Problem When i call * USBPD_PE_SVDM_RequestAttentionI get a OK message response but the callback never gets called.  * USBPD_VDM_SendAttention Curious to know if there's any good way to debug this?  Current debugging stepsI have a STM32G0-Disco board setup to capture the messages over USB-PD and display them with ST's USB-PD monitoring software.  So i know the attention pin is not currently activating.  I have a breakpoint to make sure that USBPD_PE_SVDM_RequestAttention is being called.  If i wait a few seconds and then trigger it to call USBPD_PE_SVDM_RequestAttention again i get a BUSY error.  So i figure it's trying to send it, it just can't?   My projectI'm using this as my base with a stm32G071- nucleo board.  I grab the CC lines from usb with a breakout board that passes the USB datalines through.  * https://github.com/STMicroelectronics/STM32CubeG0/tree/master/Projects/STM32

Initially a comment on the How to program an STM32 with another STM32 using an embedded bootloader Knowledge Base article.Moved to the forum for better visibility & discussion.STM32G071 --> STM32F072 Hello Mr Montanari,Thanks a lot for your article.I carried out the following test with Host: STM32G071KBT6 and devices: STM32G071KBT6 or STM32F072RBT6. In both cases, I encounter a problem when reading the Flash (0x4002200); the response is NACK (STM32G071) or ACK followed by NACK (STM32F072). Could you indicate potential solutions to resolve this problem? Thank you in advance.

Hello all,I'm facing a wired issue. After the IDE update in the Help menu there is no more the entry to log-in in myST.Do you have any suggestion how to reach the myST login from it?I'm running the IDE on Windows. Thanks in advance!

Dear community,I am currently working with the SPC58 E-Line processor placed in the mother daughter evaluation board.I am using the AEK-MCU-SPC5LNK with OpenOCD. The reference manual for the E-Line is similar o the G-Line. I have only found the SVD file for the G-Line, so I therefore thought, that using this SVD file could work. Sadly the peripherals remain blank and I cannot see any memories.I would be very happy if someone could tell me, how to get the correct SVD file or what do I have to change to get it running.Kind regards,Tassilo P.s I have used the attached manual, to access the peripherals: How to use the AEK-MCU-SPC5LNK programmer and debugger for SPC5 automotive microcontrollers - User manual

Hi, can anybody identify this MOSFET please? Google and ST search engine couldn't help me. Thank you in advance, István

Hello everyone, my programme on Nucleo-F767ZI do not run when I power ON by external power supply. I force to press reset button or power supply st-link by usb cable.I searched some solutions such as: BOOT0 to GND; or turn on bit POR = 1 in RCC_CSR, but nothing worked. I don't want to use external circuit to reset.Anyone can share with me some useful solutions to solve this issue?

Good day,I'm trying to get motor profiler running on an X-Nucleo-IHM17M1. The only compatible Nucleo board I have is a F303RE.To enable the motor profiler application, it requires the selection of 3 shunt current sensing. According to this link, it seems that both the IHM17M1 and F303RE support 3 shunt current sensing.Yet, when I try and configure the project, only single shunt is available. This is not the case for the other Nucleo boards.That said, I do receive the following warning when creating the project.Is there any solution for this, or should I use a different Nulceo board?

Hello!I have encountered a problem - I am unable to create a project for STM32F769I-DISCO board with both FreeRTOS using CMSIS_V2 interface and LwIP with NO_SYS parameter set to "OS Used".In old project that was setup with STM32CubeMX V6.14.0 using STM32Cube FW-F7 V1.17.2 I had no problem with setting both CMSIS_V2 and "OS Used" value.In new project that uses STM32CubeMX V6.16.1 and STM32Cube FW_F7 V1.14.4 I have to use CMSIS_V1 interface for FreeRTOS if I want to change LwIP's NO_SYS parameter to "OS Used".Did something change in recent updates, is it a bug or am I doing something wrong? Thank You for help in advance. Using FreeRTOS with CMSIS_V2Can't change NO_OS parameterCubeMX 6.16.1, Firmware F7_V1.17.4

Hi,Do we have sample code demonstrating continuous conversions for U545 ADC1 with GPDMA using "Standard Request Mode". The sample code should use two or more channels - say IN1, IN2. I am migrating a project from F105/F405 and am a little overwhelmed by the setting options to be configured with U545.The ADC_DMA_Transfer example at STM32Cube\Repository\STM32Cube_FW_U5_V1.8.0\Projects\NUCLEO-U575ZI-Q\Examples\ADC\ADC_DMA_Transfer  uses Linked-List Mode and only demonstrates a single ADC channel. Thanks.

Hello,I am unable to connect to TouchGFX version 4.26 to download or access the demo and example projects from the software download section.My system is connected to the internet; however, the application itself does not connect to the server.Please let me know how I can resolve this issue. 

Hello,I have a question about the flash memory map in the Secure project.I’m using the following application as an example:STM32Cube_FW_H5_V1.5.1\Projects\NUCLEO-H563ZI\Applications\ROT\OEMiROT_Appli_TrustZone\STM32CubeIDEIn the memory map, two flash regions are shown: - FLASH:              0x0c018400 - 0x0c01dfff - FLASH_NSC:    0x0c01c000 - 0x0c01c3ffQuestion:Should the FLASH_NSC region overlap the FLASH area, or should it be placed after the FLASH region?If it should overlap, what is the purpose of doing that? In this example, it overlaps.Thank You.

Hi,In paragraph 1.2 “Launch the provisioning script” I read that:Launch one of the provided scripts depending on your IDE:For EWARM or MDK-ARM: launch the provisioning.bat script.For STM32CubeIDE: launch the provisioning.sh script.I have Windows and STM32CubeIDE. Can I run the provisioning.sh script on Windows?Looking into the env.sh script, I found the following code:  echo ${OS} | grep -i -e windows -e mingw >/dev/null if [ $? == 0 ]; then echo "" echo " ==========================================" echo "| For Windows OS, please use .bat scripts. |" echo " ==========================================" echo "" echo " Press any key to continue..." echo read -p "" -n1 -s exit 0 fi  It seems that the script cannot be run on Windows.Could you please advise how to run the provisioning script for STM32CubeIDE on Windows?Thank you very much for your support.Best regards,Marco

Hello, I would like to know if I can use FP-AI-Vision to design my own application, for example, to detect trees in a yard. Or is it designed only for the three applications: food recognition, person presence detection, and people counting?

Good morning,I would like to measure the supply voltage on an STM32H573RI. To do this, I measure VREFINT and then want to calculate the supply voltage.My approach (simplified):sConfig.Channel = ADC_CHANNEL_VREFINT; sConfig.Rank = ADC_REGULAR_RANK_1; sConfig.SamplingTime = ADC_SAMPLETIME_640CYCLES_5; sConfig.SingleDiff = ADC_SINGLE_ENDED; sConfig.OffsetNumber = ADC_OFFSET_NONE; sConfig.Offset = 0; HAL_ADC_ConfigChannel(&hadc1, &sConfig); while (!__HAL_ADC_GET_FLAG(&hadc1, ADC_FLAG_EOC)); return HAL_ADC_GetValue(&hadc1); Using the ADC value of VREFINT, I calculate the supply voltage as follows:static uint16_t Calc_VREF(uint16_t adc_value) { uint16_t vrefint_cal = (uint16_t) (*(uint16_t *) (0x08FFF810)); uint16_t vrefint_voltage = 3300; return (uint16_t)(vrefint_voltage * vrefint_cal / adc_value); } My ADC delivers a value of 1.562 digits for VREFINT, while the calibration value is 1.503 digits. According to my calculations, the reference voltage is therefor

Hi community,I am working with STM32H747I-DISCO Board(Dual cortex M7+M4)MP34DT05-A digital MEMS microphone is integrated on the board and issues are facing while bringup.Issues follows:As per the schematic there is one digital microphone connected to the MCU using SAI Interface with default connectionsI am trying to bringup it with the help of refernce document(Ref AN5027).When i am understnading this document a few questions have been raised. Those question as follows.1.There are two types of mode  mono modestereo mode       stereo modeIf we see the schematic:One digital microphone is connected to stm32 MCU and it looks like mono mode configuration But when I am following mono mode configuration process to bring up it then pins which are enabling while configuring is mismatching with pins which are connected to this digital microphone as per the schematic.Connection pins – (SAI4_CK1) PE2, (SAI4_D1) PC1 (as per the schematic)Enabling Pins :In stereo mode config

I am using STM32WBA5MMG in my design. This the development board schematic. Below image is from development board schematic.As per the constrains , SWDIO and SWCLK must be length matched. Also need to provide a shield.My questions are given below.SWDIO and SWCLK are not differential lines, why length matching is required for them.By shield did they mean routing SWDIO and SWCLK on top of a solid GND plane

Hi everyone,I’m trying to get the LwIP examples from the stm32-hotspot GitHub (this one: https://github.com/stm32-hotspot/STM32H7-LwIP-Examples) running on my NUCLEO-H723ZG, but I’m hitting a wall.The README is actually great and super clear, which is why I’m surprised I can’t get it to work. I’ve built the project and flashed it to the board, and I have it connected directly to my laptop via Ethernet.The docs say the IP should be 192.168.1.10, but when I try to ping it, I get nothing. I also took a look at the code and it looked like the IP might be set to 192.168.1.1 instead, so I tried pinging that too, still no luck.Am I missing something basic here? Is it enough to just build and flash the code, or do I need to tweak some jumpers on the Nucleo or change my laptop's manual IP settings to be on the same subnet?I’d really appreciate it if someone who has used this repo could point me in the right direction.Thanks!mpek29

I have a simple function with loop that checks RX pin state for 10ms, and if there was high level - breaks loop and exits. it works ok with -O0, but is broken with -Os or -O1 (-O2) or -Og - it loops forever.Here's code:uint8_t isModemOn() { uint32_t expire = uwTick + 10; while (expire - uwTick < 11) { // check RXD pin level, if low for 10ms - consider modem is off if (LL_GPIO_ReadInputPort(GPIOA) & LL_GPIO_PIN_10) { return 1; } } return 0; }and how it's appears in listing080003dc <isModemOn>: * @PAram GPIOx GPIO Port * @retval Input data register value of port */ __STATIC_INLINE uint32_t LL_GPIO_ReadInputPort(GPIO_TypeDef *GPIOx) { return (uint32_t)(READ_REG(GPIOx->IDR)); 80003dc: 21a0 movs r1, #160 @ 0xa0 //#pragma GCC optimize ("O0") // Error in -Os optimization uint8_t isModemOn() { uint32_t expire = uwTick + 10; while (expire - uwTick < 11) { // check RXD pin level, if low for 10ms - consider modem is off if (LL_GPIO_ReadInputPort(GPIOA) & LL

Hi @TDK ,I have just downloaded and installed the new version 2.0.0 of the IDE and the MX software (since it is no longer integrated). I was working on a project based on the STM32WB5MMG, and everything was working correctly with IDE version 1.19.0 and STM32Cube FW_WB V1.23.0.After opening the project and regenerating the code with the new IDE version and STM32Cube FW_WB V1.24.0, I noticed some issues: in custom_stm.c it generates two times this variables:/* USER CODE BEGIN PM */ /* USER CODE END PM */ /* Private variables ---------------------------------------------------------*/ uint16_t SizeFw_Ver = 1; uint16_t SizeDatetime = 7; uint16_t SizeStatus = 6; uint16_t SizeMonitor = 15; uint16_t SizeEnv_Data = 90; uint16_t SizeFw_Ver = 1; uint16_t SizeDatetime = 7; uint16_t SizeStatus = 6; uint16_t SizeMonitor = 15; uint16_t SizeEnv_Data = 90;​2. it doesn't generate any local functions in custom_app.c:/* USER CODE END FD */ /***************************************************

Hello,I am trying to communicate with an SDI-12 sensor through my custom STM32L4 pcb. The communication that I am trying to achieve is from a 3.3V microcontroller. Thus, I used the SN74LVC1G240DBVT buffer to convert my UART to SDI-12 data one wire, and also I had a MOSFET which converts my 3.3V of the pin to 5V (I have checked that the hardware wiring and voltages working as expected). For my UART protocol, I have this configurations: static void MX_UART5_Init(void) { /* USER CODE BEGIN UART5_Init 0 */ /* USER CODE END UART5_Init 0 */ /* USER CODE BEGIN UART5_Init 1 */ /* USER CODE END UART5_Init 1 */ huart5.Instance = UART5; huart5.Init.BaudRate = 1200; huart5.Init.WordLength = UART_WORDLENGTH_8B; // Including parity huart5.Init.StopBits = UART_STOPBITS_1; huart5.Init.Parity = UART_PARITY_EVEN; huart5.Init.Mode = UART_MODE_TX_RX; huart5.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart5.Init.OverSampling = UART_OVERSAMPLING_16; huart5.Init.OneBitSampling = UART_ONE_BIT

 I have seen recommendation for by pass capacitor to be 10 times the boot strap capacitor for Mosfet driver IC's. When i verified the schematics of mb1419-g431cbu6-c01_schematic The Boostrap capacitance value is 1uF but the By pass capacitance value is 470nF between VCC and Gnd. Request to please clarify.      

There have been a few posts on this forum with the same issue, but it seems the root cause is different to this post or (probably) this one.I am using an Stm32f446re Nucleo, and trying to output a waveform from dac2 using dma and tim6.  What I have tried so far:   Trigger is set to Timer 6 Trigger Out event. DMA is configured in Circular Mode. I'm calling HAL_DAC_Start_DMA(...) Tried changing the data width to half word and word, neither worked. Callback functions are correctly named and defined in main.c: void HAL_DAC_ConvCpltCallbackCh2(DAC_HandleTypeDef *hdac) { HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_8); } void HAL_DAC_ConvHalfCpltCallbackCh2(DAC_HandleTypeDef *hdac) { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_8, 1); } I want to be able to set a flag variable to start processing the next buffer. I will paste the rest of my code, it includes a (buggy) sine wave table but I can fix that once the callbacks are handled properly. It is just something to sen

I'm working on a battery management system using an STM32F302 going to an AEK-COM-ISOSPI1 dev board using the L9963T transcevier which is daisy-chained to 10 AEK-POW-BMS63EN boards using the L9963E chip.The problem that I'm having is that when I send a message over the ISO SPI lines, it adds an additional 0 before it sends the message.I have attached two messages that show the leading 0 bit that is added. msg 0x55 55 55 55 55 and msg 0xFF 00 FF 00 FF. SPI settings are8 bits frame MSB first Baud rate 1000 kbits/secCPOL lowCPHA 2 edgeCRC Disabled How would I go about removing the leading zero from the message? Any help would be greatThanks
