SWV 16MHz, SYSCLK 16Mhz = logging worksSWV 16MHz, SYSCLK 25Mhz = logs gibberish (expected)SWV 25MHz, SYSCLK 25Mhz = logs nothing at allSWV 48MHz, SYSCLK 48Mhz = logs nothing at allWhy would this be?It works with HSI 16MHz, so my wiring and configuration must be correct. I'd expect gibberish from a mismatch, seems odd to see nothing at all.Maybe the V3PWR is at fault? I've ordered a V3SET and V3MINIE to compare.HSI isn't accurate enough for my needs. My HSE is 25MHz and PLLP output must be >= 24MHz, so I can't try HSE 16MHz.

I use the KIT STM32F411 DiscoveryWhen I choose:SPI CPOL: LowSPI CPHA: 1 EdgeIt works But when I choose:SPI CPOL: HighSPI CPHA: 2 EdgeIt does not work Could you explain why? Thank you! 

Hello Everybody,I'm designing a motor control board using the STM32F405 MCU in an LQFP64 package. When using STMC board designer, I noticed only a limited selection of MCUs is available (please refer to the attached picture ).  Could you advise how to import my specific STM32F405 configuration into the tool? My goal is to use MCSDK for generating runnable code for this custom hardware. Thank you!

Hi,Master：MCU: stm32h743iiIDE:keilQuestion：There is a 32M external SDRAM, and the scatter file is as follows:LR_IROM1 0x08000000 0x00200000 { ; load region size_region ER_IROM1 0x08000000 0x00200000 { ; load address = execution address *.o (RESET, +First) *(InRoot$$Sections) *(_drv_set_) .ANY (+RO) .ANY (+XO) } ... EXT_SDRAM 0xC0000000 0x2000000 { ; RW data *.o(ext_sdram) } }Suppose there are some variables in the program that are specified to be located in 'ext_sdram' section.static lv_color_t buff1[1024 * 600] __attribute__((used, section("ext_sdram"))); static lv_color_t buff2[1024 * 600] __attribute__((used, section("ext_sdram"))); ...During the scatter file loading, these variables will be initialized. Therefore, the external SDRAM needs to be initialized before the scatter file loading, as shown below:Reset_Handler PROC EXPORT Reset_Handler [WEAK] IMPORT SystemInit IMPORT __low_level_init IMPORT __main LDR R0, =SystemInit BLX R0 LDR R0, =__low_level_init B

Hi,MasterMCU:   STM32H743IIQuestion:Both FDCAN channels in the MCU are currently in use. I now intend to reset each FDCAN instance (i.e., reset all its registers) during its respective bus-off event, and then reinitialize the instance. Resetting all registers of an instance is typically done through the corresponding FDCAN RST bit in the RCC. However, since both instances share the same RCC, triggering the reset would affect both instances simultaneously. Therefore, I've made modifications for resetting a single instance as follows:HAL_FDCAN_DeInit(hfdcan); hfdcan->Instance->CREL = 0x32141218; hfdcan->Instance->ENDN = 0x87654321; hfdcan->Instance->DBTP = 0x00000A33; ...However, the aforementioned method can only reset some of the registers. Are there any better ways to achieve a reset of a single FDCAN instance? Thank you very much.

When using the NUCLEO-WBA55CG development board and running the BLE_HeartRateFreeRTOS example, I found that the delay time of osDelay is extremely long, nearly 10 times longer than the set delay time. What is the cause of this and are there any solutions?

Hello All, I am trying to use the SWV Statistical Profiler in STM32CubeIDE while debugging a stm32H7. I am also using ThreadX RTOS for the project.  I am getting debug output from the SWV Trace Log.  But nothing is appearing in the SWV Statistical Profiler.  The RED button is not grayed out - but it also does not log anything after pressing record when debug is paused. and then resuming.I have ITM Stimulous port 0 checked and PC Sampling and Timestamps checked, as well as EXETRC checked. I am wondering is this something that is disabled when using an RTOS?  I understand that the output will be spread between tasks. I am also running STMCubeIDE on linux. Any Help/Tips AppreciatedThanks,-Trevor

Hi All,   I want to build a system to sense 240 low current signals at 20kSPS at the same time using 15 ADC with 16 channels each (DDC316 by Texas Instruments, Datasheet: https://www.ti.com/lit/ds/symlink/ddc316.pdf). I intend to use something like the NUCLEO-H723ZG to drive this system. My question is: Is it possible to use OctoSPI to connect to 8 ADCs at the same time?As far as I can see from the datasheet the sorting of the data will be wrong since the interface expects a parallel data input but maybe I am missing a setting that allows for my use case. A secondary option would be using multiplexed QuadSPI. Something like this seems to be intended for the ADC, as it features a 4-datalane communication mode. However, again the data sorting (page 13 on ADC datasheet) is different from all the documentation I was able to find on QuadSPI (for example RM0468 or AN5050).   I would be very greatful for any input on this issue and appreciate any support. Best regardsMarco

hi,Question 1: Should I tune PolPulse directly at the end of profile? Without any pre-operation, such as changing "FOC Mode" from "profiling" to another one?Question 2: Which phases are the PWM waves and currents from? Are there any requirements when I probe the signals?Question 3: What kind of "Pulse current goal" is the best goal? (1/4 short circuit current as a starting point, What is ending point?)  How to tune the PolPulse step by step?Here is the Profiling Result as a reference.Above all,  thank you!

Hi everybody,On my project, my µC receives data from a rapsberry pi on a serial bus.For another project, I've used this method : https://github.com/MaJerle/stm32-usart-uart-dma-rx-tx/blob/main/projects/usart_rx_idle_line_irq_F4/Src/main.c to receive data with unknown length, it was working very well.So, i'd like to use the same thing, but I have something that I don't understand.For my test, Raspberry in sending the following frame every 10s ("DATA RASPBERRY"). My buffer has 64 bytes.The following line gives me the position of cursor : pos = ARRAY_LEN(buffer_rx_dma_rs1) - __HAL_DMA_GET_COUNTER(huart->hdmarx);So, the first time, it gives me 14, the second time 28 and the third time  32 (instead of 42), but 32 is the half of 64.When I take a look on the values, ARRAY_LEN(buffer_rx_dma_rs1) = 64 and __HAL_DMA_GET_COUNTER(huart->hdmarx) = 22, but pos = 32, how is it possible that the substract operation is false ?

I Tried to flash the uart code in stm32 N657 Nucleo Board, but it is not responding, i was able to make the Leds, blink in the N6 board. Please help me out, i am using the uart example printf code in the N6 stm32 package. I tried the normal method used in the STM32 F4 MCUs, also the selection of peripherals are different in the IOC file. also please explain how to configure the RCC and other peripherals in the IOC file of these N6 boards  

Hello everyone,I would like to update the STM32 remotely using ESP32. So the Idea is to transfer the signed image via Bluetooth and to store it firstly on the esp32, which will transfer it in the end via UART to the STM32.After that the secure boot on the stm32 must verify the image signature. I came across X-CUBE-SBSFU but I actually don't know how to use it in my case. Should I only use the Ymodem protocol ? Best regards

I write drive layer in MCU which is stm32f302r8t6. But I can't active to enable SPI clock register. Can you help me with that problem? Maybe you ask me that write in main.c as register level.   RCC->APB2ENR |= 0x0800; Actually I opened SFR and tried to enable SPI clock register but I can't.      

Hello, I’m working on a project with an STM32F446RE where I read data from a CAN bus at 500 kbps (CAN1_RX0) and also use I2C to control an MCP4725 DAC, plus timers and DMA for other tasks. The problem: When I test CAN alone, it works perfectly — I can receive all messages from my device (a motorcycle inverter). When I run the full code with all peripherals connected and active (CAN + I2C + TIM2 + DMA), the CAN stops receiving after a short time, or doesn’t receive at all. On the motorcycle, this happens consistently, but on the bench with CAN only, it works fine. What I tried so far: Set CAN NVIC priority higher than other interrupts:   Confirmed CAN1_RX0_IRQHandler() calls HAL_CAN_IRQHandler(&hcan1). Reduced I2C timeout to avoid blocking (HAL_I2C_Master_Transmit with 2 ms instead of HAL_MAX_DELAY). Tried opening the CAN filter (mask = 0) to receive all IDs for debugging. Enabled HAL_CAN_ErrorCallback  Despite all these changes, when all peripherals ar

I believe the STM32H743XGH6 has 1 MB of internal flash memory. However, using STM32CubeProgrammer, I was able to write and read data to the reserved area at 0x8180 0000. Is it okay to use this area?The built-in Flash Memory areas of the STM32H743XGH6 are recognized as0x8100 0000-0x817F FFFF and 0x8000 0000-0x0801 FFFF.

hello i am making a custom STM32F405RGT6 board for A DUAL_BLDC_FOC VESC project that am making. i looked up how to programme the chip and it seems i needed to generate the code using STM32cubeMX  after instaling the X-CUBE-MCSDK embeded software package then opening it on STM32cubeIDE.  but i could't find it even after downloading the latest STM32F405RGT6 MCU PACKAGE and refreshing it multiple times; then i downloaded the X-CUBE-MCSDK6 and it seems the custom stm32F405RGT6 is not suported on the workbench; when i tried to import the (.zip) file it showed an error window. is the F405RGT6 motor control software no longer supported by the new version of the stm32cube? if so what version should i download to find it?

Hi All,I am writing a code to generate an PWM at output. I want to drive an H-bridge outside.All initializations I have done.I am using TIM1 (advanced timer) for this purpose. I am using STM32F Discovery Board (Microcontroller is STM32F407) and STM32CubeIDE 1.19.0  The issue I am facing is whenever I get an interrupt i tried to load value from the LUT but its not working and generate unexpected PWM at output but when I load any fix value then PWM is generated at the output.I am wondering why it is not generating the PWM from LUT.below is my code. kindly tell me what I am doing wrong volatile uint16_t sineIndex = 0; #define SINE_TABLE_SIZE 10 uint16_t sineTable[SINE_TABLE_SIZE] = {400, 657, 794, 746, 537, 263, 54, 6, 143, 400}; int main(){ HAL_Init(); System_Clock_Source(); UART2_Init(); MX_GPIO_Init(); MX_TIM1_Init(); // Here all the settings are done related to PWM timings MX_TIM2_Init(); SPWM_Start(); } void MX_GPIO_Init(void) { GPIO_InitTypeDef GPIO_InitStr

Hi,I'm trying to import an ioc file for STM32MP257f-ev1. The original project was build on CubeMx 6.13 for MAC-OS using FW_MP2_V1.0.0 and I'm using CubeMx 6.13 under linux. When I open the .ioc file, It asked me if I want to migrate to FW_MP2_V1.1.0 or continue with the current version. If I choose to migrate everthing goes fine, but I continue with current package version CubeMX stack during the "Render UI" progress bar phase.Could someone help me?Marco.This is got the error log I got on terminal:Spoiler (Highlight to read)[FATAL] ProcessBarDialog:168 - ProcessBarDialog action 4java.util.concurrent.ExecutionException: java.lang.NullPointerException: Cannot invoke "String.equals(Object)" because the return value of "com.st.microxplorer.mcu.IP.getParameterValue(String, String)" is nullat java.util.concurrent.FutureTask.report(FutureTask.java:122) ~[?:?]at java.util.concurrent.FutureTask.get(FutureTask.java:191) ~[?:?]at javax.swing.SwingWorker.get(SwingWorker.java:612) ~[?:?]at com.st.m

Hello everybody, I would like to know when the VBUS voltage measurement is updated. I am using the functions to read the voltage:VBS_GetBusVoltage_dVBS_GetAvBusVoltage_VI am using the threads startMediumFrequencyTask, StartSafetyTask, and my own thread.At system startup, I want to load a buffer. But the measurements taken are incorrect or zero at the board startup.Is there any documentation on the acquisitions? MCSDK : 6.4.1Best regards.

Hi,Been a while :) Seeing some odd readings after the sensor has no real changes.  After some time when a change in the sensor distance happens it "seems" to take many readings to get good readings.Is there a sleep I don't know about? What is the recommended way to "wake up" the sensor if it has been dormant for some time......or am I imagining this? Thanks,Will
