Solved

Development Board: Nucleo-L476RG.IDE version: STM Cube IDE 1.11.0For the system watchdog timer, there's an equation(attached.) Is there an equivalent equation for the IWDG ?Any suggestions would be appreciated.Thanks

In the reference manual RM440 Rev7 that register is missing while the register is defined in the SAI_TypeDef. I only found a description in the F446 RM0390. Are they the same?

Hello,we use the system supply configuration "Direct SMPS supply" (AN5419 Figure 2) for the STM32H735VG.We have the following problem in the current hardware design: At pin VLXSMPS an oscillation with approx. 6.4MHz can be measured sporadically (see DS1Z_QuickPrint1) which we cannot get a grip on. The ringing does not occur after each switching cycle (see DS1Z_QuickPrint2) so this is meant sporadically.The following component is used as the inductor L900: 2.2uH/1.8A/116mR DFE201612E-2R2M=P2 Mouser part number: 81-DFE201612E-2R2MP2 The following component from Murata is used as capacitors C913 and C914: 10µF 0402 Low ESR (0.006Ohm@3MHz)GRM155R60J106ME47 ESR diagram: https://www.murata.com/en-eu/products/productdetail?partno=GRM155R60J106ME47%23 The 220pF on the VLXSMPS pin is populated. What can we do to suppress the oscillation? Sincerely Manuel Del Basso

Hello,I am using the NUCLEO-F401RE with the NUCLEO-IDB05A2 bluetooth low energy expansion board. I am trying to run the sample demo code that is part of the X-CUBE-BLE1 software package (SensorDemoBLE). I followed the instructions in this video below:https://www.youtube.com/watch?v=jGljm6nxW9sWhen I follow this video, I am unable to build the project because the build option is greyed out. Additionally, when I try to import the project from the File System or Archive, it shows the Bluetooth_SensorDemo\STM32CubeIDE Exlipse Project is not opened. If I select it and hit finish, it does not do anything. Does anyone know what causes this?STM32CubeIDE Version: 1.11.0STM32CubeMX Version: 6.6.1

HelloI'm working on a F412G-Disco board, with a TouchGFX application. When generating the initialisation code with MX, in the Core inc directory, MX generate a nema_hal.c fileIt contain only a file header. So, this is not a big problem but it is annoying. I tried to find what component was generating this file with no success.What can I do to avoid this file to be generated?My configuration:STM32CubeMX version 6.7.1F4 Firmware version 1.27.1TouchGFX version 4.21.0I tried to find out with the log of the MX, STM32CubeMX.log what component was creating the file. But there is not enough information. How to change the log level generated by MX?Thank you.

Hi!! To test how the SWV data trace timeline graph works, I have a simple application where I increment by 1 a variable called count. Very basic. In debug mode, I see count increasing correctly in the live expressions window. while(1){ count++; HAL_Delay(250); }This is not the case for the SWV window where the variable value are completely wrong.Where can the problem be? Thank you!

Hello,I'd like to get access to P2RAM to generate some sort of "Unique ID" between multiple ST25R3916 communicating with a single stm32 host Mcu.How to get Access & Read this memory ? i saw it was mentioned in the Datasheet but not elsewhere. Thank you,

Hello.I want to drive a BLDC motor with Steval ptool1v1 hardware.I loaded the example file (6S_Steval_ptool_1v1_HS_WM) into the MCSDK-WB, from which I generated the code (via cubeMX and CubeIDE).The motor doesn’t work despite all my attempts. Even though potentiometer speed control is included in the user manual as plug'n play(!), I see in the cube IDE it is not implemented. Moreover, I did not find an option in the MCSDK Workbench where this could be selected.I tried to figure out in the code how to implement it afterwards, but I couldn't figure out the solution.How could this be solved?Thanks in advance.Bela.

I tried disable ROP level 1 to level 0 by ST-LINK Utility and STM32CubeProgrammer, but it is not success.Thanks in advance.

In ethernet HAL driver stm32h7xx_hal_eth.c function void ETH_DMARxDescListInit include row: " WRITE_REG(heth->Instance->DMACRDTPR, ((uint32_t)(heth->Init.RxDesc + (((uint32_t)(ETH_RX_DESC_CNT - 1))*sizeof(ETH_DMADescTypeDef)))));"This code adding value to heth->Init.RxDesc. But, RxDesc is pointer to 32bit and added shift is multiplicated for 4.Correct row must be:" WRITE_REG(heth->Instance->DMACRDTPR, ((uint32_t)(heth->Init.RxDesc) + ((uint32_t)(ETH_RX_DESC_CNT - 1))*sizeof(ETH_DMADescTypeDef)));"

The enable boxed are there, but only for EXTI line 2, it's greyed out.

I updated to TouchGFX 4.19.0 -> 4.20.0 and get this linker error. I cannot figure out how to fix it.

I wish to know the external memory address(0x60000000 - 0x7fffffff) partitions. And I wish to learn more about memory mapping. So, if there anyone find the detailed document about memory mapping, please share it with me.

I want to read and write data from Flash via spi. I try some tutorial, He tell me to config and use some library.I do it but it don't work. MCU:STM32L496ZGT6Flash: S25FL128LAGMFB010

I tried both "Run Target" from TouchGFX Designer, and Cube IDE (Cube MX) compile / debug result is black screen. Compile, debug and run is without errors.

Dear, I have a STM32F446 connect trough QSPI the S25FL064L .I ask if there is the possibility using STLINK and STM32CubeProgrammer to program the S25FL064L .Tell me if there are other solutions to program the external memory trought the STM32F446 by a external programmer .Thanks 

My code initialises the RTC using the standard CubeMX code but before setting the clock it tests for a valid year > 2018. This works perfectly and the time and date are preserved through resets of the uP. However, it appear that either the reset or the call to HAL_RTC_Init zeroes the fractions of a second stored in the RTC registers. This can be proven by repeated resetting the processor each time withing a second which causes time to stand still.Is there a solution to this so that the fractions of a second are preserved through resets and power cycles?Thanksstatic void MX_RTC_Init(void) {   /* USER CODE BEGIN RTC_Init 0 */ int up=RTC_SMOOTHCALIB_PLUSPULSES_RESET; int calibrate= -Option.RTC_Calibrate; /* USER CODE END RTC_Init 0 */   RTC_TimeTypeDef sTime; RTC_DateTypeDef sDate;   /* USER CODE BEGIN RTC_Init 1 */   /* USER CODE END RTC_Init 1 */ /** Initialize RTC Only */ hrtc.Instance = RTC; hrtc.Init.HourFormat = RTC_HOURFORMAT_24; hrtc.Init.Async

Hello, I have a stm32wb55 nucleo board,I want to know that whats is the logic behind that , In reference manual it says After a system reset, the MSI oscillator, at 4 MHz, is selected .Lets say I want to use HSI or HSE for specific application and I want to set SYSCLK, HCLKs and other clocks .How can I implement a code that configure HSI,HSE selection and SYSCLK etc. I want to do that using LL(low layer libraries). Thanks for your helps

The same question is applicable for other memory variants as well which belongs to the same family.

The Question (since this is a little long): Is there any known interaction between the WWDG timer and the bootloader located in System Memory? Is there any known differences in the F405 revisions that could have an interaction between the WWDG and bootloader?Hello, I'm working on a product that receives updates via the DFU bootloader. I have two batches of the same board received from the same manufacturer, and one batch is behaving strangely as I attempt to use this method to jump to the bootloader.The code is based off of this tutorial, and works flawlessly on older batches of the board. However, on a new batch, instead of jumping to system memory for DFU upload, the board will simply reset from the WWDG IRQ. The overall program feeds the WWDG every couple milliseconds, but by the time the program calls the SysMemBootJump() function, it should have disabled the RCC timers and the WWDG interrupt. In order to demonstrate the issue, I'll attach a sample project I made in CubeIDE that pr

Hi everyone! I m trying to compile my project but there is a problem. I use IAR as compiler and STM8S103XX. Why is that?

Hello,I am using BLE_OTA project for STM32WB55. I upload a bin file which is 350 kb using ST BLE Sensor. However, the upload speed is so lower for some phones. For example, it takes up to 450 seconds on some android phones while the others take 25 seconds. Is there any way to speed up?Thank you.Have a nice day.Serhat.

To test the Examples provided by TouchGFX Designer v4.20.0,I purchased the STM32F469I Discovery Kit.However, the TouchGFX Designer's Canvas screen is not loaded on the LCD screen.Downloading is perfectly completed. (Already I installed STM32CubeProgrammer v2.11.0 and I have experience in developing using STM32G071_NUCLEO board and X-NUCLEO-GFX01M1.)It seems to be related to UM1932 Chapter 6.2 32F469DISCOVERY prodct history.The board I have is (blue color pcb) DK32F469I@AU1 and MB1189-F469NIH6-B08But It seems that only (green color pcb) MB1189-F469NIH6-B07 is supported by TouchGFX Designer.Revision B-07 products are currently not purchasable.I'm in big trouble because It seems to be not supported by TouchGFX Designer.How can I test TouchGFX in DK32F469@AU1 Rev-B08 blue pcb board?Please help me....................................................................................................................................................For ST Empoyee1.
