I have develop a program on STM32F746G-DISCO revision B02 with QSPI  N25Q128A13EF840ENow the new boards revision C03 use the QSPI W25Q128JVEIQ.I have copied the file W25Q128JVEIQ_STM32F746G-DISCO.stldr from CubeIDE 1.16 to the STM32 ST-LINK Utility\ST-LINK Utility\ExternalLoader but the external loader is not flash.I need to change some in my code to use this new QSPI chip ?  

Hello STM Community,I'm currently working on a project involving the ST25DV04KC-IE8C3 NFC chip interfaced with the STM32L496ZG microcontroller. I've encountered an issue where the performance of the NFC chip deteriorates when a magnet is brought near the system, specifically related to the operation of a magnetic switch that generates interrupts.Problem Description:Components: The NFC chip is located approximately 3.6 mm away from a magnetic switch (RR132-2E32-551).Issue: When the magnet is brought close to the magnetic switch, it appears to cause delays in counting and issues with I2C communication. Specifically, I suspect that the magnetic field is affecting the NFC chip's operation, leading to unexpected behaviour or interruptions that impact the STM32’s performance.Effects on System:Interruption in the NFC communication.Possible noise was introduced on the I2C bus.Delays in processing and timing, particularly in counting routines.Troubleshooting Steps:I’ve monitored the interrupt l

Hello, I am getting up and running with the STM32 ZeST Kit to evaluate the HSO capability. Components: 1) STEVAL-LVLP012) B-MOTOR-PMSMA13) B-G473E-ZEST1SI am currently on MDSDK 6.3.1, and Motor Pilot V1.2.11 (MC_FOC_ZEST). I was able to successfully build a profiler project in the workbench, flash it with the CubeIDE, and profile the motor in Motor Pilot. The HSO Start Up Guide provided in the MCSDK 6.3.1 release notes were helpful to this point. I am now looking to tune the current and speed PI gains. My issue is finding the "Rev-up" section for generating speed or torque profiles to play for tuning these gains. Maybe I'm missing something?Is there a document similar to the HSO start up guide for this part? Or is there a section in Motor Pilot I am missing?The motor pilot start up guide seems to still reference MDSDK 6.2.1 and Motor Pilot V1.1.13. https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:STM32_MC_Motor_Pilot_-_Start-up_guide#Rev-up_configu

Hii, have installed motor control workbench and i have stevalspin3202 evaluation board, in motor control workbench while generating code it showing error also i have opened the stm32cubemx and when it completed it is telling completed with error how to solve this issue also i have attached the log file of it. 

Hi Guys,I have a problem with erasing Flash sector. I am using STM32F746ZG Nucleo Board. When  I run this code, mcu works perfect it works but I can't install new firmware to mcu. I've also tried example code, same problem. I take (DEV_TARGET_NOT_HALTED) when I run the program.I am getting the same error in debug mode as described in the link below.https://community.st.com/t5/stm32cubeide-mcus/how-to-solve-error-finishing-flash-operation-in-stm32cubeide/td-p/53113/page/2Code Here they are FLASH_EraseInitTypeDef FLASH_Erase_Init; uint32_t SectorError; HAL_FLASH_Unlock(); FLASH_Erase_Init.TypeErase = FLASH_TYPEERASE_SECTORS; FLASH_Erase_Init.VoltageRange = FLASH_VOLTAGE_RANGE_3; FLASH_Erase_Init.Sector. FLASH_SECTOR_3; FLASH_Erase_Init.NbSectors = 1; if(HAL_FLASHEx_Erase(&FLASH_Erase_Init, &SectorError) == HAL_OK) HAL_Flash_Lock();  How can i solve it ?

For the life of me I cannot get the I2C pins on my microcontroller to output anything.I am using I2C1 on pins PB6 (SCL) and PB9 (SDA) on the STM32F746VGT microcontroller. The pins are hooked up to a TXS0108E level shifter that has built-in pull up resistors. I have a very simple CubeMX project that initializes I2C1 to Standard Mode and attempts to transmit some data on it every second.All I want to see are some signals on the SDA/SCL lines but I get nothing. I can change the I2C pins to open drain GPIO pins and toggle those and see it on the scope, but when I switch back to I2C I see nothing again.I see the lines stuck either low or high depending on which one I'm probing at the moment. If I reset the MCU then probe the lines, they're both stuck high. They're also stuck high if I reset the MCU while probing SDA. But if I reset the MCU while probing SCL, then both lines get stuck low. So it seems like my oscilloscope has an effect on the transmission. Not sure if that's relate

Hello Everybody,MCU: STM32H750XB (STM32H750DK Discovery Kit)FDCAN Clock : 40MHzI'm experiencing an issue with my FDCAN bus configuration where the node enters Error state and issue persists with any data rate higher than the nominal rate of 500 kbps.But it works under Nominal Bit Rate: 500 kbps Data Bit Rate: 500 kbps.QuestionsIs there a known limitation with running data bit rates higher than nominal bit rates on the STM32H750?Are there specific timing parameters I should adjust for higher data bit rates considering the FDCAN clock as 40 MHz?Below,I have attached the main.c and IOC files for your reference.Regards,Dev 

Hi folks,   I need to use setup system where is 10BASE-T1S communication. And we have stm32H7 controller, so questions is which one would better use LAN8651 (MAC+PHY) chip and do controlling of chip via SPI or chose LAN8670 (PHY) and do chip controlling via RMII. If I have understand right there is no ready drivers for stm32 MCU so probably have to write own drivers from scratch. Do you know Is there some good codebase which can modify to fit to STM32 ?

Hi there TouchGFX team! I need to do a fade out animation when changing from my welcome screen to my home screen, but I can only see 4 options on TouchGFX designer. I suppose I need to change the alpha value, but there's several widgets on each screen, so I'm not sure updating each one of those alpha values is the best approach. How can I implement it? Thanks a lot in advance

Hello, I am working on a diy simracing project which use the STM32F401CCU6 board. I just bought this board and It worked fine until today for a reason I ignore. The board is stuck on the red led, the blue led doesn't light up anymore. I can still find the board in the device manager ( picture under ) but not it is not detected as it shall be in game controller configuartor ( picture under ). I can still erase the sketch on STM32 Cubeprogrammer and upload it but when I disconnect it it stays with the red led.Have anyone any idea on what to do ?Thanks you for your answers, and sorry for my english which isn't very good !   

I'm trying to use the RAMECC monitoring subsystem on an STM32H743 but there's some behaviour I don't understand. I've read the reference manual (RM0433 rev 7) and application note AN5432, as well as some related forum posts here.If I set an interrupt enable bit in one of the RAMECC_MxCR registers then I get interrupts even if none of the interrupts are enabled in RAMECC_IER.So it seems like the interrupt enables in RAMECC_MxCR are independent of the per-monitor interrupt enables in RAMECC_IER.Is this the intended behaviour? It's unclear to me from the reference manual and AN5432.

Hello,I am new in TouchGFX and I like it. But now I have a problem:I am trying to make a ScrollList with a variable number of items. To do that, I made in TouchGFX a ScrolList with number of items: 1  and a height of 50 which is the height of 1 item. The generated code is  scrollList1.setPosition(40, 200, 400, 50); scrollList1.setHorizontal(false); scrollList1.setCircular(false); scrollList1.setEasingEquation(touchgfx::EasingEquations::backEaseOut); scrollList1.setSwipeAcceleration(10); scrollList1.setDragAcceleration(10); scrollList1.setNumberOfItems(1); scrollList1.setPadding(0, 0); scrollList1.setSnapping(false); scrollList1.setOvershootPercentage(75); scrollList1.setDrawableSize(50, 0); scrollList1.setDrawables(scrollList1ListItems, updateItemCallback); add(scrollList1); In the  setUpScreen(), I change the following void Screen4View::setupScreen() { uint16_t elements; uint16_t height; uint16_t windowsize; elements = presenter->NofThick()

Hey there,I am using the CubeProgrammer API (2.17.0) to flash a STM32U545 MCU over USB DFU with a new firmware.When doing so a write error occurs (downlaodFile(...) returns CUBEPROGRAMMER_ERROR_WRITE_MEM (-10)) when flashing a new hex file (when using the same hex file as already on the MCU no error occurs).Flashing the hex file using the CubeProgrammer application (via J-LINK) works fine.Also a full chip erase, so no write protection active.My code: CubeProgrammer::dfuDeviceInfo* dfu_list = nullptr; int count = CubeProgrammer::getDfuDeviceList(&dfu_list, 0xdf11, 0x0483); CubeProgrammer::connectDfuBootloader(dfu_list[0].usbIndex); int FirmwareStartAddress = 0x08000000; unsigned int verify = 1; // verify download unsigned int skip_erase = 0; // do not skip erase CubeProgrammer::cubeProgrammerError result = static_cast<CubeProgrammer::cubeProgrammerError>( CubeProgrammer::downloadFile(file_path, FirmwareStartAddress, skip_erase, verify, L"")); When skipping the ve

Hi everyone,I'm using an STM32G431KBT6 MCU (STM32G4 Series) and I'm trying to generate a sine wave of 1 kHz using   DAC and  DMA . I've initialized the DMA as a half word, but it's not creating a sine wave. When I switch to word, it works perfectly. Can anyone help me figure out what's going on?My SYSCLK is at 16MHz.

I'm trying to write a block ( 4 bytes) of normal memory from RF (via an Android) using command 0x21.I can do this with Vcc OFF, no problems.I also need to write to the Mailbox (command 0xAA), but to do this I have to have Vcc ON (obviously the I2C can't read that message without Vcc).The Write Block (0x21) returns 2 bytes, 0x01 0x0F, which is "unknown error".What do I need to do/set to allow the RF Write Block to work with Vcc ON?Many thanks in advance, gurus!

HI,we are interested in a guide to  a clear workflow of integrating CubeMX-generated code for U5 into TFM-based application.In particular:1. We have trustzone-enabled CubeMX-generated app with Azure RTOS and TouchGFX. The IDE and compiler are IAR. We want to be able to easily debug and re-build it, as needed, without any much security involved and, even most important, without manipulations with flash loaders and signed binaries every time a single line of code gets changed. 2. Once we are happy with stable code behaviour, then we want to "wrap" it in TFM, by letting the latter to create signed binaries and the loader, as per TFM example for U5 from STM. If any intermittent step((s) required to achieve so: adjusting addressees, locations, etc - we are OK to create custom pre/post builds ourselves. But we'd like to know what exactly steps are needed. So the questions are:a). Is there any help/guide/examples or any other support can be expected from STM for that matter?(Ye
