I`ve built st-image-weston for stm32mp157f-disco board with flutter and clang layer. Then I built SDK with:bitbake core-image-weston -c populate_sdkThen I installed SDK with .tmp/deploy/sdk/core-image-weston-openstlinux-weston-stm32mp15-disco-x86_64-toolchain-4.0.1-snapshot.shAfter that I setup environment with source /opt/st/stm32mp15-disco/4.0.1-snapshot/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi     export CC=${CLANGCC}   export CXX=${CLANGCXX}My question is how can I install a simple flutter app to my discovery board. What are the steps that I need to follow.

Hello,When I try to start a new project with stm32wl MCU, I see that LoRaWAN is locked in cubeMX. When I import one pre-configured project, I see that it is enabled, but I don't know if I have to enable some other peripherals first to enable LoRaWAN and configure it. Can someone help me understand this problem here?Bests,Isaac

We are starting a project using STM32WB MCU. We would like to minimize the power consumption while in sleep, but able to wake it up via BLE command. From the document AN5071(STM32WB ultra-low-power features overview) it says "Wakeup from this mode can also be performed by the Radio sub-system." But I didn't found any further description or example about the 'Radio sub-system'. Does the 'Radio sub-system' is same as BLE?Is there any document or example we can study?

Dears，Currently I'm working on a BLDC project, and with the MC SDK, we can control the motor.And we also want to make the MCU(STM32F4) into STOP mode to save some power, the issue is the MCU can not goes into STOP mode, anyone tried this before?​The code:void McuEnterStopMode(void) { __disable_irq(); HAL_CAN_Stop(&hcan1); HAL_SuspendTick(); HAL_TIM_Base_Stop(&htim1); HAL_TIM_Base_Stop(&htim3); HAL_NVIC_DisableIRQ(TIM1_BRK_TIM9_IRQn); HAL_NVIC_DisableIRQ(TIM1_BRK_TIM9_IRQn); HAL_NVIC_DisableIRQ(TIM3_IRQn); HAL_NVIC_DisableIRQ(TIM7_IRQn); HAL_NVIC_DisableIRQ(FPU_IRQn); htim1.Instance->CR1 &= ~(TIM_CR1_CEN); htim3.Instance->CR1 &= ~(TIM_CR1_CEN); htim1.Instance->SR = 0; htim3.Instance->SR = 0; TIM7->CR1 &= ~(TIM_CR1_CEN); TIM7->SR = 0; TIM3->CR1 &= ~(TIM_CR1_CEN); TIM3->SR = 0;   ClearFPU();   HAL_NVIC_ClearPendingIRQ(TIM1_BRK_TIM9_IRQn); HAL_NVIC_ClearPendingIRQ(TIM1_BRK_TIM9_IRQn); HAL_NVIC_ClearPendingI

Hello, i get the wrong data from my UART connections. I try to transmit the data "HELLO WORLD\r\n" from my STM32 to my PC with a UART-USB adapter. Every cycle my LED blinks the transmitted signs are "…ýQa[gwëåÿÿÿÿÿÿÿÿ{FF}«" I tried STM32F103RBT6 and STM32L476RG. My USB adapter to RS232 is also working (i changed it too).So i assume i forgot something in my code. But my code comes from the STM32CubeIDE , Baudrate is 9600(on STM32CubeIDE, windows driver for my RS232-USB adapter and on my data recieving programm).Please help me to solve my five weeks Problem^^

Is there a way to program spi flash using st-link? The spi flash which i am using is AT25SF321B.

Hello,​I am trying to repair a DELL H525AF-00 power supply that contains the CL2183 management IC. Could I get the datasheet for this IC?

When I open it with this command,less README-CHECK-GPUCheck GPU =========   GPU can be deactivated by fuse or not present in some SOC   So in case the GPU is not present, you must configure weston on pix-man by creating this file : /etc/default/weston with this content :   OPTARGS=--use-pixman   So what does this mean and what should I do?

I would make the IoT device that detect vibration of the FAN. I will use this industrial portable blower FAN . https://www.indiamart.com/proddetail/portable-blower-fan-15055431262.htmlScenario1. To saving the energy of the device, the device goes to deep sleep when FAN is not working.2. the device is activated by interrupt from iis2dh when FAN is start to working.My question is that #01.Is it possible to generate interrupt from deep sleep when vibration detected by iis2dh?#02.for more sophisticated solution, is it more good to use microphone such as MP23AB01DH ?

Hi all I am working on ABPDLNN100MG2A3 pressure sensor from honeywell which is an i2c communication, i have read the sensor data through i2c and saved it in two variable a and b the issue is how to convert the raw data to millibar, any thoughts kindly share.Thankyou

Hi I'm right now using the Nucleo-WB55RG as a Peripheral device to which the central (tablet) connects. I built most of my codebase with the CubeMX Code Generator – that means I defined all of my services and characteristics in the GUI choosing the BLE Server profile.Now as requirements change I need to add the capability of acting as a central device simultaneously.I know there is the option to choose "Router profile" as BLE Application type in CubeMX but that deletes all my settings for the server role and there is no option to define them again for the new dual topology.So my question is: How can I extend the existing codebase by the new central device functionality but keep the possibility to regenerate code with cubeMX. What is the best approach?I already tried to look into the P2P_Routeur example but it helped just a little.Thanks for any help :folded_hands:GreetingBenjamin

Does ST consider porting/providing support Automotive Grade Linux for STM32MP1's?

I'm new to ST32 series, I bought a NUCLEO-L476RG and a B-L475E-IOT01A to get started. When I plug in either of these boards, it installs itself as a ST-Dongle and ST-Virtual COM port.

I cannot get the QSPI NOR-Flash to work on my custom board using an STM32MP153CA + Adesto AT25SF128 NOR flash in U-BOOT. I'm working with 5-10-dunfell-mp1-21-11-17 files included on the 3.1.0 ecosystem.The schematic section is shown below:Is not that different from the STM32157-ev1 implementation.I activated MPU's internal pull-ups for IO[0..3] lines by configuring the pins as follows on the dts files: quadspi_pins_mx: quadspi_mx-0 { pins1 { pinmux = <STM32_PINMUX('B', 6, AF10)>; /* QUADSPI_BK1_NCS */ bias-disable; drive-push-pull; slew-rate = <1>; }; pins2 { pinmux = <STM32_PINMUX('F', 10, AF9)>; /* QUADSPI_CLK */ bias-disable; drive-push-pull; slew-rate = <2>; }; pins3 { pinmux = <STM32_PINMUX('F', 6, AF9)>, /* QUADSPI_BK1_IO3 */ <STM32_PINMUX('F', 7, AF9)>, /* QUADSPI_BK1_IO2 */ <STM32_PINMUX('F', 8, AF10)>, /* QUADSPI_BK1_IO0 */ <STM32_PINMUX('F', 9, AF10)>; /* QUADSPI_BK1_IO1 *

Hello, I am studying the STM8S208RB MCU and the SPL. I am using STVD and COSMIC, and the Nucleo-8S208RB board for testing. The below code should configure port GPIOC Pin5 and set it to high and stay high. However, LED2 turns on for only a short moment, not permanently. The STM8 Nucleo-64 board has the User LED2 on GPIO Port C, Pin 5.What is wrong with the code? Thank you!/* Configure the LED2 GPIO */ /* Reset the GPIO Pin in CR2 register */ LED2_GPIO_PORT->CR2 &= (uint8_t)(~(LED2_GPIO_PIN));   /* Output mode selection */ LED2_GPIO_PORT->ODR |= (uint8_t)LED2_GPIO_PIN; /* High level output */ LED2_GPIO_PORT->DDR |= (uint8_t)LED2_GPIO_PIN; /* Output mode */ LED2_GPIO_PORT->CR1 |= (uint8_t)LED2_GPIO_PIN; /* Push-Pull output mode */ LED2_GPIO_PORT->CR2 |= (uint8_t)LED2_GPIO_PIN; /* 10 MHz fast output */   /* Turn On LED2 */ LED2_GPIO_PORT->ODR |= (uint8_t)LED2_GPIO_PIN;

My question is regarding HAL library in STM32F103C8T6(blue Pill) , I've just started using stm32 , I've good knowledge about arduino. I am trying to make sine PWM for a single phase inverter. For that i need channel1 of timer1 to generate complementary pwm signal Which i ve done using DMA (array of duty cycles), to vary duty cycle.I've used : HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *) sinebuffer, 60); HAL_TIMEx_PWMN_Start(&htim1, TIM_CHANNEL_1);to generate PWM.but this circular DMA buffer contains values to generate 100% sine amplitude only.(max duty cycle).So to implement feedback to the project , I have to update DMA array Values (into some percentage of initial values)Now i don't know how to implement it,if there is a way like for example CCR = ( array[x] * percentage)or any other method to multiple DMA array values (1 to 100%).I will read percentage from analog pin.THANK YOU

I am using an example that i want use in my keil Project. the example is in stm32cubeide with HAL library, i am working in keil with standard peripheral. i want use.I want to change the statement of this function using standard peripheral, I know static is a classifier for Hal_statusTypeDef, how do I modify Hal_statusTypedef without using Hal?I can use "static void name_function()" ?

Board: Nucleo-144Chip: STM32L4R5ZIT6PHey all!I have a curios problem when executing code from SRAM. My firmware lies in flash and occasionally jumps to a externally loaded binary in SRAM. As the cycle count of this binary is quite crucial, I used the DWT to read the cycles and while stepping through the code I realized that when I execute code in SRAM it takes exactly 4 cycles for a simple instruction (like nop, add, it takes more cycles for load/store ops) and not 1, as you would expect. I find this behavior quite weird and I can't really explain why execution takes longer in SRAM. More details: I created a section in SRAM1 (from 0x20000000 to 0x20030000) to hold the dynamic binary. This should be fine as SRAM1 is connected to the I-Bus and the D-Bus, the only thing that rung the alarm-bells was that the reference manual (rm0432,revision 9) states on p.107, that physical remap should be enabled for maximum performance. I didn't want to do this, so I moved the section to SRAM2, where (

Hi,my system working fine from EMMC(written through cube programmer). I also have on my board an SD-Card slot and boot configuration pins. Is it possible to upgrade the system through SD-Card to EMMC via dd if=... from rootfs?How to prepare EMMC....raw file, is it possible?I try to write sd_card.....raw file using dd application to EMMC, but the system can't start. After powering on, nothing is shown on uart debug log (boot pins changes, of course).Thanks in advancedBR Michal

I supply my STM32G4 with 3.3V. The 3.3V is more like 3.246 Volt. The VREF+ is connected externally to VDDA, which is connected to the 3.246V.My VREFINT_CAL_ADDR is 1662. On the Vref channel of the ADC I measure 1465, so I calculated 3.4034V for VDDA. This is 4.8% too high.I would expect a more accurate value. I use an Agilent bench multimeter. My regular multimeter is off by less than 1% from the bench, so it is definitely the ADC that is not accurate.On another channel I measure a voltage from an opamp. The measurement is 15% lower than what I measure with my multimeter.I've initally had the ADC clock set to 32MHZ, but I lowered it to the lowest value possible and it didn't make a difference.static const float VddaNumerator = float(*VREFINT_CAL_ADDR)*VREFINT_CAL_VREF/1000;   [[maybe_unused]] static bool testAdc() { ADC_ChannelConfTypeDef sConfig = {0}; uint16_t value; float voltage;   sConfig.Rank = ADC_REGULAR_RANK_1; sConfig.SamplingTime = ADC_SAMPLETIME_640CYCLES_5;
