I built up an application using STM32CubeMX and FreeRTOS but left BLE disabled. Now, I want to add that connectivity.I went back into CubeMX and turned on BLE with the HeartRate application. The only thing I changed were ASYNC_PRESALER and SYNC_PRESCALER so that the RTC time keeping would be correct.Now, whenever I allow appe_TI_Init() to execute, I get an IPCC_C1_RX_IT interrupt (VECTACTIVE = 0x3C) as soon as osKernelStart() is called. If I comment out the call to appe_TI_Init(), the rest of the code operates as before. Yes, I know that BLE is not running.What have I missed that causes the interrupt when it is not handled?Thanks

Hi,We are currently facing serious supply shortage issues with the MX66LM1G45GXDI00 flash memory.As a potential solution, I am considering modifying the design to use an external Quad-SPI flash memory instead of the current Octo-SPI flash.My understanding is that this change may require us to develop or modify the following:Quad-SPI flash drivers for the STM32U5G9 Flash initialization and memory-mapped access configuration Programming/firmware download utilities Production programming support Bootloader and/or application changes, if required TouchGFX/external-memory configuration, if applicableCould you please let us know whether suitable Quad-SPI flash drivers, BSP components, or programming utilities are already available that we could leverage, particularly for the STM32U5G9?I would also appreciate your comments on the key challenges and any guidelines or recommendations you may have for this development effort. In particular, I would like to understand the potential impact on memo

Dear all, I found an interesting effect using the CubeL4 and CubeMX generated files for a STM32L496 and use ADC1 and ADC3 (not simultaneously): What we do: We turn the ADCs on only when we sample data, otherwise they are turned off.  To turn the ADC off, we use HAL_ADC_DeInit which calls HAL_ADC_MspDeInit. Issue: HAL_ADC_MspInit and HAL_ADC_MspDeInit keep track of active ADCs through static variable HAL_RCC_ADC_CLK_ENABLED. Init increases the count, deinit decreases it. If, however, init and fails but we still call deinit the count wraps around to 0xFFFF FFFF - upon next init it wraps around to 0, but then the ADC clock is not turned on and initialization fails again. See the code snippets below: HAL_ADC_MspInit HAL_RCC_ADC_CLK_ENABLED++; if(HAL_RCC_ADC_CLK_ENABLED==1){ __HAL_RCC_ADC_CLK_ENABLE(); }   HAL_ADC_MspDeInit HAL_RCC_ADC_CLK_ENABLED--; if(HAL_RCC_ADC_CLK_ENABLED==0){ __HAL_RCC_ADC_CLK_DISABLE(); }   Suggestion: Check for underflow of&nbsp

I already posted this topic but I got low engagement.XIP template works on 50Mhz clock for XSPI and it works good. If I bump up the XSPI frequency to 200Mhz without modifying anything else, it fail at BOOT_Application() in FSBL. XSPI setup should remain the same for both 50Mhz and 200Mhz if I’m not mistaken.Dummy cycles are set weirdly also. I print XSPI CLK, PRESCALER and dummy cycles setup before BOOT_Application(). CLK = HAL_RCCEx_GetPeriphCLKFreq(RCC_PERIPHCLK_XSPI2); PRESCALER = (XSPI2->DCR2 & XSPI_DCR2_PRESCALER_Msk) >> XSPI_DCR2_PRESCALER_Pos; printf("FSBL CLK: %lu \r\n", CLK); printf("FSBL PRESCALER: %lu \r\n", PRESCALER); printf("FSBL Dummy: %lu \r\n", XSPI2->TCR); /* USER CODE END BSP */ /* Launch the application */ if (BOOT_OK != BOOT_Application()) { Error_Handler(); }XIP template example works (FSBL prints in FSBL, and Appli prints in APPLI)And when set at 200Mhz, it takes a while (~20s) before reaching BOOT_Application where

Hi there, can someone explain what the GP configuration of the STM32N6 is? I can only find information that the dedicated pinout is different (Datasheet Chap.7) but no more information whether this has any influence on the functionality. Is there any reason why the STM32N657H3QG is not available in “Tape and ring”  packaging?Thanks Mitja

Dear ST Community,I am working on an STM32 motor control project using MC Workbench and would like to configure one SPI interface and two UART interfaces in addition to the motor control peripherals.Is it possible to configure SPI and two UARTs while using MC Workbench?I tried configuring these peripherals by modifying the generated .ioc file in STM32CubeMX. However, when I regenerate the project/code, some of the peripheral configurations are overwritten by the MC Workbench-generated configuration.Could you please suggest the recommended approach for this use case? Specifically:Is there a supported way to configure SPI + two UARTs directly through MC Workbench? If not, what is the recommended method to add these peripherals without their configuration being overwritten? Should the peripherals be configured in the .ioc file after MC Workbench code generation, or is there another recommended integration method? Are there any specific USER CODE sections, middleware, or configuration file

Hello,I am getting a hard fault while trying to integrate TouchGFX into a Zephyr application.The application is secure-only and the screen design is very simple: it contains a single screen with one box. When I debug the application, the hard fault occurs in the touchgfx::Application constructor (so I cannot debug), which is called indirectly through:FrontendHeap& heap = FrontendHeap::getInstance();I have already tried increasing the following Zephyr configuration values (CONFIG_MAIN_STACK_SIZE and CONFIG_HEAP_MEM_POOL_SIZE).CRC is enabled. DMA2D is disabled for now — the “Use DMA2D Accelerator” option is set to No in the X-CUBE-TOUCHGFX package, to keep the setup simple and eliminate one possible source of issues.The framebuffers are aligned and placed across AXISRAM3, AXISRAM4, and AXISRAM5The setup is as custom board with:MCU: STM32N65XXZephyr version: 4.4TouchGFX version: 4.26.1Zephyr SDK: 1.0.1I would appreciate any help, suggestions, or debugging directions.Thanks in advance.

Hello everyone,I’m using Nucleo STM32N6 for a project of mine, and I used template XIP to begin with.In template XIP, clock frequency of the XSPI2 is set to 50Mhz without any prescalers, and VDDIO3 is set to 1 (1.8V). That setup works fine for XIP up to 85Mhz clock frequency, but above that at BOOT (00) it fails as soon as it tries to jump to a application. I haven’t been able to resolve this problem. Is it setup, or something with EXT_MEM middleware?In MX25 datasheet it can be seen that frequency heavily depends on dummy cycles, and 86Mhz corresponds to 8 dummy cycles, but on 200Mhz it requires 20. In EXT_MEM setup there is a 8D8D8D case where i go into during setup and it sets object to 20 dummy cycles, but I’m not sure is it successful in actually forcing that setup. Any help would be welcome. 

B-G473E-ZEST1SControl Discovery kitSTEVAL-LVLP01Power Discovery kitST offers a sensorless control solution featuring the ZeST (Zero Speed ​​Full Torque) algorithm, bundled with two Discovery kits: the B-G473E-ZEST1S Control Discovery kit and the STEVAL-LVLP01 Power Discovery kit. However, the power board has a relatively low output current (approximately 5 Arms). I would like to know if the ZeST algorithm can be implemented on a different power board that supports a higher output current.

Hello ST, I wonder if the top marking of STS10P4LLF6 is indeed 10P4L.Based on the latest datasheet (Rev 5, issued in Jan 2021), the top marking code is 10P4L.However, we received STS10P4LLF6 with “10K4L” but the date code is 2447. Could you please explain how this could happen?Best regards,

Hi, i am using the TCPP03-M20 for the first time. This device is stand alone. i have the device setup for 5V, which is all that is required. there is no power to the device initially when connected to the USB-C port. CC1c and CC2c pins are at around 1.65V. i do not see any voltage on Vbus. have attached the schematic section for this circuit. .If i apply 3.3v to Vcc_Vconn VBUS is still 0V. Any help appreciated.

I am struggling to get TouchGFX running on my custom board. The processor is the STM32H7A3RGT and I am driving a 320 pixel x 960 pixel LCD display. I have allocated a frame buffer in internal RAM and have LTDC producing PCLK, DE, VSYNC and HSYNC. I have configured my firmware using CubeMX to use FreeRTOS. I added a call to MX_TouchGFX_Process in my default task but it gets stuck on an assert. Specifically here:Call StackThe reason it gets stuck is because pxQueue->ixItemSize is not zero !ASSERT in xQueueSemaphoreTakeWhat am I missing ?Andy

We are using an STM32C091CCT6 with the internal HSI (48 MHz) configured as the system clock.Our application generates a volume-based pulse output using TIM14 in one-shot compare mode. The output pulse frequency is derived from flow rate, and the receiving equipment measures the number of pulses generated per second.

I built a low-power board using an STM32L031. The code I use to enter STOP mode and STANDBY mode is shown below.In STANDBY mode, the board consumes about 2 µA. However, in STOP mode, it consumes about 90 µA, and I am not sure why there is such a large difference.The circuit only consists of the STM32L031 and the power supply section. Could there be a problem with my code? Why is the current consumption so much higher in STOP mode than in STANDBY mode? void EnterStopMode(void){ __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_2); HAL_NVIC_ClearPendingIRQ(EXTI2_3_IRQn); HAL_SuspendTick(); HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI); SystemClock_Config(); HAL_ResumeTick();}void EnterStandbyMode(void){ __HAL_RCC_PWR_CLK_ENABLE(); __HAL_PWR_CLEAR_FLAG(PWR_FLAG_SB); HAL_PWR_EnterSTANDBYMode();}

Hi,Chip: STSPIN32G0602Q (STM32G031 core + integrated 3-phase gate driver)Board: custom BLDC driver board, powered via 115VAC through an isolation transformer into the board's own AC input; the board's onboard PFC/rectifier stage converts this to the internal DC buses (HV+ ~400V DC bus, and VBUS ~50-120V DC, which is the rail actually switched by the MOSFETs under test)Purpose of this test: end-of-line (EOL) production test — statically turning on one high-side MOSFET and one low-side MOSFET on different phases (e.g. U-high + V-low) for a short, controlled period, then checking output voltage/current, to verify each MOSFET pair switches correctly before the board ships. This is a functional pass/fail check, not normal motor operation — no continuous PWM switching or motor commutation is involved.Problem: TIM1's gate outputs never turn on. Root cause traced to: BIF (break flag) is always set, so MOE can never be enabled.What happensI start a TIM1 channel (HAL_TIM_PWM_Start + HAL_TIMEx_PW

Hi,I try to follow the instruction from this link to compile the “device-tree” again. First of all, the 3 primary components (FLASH- SOURCE- and SDK-x86 ...) are extracted under the WORKDIR, together with MyDeviceTree generated from the STMCubeMX. Next, the dedicated variables EXTDT_DIR, FWDDR_DIR, FIP_DEPLOYDIR_ROOT are set-up.I did also run the SDK environment to prepare for the next steps.Regarding “unpack and patch sources”, I follow the instruction line by line and did successfully.Then for the “regenerate the kernel DTB”, I got stuck at the line “make” the “.dtb” files. For this line, I changed the command as follow:MY_DEMO → MP15 (which is my project name) /linux → /kernel (since I couldn’t find the sub-dir “linux” in the DeviceTree directory) stm32mp135f → stm32mp157d -my_demo- → mp15→ Hence the file stm32mp135f-my_demo-mx.dtb will become stm32mp157d-mp15-mx.dtb, which matched with the stm32mp157d-mp15-mx.dts from the ../kernel directory.However I got the following errors and d

Hi,how do I start the USB DFU Bootloader with a STM32C071 Nucleo?

I tried with another board (F2 MCU) where it worked well to prove that the drivers are installed. BRMatthias 

Hi,We have a project with ST25R3916B to read a NFC-B T4T card. This driver works fine.In the same state machine I am adding support for reading a NFC-A card.
