Hello Devs,Currently i have 2 firmware performing same task with different target board selected i.e:Firmware 1: NFC DFU with STM32L496ZGFirmware 2: NFC DFU with STM32L4A6ZGFirmware 1:Currently in my project with target board selected as "STM32L496" and NFC Tag ST25DV04KC tag, i am performing NFC DFU using dual bank mode. Now everything works fine in this firmware, i am able to download the firmware in Banks and by setting/resetting BFB2 optional byte, i am able to swap banks as well. And also when i flash the same project on "STM32L4A6ZG" i am still able to perform Dual Bank update. Firmware 2:But when i create new STM32 project with target selected as "STM32L4A6ZG" and rest firmware is same like Firmware 1 still after storing the packets from the NFC in Bank 2 and after setting BFB2 optional byte my program stucks after execution of function "HAL_FLASH_OB_Launch". So can anyone please help me with this issue. Below is the ToggleBankandReset function which i call after successfully tr

hello,We have a product using STM32H750 chip. We used STM32CubeIDE(latest version: 1.13.2) to develop our software. We also integrate freeRTOS in our product code. We got a reboot issue sometimes on our product when we run  on STM32CubeIDE. It is strange that normally the code should stop in STM32CubeIDE when we got crash or exception etc, then we can see where the code crashed.But this issue is we just see STM32H750 keeping reboot, we see nothing on STM32CubeIDE. What will cause this kind of issue? How to debug this kind of issue?Thanks

I know this is probably a really stupid/noob question but I was trying to flash the STM32MP157D-DK1 board I have for the first time following the following guide:https://wiki.st.com/stm32mpu/wiki/STM32MP15_Discovery_kits_-_Starter_Package I ran into an issue where it started the flash and then couldn't reconnect.  I did find this article that seems to describe exactly the issue I'm having:https://community.st.com/t5/stm32-mpus/faq-stm32mp1-stm32cubeprogrammer-usb-reconnect-error-at-stm32mp1/ta-p/49263 It recommends: In Uboot shell run a Dfu command : STM32MP> env set dfu_alt_info "DDR ram 0xC0000000 0x20000000" STM32MP> dfu 0 ram 0  Unfortunately, I don't know how to run a uboot shell to try this.  I know this is probably a really stupid problem . . . but I'm also hoping that means it has an easy solution as well.  Any help you can give me would be greatly appreciated.  Thanks!

Hello,I plan to use VL53L5CX to measure the distance between the robot and the user (human) in the walker project. I would like to ask if it is safe or not. Regards,Fehmi.

When I try to add USB_OTG_FS (host only) to a project which uses FreeRTOS the code locks up on initialisation of USB_OTG_FS. When USB OTG FS is added, a call to "MX_USB_OTG_FS_HCD_Init" is added to "main" function. It goes before a call to "osKernelStart()". During initialisation HAL_Delay is called, and the code locks up on that.The path looks like this: MX_USB_OTG_FS_HCD_Init >> HAL_HCD_Init >> USB_SetCurrentMode >> HAL_Delay(1U)And that is where it locks up.If I comment out the call to "MX_USB_OTG_FS_HCD_Init" the rest works fine. If I put "HAL_Delay" in one of FreeRTOS threads, that works as expected (presumably due to OS being fully functional by that point). If I put "HAL_Delay" just before a call to "osKernelStart()" - it locks up.It seems that HAL_Delay cannot be called before the call to osKernelStart, and the auto-generated code for initialisation of USB is doing exactly that.Is it a bug or I am missing something? What would you recommend?

STM32H7 SeriesI am trying to use CoreMark performance measurement for STM32H747. This YouTube video "STM32F7 workshop: 02.10 Cortex M7 core - Hands-on #4, coremark" indicates a web link to download, but it is no longer available.Is there a way to download CoreMark performance code for STM32H7? 

Hello,We are looking at using a STM32F405 in our power design LLC/PFC where we would need 4 complementary signals. 2 for the LLC and 2 for the PFC.Looking at the reference manual I see the following:17.3.11 Complementary outputs and dead-time insertionThe advanced-control timers (TIM1 and TIM8) can output two complementary signals andmanage the switching-off and the switching-on instants of the outputs.So, it looks like for this part there is only the two complementary signals on TIM1 and TIM8?Thanks for any insight.Brent

I want to use the flux weakening in my project using Workbench 6.2 i generated the code using the below settingwhen i select the speed control mode i can see the tab to select the Flux Weakening regulator.But when i select the torque control mode The tab for the flux weakening regulator does not appear. I know the flux weakening regulator is used to increase speed. The code for flux weakening does not generate in Torque control mode. So can i use the flux weakening code in torque control mode or not? Can i use the negative Id to increase the speed limit. My idea is a. generate the code for flux weakening using the speed control mode.b. integrate the code.c. Use the torque control mode and give negative Id.Does it work like this? Please help. 

Using CubeMX I try to configure USART6 clock for STM32U5A9ZJT6-Q.It seems that CubeMX allows to set clock source for USART1-3, but not USART6.Am I missing something or it is a CubeMX bug.

Good morning, I am trying to read from adc two signals by first saving the signal with a certain clock frequency and then changing it using another one, i.e. changing the AHB clock divider. Going to debug it crashes on hard fault handler, regardless of the clock change but even trying to do two buffer reads and moving them to other variables it can't get into the second switch case. Any ideas? Thanks in advance   CODE while (1) { u++; switch(u) { case 1: //SystemClock_ConfigDOWN(); for(i=0;i<ADC_BUF_SIZE/2;i++) { buf1[i] = (uint16_t)(adcBuf[i]&0x0000FFFF); buf2[i] = (uint16_t)(adcBuf[i]>>16); }   break;   case 2: //SystemClock_ConfigUP();     for(i=0;i<ADC_BUF_SIZE/2;i++) { buf3[i] = (uint16_t)(adcBuf[i]&0x0000FFFF); buf4[i] = (uint16_t)(adcBuf[i]>>16); }     break;     default: __NOP();   }   return 0; }

Hi,Currently, I am working on a project where we need to transfer data from PC to uC (STM32L4 series) at a high rate (real-time application). So, we have decided to use USB 2.0. First, we tried the communication device class, but it wasn't fast enough. So, now we are trying using the audio device class (also because of synchronization). I am using STM32CubeMX to initialize the discovery kit with STM32L4R9AI as a USB device with audio device class. I have generated the code, made no changes to it, and simply flashed the code and connected the USB in the hope that it will be recognized as an audio device (I have shared the *code as a zip file). But in device manager, it is always shown as a virtual COM port. I can't understand if it is a driver problem on the PC side or if the error lies on the uC side. I have tried uninstalling the device in device manager and again plugging in. But nothing works. I am also finding difficulties in with the documentation(couldn't find proper documentatio

I try implementing FOC for Bull Running BLDC motor with F302R8 Nucleo board and IHM07MI expansion board.Help me in this regard. 

Hello all,does the vl53l5cx ULD API (STSW-IMG023) can expose  a unique device ID for the VL53L5CX ? Something similar to the VL51L1 API function call "VL53L1_Error VL53L1_GetUID(VL53L1_DEV Dev, uint64_t *pUid)"  in the driver SWSW-IMG019 ? Kind regards

I'm currently using the STM32 board B-U585I-IOT2A. The BLE module is working as BLE Server, and I want to transmit data.So, using BLE_NOTIF_VAL as explained here (https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WB_AT_Server), I can send 1 or 2 values maximum, and it's working, I can get back these values on the app ST BLE Toolbox.But, if I want to send 3 uint8_t values at the same time, it's not working anymore and any values are sent. And I would like to understand why and how to solve it. Because the buffer that the STM32 board can send to the Client is 64 uint8_t values. For exemple, I can send data through BLE_NOTIF_VAL1, and I receive x01x02. But, with BLE_NOTIF_VAL2, I receive x00x00.  Thank you for your help

I use STM32H745xi discovery board. When i do some test, i download code that Cortex-m7 will enter standby mode after power on 3 seconds. And i set wrong wakeup pin(wakeup pin 1&not config PA0, it should be wakeu4). After power off and power on, i find that it can't recognize the mcu through ST-LINK though i try RST pin. I dont understand why RST pin not work.Pls help to save the board,thx.  code: MX_GPIO_Init();HAL_Delay(3000);HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN1);while (1){HAL_PWR_EnterSTANDBYMode();HAL_GPIO_TogglePin(GPIOJ,4);HAL_Delay(500);}

Hello,I am using the STM32F107VCT6 microcontroller and, under normal circumstances, it works flawlessly. However, I have been encountering an issue where data in a specific memory area becomes corrupted when I toggle the nRESET pin at 2-3 second intervals. I would like some advice on how to resolve this problem or identify its root cause.Any guidance or suggestions on addressing this issue would be greatly appreciated. Thank you in advance.Best regards,

Hi，I am working with  STM32H5RBT6U：How do I calculate the frequency of the I3C Controller? Is there documentation to cover the content?I tried using CubeMX to set the frequency, but strangely, all the frequencies work fine except 3~5MHz. The exception is that at this rate setting, the controller can only send out the reserved byte waveform, and subsequent clock signals will not be generated normally
