Dear friends,FreeRTOS are supporting SMP functionalities that enables to run FreeRTOS Kernel in only one core and schedule tasks on multiple cores.https://www.freertos.org/symmetric-multiprocessing-introduction.html I am trying to use it, but it looks like the SPC5 FreeRTOS Component does not have the FreeRTOS SMP API.Please, someone already used the FreeRTOS SMP functionality?How to update the SPC5 FreeRTOS Component to the latest FreeRTOS release?Best regards.

Hello,I would like to know if is it possible to load an array data (from a text file or something like that) while debugging.Imagine to have the array int data[100];I would like to be able to fill it (while debugging) with values generated by me.Is there a way to do that? Thanks in advance  

All STM32 CortexM7 and M33 have a ADI V2 debug unit. ADI V2 requires Multi-drop support, so that several SWD devices can be connected to SWD in parallel. Only with an activation sequence including the target-ID of that device to use selects the device for debuging. Do Stlink debuggers support multi-drop?

Hi, We want to use now the STM32H5 for future projects. In the past, we used STM32F4 with enabled SWO for debugging. Is there any example available to get this feature working for STM32H503? Would be great to do it on register level to be independent from IDE...I've already read this thread: Solved: Re: STM32H7 SWO printf not working - Page 3 - STMicroelectronics CommunityBut I'm not sure about the differences between H5 and H7 Thanks for your help,André

Hello,Just wondering if anyone knows the reason for the duplicate writes to the following registers in the HAL Ethernet code please?ETH->MACCRETH->MACFCRETH->DMAOMRETH->DMABMRIn the example shown below (from HAL code) the DMA0MR register is written to, then read back, 1 msec delay and then written to.I've taken note of the need for the 4 clock cycle delay, however is it necessary to perform the duplicate writes?Thanks in advance.Edit: I'm using Cube FW F4 v1.28.   /*----------------------- ETHERNET DMAOMR Configuration --------------------*/ /* Get the ETHERNET DMAOMR value */ tmpreg1 = (heth->Instance)->DMAOMR; /* Clear xx bits */ tmpreg1 &= ETH_DMAOMR_CLEAR_MASK; tmpreg1 |= (uint32_t)(((uint32_t)((dmaconf->DropTCPIPChecksumErrorFrame == DISABLE) ? 1U : 0U) << 26U) | ((uint32_t)dmaconf->ReceiveStoreForward << 25U) | ((uint32_t)((dmaconf->FlushRxPacket == DISABLE) ? 1U : 0U) << 20U) | ((uint32_t)dmaconf->Transm

Hi,I had previously set up a USB serial  communication that has been working with multiple STM32 types and in multiple projects. With the latest update to STM32CubeIDE Version: 1.15.0 Build: 20695_20240315_1429 (UTC) I had a problem.Problem: unassigned variable warnings in USB_DEVICE/App/usbd_desc.c when tried to build the project. The project runs but the COM port number changes with each restart of the MCU which is very inconvenient for practical use. Workaround: In the file USB_DEVICE/App/usbd_desc.c edit the routine starting to replace the missing commands as per below.I hope this helps. Maybe it could be fixed in a new release.H. /*** @brief Create the serial number string descriptor* @param None* @retval None*/static void Get_SerialNum(void){uint32_t deviceserial0;uint32_t deviceserial1;uint32_t deviceserial2; deviceserial0 = *(uint32_t *) DEVICE_ID1; // Missingdeviceserial1 = *(uint32_t *) DEVICE_ID2; // Missingdeviceserial2 = *(uint32_t *) DEVICE_ID3; // Missing

Hi,I want to use random number.But, the same random number is generated each time it is run.When I debug the code below, W change with the same pattern every time I debug. What's the problem and is there any solution to make random number which is not depend on the order?   /* USER CODE BEGIN 0 */double uniform_rand(){return (double)rand()/((double)RAND_MAX + 1);}/* USER CODE END 0 */  int main(void) {/* USER CODE BEGIN 2 */srand(time(NULL));/* USER CODE END 2 */ while {W = uniform_rand();}}

I think I've spot a small bug into the cube mx code generation tool for STM_WPAN moduleinto app_debug.c in function  void DbgOutputTraces( uint8_t *p_data, uint16_t size, void (*cb)(void) ) { /* USER CODE END DbgOutputTraces */ HW_UART_Transmit_DMA(CFG_DEBUG_TRACE_UART, p_data, size, cb); /* USER CODE END DbgOutputTraces */ return; }  There is 2 "END" tags the first one should be a BEGINdue to this everything you wrote between both tag that should be kept when generating code from IOC file is scrapedthank's for the help   

Where can I find the DSP library for the STMF7 processors? In the CMSIS DSP Software Library documentation I read that I can use the arm_cortexM7lfsp_math.lib (Little endian and Single Precision Floating Point Unit on Cortex-M7). On the website of ST (https://www.st.com/en/embedded-software/stm32-standard-peripheral-libraries.html?querycriteria=productId=LN1939) it only goes up to F4.

Hi :)Problem: STM32F030R8T6 device not found.ErrorMsg in CubeProgrammer: "No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication."ErrorMsg in CubeIde: "Error in initializing ST-LINK device. Reason: No device found on target."Setup: I made a breakout-board for an STM32F030R8T6. The board only carries the µC and spreads out the pins to use on a breadboard. I connected all VSS and VDD pins and used 0.1µF capacitors as close as possible to the µC. I connected the ST-Link-V2 as follows:VSS -> any GND pinVDD -> any 3V3 pinNRST -> NRST  (pin 7) (not sure if I need to connect the pin somehow aside from the debugger)SWDIO -> SWDIO (pin 46) 220Ohm PullupSWCLK -> SWCLK (pin 49) 220Ohm PulldownI tried BOOT0 pin pulled low or high, both didn't work.I double and tripple checked my connections. I am using the right pins on both sides and the µC has power.  -------------------------------------------------

My updates schematic in this pin number 11 is now connected to gnd not to VDD This My schematic for your reference This is the error in cube MX. previously I had similar issue that time it was because of power supply.I don't know what the mistake in this design please help me solve this.I tried using both stlink v2 & segger jlink for programming.Kindly help in verifying power supply area in my design.

We are testing the app on a newer mobile and encountered this issue:Calling this function will cause the application to crash:mFtmCommands = new FtmCommands(mST25DVTag);The problem is in this procedure:private void setMaxTransmissionSize() { if (this.mST25DVTag != null) { this.mMaxTransceiveSize = this.mST25DVTag.getReaderInterface().getMaxTransmitLengthInBytes(); if (this.mUseAddressedMode) { this.mMaxTransmissionSize = Math.min(this.mMaxTransceiveSize - 12, 256); } else { this.mMaxTransmissionSize = Math.min(this.mMaxTransceiveSize - 4, 256); } }}specifically this line:this.mMaxTransceiveSize = this.mST25DVTag.getReaderInterface().getMaxTransmitLengthInBytes();If the mobile phone is close to the NFC antenna, the problem does not occur, if the phone is out of range, the application crashes.(There is not problem on the older Android Version 9...)

I've got an black pill with STM32F411CEU6 on it, I plan to simply use it for a single purpose: reading ADC at near full capacity and transfer values to PC via USB. After investigating around F411 product page on st.com, I've found that:ADCin product definition it is stated:1×12-bit, 2.4 MSPS A/D converter: up to 16 channelsSo, without transfer protocol overhead, i needs minimum of 2.4*12=28.8 Mb/s equal to 3.6 MB/s bandwidth to transfer data into PC.USBin product definition also it is stated:Advanced connectivity: USB 2.0 full-speed device/host/OTG controller with on-chip PHYfrom the definition of USB2FS (full speed), i can understand the maximum speed is 12Mb/s (equal to 1.5 MB/s). Main QuestionSo data rate from ADC is about 29Mb/s but maximum data rate from USBFS is 12Mb/s.Is there any method which i can send full ADC data from my black pill to PC, and preferably without external components (like discovery boards)?Thanksfoot note:It STM32F411 product page, USB2FS (12Mb/s) i

Hi,I need to configure DMA for the Rx path of my USART data. I was able to get the Tx path going correctly following this thread: https://community.st.com/t5/stm32cubeide-mcus/problem-adding-usart3-functionality-to-lwip-http-server-netconn/m-p/668703#M26841Now for the Rx path, the DMA gets setup in HAL_UART_MspInit() & this was copied as generated by CubeMX, i.e. and it's working on the other project (with CubeMX enabled) fine:else if(huart->Instance==USART3){/* Peripheral clock enable */__HAL_RCC_USART3_CLK_ENABLE();__HAL_RCC_GPIOD_CLK_ENABLE();/**USART3 GPIO ConfigurationPD8 ------> USART3_TXPD9 ------> USART3_RX*/GPIO_InitStruct.Pin = XZaber_TX_Pin|XZaber_RX_Pin;GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;GPIO_InitStruct.Pull = GPIO_NOPULL;GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;GPIO_InitStruct.Alternate = GPIO_AF7_USART3;HAL_GPIO_Init(GPIOD, &GPIO_InitStruct);/* USART3 DMA Init *//* USART3_RX Init */hdma_usart3_rx.Instance = DMA1_Stream1;hdma_usart3_rx.In

Hey all, I'm attempting to implement the EEPROM emulation library into a pre-existing project with little success. I've added the eeprom.c file to the project as well as the header include to the main.c but even prior to implementing the code, attempting to compile/build throws an error that the "FLASH_Status" identifier is undefined. This variable is found inside the stm32f10x_flash header. I've added it from the StdPeriph file into the project but the compiler can't seem to locate it.  This process if fairly new to be so I presume I'm missing some simple step to implement the library, any assistance would be appreciated.  processor is an STM32F103programming in IAR Embedded Workbench

Hey all,I've been losing my mind over this error message that generates right on the while(1) line. it says "undefined reference to `SX1276' ", but SX1276 is defined in the PV section.

Hello all,   I am using the CAN protocol to read and write data from the Flash memory of one STM32F446ZET6 board to the Flash memory of another STM32F446ZET6 board. I have tried multiple baud rates. All working properly. However, I notice a 25 ms delay between every CAN frame, regardless of the baud rate.  Is this a default setting and/or is there a way to change this time delay?   Thanks! 

Hello world. This is my first post to the forum so please be tolerant if I inadvertently breach local etiquette. I have some experience with RPi, Mbed and Arduino systems but none with the STM32F range until very recently when I was given a few kits to play with. Unfortunately absolutely no documentation was provided with any of them. The STM32F769I-EVAL will serve as an initial example, as that is the one with which I have been playing for a few hours. It powers up and displays lights, some of which flash under certain circumstances, and sometimes appears as a USB disk drive on the development computer. That drive contains precisely one file. A vast range of documentation is available and I have downloaded a selection, along with development software. I am using a Ubuntu 23.10 amd64 system; The IDE fires up correctly, as far as I can tell. However, no documentation yet found is at a sufficiently basic level to enable me to make use of the material I do have. Neither have I yet found a
