Affected driver libraries: STM32Cube_FW_L5_V1.4.0, STM32Cube_FW_L4_V1.16.0, STM32Cube_FW_L0_V1.11.2 and possibly other device driver libraries based on the same SPI peripheralFile: stm32yyxx_ll_spi.h (Replace yy by L5, L4, F0, ...)Functions affected: LL_SPI_ReceiveData8Bug: Current implementation performs a 16bit read access to DR register and then casts the result to 8 bits. This leads to unexpected behavior. For example STM32L5 supports data packing, when SPI data frame size is less than or equal to 8 bits and 16 bits are read. In this case, the current implementation of LL_SPI_ReceiveData8 reads two (packed) bytes from DR register and discards the second one when casting the read result to 8 bits.Correct implementation: Cast pointer to DR register to uint8_t before access.__STATIC_INLINE uint8_t LL_SPI_ReceiveData8(SPI_TypeDef *SPIx){  return *((__IO uint8_t *)&SPIx->DR)}

Hello,As it is written in the datasheet, the propagation delay (Tpwm/d(on)) is 125ns. Does it means that if my PWM has a duty cycle less than 125 ns, the output will stay low? Or it is just a delay before seen my output getting high?Regards,Hugo

Hi all,I'm working in a project (with STM32L476) in which i am building my own bootloader to perform secure boot and firmware upgrade.I have some doubt regarding this matter. is there any resources available for secure the HEX file (encrypt and decrypt). if yes could help me out to find them. is there any please can you help me to find. Since i am newbie to the bootloader and firmware security. your response will be massive for me

Hi,I am using lsm6dsl sensor. I am getting data on out registers. How to convert that raw data into angle

While trying to test out the USB-PD middleware, I generated a project for the STM32G071RB Nulceo dev board with Tracer EMB and GUI interface enabled. Generating the code works fine however, I'm getting a compile error that traces back to the FLASH_SIZE macro in stm32g071xx.hIf I turn off the GUI module, the error goes away.I was able to work around the problem by changing the FLASH_SIZE macro to just be the hard-coded size of the flash on my part, but this isn't a good solution.The weird thing is, once I got the project to compile and load, I was able to past the original macro expression into the debugger expression evaluator and it came back with the correct answer (0x20000), so it doesn't seem to be a simple syntax error.Here is the error:In file included from ../Drivers/CMSIS/Device/ST/STM32G0xx/Include/stm32g0xx.h:117, from ../Core/Inc/usbpd_gui_memmap.h:31, from ../Utilities/GUI_INTERFACE/bsp_gui.h:23, from ../Utilities/GUI_INTERFACE/bsp_gui.c:22: ../Drivers/CMSIS/Device/ST/ST

Hi St,I am using NUCLEO-STM32L452REP board.I am trying to write a DOUBLE WORD inside the internal flash.I am writting to address 0x807D000 which is 8byte alligned.The address i am trying to write, its contents are 0xFF.I am calling below function:HAL_Flash_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, 0x807D000, 0x01);I am getting an error 0xa0 which equals programming allignment error.Please help.

I recently purchased the NUCLEO-F303RE and X-NUCLEO-IHM16M1 development kit.With a 2804 Gimbal motor.So far all the tests have gone well for me.But my intention is to control a sensored BLDC motor.Do you know of any sensored BLDC motor that works well with this development kit?Thanks!

Hello,I am working on Flighing sensors VL53L3 and I would like to run them in interrupt mode. But my board (Nucleo-64 STM32F091RC) doesn't detect any flag in the falling edge trigger. I have already run this interrupt mode on another board and this worked well. I also tried to set the interruption pin on the user Button and that's work perfectly!Moreover, I checked with a logic analyzer if the sensor set down rightly the interruption wire and it is the case.I saw on different forums that it's could be a memory issue or a clock one but I have any ideas to debug my issue...I will attach my project folder (I am working with AC6 tools for STM32).Thanks for future help

Hi, I am unable to initialize MotionGC library, since the function MotionGC_Initialize(&val) does not stop execution (pretty much like an infinite loop). Checking on the User Manual (UM2181), it is stated as a note regarding this function that " the CRC module in STM32 microcontroller (in RCC peripheral clock enable register) has to be enabled before using the library".Is this the root of the problem and if so, which is the RCC peripheral clock enable register?

Hello, I'm having trouble about use of lwip on Stm32h743. I'm using udp raw. I'm transmitting packet with 1ms period, there is no problem in sending/receiving. After 20-30 min, program is going to hardfault with 'Imprecise data access violation'. It is occuring at mem_free(void *rmem) function in mem.c file. The stack was just like this: GATEWAY_ADDRESS() -> mem_free() -> HardFault. I'm also attaching the disassembly. Thank you for your helps.

Can someone explain to me why CubeMX creates handles for objects within main but the GPIO configuration for that object (example an A/D or USART using DMA) is configured under the stm32l4xx_hal_msp.c instead of right within main as part of the object?

Is the nucleo-wl55jc available in the market?And I wanna know what's the difference between the wl55jc1 and wl55jc2, which one of them should I buy for my region (North Africa)?

There is a array:uint8_t dat[8] = {0xcd, 0xcc, 0xcc, 0xcc, 0xcc, 0xdc, 0x5e, 0x40};It means a double variable data in memery. The value is 123.45. This code can be run in my computer: int main(int argc, char *argv[]){  uint8_t dat[] = {0xcd, 0xcc, 0xcc, 0xcc, 0xcc, 0xdc, 0x5e, 0x40};  double test = *((double*)dat);  printf("%.3f\r\n", test);  return 0;}It will put: 123.450But on stm32f103rct6. It will stuck when I run this: double test = *((double*)dat);But use float will not stuck: float test = *((float*)dat);So, how can I convert memery to double rightly on stm32f103? (I use stm32cubeide)Thanks!

I have custom NFC reader board with ST25R3916. The antenna has been geber copied from X-Nucleo-NFC06A1 board and the matching circuit is modified from X-Nucleo board. The varicap values have been merged with fixed capacitors. The MCU is STM32L476 and the FW is slightly modified from en.X-CUBE-NFC6. I have commented out (hopefully) all AAT and antenna tuning related lines on analogConfigTbl_NFC6A1.cWhen I measure the X-Nucleo board, TX signal is on about 70ms. On the custom board the on time is 1.2sWhat could cause the longer TX on time on the custom board?Best Regards,Stinde

Hello,As title said, I am working on SPC58EC-DISP. I have tested the example code SPC58xx_RLA_CAN Test Application for Discovery and it works for External Loopback mode. Now I want to transmit and receive CAN data with another physical CAN device using No_Loopback mode for CAN1, but I'm yet to succeed in seeing any data with external device. I have 2 external USB-CAN adapters that see each other data at matching baudrate. But none of them can see data from SPC58EC-DISP. Some of the things I have in my set-up:I have 120 ohm resistor in the CAN wires. I left the PIN setting from the example untouched which are using pin 119 (PIN_RX_1_0) and 118 (PIN_TX_1_0)I tried to connect my USB-CAN adapter to the DB9 CAN1 connector on the SPC58EC-DISP as well as the CAN_1_H & CAN_1_L pin TX Mode is DEDICATED, and TX Buffers is 32. I give the loop 100ms delay between TransmittingI can confirm that the CAN1 port send messages up to the 32 message buffer before it goes into CAN_MSG_WAIT state. My th

I am using STM32CubeIDE in Ubuntu20.04.If you create the STM32MP1 project in STM32CubeIDE for Ubuntu, it asks if you want to install the OpenSTLinux SDK. And I have installed it and am using it.However, in STM32CubeIDE for Windows, if you ask if you want to install the OpenSTLinux SDK, it indicates that the installation can only be installed on Linux, and installation is not possible.If you look at the attached picture, you can see the OpenSTLinux SDK Manager menu in STM32CubeIDE for Ubuntu, but there is no that menu in STM32CubeIDE for Windows.I want to develop STM32MP1 Firmware in STM32CubeIDE for Windows because it is inconvenient and slow to use the virtual machine, but I wonder if there is any problem even if I do not install the OpenSTLinux SDK and develop the firmware.

Dear STM community,I am trying to deploy a simple tflite model on my STM32, but I can't get through the analyze step. I got the following error:TOOL ERROR: Unknown layer type SHAPE, stopping.If I convert the model to Keras (model and topology), it works fine, I can run the generated code, but I want to use tflite model.I attached the keras and the tflite files.Thanks,Titusz

I have ordered P-Nucleo-IHM001 via Digikey.When trying the default FW, both FOC and 6-steps, the motor is not rotating.I connected the motor to a drill and rotate it, all three wires will produce around 1V peak to peak.Here is the video when testing.https://www.youtube.com/watch?v=3GXGae1relgAny idea which one is faulty? Motor, driver board, etc?
