Hello,   I may have found a bug related to the STM32C092GCU6 MCU and the FDCAN peripheral.   I created a new project and experienced issues with FDCAN reception: no RX messages were received, and the callback HAL_FDCAN_RxFifo0Callback() was never triggered.  After several days of troubleshooting, I discovered a possible mismatch between the startup file and the generated interrupt handler names.  In startup_stm32c092gcux.s, the following interrupt vectors are defined:  .word FDCAN_IT0_IRQHandler /* FDCAN global interrupt 0 */ .word FDCAN_IT1_IRQHandler /* FDCAN global interrupt 1 */   However, when generating code with STM32CubeMX, the following interrupt handlers are created in stm32c0xx_it.c:  void FDCAN1_IT0_IRQHandler(void) { HAL_FDCAN_IRQHandler(&hfdcan1); } void FDCAN1_IT1_IRQHandler(void) { HAL_FDCAN_IRQHandler(&hfdcan1); }   As a result, the startup file expects FDCAN_IT0_IRQHandler / FDCAN_IT1_IRQHandler, but the gen

Hi I am trying to figure out these VCAP conections.From the datasheet I could look like they are internally connected together, for this reason could avoid routing these three pads together on my board.Can anybody confirm that is the case?Thank you.

Hi Community, I am using STM32H745I-DISCO board and generated a TouchGFX project and attempted to flash/debug from CubeIDE. The flashing process fails during the erase stage. Observed Errors Initially: “Error: failed to erase memory” After enabling external loader (without initialization): Erase still fails After enabling external loader with Initialize = true: “Failed to initialize external memory” “Error in initializing ST-LINK device” In CubeProgrammer: External flash is detected when selecting loader MT25TL01_STM32H745I-DISCO However: Mass erase fails Sector erase also fails Error message: “Sector erase operation has failed… please verify flash protection”  I am using STM32CubeIDE v1.18.1 and STM32CubeProgrammer: v2.16.x I have attached screenshots. Can someone help what could be the issue? Thanks.

Hello,   Is there a way to generate code with MX2 by using the CMSIS-RTOS2 API vs the FreeRTOS API? I cannot find a setting in the FreeRTOS configuration to specify that I would like to use the CMSIS-RTOS2 API.   Thank you, -GIl

Hello Team,Believing STM32H5 series is most secure Devices , just doing comparision between H563 and H573 security aspects.Just to know PSA Certified Level 3 and SESIP will also applied to H563 device as well ( being into same Family ) ? We are more concern about firmware protection against Physical and side channel attacks.    

Hi，   vl53L0x goto sleep and wakeup to reduce power.  I used single_mode,program as follow:   I find add          sensor_init(dev,vl53_mode);            //activa  The measurement time was 600 mS. long more than not add  this function？  how  to reduce the time?      

Hi, When performing two measurements per second, how can the power consumption of the VL53L0x be reduced? Is a single measurement or continuous timed measurements preferable? I adopted continuous timed high-speed measurements, setting the measurement duration to 22 ms with a 900 ms interval between measurements, resulting in an average measured current of 19 mA (according to the specification). Based on this, I calculated the average power consumption.(22 mS × 19 mA + 5 μA × 878 mS) / 900 mS = 0.4693 mA. I don't understand why others can achieve 20 μA.

Hello everyone,I am working on my bachelor thesis about sensorless Field-Oriented Control (FOC) for a three-phase BLDC motor.At the moment, I have a NUCLEO-F303RE board, a small BLDC motor, an ESC, and a power supply. I have already generated and measured PWM/SPWM signals from TIM1 channels on the STM32, but I understand that using an ESC with a 50 Hz throttle signal is not the same as directly generating three-phase PWM for FOC.For this reason, I am considering using an X-NUCLEO-IHM07M1 motor driver expansion board with my NUCLEO-F303RE board.My question is:Can the NUCLEO-F303RE + X-NUCLEO-IHM07M1 combination be used for a sensorless FOC thesis project? More specifically, can this board act as the required three-phase motor driver/inverter stage so that I can implement or test sensorless FOC with STM32 Motor Control SDK or my own code?I would also like to know whether this combination is supported by STM32 Motor Control Workbench / MCSDK, or whether I should use another Nucleo board o

Hi everybody.I'm currently trying to use the N6 Nucleo for a personal application but am having trouble starting the debugger after initially successes. I am using the Nx_TCP_Echo_Server example, and after a couple of successful iterations my debugger stopped working entirely.I am using the VSCode extension. When I start my debug session with ST-Link GDB server it will connect to the debugger, but an error will follow in the terminal as shown ("target not responding"). After disconnecting and re-initializing the debugger I will get the following error ("error in intializing... please check power"). I get the same issues after power-cycling the board. LED 2 (Red) will then remain off until I power cycle the board after the first error.Previous issues led me to believe I re-wrote the SWD lines so I connected BOOT0 to 3.3V and used the CubeProgrammer to perform a chip erase. Specifically for the external memory since to my knowledge the N6 doesn't maintain internal memory. After the chip

Hello everyone,this is my first time building an STM32 Based Board myself.I am trying to talk to the Chip Using a CP2102 UART Bridge connected to PA9 & 10.For Reset and Boot 0 ive connected Reset (NRST) to RTS of the UART Bridge and Boot0 to its GPIO0 Pin and configured that Pin in the Bridge. I have however also tried just pulling Boot0 High and Jumping NRST to GND and then immediately connecting using STM32CubeProgrammer.Using an Oscilloscope ive found that the Magic Packet is sent to the STM32 (0x7F, 115200 Baud, Even Parity, 1 Stop) but there is no response (Tx of the STM32 stays high all the Time).PB15 is left floating, I am using the VIT6 Variant (The LQFP100 Package), its a Brand new Chip, is there any configuration required before this works?

When using a Zephyr RTOS host with PAwR synchronization response enabled, the STM32WB09 controller (observer role) reports a legacy LE Periodic Advertising Report (subevent 0x0F) while syncing to a PAwR broadcaster.The broadcaster is implemented on EFR32BG42 (SiLabs). Zephyr host reports:[00:00:02.987,453] <dbg> bt_hci_core: hci_event: event 0x3e[00:00:02.987,480] <dbg> bt_hci_core: hci_le_meta_event: subevent 0x0f[00:00:02.987,497] <err> bt_scan: The controller shall raise the latest unmasked version of the eventWhich corresponds to:LE Meta EventLE Periodic Advertising Report (legacy) The Zephyr BLE controller layer is based on stm32wb0x_ble_stack_controller_only.aDoes stm32wb0x_ble_stack_controller_only.a support:BLE 5.4 PAwR (Periodic Advertising with Responses) – Observer role?Periodic Advertising Report v2 (with subevent context)? 

I am looking for an EEPROM device that has the UID but also supports the 256-byte identification page.I was lead to believe that densities less than 1M support either/or, but greaterthan/equal to 1M does support both.However, from what I can tell from the datasheet(s), the -F version (M24M01E-F) says: "The device offers an additional 256-byte page, called the identification page. This page can be used to store sensitive application parameters, which can later be permanently locked in read-only mode."But the -F version does not have section 4.5 so it does not have UID.  datasheet for version -U (M24M01E-U) says "The device also offers an additional 256-byte identification page. This page stores a 128‑bit (16‑byte) unique factory-programmed serial number, locked in read-only mode at factory delivery."And in section 4.4 says "This is an additional 256-byte page, permanently locked in read-only mode. The user can read it by issuing the read identification page instructi

Hello,   in an earlier post it was suggested to reset the FDCAN for full error recovery using RCC_APBRSTR1.FDCANRST Bit This bit seems to be global for all FDCAN instances. Is it correct that full error recovery in one FDCAN instance is not possible without interrupting traffic in the other instance - as all (or both in case of stm32g0b1) instances have to be reset?   t

Hello all, Split from this thread: I'm using an STM32U5G9 and I need to read files from a USB stick. I don't want to use ThreadX because I have to keep this application small. How can I achieve this if UsbX and FileX are supposed to be used only with ThreadX and not in standalone mode?   Thanks for your help. Best regards, Julien

Dear community,I am looking for help to have TFM ported for nucleo_u385rg_q so that I can build the tfm secure and non secure images and do a secure boot on this board. The closest board is b_u585i_iot02a which is a stm32u5 variant. But there are many low level code required for this in trusted-firmware-m repo. Is there a work done by someone that I can use for my work? Any pointers as to how to accomplish this. Thanks in advance for your support.

Hi,How do I serve request Get Source Capabilities Extended? I'm using STM32G0B1 with a port configured as SRC.When a SINK sends the Get Source Capabilities Extended the STM PD library responds with 'Not Supported' and my code is not aware that this even did happen. Is there way to intercept and serve this request? At least the callback structure does not appear to have direct support for this. USBPD_DPM_ExtendedMessageReceived is never called. /* CAD callback definition */ static const USBPD_PE_Callbacks dpmCallbacks = { USBPD_DPM_SetupNewPower, USBPD_DPM_HardReset, USBPD_DPM_EvaluatePowerRoleSwap, USBPD_DPM_Notification, USBPD_DPM_ExtendedMessageReceived, USBPD_DPM_GetDataInfo, USBPD_DPM_SetDataInfo, USBPD_DPM_EvaluateRequest, USBPD_DPM_SNK_EvaluateCapabilities, USBPD_DPM_PowerRoleSwap, USBPD_PE_TaskWakeUp, #if defined(_VCONN_SUPPORT) USBPD_DPM_EvaluateVconnSwap, USBPD_DPM_PE_VconnPwr, #else NULL, NULL, #endif /* _VCONN_SUPPORT */ USBPD_DPM_EnterErrorR

Hello all,There might be a possible bug in HAL_UART_DeInit(). When calling HAL_UART_DeInit() when it is already initialized could lead to CPU starvation. Assume that an interrupt fires after calling __HAL_UART_DISABLE(huart); and before huart->Instance->CR1 = 0x0U; the interrupt is going to keep firing provided that some conditions are met. I was able to run a debug session and saw that only the interrupt was firing.From the ref. manual -> Note: If TE bit is reset and no transmission is on going, the TC bit is immediately set.This means that the TC bit is always going to be set and the interrupt is constantly going to fire regardless of clearing the TCF in ICR. The reference manual also mentions to ensure TC bit is being set before calling  __HAL_UART_DISABLE(huart).I am running into this issue when TE is reset and TXIE is set after calling  __HAL_UART_DISABLE(huart). This happens extremely rarely but I am able to reproduc

Looking for something to try. I'm want to recover from a failed firmware update of an MLite-880 from Elecevolve after their their 1-click installer.

Hi everybody.I have a problem with my Arduino GIGA R1  + Giga Display shield, configured by CubeMX. I configured the external RAM and flash and it works fine. I also successfully configured TouchGFX.My only remaining problem is the startup of the board. When I power it up, it doesn't boot. Even the ST-Link can't see the MCU. I must start it with BOOT_O at 0 (there is a button on the board) and it enter in bootloader mode and the DFU connection works. I can then connect the programmer, flash the Arduino firmware and after that, I can program/debug via ST-Link, I can reset it it still working. I verified the BOOT_ADDRESS it's on the good memory and not changed by Arduino firmware. As it work under reset, I presume memories are well configured.I can't find what could prevent the core to start. Both core start well on reset (verified with onboard LEDs) but nothing happen on power on. Does anyone have an idea of what could fail  or give me some hints on what to look

I am working with the MDF peripheral and find this to be a great peripheral. However the CubeMX generated code for multiple DMA based filters is not correct.I am using two filters with DMA and CubeMX generates the following descriptors:MDF_HandleTypeDef MdfHandle0;MDF_FilterConfigTypeDef MdfFilterConfig0;MDF_HandleTypeDef MdfHandle1;MDF_FilterConfigTypeDef MdfFilterConfig1;DMA_NodeTypeDef Node_GPDMA1_Channel1;DMA_QListTypeDef List_GPDMA1_Channel1;DMA_HandleTypeDef handle_GPDMA1_Channel1;DMA_NodeTypeDef Node_GPDMA1_Channel0;DMA_QListTypeDef List_GPDMA1_Channel0;DMA_HandleTypeDef handle_GPDMA1_Channel0; When starting the application I found that both MdfHandle0 and MdfHandle1 refer the same DMA handle,  handle_GPDMA1_Channel1. Likewise both handle_GPDMA1_Channel0.Parent and handle_GPDMA1_Channel1.Parent refer the same filter handle,  MdfHandle0.This is caused by generated function HAL_MDF_MspInit which is called when starting a filter using HA

hello ST Community, Is it possible to change the RDP "Read Out Protection" level from level 1 to level 0 without erasing the flash data? I've currently been able to change the level from RDP level 1 to level 0 for Nucleo-H755ZI-Q, but changing the level causes a mass erase of the flash drive. Is it possible to avoid this? If so, is there a code example? Thanks for your support.

Hello,I am working on the boot process and security of the STM32H757.For my tests, I have placed the two boot addresses for the two cores (ADD0 and ADD1 for CM7 and CM4) in the internal flash memory, with an ISR vector at each boot address :ADD0: standard ISR vector calling the standard Reset_Handler, which in turn calls the main function g_pfnVectors: .word __initial_spTop /* Use internal RAM for stack for calling SystemInit. */ .word Reset_Handler .word NMI_Handler .word HardFault_Handler .word MemManage_Handler .word BusFault_Handler .word UsageFault_Handler ... and ADD1: virtually the same ISR vector but calling BootPin_Handler instead of Reset_Handlerg_bootPinVectors: .word __initial_spTop .word BootPin_Handler .word NMI_Handler .word HardFault_Handler .word MemManage_Handler .word BusFault_Handler .word UsageFault_Handler ... Everything seems to be working properly, at least up until the security test.When RDP is set to level 0 or 1, everything is fine and
