Hi, I want to implement Free RTOS on SWTM32U575. When I am trying to configure it in the middleware but there is no options to enable Free RTOS. Is there a way to way to enable it ?

A write of size 294KB to STM32H7A3VGHx Internal Flash works, but a write of size 775KB does NOTBTW, same issue with STM32CubeProgrammer v2.16.0 

Processor: STM32H753I am attempting to continuously read an ADC, and transfer the data into a circular data buffer with the ADC. I configured everything in CubeMX. No matter what I try, I get a transfer error from the DMA the first time it reads. I tried  both DMA1 and DMA2 with different streams thinking maybe there is a limitation on which stream I can use to read ADC2. I extracted the configuration code for testing and example purposes, which gets run at startup.Init(): // void MX_ADC2_Init(void) hadc2.Instance = ADC2; hadc2.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV256; // ADC clock = 62.5 MHz / 256 = 244 kHz hadc2.Init.Resolution = ADC_RESOLUTION_12B; hadc2.Init.ScanConvMode = ADC_SCAN_DISABLE; hadc2.Init.EOCSelection = ADC_EOC_SINGLE_CONV; hadc2.Init.LowPowerAutoWait = DISABLE; hadc2.Init.ContinuousConvMode = ENABLE; // Enable continuous conversion mode hadc2.Init.NbrOfConversion = 1; hadc2.Init.DiscontinuousConvMode = DISABLE; hadc2.Init.ExternalTrigConv = ADC_SOFT

Hello,I get this compilation warning: The float formatting support is not enabled, check your MCU Settings from "Project Properties > C/C++ Build > Settings > Tool Settings", or add manually "-u _printf_float" in linker flags.The stated "recipe" to fix the issue does not work because there is no "linker flags" edit box in the mentionned dialog.Hence, what is the way to add linker flags in the IDE version I'm using, 1.15.1 ?Many thanks!  

Hi, I am using a STM32WB15 board for BLE applications. I understand I need to download the correct FUS before I can ask the board for running any programme. However, I find when using UART to connect the board I cannot running the FUS as well as wireless stack after they are downloaded. I tried set boot0 from 1 to 0 it seems not work. Do anyone know how could I make sure the FUS running when UART connection is used (unfortunately my board is not reserve other links e.g. J-Tag or SWD).

Heyho,any PTP specialists around here?I'm currently working with a new board using the H733 with a KSZ8863RLL ethernet PHY, and I have a strange PTP synchronization problem:If a board with a KSZ8863 is the PTP master, no slave can synchronize.The slave's filtered "offset from master" is always increasing, whereas when sync is working this value is getting closer to 0.As soon as the master is one of my other boards using a LAN8742 PHY (H735, H723, F767), all boards sync perfectly.I have checked and compared the PTP messages from the master in Wireshark, and I can see no difference between the masters' messages.The thing is that this is hard to debug on that level, as we're talking about timings < 100µs.I have checked all clocks, settings, played with the filters and the servo, no chance.What could be the difference between the PHYs which affects the PTP master output?Thanks in advance.

Hi, I have a NUCLEO-H7S3L8 and I think there is an addresses mistake in the .svd files and potentially other hardware description files.You can reproduce and see the mistake if you setup the SAI1_A and SAI1_B on CubeMX, generate the code and debug the program, you will see in the SFR widget of STM32CubeIDE (the .svd file) that it's the SAI2 registers configured instead.It also affects the CubeMX configuration of SAI, we can't set SAI1_A on Master and SAI1_B on Slave synchronous which is very annoying (image below). I'm not sure if it's the right place to report this, but I would really appreciate if you follow this issue on the right ST team.Thanks.

Hi, I am working on STM32F1 family and implementing LIN communication. I found the function HAL_UARTEx_ReceiveToIdle_DMA() that is very useful to handle variable incoming data. But I have a problem that this function only works first time, but not calling HAL_UARTEx_RxEventCallback(), I need to get data in USART1_IRQHandler() function. The reason is because the flag of Frame Error is arrising and stops the receive DMA process. The intersting is that the received data is correct, for all different RX size. I review all init and functions according to the examples and forum, and it seems ok.  Could it be because the link break detection? My RX buffer always show zero as the first byte, so it compute the break as first data.byte[0] = break;byte[1] = sync;byte[2] = PID... DMA init static void MX_DMA_Init(void) { /* DMA controller clock enable */ __HAL_RCC_DMA1_CLK_ENABLE(); /* DMA interrupt init */ /* DMA1_Channel5_IRQn interrupt configura

I'm simply trying to do:res = f_open(&fil, "file.txt", FA_CREATE_ALWAYS | FA_WRITE);but nothing is created despite the return message. Could it be my SD card? I'm able to read from it in 4B mode.Any suggestions would be gratefully received.

Hi, for my STM32CubeIDE projects it would be convenient to have a macro whose value increases every time I compile the project; As if it were a counter of the times I pressed the build button, to be used as an ID to identify the specific build.For example, in my code I would like to put a printf at the beginning that prints this number to understand which build the executable being executed belongs to.On other IDEs there is a way to make a kind of pre-build script that is executed before compiling the project, the question is: is it possible to write a pre-build script also in STM32CubeIDE? If yes, how? In what programming language? Can I read and write C-MACROs from these scripts?Thanks in advance

I'm using SPC58 DISP Board for RTR request data frame from a battery pack. I have set the RTR value as 1, but didn't receive any reponse data frame from the battery. I have tested with CAN analyser, reponse data frame is coming(working fine). When I looked into the code, I didn't see any RTR register loading with the value. So, if anyone worked on RTR frame request. Kindly guide me.Transmit data frame with RTR as 1. 

I have successfully got data going to Azure IoT hub, but now need to connect it to Azure IoT Central instead. I've not managed to get it to connect successfully though... This is the device settings, which are in the azure_iot config.h file, but I've been messing with it for a couple of days and can't tell if the problem is with some IoTCentral setting, or something in the firmware config... Anyone else had success with this board?  Most of the examples are for the other U5 board which I don't have.

Are there any STM32F413ZH breakout boards?

Hello,I had a use case to add dynamic bitmaps in a project I joined, and I followed the documentation to make them work.https://support.touchgfx.com/docs/development/ui-development/touchgfx-engine-features/dynamic-bitmaps Surprisingly, I realized that the addresses of dynamic bitmaps are not as I would expect them. The code I added that called Bitmap::setCache seems to be ignored.I dug into project internals and found that there is a call to registerBitmapDatabase during initialization, with cache parameter supplied, but there is not a lot about that function in the docs. Does this explain why my `setCache` was ignored?

Can variable values be stored in some fixed addresses of internal flash and retrieved from them after reset? is there any example for same.

Good morning everyone,I am trying to modify a bootloader that is already in production and working.My problem is that if I call the JumpToApplication() function right after peripheral initialization (as the production bootloader does), everything works perfectly.However, if I call it from within the infinite loop or even after exiting the loop, as you can see from the attached code, the jump does not work.I can't explain why.Additionally, I wanted to ask two more things:Is it necessary to define the array volatile uint32_t stack_arr[30]? I have never seen it in any bootloader.In the statement pmain_app = (void (*)(void)) * (APPLICATION_START_ADDRESS + 1); I see that there is a +1 at the end, but in various examples, I always see +4. Yet it still works!!!Can you give me some advice?Thank you.    #include "main.h" #include "dma.h" #include "fatfs.h" #include "spi.h" #include "usb_host.h" #include "gpio.h" #include "crc.h" extern HCD_HandleTypeDef hhcd_USB_OTG_FS; ext

We got the STM32MP157F-EV1 and struggle a bit with the understanding of OTPs. We cloned the STM32PRGFW-UTIL repository [1], put the dip switches into "forced USB boot for flashing" mode (all off) and uploaded the provided image: STM32PRGFW-UTIL\Projects\STM32MP15xx\Binary> stm32_programmer_cli -c port=usb1 -w .\FlashLayout_STM32PRGFW_UTIL.tsv That works great and we can query a register like this: stm32_programmer_cli -c port=usb1 -otp displ word=93 We then tried writing to it: > stm32_programmer_cli -c port=usb1 -otp write word=93 value=0xF0 and querying again shows the correct value: | Data93 : 0x000000F0 | Status93 : 0x00000000 We tried writing a second time with a similar value > stm32_programmer_cli -c port=usb1 -otp write word=93 value=0xF1 and the value changed as expected: | Data93 : 0x000000F1 | Status93 : 0x00000000 Then we wrote 0xF0, 0xF1 and 0x01 again just to see what happens. The Register still rea

Hello,I want to read which stack is updated in my controller. For example stm32wb5x_BLE_Stack_full_extended_fw / stm32wb5x_BLE_Stack_light_fw / stm32wb5x_BLE_Zigbee_RFD_static_fw. So can I read back the stack name using code? Is there any way to read the stack name? For reading the Stack version I am using this "SHCI_GetWirelessFwInfo" function. is there any function available to read the stack name? Thanks and Regards Sarthak Malik

Hello,I am trying to use the I3C interface between STM32H563ZI in MB1404 board and NXP's temperature sensor P3T1085UK. I have found a question would like to be answered: Is there any way to send the IBI header (7'h7E) with SCL signal configured in I2C timing characteristics?According to MIPI I3C Basic specification v1.1.1, page 33, table 3, note 3, It is expecting an I3C / I2C capable target having a switchable 50ns spick filter and the swtich is triggered by the IBI header (7'h7E).I have selected the "Bus Characteristics" as "Mixed I3C and I2C" and "I2C Duty Cycle" to be 50% in stm32cubeIDE's "Pinout & Configuration -> Connectivity -> I3C1", It generates the code with "hi3c1.Init.CtrlBusCharacteristic.SCLI2CHighDuration = 0x7c;", which seens fine. But when I run the function "HAL_I3C_Ctrl_DynAddrAssign", I found the waveform is different, the SCL high duration is actually controlled by the parameter "SCLI3CHighDuration", shown below.the SCL pulse is around 50ns and

Hi,I am new to STM32 MCUs and working on a small project at the moment. I following the reference manual but facing an issue that as soon as I enable ADC in CR, the MCU stops responding.

The EMC cutoff frequency of ST25R3911B is defined as 11.75MHz with L= 270 nH, C= 680p. However, the antenna resonates at 13.56MHz. I can understand if the cutoff frequency is defined between 14 -18 MHz to suppress the 2rd harmonic mode. Could you give some idea why you select the 11.75MHz, how the 13.56MHz signal transfer the filter?

Hi,I am new to the STM32 world and currently working on the following application on a STM32F103CBT6 @72MHz:1. Collect data from I2C sensor triggered from external interrupt @800Hz2. Read commands (MODBUS RTU) from USART and respond.I set up the uC with STM32CubeMX.ISR for Task 1 is simply:  HAL_I2C_Mem_Read_IT (adxl343_i2c_handle, adxl343_i2c_addr<<1,ADXL343_ACCEL_ZOUT_REG,1, d, 2); I do not even bother doing anything with the data in uint8_t d[2].ISR for Task 2, HAL_UART_RxCpltCallback() is: modb_rx_buff_head = (modb_rx_buff_head+1)%MODB_RX_BUFF_SIZE; HAL_UART_Receive_IT(&huart2, &(modb_rx_buff[modb_rx_buff_head]), 1); ISR for Task 2, HAL_UART_TxCpltCallback() is: // Clear the TX_EN pin on the RS485 interface IC HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, GPIO_PIN_RESET); There are no common variables between both tasks.Task 1 alone works perfectly (checked w/ oscrilloscope).Task 2 alone works perfectly .Task1 + Task2 : uC hangs (either immed
