Hello,I am trying to run OEMiRoT on STM32H503 (NUCLEO-H503RB - MB1814B).I followed the instructions specified: https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_OEMiRoT_on_STM32H503In step 6 ("Flash new User application in CLOSED state") after choosing option 1 ("Start Bootloader") in the terminal emulator, I cannot connect the board via UART/USB to the STM32CubeProgrammer.To connect the board via UART to the STM32CubeProgrammer I had to perform a reset (RESET button). However, I cannot connect the board to the STM32CubeProgrammer via USB (User USB connector - CN3). The board with the USB cable connected performs continuous restarts.

Hi,I'm evaluating the ISM330DHCX by connecting it on a board with a linux device (imx8) through I2C. (using the st_lsm6dsx - (compatible = "st,ism330dhcx") device.All of this seems to work out of the box, and I can read accelerations through IIO sysfs like so:  root@dev:/sys/bus/iio/devices/iio:device1# cat in_accel_x_raw 218 root@dev:/sys/bus/iio/devices/iio:device1# cat in_accel_x_raw 226 root@dev:/sys/bus/iio/devices/iio:device1# cat in_accel_x_raw 222 root@dev:/sys/bus/iio/devices/iio:device1# cat in_accel_x_raw 1105 root@dev:/sys/bus/iio/devices/iio:device1# cat in_accel_x_raw 210 root@dev:/sys/bus/iio/devices/iio:device1# cat in_accel_x_raw 220 root@dev:/sys/bus/iio/devices/iio:device1# cat in_accel_x_raw 226  These values also nicely change with the actual orientation. But, like in the snippet above, every once in a while, even while the device is stationary, we get a totally unexpected reading - an outlier. (In this case the 1105) I then

I am using st-flash version of 1.8.0 to flash the binary into Nucleo H563ZI. In this process i have used erase command "st-flash --connect-under-reset erase" to check whether the hardware works or not. For the erase command i got below error"st-flash 1.8.02024-07-31T16:31:55 WARN common.c: NRST is not connected2024-07-31T16:31:55 ERROR common.c: Soft reset failed: error write to AIRCR2024-07-31T16:31:55 ERROR common.c: Can not connect to target. Please use 'connect under reset' and try againFailed to connect to targetFailed to parse flash type or unrecognized flash type"I have also tried with st-link's git upstream master(1.8.0-39-gd7103ff) for testing yet the above error persists. I am using WSL2 on native windows machine.Does anyone has similarish or related issues for the STM32H563ZI target?

Greetings Everybody, I have Nucleo - F207ZG board. I have attached external 3.0 V coin battery to VBat and GND. I am configuring board for RTC peripheral. After configuring RTC time and again rechecking after 1 day the time starts to move ahead or time advances by few seconds. After 3 weeks RTC shows 15 seconds more than the actual time. Below is the code of main while loop   while (1) { if(_set_rtc_time) { RTC_CalendarConfig(); _set_rtc_time = 0; } RTC_CalendarShow(aShowTime, aShowDate); lcd_put_cur(3,0); memcpy(_BUFFER_0._BUFFER,(char *)aShowTime, 8); lcd_text_justify(&_BUFFER_0); lcd_send_string(_BUFFER_0._BUFFER_OUT); }   Below is rtc init code static void MX_RTC_Init(void) { hrtc.Instance = RTC; hrtc.Init.HourFormat = RTC_HOURFORMAT_24; hrtc.Init.AsynchPrediv = 127; hrtc.Init.SynchPrediv = 255; hrtc.Init.OutPut = RTC_OUTPUT_DISABLE; hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH; hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN; if((RCC-&gt

I am using two quadrature encoders through the STM32F411CEU6 timer encoder mode. Here is the graph for one of their CNT values:As you can see, it takes about 400ms to update the value, but when it does, it seems accurate. How can I make it so that it doesn't do this? Timer settings (the same for both):The PLL is at 98 MHz and it says the peripheral clocks are at 48 MHz, although I'm not sure if that's the right number to read. I've tried changing:- Encoder Mode- Input Filter- Some values of the Trigger Output Parameters, although not all of them I am positive that the encoders are hooked up correctly and I took a look with the oscilloscope and the signal looks good. I'm simply plotting htim3.Instance->CNT to make this chart.

Hello everyone, I'm a newbie working with STM32C031, setting up interrupt for user button (blue button) integrated on the board.I am using VS Code, GNU_ARM_GCC, and CMSIS. No hal.while setting up interrupts, interrupt priority, etc. , I am making use of CMSIS functions which use parameter IRQn_Type which defines interrupt numbers and defined interrupt number 4-15 as 7, which I do not understand.Why 7?How does shifting a "one" 7 to the left turn on interrupt 13, for example? /** \brief Enable Interrupt \details Enables a device specific interrupt in the NVIC interrupt controller. \param [in] IRQn Device specific interrupt number. \note IRQn must not be negative. */ __STATIC_INLINE void __NVIC_EnableIRQ(IRQn_Type IRQn) { if ((int32_t)(IRQn) >= 0) { __COMPILER_BARRIER(); NVIC->ISER[0U] = (uint32_t)(1UL << (((uint32_t)IRQn) & 0x1FUL)); __COMPILER_BARRIER(); } } typedef enum { /****** Cortex-M0+ Processor Exceptions Numbers *****************************

Hello @PatrickF ,Hope all is well.I need to access STGEN both in A7 core as well as M4 core. I have seen some previous posts related to STGENR register access.Credit to PatrickF for this code.#define STGENR_CNTCVL_OFF 0x0000 #define STGENR_CNTCVU_OFF 0x0004 #define STGENR_CNTCVL (*(uint32_t *) (STGENR_BASE + STGENR_CNTCVL_OFF)) #define STGENR_CNTCVU (*(uint32_t *) (STGENR_BASE + STGENR_CNTCVU_OFF))   uint32_t cntr_upper, cntr_lower; uint64_t cntr;   __HAL_RCC_STGENRO_CLK_ENABLE(); do { cntr_upper = STGENR_CNTCVU; cntr_lower = STGENR_CNTCVL; } while (STGENR_CNTCVU != cntr_upper);   cntr = ((uint64_t)cntr_upper << 32) + (uint64_t)cntr_lower;I did not implement the above code, but I was trying to see if I can read STGENR from A7 using Devmem2.I found STGENR_BASE from the manual which is 0x5A005000. I used devmem2 tool to read the lower counter (address offset = 0x0000) and upper counter(address offset = 0x0004)The devmem2 values for both are 0x0. I am n

I want to use my ADC of NUCLEO-H563ZI, but there is a problem with my ADC. ADC output does not match to input voltage. Test results are as fallows.I am using ADC2 IN1, IN2, IN3, IN5, IN6, all singled ended. And I am using 25MHz HSE OSC of NUCLEO-H563ZI instead of ST-LINK 8MHz output, and disabled ICACHE. Is there a problem with my ADC/Clock configuration settings?

Posted on April 26, 2018 at 09:34Hello all. My problem is as follows.I would like to set an event in the future, lets say 950ms, at one specific point in the code. Then I would like to set the STM32L432 in Stop2 mode, wake up the MCU near the event, lets say at 750 ms so it can wake up another device, and then do the task at 950ms.I thought that LPTIM can fire two interrupts, one related to HAL_LPTIM_CompareMatchCallback, and the other related to HAL_LPTIM_AutoReloadMatchCallback.I setup an example to see how it would work.In CubeMX I configure LPTIM1 as 'Counts internal clock events', and choose LSE as the LPTIM1 clock mux. LSE frequency is 32768 Hz, and set div2 as preescaler. So each time interval is 61.035 us. In the setup I set 'update at the end of the period' and software as trigger.In the main function after setup all the peripherals, I call to HAL_LPTIM_TimeOut_Start_IT(&hlptim1, 65535, 16383);So I set up the period as 65535, so the autoreload should occur at 4s

Hello guys !I am new at the embedded systems and I am trying figure it out ! I am using STM32F446VET7.I connected my buzzer to an GPIO pin(PB12) which has no pwm speciliaties.But my buzzer is not working when I connected to the DC signal source like 5V. So I need an PWM kinda source.When I resarch I only found source codes for PWM Generation channels with Timer. My GPIO has no timer and I cannot change my design right now. Can I do the same job with Systick timer or something like that. I just need a 1 second beep sound, nothing more.Here is my design in hardwareand the datasheet of my buzzerDo I need to generate a signal with 50% duty cycle at a frequency of 2048 Hz, if you can just give me an idea, I can research and learn how to do it. Thanks

Hello, I am developing a custom image using the layer meta-st-stm32mp in the mickledore branch, until that point, there are no problems.The problem is, since I want ti install the meta-st-x-linux-ai layer, I need to install meta-st-openstlinux first, which has several layer dependencies such as meta-qt5, and other layers. The problem I am having is, once I add the meta-st-openstlinux, the process stops, it does not even initiallizes the tasks, because the parsing process does not succeed.This is the local.conf (I did not add the recipes because I thought maybe some of my recipes did generate the problem): # This file is your local configuration file and is where all local user settings # are placed. The comments in this file give some guide to the options a new user # to the system might want to change but pretty much any configuration option can # be set in this file. More adventurous users can look at # local.conf.sample.extended which contains other examples

Hello,I've successfully used the code below to enter shutdown on a U585CIUx. It wakes up on button press and I can tell it is coming up from reset because of timestamps (based on time since startup) and terminal output that only happens during startup.Using this same code on a U585QIIx, it seems to behave as if it has entered a low power mode, just not one as low power as shutdown. When it wakes up it picks up where it left off in terms of timestamps and it does not run through startup code as expected. I'm also measuring current draw during the so-called "shutdown" - it only goes 10mA lower, but there may be some interplay with battery backups that muddies up the reading.While I don't normally test this kind of thing with the debugger, since it affects power, I did make sure that it's reaching the call to LL_PWR_SetPowerMode(LL_PWR_SHUTDOWN_MODE) and not going into some other mode.Is there something I'm missing here? It only starts drawing 10mA more current (back where it started

I used STM32F446VET7 on the board I PCB printed. When I use HSI, I can debug without any problem, but when I want to use HSE, SystemClock_Config(); function enters ErrorHandler().Can you help me?

I can not find any instruction in documents about gpio configuration in alternate function mode. For example I want to configure SPI GPIO. Examples found in the internet have different configuration. Is it unimportant to configure push pull and pull up/down parameters?

Hi allI'm working with an STM32F405 and one LSM6DSO32 and one LIS2DU12, eveyrthing works fine, but sometimes, for unknow reason, I go a strange whoamI from my captor, I got 0x20 value, I reset my mcu and it's works fine, any idea ? For my driver I use STM driver coming from stm github rep. Here is my i2c init function : I2C_HandleTypeDef hi2c1; void I2C1_Init(void){ hi2c1.Instance = I2C1; hi2c1.Init.ClockSpeed = 400000; hi2c1.Init.DutyCycle = I2C_DUTYCYCLE_2; hi2c1.Init.OwnAddress1 = 0; hi2c1.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT; hi2c1.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE; hi2c1.Init.OwnAddress2 = 0; hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE; hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE; if (HAL_I2C_Init(&hi2c1) != HAL_OK) HANDLE_CRITICAL_ERROR(ERROR_INIT_I2C); }  

  I've installed the latest Cube, 1.16.0, and configured a DAC and PWM.   The code generated fine but I wanted to add FreeRTOS.  So I added it under the Middleware dropdown and it does appear to install.   However, when I generate code I do not get any FreeRTOS support.      Previously, in 1.14.0, I would see FreeRTOS in the Middlewares directory.  Now I don't even have a Middlewares directly and there is not FreeRTOS support in my generated code.  Any ideas what is going on here? thanks,Jeff

Hello,I have an STM32L432KCU chip that's on a custom board. I have exposed SWD pins for debugging and flashing. Currently I'm only able to flash and debug the chip if I supply the STM with 2.2v from my external power supply. If I run the STM at the standard 3.3v, I get the "No STM3 target found" message when using CubeIDE, plus running CubeProgrammer, I also cannot connect to the STM to read the flash contents but can at 2.2v. These are fresh chips with no previous firmware flashed onto them, so I don't believe they should be in low power mode. Even if they happen to be in low power mode from the factory, I flash them at 2.2v with a default program to ensure they aren't running in a low power mode.After flashing the chip at 2.2v, I can supply the normal 3.3v and the chip runs just fine. However, for me to debug or flash new firmware, I can only get it to run at 2.2v. Any ideas?

I have been trying to figure out which code exactly needs to be put in SRAM4 memory region for the LPBAM tool to work. All the examples I could find only use SRAM4 and fail to explain which parts are strictly needed to be placed in that part of the memory. The most concrete explanation I could find is from a workshop on LPBAM:https://rristm.github.io/tomas_materials_v2/RRISTM/stm32u5_workshop/master/handson4.md/3I have followed that advice and was able to get my application to work only under a debug session. With no active debug session I was getting DMA linked list update error. I tried placing all object files related to my LPBAM application (the folder generated by Cube) in SRAM4 and my application still would not run without an active debug session. If like in the examples I only use SRAM4 then my application works in both cases which makes me belive that there still is some part of the code that I am missing that needs to be placed in SRAM4. Any help would be appriciated.

For a project I am using a number of timers to generate and/or monitor digital signals in a custom protocol. I stumbled upon a glitch in a timer Output Compare channel which I would like to share to find whether this is recognized and if there is a possible solution.One of the timers is used in Encoder mode to detect the start and stop of the applicable protocol. Only when one of the signals is high, a rising edge on the other signal identifies the start of a message where a falling edge while the other signal is high identifies the end of a message. When detecting a start, one Output channel 3 is set high (output compare functionality). When detecting a stop the Output Compare channels is set low again. Doing so I generate a signal which is high while a message is present.The protocol is shown in this picture. The top line is a clock signal and the second line a data signal. As shown, only during the first and the last clock, the data signal changes. During the clocks in between the d

Hi,recently I detected "complex.h" and the float complex data type for C++ project files. Since then dealing with complex numbers got very easy. I would appreciate the same ease of use for 3D float vectors, i.e. I need a float vector data type and the vector operators.Is there a comparable include for 3D vectors?THXCheersDetlef  

We developed custom PCB with CR95HF on it. PCB on itself was tested and RF circuit tuned(PCB and antenna design is based on development kit), antenna frequency is at 13.56MHz(+/- 0.5KHz), at around -60dB, uart communication working, can put CR95HF to sleep, wakeup, set register and protocols, but the problem is that we can not detect NFC tag (we use 14443A). Also we can't successfully finish calibrate process, described in datasheet, since the tag is never detected.
