Solved

Hello; I am very new to STM32 products. I have been working with the P2P_Server and P2P_client examples using the STM32WB05KZV6TR MCU.As I use the P2P_clent example in both the Nucleo board WB05KZ and a custom board and load the built image, the next time I try to download a new image I need to put the nucleo board into Bootloader mode(BOOT0 jumped to Vcc) and download the new image that way. The custom board that I am working with currently has no hardware way of putting it into bootloader mode therefore I cannot load a new image.My question is, why do I need to put the nucleo board into bootloader mode to load an P2P_Client image?, The P2P_server does not have this issue Is there a way to prevent this? thanks Fernando

My linked-list object's base address in memory is 0x200bffbc.   How can I save this address in GPDMA_CxLBAR register (that holds "the linked-list base address of the memory region, for a given channel x, from which the LLIs describing the programmed sequence of the GPDMA transfers, are conditionally and automatically updated")  when GPDMA_CxLBAR designated region for the address (LBA[31:16]) is only 16 bits long? Anyone can help please? 

Hello everyone,We constantly receive orders from our customers that they got some motors which their nominal speed, nominal voltage, and etc. are approximately similar to each other, but their Rs, Ls, Ke, and pole pairs may differ.They want us to design an inverter board in such a way that it can get these motors running, providing the capability to see if their motors are damaged or not, just by using a single board without the need to customize the firmware or the hardware for each motor. So, we need to somehow get pole pairs of the motor from the user, change it in the firmware and run the profiling process.For such purposes,What can we do by using ST motor control workbench?What are the related APIs to achieve this goal?Is this even possible?Thank you!

Hello everyone. Question about synchronous launch of three timers.Given:- CPU F0 or F4 or G4 (of course F103 is possible - I just don't like it, personal dislike);- three timers, each with its own operating frequency, Timers work via DMA, each with its own buffer for PWM generation;Task:- simultaneous launch of all three timers;Limits:- interrupts are prohibited, no interrupts;With the same frequency - there are no problems, they start at the same time, but with different frequencies, everything diverges. Tell me if there is a solution.

I feel duped right now.  I bought the P-NUCLEO-LRWAN3 kit yesterday from st.com directly as my starting point into embedded stuff. Today I installed CubeIDE and went to generate a new project for the NUCLEO-F746ZG included in the kit, and I get a message telling me the board is obsolete. The kit says the marketing status is "active", but when I look up the NUCLEO-F746ZG directly, sure enough it says it's obsolete and I should use the NUCLEO-F756ZG instead.Why is this package marked as active and still in circulation? I feel this is just a way to sell obsolete boards to people don't know any better. Yeah I should have looked up the each board in the kit individually before buying, but I guess I was just burned out from researching all these different boards and I decided to trust that the kit is legit. edit: Maybe the wrong board is listed in the kit description?  I hope that's the case.  It's due to arrive on Monday, so I guess I'll see then.

Hi there,I have the following setup duplicated thrice in my project - to select three distinct parameters to define an object.Each listLayout is programmatically populated with a number of items (buttons). One screen has 5 items, the other two have 6. Five items fit perfectly on a screen and don't require a scrollbar, while six items require scrolling to see the final item. However, none of the scrollableContainer display their scrollbar until I touch the screen, despite me configuring it to do so (at least, that's what I think "Show scrollbars" means):What am I doing wrong? How can I ensure that the vertical scroll bar is shown, by default, when I open a screen with more items than fit on a screen?Thanks,Julia 

Hey everyone, I'm working with the STM32H747I-DISCO board and trying to get it into USB DFU mode to flash firmware using STM32CubeProgrammer. However, the board isn't being detected, and I couldn’t find clear instructions in the documentation about how to properly enter DFU mode. If anyone has managed to get this working or knows the correct steps, I'd really appreciate your guidance. Thanks in advance!

Hi,With the latest STM32CubeIDE 1.18.0 (I tried on Mac and Windows), on a brand new project for a STM32H7B0VBT6 mcu. In the ioc, if I try to enable the SAI1 (or SAI2) it let me choose the mode for both SAI A and SAI B but the configuration panel is empty, it also shows a spinning icon when clicking on SAI1 again. I attached a screenshot for reference. Everything else seems fine (I2S, I2C, SPI, ADC, etc).Any help is welcome! Thank you!

I plan to transmit stream of approx 10k characters by uart every second. For that purpose, I have definer global char array of 10.5k length. After working for few second, the MCU goes in HardFault.I tried with array of 1000 bytes only, it works fine. But as I increased to 10k bytes array, problem start coming.Should I change stack sizes in linker file. ? please suggest and where to change.  

I would like to file a bug report for STM32CubeMX.During configuration of CORDIC using DMA, I have found the following issue:In:void HAL_CORDIC_MspInit(CORDIC_HandleTypeDef* hcordic) { if(hcordic->Instance==CORDIC) { /* USER CODE BEGIN CORDIC_MspInit 0 */ /* USER CODE END CORDIC_MspInit 0 */ /* Peripheral clock enable */ __HAL_RCC_CORDIC_CLK_ENABLE(); /* CORDIC DMA Init */ /* CORDIC_WR Init */ hdma_cordic_wr.Instance = DMA1_Stream0; hdma_cordic_wr.Init.Request = DMA_REQUEST_CORDIC_WRITE; hdma_cordic_wr.Init.Direction = DMA_MEMORY_TO_PERIPH; hdma_cordic_wr.Init.PeriphInc = DMA_PINC_DISABLE; hdma_cordic_wr.Init.MemInc = DMA_MINC_ENABLE; hdma_cordic_wr.Init.PeriphDataAlignment = DMA_PDATAALIGN_WORD; hdma_cordic_wr.Init.MemDataAlignment = DMA_MDATAALIGN_WORD; hdma_cordic_wr.Init.Mode = DMA_NORMAL; hdma_cordic_wr.Init.Priority = DMA_PRIORITY_LOW; hdma_cordic_wr.Init.FIFOMode = DMA_FIFOMODE_DISABLE; if (HAL_DMA_Init(&hdma_cordic_wr) != HAL_OK) { Error_Handler();

Hello,I got a error message during control project genaration"It is not possible to create a motor control project with the FOC algorithm using the selected hardware. No proper path for motor control signals was found for the following mandatory features: - Phase Voltage Generation - Current SensingFor more details, please, look at the following log file in your home directory: .st_workbench/connectAlgo.log", but it was unable to find connectAlgo.log in the folder \AppData\Local\STMicroelectronics\MC_SDK_6.3.2\Utilities\PC_Software\STMCWB\.

It looks like this commit reverted the hashes for meta-st-stm32mp-addons and meta-st-scripts.The revert for meta-st-stm32mp-addons is particularly problematic because the commit pointed to by the v6.0.2 manifest has LAYERSERIES_COMPAT_stm-st-stm32mp-mx = "mickledore", which breaks the build for v6.0.2, which requires "scarthgap". Am I missing something?

It is really sad that ST decided to not implement this requested and really helpful feature: https://github.com/STMicroelectronics/STM32CubeG4/issues/23Maybe we can change their minds by creating some more attention to this topic here? Leave a comment, when you also find this useful ;)Example solution for the I²C driver by adding a void* to the handle:  typedef struct __I2C_HandleTypeDef { /* Rest of struct... */ #if (USE_HAL_CALLBACK_CONTEXT == 1) void *UserContext; #endif /* USE_HAL_CALLBACK_CONTEXT */ } I2C_HandleTypeDef;   

Hello, Apologies in advance for the length of this post. I am looking for some advice as I am working on getting a cpp based callback for the VL53L4CD sensor, to do this I have written a file which should perform all the same setup as the driver provided however I am encountering a strange error that I cannot understand.Link to Github with Code, please see: real_time_drivers/VL53L4CD/VL53L4CD_LinuxDriver_V2.3.2/user/uld-driver for all relevant codeWhen I run my own file first, it sets the sensor to always return a status of two even if I then run the example executable (menu) provided as part of the the driver example this also returns a status of two.  HOWEVER, if I run these in the other order the sensor range is printed perfectly by my own program. This status will remain the same for any executable ran after the first and will be overwritten.  I have tried to find a conditional statement that might cause this however I have been unsuccessful in doing s

Hi,Using Wise studio Version: 1.3.1_R Build id: 2023_05 on Linux with the STEVAL-IDB012V1 (BlueRNG-LPS dev. kit). I am trying to make the DMA sending a series of bytes to the lowest byte of the GPIOB output. The goal is to see a binary sequence appear on PB0 and PB1. I filled the buffer "buffer" with values where bit 0 and 1 are changing. Then, I call the two functions depicted below but nothing happens on PB0 and PB1. I already verified that the counter is counting and the GPIO can drive different values on PB0 and PB1. So I think my problem is in the DMA settings.#define BUFFER_LENGTH 1400 #define PERIOD_50_US 3200 // 50us from 64Mhz timer 16 uint8_t buffer[BUFFER_LENGTH]; void My_GPIO_Settings() { GPIOA->MODER =0x000000A0; LL_GPIO_SetPinMode(GPIOB, LL_GPIO_PIN_0, LL_GPIO_MODE_OUTPUT); LL_GPIO_SetPinMode(GPIOB, LL_GPIO_PIN_1, LL_GPIO_MODE_OUTPUT); } void DMA_Based_Waveform_Settings() { // Setting DMA channel MODIFY_REG(RCC->AHBENR, 0, 1); // Enable the clock for DMA and

Hi,TouchGFX does not like spaces in the path. I just wanted to check a couple of things please: 1) that is referring to the/my project path only, is that correct? 2) For those of you who use Dropbox, the Dropbox PC folder name cannot be changed and it always contains the team or person name + a space + "Dropbox". So it seems you cannot have your projects stored on Dropbox. And I would really need to have them there. Are there any workaround? How do you do it? Thank you :) 

Hi,I've lost the power brick for my STM32MP15X-EVAL board. It's a 5v-3a barrel connector, but I don't know the polarity and it's not written on the board or anywhere.Does anyone know where I can find a replacement, or the exact spec of the power brick so that I can find another one ?

Hello, I am designing a card that will use an STM32G474QET6TR and I want to program it using USART. The card will use a USB to USART converter (FTDI4232HL).  The Rx and Tx of the FTDI are connected to pin PA2 and PA3 respectively, as I found in AN2606. My first question is how can I tell my MCU that it is supposed to use bootloader mode ? and Which pattern would be better to use ? Also, regarding the pattern, how do I tell the MCU that nBoot1(bit) is supposed to be a 1 or a 0 ?  I am quite lost regarding how the bootloader works and any docs I've read as made me even more lost ?? So any help provided will be most welcome. Thank you very much    

Greetings - what are the recommended maximum current ratings for the INT pin in either Push-Pull or Open-Drain? And FWIW, I was really surprised NOT to find this published in the datasheet...TIA,-Terry

Hi ST team,We’re using the ST25R3918 in a low-power BLE+NFC product. During testing, we noticed unexpected ~10 µA additional current draw when the chip was in Power-Down mode (with all VDD rails active), despite expecting ~1–2 µA per the datasheet.After isolating all possible causes, we found this behavior:With I2C_EN pulled HIGH (selecting I²C mode), total current in power-down mode is ~13 µAWith I2C_EN pulled LOW (SPI mode), current drops to ~3 µANo I²C or SPI traffic is active at this point — chip is just powered and sitting in default state after POR, even with lines cut.This behavior seems to suggest that I²C mode selection (I2C_EN = HIGH) may keep some internal circuitry partially active, even in Power-Down mode.We’ve decided to move back to SPI mode (LOW), which solves the issue and also allows faster data transfer and shorter NFC "on-time."Is this increased current draw in Power-Down mode with I2C_EN = HIGH expected?Is there any internal I²C block or biasing circuitry that coul

Hello,I’m currently working on NFC detection using the ST25R3917 with Felica.My system configuration is as follows:PC Application ⇔ USB to I2C ⇔ ST25R3917I’m running RFAL in the PC application and have extended rfal_platform.c to control the USB to I2C interface.The current sequence of operations is:1.rfalNfcInitialize();2.rfalNfcDiscover(&discParam);    memset(&discParam, 0x00, sizeof(discParam));    discParam.compMode             = RFAL_COMPLIANCE_MODE_NFC;    discParam.devLimit             = 1U;    discParam.nfcfBR               = RFAL_BR_424;    discParam.ap2pBR               = RFAL_BR_424;    memcpy(&discParam.nfcid3, NFCID3, sizeof(NFCID3));    memcpy(&discParam.GB, GB, sizeof(GB));    discParam.GBLen                =

Hi there,I'm designing a custom PCB using the STM32N657Z0 MCU. The design is extremely space-constrained, so I try to leave out everything I can. Since this deviates quite a bit from the reference design (well, the N6 Discovery kit, that is) I'd love to get some clarifications from someone from ST experienced with the N6 hardware side of things:1. I'm not using USB at all. What should I do with the USB power pins VDD33USB and VDDA18USB, can I just connect them to ground? Or leave unconnected? Are the tuning resistors OTG1_TXRTUNE and OTG2_TXRTUNE necessary when I don't use USB, or can I just leave these pins unconnected? I assume all other USB pins (data etc) can just be left floating.2. I do not use any external crystals or oscillators, can I just leave the OSC_OUT, OSC_IN, OSC32_OUT and OSC32_IN pins unconnected?3. I use an external regulator to supply the VDDCORE domain (instead of the internal SMPS). Am I understanding AN5967 and AN6000 correctly that in this case the pins for the
