Solved

I have an XCore407I board with an Ethernet port installed. I'm trying to create a simple UDP server in Stm32CubeIDE. Compilation and uploading to the board is OK. But the board doesn't respond to ping and isn't visible in the router's device list.Here are my settings in IDE.Spoiler (Highlight to read)Here is the main code.int main(void) { HAL_Init(); SystemClock_Config(); /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_LWIP_Init(); // Udp init function udpServer_init(); while (1) { MX_LWIP_Process(); } }Unfortunately, I can't attach the entire project here. But I can add code from other modules upon request.Can you tell me how to set this up correctly so it works? Thank you.

Dear Gfx Team, 1. Could you please consider adding project setting to automatically delete ./touchgfx folder when Designer exits or project closed (Ctrl+Q) ? The folder's size is nearing 300Mb. I have tried many Designer Examples and they consume a lot of disk space because of ./touchgfx folder. This would mirror auto copy of the "./touchgfx" folder into project if not present. Something like this:     2. Idealy, option to set to auto delete "./simulator/msvs/.vs" folder as well would great as it is often even bigger than ./touchgfx.   Thank you.

I've got a custom board with an STM32MP135AAE3 talking to an eMMC (THGBMTG5D1LBAIL if it makes a difference). I've discovered that if I write from SYSTEM to the eMMC using DMA (HAL_MMC_WriteBlocks_DMA) it works fine, but if I use anything in RAM (SRAM1, SRAM2, or SRAM3) as the source, the DMA fails immediately.If it helps, the SDMMC2 registers inside SDMMC2_IRQHandler() are: STA=0x8001010; DCOUNT=0x200; DCTRL=0x90; IDMACTRL=0x1; MASK=0x11AIs this a known limitation of the IDMA? If not, is it something I'm somehow initializing incorrectly?

I'm trying to generate code using CubeMX for the Nucleo-U031R8 demo board to output a clock signal to the MCO2 pin. But the generated MX_GPIO_Init function makes the following assignment:GPIO_InitStruct.Alternate = GPIO_AF0_TRACE;Naturally, the compiler throws an error: "GPIO_AF0_TRACE undeclared".If I manually change the code to the following:GPIO_InitStruct.Alternate = GPIO_AF0_MCO2;...the code compiles without errors.Is it possible to fix this bug in the next CubeMX release?

Hello,We completed a test of bi-driectional communication of the Proprietary Packet feature (PP) for a mass market client using the STWLC38 (RX) and STWBC86 (TX).We're able to consistently receive the data of 5 bytes reliability from the RX to the TX. In the other direction though, we haven't gotten it to work as the existing bi-directional communication PDF is well, not very specific. On the RX side of things, the message buffer at 0x0190 is always filled with 0's, even though 0x0088 interrupt bit 5 (RX MSG RCVD LTCH) is set to 1. The document states"The difference here is that STWBC86 does not add the checksum automatically, the user must provide it with the message. The checksum is calculated as a XOR of the message bytes, including the header."So we assume the message is then constructed as (first byte sent): 1 byte header, 5 bytes message, 1 byte xorThe header is set to 6f in this case, not 5f (?)0x6f, 0x11, 0x22, 0x33, 0x44, 0x55, 0x7e When the message is insp

I have watched ST's offical YouTube series about bootloder and  I found it very clear and helpful.That series: https://www.youtube.com/playlist?list=PLM7yYW7w7MWms-Um-dHxbftXRUFT74u9lI was able to understand the general workflow and main ideas. However, I still feel that I have some missing points, especially the pratical and low-level details.I am a junior embedded software developer and I would like to properly learn bootloder and OTA update concepts from the ground up.That's my questions are here : 1) From which topics should a junior embedded developer start in order to understand bootloader and OTA mechanisms correctly ?2) What fundemental topics should I focus on first ?3) I have several discovery and nucleo boards, and my goal is to implement a very simple bootloader or OTA demo on one of them. Any guidance, recommended learning path or simple example project suggestions would be greatly appreciated.Thank you in advance.

Hi everyone, I’m asking for your help with accessing my SD card. I’m running into an issue with the STM32N6DK750 Discovery Kit and would really appreciate some advice. I’m trying to write data to an SD card using FileX and ThreadX. Everything compiles and debugs fine, but nothing actually gets written to the card. I also tried the FX_MultipleAccess example provided by ST, but it doesn’t compile. I’ve tried fixing several compilation errors, but some declarations are missing, like byte_pool in app_filex.c. I’m not sure what’s causing the issue, and I’m wondering if I might have missed an important step or misconfigured something.

Hi! I am working on creating a new build system for my for a software platform using CMake to help with management of different targets and toolchains. I have an .ioc file that is currently in use with the existing build system based on CubeIDE that contains all middleware (FreeRTOS, LwIP, TouchGFX) additions and configurations, so I am not changing anything. I am trying to make the build as modular as possible so I am trying to link the stm32cubemx and touchgfx CMake targets directly. I am using build presets to manage configuration. Creating the build system works fine, but when I try to run the build I get compilation errors because the TouchGFX related files can't find the user constants defined in CubeMX for TouchGFX, as shown below: This can be expected because these symbols are created in defines on main.h and the TouchGFX file being referred there does not include main.h. I could add it manually, but I'd like to try to get the system to work directly from autogen

Hi,When opening a CubeMX-generated project in VS Code for the first time, a popup appears that—according to ST’s tutorial—you’re supposed to confirm by selecting “Yes”.Unfortunately, the popup disappeared after a few seconds before I could click it. I’ve tried reopening both VS Code and the project, but it hasn’t appeared again.How can I bring this popup back, or trigger the same setup manually?Thank you  

Hi,I'm developing a camera interfacing application. I've used GPDMA in linear-circular mode. But, now I have to handle larger resolution(640x480). Is there any application example from where I can start configuring DMA in CubeMx?

Hello,I had windows 10 and the CubeProgrammer was without problems.Now, on this PC with new windows 11 when I try to open file (hex, srec) in Erase & Programming  with Browse then a new windows is opening and after I can't choice my file and STM32CubeProgrmmer is closed.I tryed in administrator excecution but the problem is always.I looked this problem on all the windows with open file. Could you help me , please?Best regards  

Hi, I'm designing the board for STM32H755IIK6. My power supply plan is SMPS + LDO, since I want to use 480MHz speed.  I wonder if there are better recommendations about 2.2uF VCAP placement. There are three VCAP pins, but two 2.2uF capacitors are instructed to use in reference design. On the other hand, capacitors should be placed near VCAP pins. So how to place two capacitors near three pins A4, A14 and R13? It looks like MB1520 does not have capacitor near A14. Is that correct implementation?

When I write code, should I keep the microcontroller on, or turn it off and only turn it on when I want to test the code?

Hi,we are using the STM32H7R7I8T6 MCU with an Infineon S70KL1282 HyperRAM Chip attached on XSPI1 and configured via CubeMX, we are looking for an example for the correct timing/parameters to use the RAM Chip in memory mapped mode as Graphics RAM.Our current config makes makes reading and writing possible but the memory contains garbarge data.We are repeatedly trying to write the string "1234567890" into the external RAM but we get back the following:The current config is built from various other examples we could find like this one: https://github.com/STMicroelectronics/STM32CubeH7/blob/master/Projects/STM32H735G-DK/Examples/OSPI/OSPI_HyperRAM_MemoryMapped/Src/main.c but the parameters do not match exactly. Our current code looks like this:/** * @brief XSPI1 Initialization Function * @PAram None * @retval None */ static void MX_XSPI1_Init(void) { /* USER CODE BEGIN XSPI1_Init 0 */ /* USER CODE END XSPI1_Init 0 */ XSPIM_CfgTypeDef sXspiManagerCfg = {0}

Hi, I know that currently STM32WB0 is the only family of BLE MCU that currently supports BLE PAwR, but this MCU is very limited in terms of on-board peripherals, RAM and other features. The STM32WBA series looks like a promising candidate for one of our upcoming projects (industrial sensor nodes application), but unfortunately it seems it does not support PAwR. So I wanted clarity on if there is any plan to support PAwR in the near future on STM32WBA chips? Best Regards,MCM

Hello ST Support Team,I am reporting a regression issue with the latest STM32F0xx Device Family Pack (DFP) version 3.1.1 when used with Keil MDK 5.43a.Problem Description:Installation Issue: The DFP 3.1.1 often fails to install via the Pack Installer, showing validation errors or failing to resolve dependencies.Missing Registers: Even when successfully installed, the System Viewer in Debug mode is empty.

I have a question about writing to the STM32F410's FLASH.I'm creating a program to write data received via USART to FLASH, but it's not working correctly.The writing to FLASH itself is happening, but the written data differs from what I expect.This different written data contains a large number of “0xAA” values that are not present in the original data.Do you know what might be causing this phenomenon?void FLASH_UNLOCK(){ while ((FLASH->SR & FLASH_SR_BSY) != 0){ } if ((FLASH->CR & FLASH_CR_LOCK) != 0) { FLASH->KEYR = 0x45670123; FLASH->KEYR = 0xCDEF89AB; } } void FLASH_DELETE(uint32_t address){ while ((FLASH->SR & FLASH_SR_BSY) != 0){ } FLASH->CR |= FLASH_CR_SER; FLASH->CR |= (FLASH_CR_SNB & 0x8); FLASH->CR |= FLASH_CR_STRT; while ((FLASH->SR & FLASH_SR_BSY) != 0){ } if ((FLASH->SR & FLASH_SR_EOP) != 0) { FLASH->SR |= FLASH_SR_EOP; } else { } FLASH->CR &= ~FLASH_CR_SER; } void FLASH_Write

I’m a beginner with TouchGFX, and I’m wondering whether it’s possible to make touch input behave the same way it does on mobile smartphones. Specifically, before a drag event is detected, the finger must move a certain number of pixels.What I’d like is this: when a press event is first detected, you check whether the user has moved their finger at least 10 pixels, and only then do you start moving the screen. However, once that threshold is reached, the screen should move starting from 1 pixel. When the user releases their finger, a release event occurs and everything is reset, so that after the next press event, the finger must again move 10 pixels before a drag event can occur.Is it possible to implement this behavior? I tried using setDragThreshold, but then the entire screen scrolls by the number of pixels specified as the threshold. Is it possible to change setDragThreshold dynamically in the view?

Hi,I am using the X-NUCLEO-NFC09A1 with the demo project “ST25R200_v3.0.0_Linux_demo_v1.0”.The code is running on a Raspberry Pi 3B and communicates with the reader via SPI.When I run the demo and place an NFC tag near the reader, the application reports “READ Fail”.Could someone please explain what this error means and what might cause it?Thank you.

Hi, I have been working on a project that is based on the ST25R3911b Discovery Board including building prototype firmware from the discovery kit's firmware. I have made sure not to edit any of the RFAL or HAL library files.Recently I had brought this prototype to be pre-scanned for radiated immunity. During this testing, I discovered a bug that I have not seen before.The process gets stuck in an infinite loop in the rfalTransceiveRunBlockingTx() function (found in rfal_st25r3911b.c).Specifically on line 1267, while( (rfalIsTransceiveInTx() && (ret == ERR_BUSY)) );In the rfalTransceiveTx() function, the process enters the RFAL_TXRX_STATE_TX_WAIT_TXE case and checks for interrupts. However, there will not be any interrupts to process, and so the process breaks without updating the gRFAL.TxRx.state.This appears to me like the interrupt from the NFC chip was either not sent or was not received correctly, so when that Do while loop checks "(ret == ERR_BUSY)", it will always be

I'm migrating from Windows to Linux (Ubuntu 22.04) as my main OS, and I'm setting up the STM32CubeIDE for development.  I noticed that the Linux install of STM32CubeIDE (v2.0.0 downloaded from this site) is missing almost all of the ST specific features that make using the IDE worth it for me.  Is there a reason for this?  Is there a way to install these after the fact?The ST specific features I'm speaking of are the integration of STM32CubeMX and ability to generate all the initialization code for the various peripherals that I'm looking to use.   Specifically: I'm looking for the Linux install to have an option of File > New > STM32 Project, which then gives me the option to select a board (Nucleo, etc.) or a bare MCU (STM32U575xxx, etc). It then generates a .ioc file and eventually generates the code.

We have a design that has been working fine for some time now using STM32G071CBT6 in LQFP48 but a new batch is suddenly failing with ADC readings from VREFINT that are quite a way out of spec.Previous versions have always been slightly low - reading maybe ~3.15v on a ~3.25v supply voltage but that's always been "close enough", but now the latest batch of devices are dipping below 3.0v on the same ~2.35v supply and triggering our under-voltage detection.We are monitoring a few voltages using the ADC, including the supply voltage which is commoned with VDD/VDDA, VBAT and VREF pins - decoupling is per the power supply scheme shown in the datasheet DS12232.VREFBUF is disabled.Since we are not worried too much about absolute accuracy, we are not running the calibration routine on the ADC.System clock is 16MHz and ADC sampling is 79.5 cycles, ADC resolution is 12 bit.The ground pin is solidly grounded, supply voltage going into the pins is ~3.25v and I can't see any significant current being

Hi everyone,I’m building a coffee machine project using STM32C071 (C0) mainly because it has USB. I need USB Host MSC to:Mount a USB flash drive (FAT)Read/write files (params/logs)Firmware update from USB driveThe “official” ST stack seems to be ThreadX + USBX + FileX. Since there’s no USB Host MSC example for C0, I used an STM32L4R5 example (much larger RAM) as reference and adapted it.Issue: To pass ThreadX/USBX init, I kept increasing stacks/pools until I’m using ~20 kB of RAM. Then, when I plug the flash drive, enumeration fails with out-of-memory errors (e.g., UX_DEVICE_ENUMERATION_FAILURE / allocation failure).Questions:Is ~20 kB RAM just to init (and still fail at enumeration) expected for USBX Host MSC + FileX, or does it strongly suggest misconfiguration?Is there any official guideline/table (ST/Azure RTOS) for typical/minimum RAM for USBX Host + MSC + FileX (FAT)?Is there a practical RAM “floor” to enumerate + mount FAT + read/write files (single device, no HUB)? Like “below
