together without conflicts.Whether there is a simple example or reference project available for STM32H7S78-DK showing TouchGFX running under ThreadX.A step-by-step tutorial or minimal example project would be very helpful.Thank you in advance!

Hi,I found a bug on new version 2.18 STM32Cube programmer.Of course, I have the same problem with the new version of STM32CubeIde 1.17It looks file STM32_Prog_DB_0x483.xml in \Data_Base folder has changed between versions 2.17 and 2.18If I use the file STM32_Prog_DB_0x483.xml from the version 2.17 and I replace this file in version 2.18, I can access my STM32H730 device.We tried it on 2 different computers.I do not really understand the xml file differences, so I do not know if I can continue to use STM32_Prog_DB_0x483.xml file of version 2.17 with version 2.18 and STM32CubeIDE 1.17Do you have a workaround ?Sébastien

Hello everyone,I am using Nucleo H745ZI dual core and I want to communicate intercore by OpenAMP.The ST only giving example send message from core M7 to M4. But I want to send message from core M4 to M7, I tried follow the OpenAMP flowchart but not working.Do anyone has the example of OpenAMP send message from M4 to M7?

Hi,My battery (++ LTO/Bucks) that runs everything on my PCBA is connected to VBAT (pin 1). Before the connection I have a voltage divider factor of roughly 1.374, but what I read on the pin via ADC1 channel 18 (what VBAT is routed to internally) seems to be non-sensical. With a battery voltage of 3.6V I measure roughly ~1160 mV (after multiplying by 4 and 1.374). When I tried replacing the resistors in my voltage divider by smaller ones I got higher measurement values.VBATEN is enabled in ADC12_COMMON_CCR. Also tried to enable MONEN in PWR_BDCR1, but that didn't make any difference.What's could be the issue here?

I'm trying to drive the PWM of an STM32G0 but the waveform generated had an inconsistent period between bit 0 and bit 1, and I can't understand why I'm using TIMER 4 on Channel 2. On the main.c I'm initializing MX_DMA_Init void MX_DMA_Init(void) { /* DMA controller clock enable */ __HAL_RCC_DMA1_CLK_ENABLE(); /* DMA1_Channel2_3_IRQn interrupt configuration */ HAL_NVIC_SetPriority(DMA1_Channel2_3_IRQn, 0, 0); HAL_NVIC_EnableIRQ(DMA1_Channel2_3_IRQn); } and TIM4 configured as  void MX_TIM4_Init(void) {

Hello Forum,I am trying to install STM32CubeMX version 6.15.0 on Windows 11 (64bit).  I want to install it for "all users".  I've downloaded and extracted the archive.  I can run the installer 'SetupSTM32CubeMX-6.15.0-Win.exe' with Admin privileges and it extracts and runs to the "Select Install Mode".  At this point if I choose "Install for all users" then the dialog just exits and nothing happens.  It works as expected with STM32CubeMX version 6.12.0Does anyone have any ideas on what's going wrong? A big ask I know.  Can anyone suggest where to look for clues, are there any install logs that may give me a clue as to what's happening?Here are the machine details:Windows Type: Windows 11 Enterprise, Version 24H2, OSBuild 26100.4946Processor: 13th Gen Intel(R) Core(TM) i5-1335U (1.30 GHz)RAM: 

Hello, I start using Free RTOS on H755ZI dual core, I only use RTOS on core M7, core M4 do nothing and I received a notice from CubeMX:"CubeMX strongly suggests to use a time-base source other than SysTick when FreeRTOS is used."But I can not change Systick to other timer be like the image above. What setting step did I miss?

Hi,I'm getting build error after configuring the ethernet with LWIP. not sure what is the issue.Attaching the screenshot for the reference.attaching the code for reference. please help me to debug. as I'm facing this for ethernet configuration. what additional changes needs to be done in the flash or somehwhere as its memory related issue.Thanks,Harshitha

The errata for the STM32U575 series includes the following: We would like to use the first option of the 2 listed workarounds (the one that does NOT require disabling and reenabling the ICACHE).  Does ST have any implementation examples of this workaround? I am confused about why it is necessary to put the low-power entry code in a non-cacheable region.  We use a WFI instruction to put the MCU into STOP mode.  If we could ensure that the WFI was in the last 2 bytes of a 16-byte block of memory, would that fix the errata?  This way, the next instruction after WFI (and thus

I have the STM32N6570-DK board, and I was able to execute the example from:- https://github.com/STMicroelectronics/STM32N6-GettingStarted-ObjectDetectionFollowing the steps provided in the workshop:- https://www.youtube.com/watch?v=29EUWNwfywI&list=PLTJzs51NlEICI7ARAHOyUqMhTgJE0UFv0&index=6- https://www.youtube.com/watch?v=VV9f5e3nqM4&list=PLTJzs51NlEICI7ARAHOyUqMhTgJE0UFv0&index=7---However, after I was able to execute it at first, I tried to conv

I'm currently tinkering with the BLE_Ota example for the P-NUCLEO-WB55.Nucleo and created a debug build spec for it. The default linker script is /* Specify the memory areas */ MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 28K RAM1 (xrw) : ORIGIN = 0x20000008, LENGTH = 0x2FFF8 RAM_SHARED (xrw) : ORIGIN = 0x20030000, LENGTH = 10K }but the image built with the debug build spec is larger, so the length of the flash area to use must be adjusted: /* Specify the memory areas */ MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 32K RAM1 (xrw) : ORIGIN = 0x20000008, LENGTH = 0x2FFF8 RAM_SHARED (xrw) : ORIGIN = 0x20030000, LENGTH = 10K } that made me wonder, is it possible to define constants in the build specs such that conditional statements (e.g using the

Dear all,I'm in the process of converting a convolutional neural network from quantized ONNX format to run on the STM32N6 Neural ART NPU, using the STEdgeAI tool. I do not have access to external RAM on our custom hardware, so everything has to fit in the NPU's RAM (AXISRAM3 to AXISRAM6). However, I found it frustratingly difficult to do so using the STEdgeAI CLI. Using just the default options results in a model that takes roughly twice as much RAM as would theoretically be needed to store the activations (and in some extreme cases even 10x as much).So my question is: are there any tips, tricks, or tools or other command line options that are useful when trying to squeeze a model into the small internal RAM? It looks like the "out-of-the-box" options to STEdgeAI-CLI prioritize execution speed over RAM usage, which is of course unfo

I am facing difficulties configuring the GPO interrupt on the ST25DV04KC to trigger exclusively when an NDEF message is written to the tag via the RF interface. The NDEF formatting is working correctly, and I am able to read and write data without issues both through the RF interface and via my microcontroller using the I2C protocol. However, I have not found a configuration or register setting that allows the GPO to generate an interrupt solely upon an NDEF write event initiated from the RF side.The interrupts are only working if I configure them as shown below.NFC07A1_NFCTAG_ConfigIT(NFC07A1_NFCTAG_INSTANCE, ST25DVXXKC_GPO1_ENABLE_MASK | ST25DVXXKC_GPO1_FIELDCHANGE_MASK);However, in this configuration, as expected, the interrupts are triggered simply by bringing the RF device close to the tag, without performing any read or write request. Therefore, this behavior does not serve the intended purpose.I tried the configurations below but was n

I'm having a persistent /!\-icon sticking to my project icon. It's annoying. How can I get rid of this? I cannot see another such icon attached to any object in the project tree branches, if I didn't overlook any.The project builds without any errors. 

Hello. I am currently developing a board using the stm32f411ret6 chipset. I confirmed that the first firmware download worked properly on one of the boards I am developing. However, after attempting to download the second firmware, I encountered an issue where the option byte was displayed as 0xFF. I tried changing the option byte in various ways, but all attempts failed. Furthermore, I attempted to boot using the system bootloader, but it failed. Could the flash memory itself be damaged?   Below is the link to my initial community inquiry. https://community.st.com/t5/stm32-mcus-products/what-is-the-way-to-fix-stm32f411re-option-bytes-0xff-error/m-p/832817#M284580   Thank you *This post has been translated from Korean to comply with the ST

Hi guys, I have a STM32 NUCLEO-H753ZI board and the overall goal is to run open62541. In order to do that, I need a working LwIP stack and Ethernet connection. I have done a lot of research and tried multiple settings, but can´t get it working. Below, I´ll describe what I have done so far / settings in the .ioc I have made.It would be awesome if you could tell me, where my mistake is.  Using STM32CubeIDE Version: 1.19.0 Build: 25607_20250703_0907 (UTC). Clock Configuration:Input frequency = 8MHz -> PLL Source Mux = HSE -> System Clock Mux = PLLCLK (Enable CSS) -> SYSCLOCK = 400 MHz -> D1 CPRE Prescaler = /1 -> 400 MHz -> HPRE Prescaler = /2 -> 200 MHz-> D1 PPRE, D2 PPRE1, D2 PPRE2, D3 PPRE = /2 System Core:RCC: HSE = BYPASS Clock SourceLSE = Crystal

Hello everyone,I would like to use the VND5T016ASP-E high-side driver in my design.For one board, I need to use 12 of these ICs.I have reviewed the application note; in your opinion, which configuration should I use for this IC to have fewer EMC issues?Also, would it be a problem if I share the FR_stby pins among these 12 ICs?Thank you.

Hello, I am using STEVAL25R200 evaluation board and integrating read/write application using the ndef_read/write examples provided in the documentation embedded library. In my main function, I am Initializing the NFC using rfalNfcInitialize(), rfalNfcDeactivate() and rfalNfcDiscover(). In the while loop, using the rfalWorker() function, I am polling for NFC tags. I have checkd using the EVAL GUI software that a NFC V tag in indeed present and being detected along with its ID (e002080ab3e64bc8).However, the tag is not detected in my code. I get the rfaNfcGetState = RFAL_NFC_STATE_POLL_TECHDETECT on my serial terminal and then it waits indefinitely. In my opinion, the activation of tag needs to happen using Interrupt routine but it never gets called and I never even proceed further. I have set my IRQ (PA0) and SS (PB0) pins in nfc_conf.h and initialized the IRQ pin as follows.#define BUS_SPI1_NSS_GPIO_PIN GPIO_PIN_0#d

I am using custom board with STM32G030F6P6.  Used Cube Mx to generate code with LL  library. Interrupts not working,  I need to add this SCB->VTOR = FLASH_BASE; in main.c  Even after this also ADC DMA interrupt wont work. Need to rewrite the ADC_Init() to get it work. Just keeping you informed. Same thing happened with STM32G030C8T6 also    

Dear ST Developer Support,How to enable MIPI DSI panel on STM32MP257F-EV1?Does it have any user guide for reference?I only found dsi to hdmi board on device tree.I urgently need your help! Thanks.

I'm creating an I3C target device.  It uses an STM32U385RG as the microcontroller.  According to the reference manual most bits of the Provisional ID are fixed and cannot be configured.  This doesn't seem to allow for creating an I3C target device using my own MIPI manufacturer ID.  Is that correct?  Or is there some other way to provide a fully customizable Provisional ID?If not configurable this seems like it makes the Provisional ID useless as it will be identical for all I3C target devices from all designers at all companies...

I'm trying to figure out why the value 4.2 is returned as -2 when passed as a function argument. Could you please also provide a solution? The MCU is an STM32F302VET.
