Solved

Hi,I ran the SBSFU example of STM32CubeU5 following what is in the readme file without any problem. Then I disabled TrustZone but I cannot run the projects made with STM32CubeIDE, verification of the downloaded firmware fails. If I try to erase the flash memory (full chip erase) with STM32CubeProgrammer I get an error message. The error message indicates to check the flash memory protection but I have not set some flash memory protection.Thanks

I'm trying to use images through the flex button, but, when i select some images, there isn't any visual update and selection update. I tried change the "released" image and continuous with "No image" after the selection in my library images.anyone know about this problem?

Hi,Im using the Embedded Lib. I want one device to be a Target and the other the Initiator in every connection. Im trying to help me with the Ap2p example but couldnt fint anithing that tells me what the devices role is.

I used the I2C example in X-CUBE-NFC7 to write "hello the world" and wanted to read the data from the phone, but according to the above code the phone does not show any NDEF information, what should I do?/* USER CODE BEGIN Header *//** ****************************************************************************** * @file      : main.c * @brief     : Main program body ****************************************************************************** * @attention * * Copyright (c) 2021 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** *//* USER CODE END Header *//* Includes --------------------

I am using the GUI version and the command line tool to work with a device, but one of these tools has a bug. Checking which bank is use to boot from I get clearly contradictory results. See screenshot. Which tool tells me the bank used to boot from?CLI: 2.13.0GUI: 2.12.0 (update not possible; that will be yet another bug report...)

I use CR95HF for charging type electric vehicle charger. I'm going to use the T-money card for RFID.The information you need should be able to read T-money Card number, month, day, and balance check. I need to use CR95HF, so could you share a commander that I can implement?About 2,000 units will be serviced. We need to consider purchasing the reader, and if this is not implemented, we need to replace the reader.If it can be implemented with CR95HF, I would appreciate it if you could share the data Tx Rx packet commander.

STPM32's document DS10272 states that Vref is 1.18V.However, if you install the "STPM3x Evaluation Software" program provided by ST and select the EVAL-STPM32 board in Configuration, Vref is set to 1.2V.which value is correct?In addition, if you look at the list (ppm/C) of Vref Temp Compensation in the "STPM3x Evaluation Software" program, you will see the picture below. It differs from Table8 in document DS10272.Is there a reason the two are different?

Is possible to install ppp tools to connect internet using a GPRS modem ?We need pppd/chat and kernel support to get network interface, but I can't found them on OpenStLinux resources.

Hello guys,I have adapted this example from repository to work with a STM32L071CB:STM32Cube\Repository\STM32Cube_FW_L0_V1.12.2\Projects\NUCLEO-L073RZ\Examples_LL\ADC\ADC_SingleConversion_TriggerSW_DMAIt works fine until I want to add RTC and select LSE as RTC clock source.If I select LSI as clock source for RTC, it works fine.I have a loop showing the converted data every second, but when selected LSE as clock source for RTC, it does not show any results.I think it makes not sense to use LSI as clock source for RTC, so I am stuck in this point.Any idea on what might be the problem?

Hi,So I want to have a timer interrupt of 15 seconds. So I calculated the values of pre scalar and counter accordingly:Prescalar - 18356Counter - 65347I just wanted to ask if I set such values. Will it work? Cause I tried the same using an LED Toggle program but the LED didn't toggle. Also PS I'm using 3 timers and 2 External interrupts so I wonder if all collide and thats's why maybe it doesn't work?Thanks!

I want to be able to implement different projects same way as implemented from Atmega328 of Arduino. So i want to move from Arduino to STM32 for better performance and technology.

I'm trying to load some text data into a scroll list. Those texts are generated at runtime. I want to show them as list items. Also, the number of elements is not fixed. No sharply defined upper limit and lower limit for the number of elements. 

Hi all,I am using a STM32H7 and I implemented a composite usb device (CDC + AUDIO recording) using IAD interface descriptor.I can successfully configure the audio interface as type I PCM (I tested both 16 and 32 bit), but if I try to configure the audio as type I IEEE_FLOAT windows does not recognize the microphone (the device is still present in device manager under 'sound devices', but there is no input device under 'Audio inputs and outputs'.I just changed the wFormatTag field of the descriptor, leaving the bSubFrameSize=4 and bBitResolution=32.Have I to change something else?Thank you in advance,regardsArianna

I am using the STM32L433RBT6 for some uart communication project.My pcb only have STM32L433RBT6, LDO, LED, UART related circuit.I am also using the Nucleo-L433RC-P (STM32L433RCT6 )for the development.The Nucleo-L433RC is working fine for the LED4 and uart.However, STM32L433RBT6 did not work on my pcb.Therefore, I have create a simple LED switching program to test both hardware.Only enable some GPIO and the Timebase Source set as TIM1 or TIM6 (Both tested and result are the same)CODE:int main(void){ /* USER CODE BEGIN 1 */ __disable_irq(); /* USER CODE END 1 */ /* MCU Configuration--------------------------------------------------------*/ /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ /* USER CODE END SysInit */ /* Initialize all configured pe

Hello, community.So, we are using STM32F753 and activated the LWIP library from the CubeMx.We use a UDP socket to send strings (used as commands for our own made CLI protocol).When reading the Rx buffer in the STM, we see that the strings are sometimes received wrong.For example, we send the following strings over the UDP (the content itself is not important):"ver 4d" - Received correctly in the Rx buffer"pwmgen 100 ef" - Received as "pwer" (some kind of a mix with the previous packet)This mix causes misreading of the string and therefore the CLI protocol not working.We hope to find some direction to the solution.If any more details are needed, I'll be happy to provide them. Thanks,Raz

I have the options for : FreeRTOS_Plus_TCP lwIP 2.1.3 (recommended to upgrade to this based on the official website) lwIP 2.1.2 (comes with the CUBEIDE).I need a robust and stable stack.

starting IDE , stays here:only kill with taskmanager possible.problem exist when starting IDE today, yesterday and before was no problem.yesterday i closed it as usual and shut down PC.today - no start. but when i choose other workspace, it is starting.

How do I use the i2c example in X-Cub-NFC7 for I2C to RF fast transfer mode, and the MB_CRTL_Dyn register cannot be found in the STM32 CUBE IDE

lib_NDEF for st25dv04k to store the ndef format and can read it with my phone. Is there a relevant code to refer to?

Hello,Here's the context of my issue.I'm using buildroot 2022.11 to build a rootfs for a custom stm32mp157 board using a LCD display;the Linux kernel is 5.10.116 (https://github.com/STMicroelectronics/linux/tree/v5.10-stm32mp);the GUI app is built using the Qt5.15 QML framework.After the buildroot team upgraded the gcnano binaries package to v6.4.7 I'm facing flickering issues with the display. To figure out if the gcnano binaries are the root cause, I manually downgraded the gcnano to v6.4.3 in which the flickering issue is not present.I can confirm that the same rootfs/kernel with the gcnano binaries 6.4.3 has no flickering issue.Find attached to this post two videos :one showing that everything works fine with gcnano 6.4.3;one showing the flickering issue with gcnano 6.4.7.The display is mandatory for our product and we can not accept flickering issues like this one.How can we fix this issue ?Let me know if you need more traces or tests.Best RegardsAlexandre Gambier

Hello,I am trying to build a NFC project that receives 3 different ADC data from the MCU side (stm32l031k5) to the mobile phone.However, there is a critical problem that:NFC reading is too slow. There is a term like few seconds to read new text tag.The values for the ADCs are not renewed and the text tag stays same. (not always but most time, it happens)I am sharing my NFC code here.void MX_NFC7_NDEF_URI_Process(void) { char s1[200];  sprintf(s1, "%d %d %d %d %d %d %d %d %d %d %d %d %d %d %d", vol1[0], vol2[0], vol3[0], vol1[1], vol2[1], vol3[1], vol1[2], vol2[2], vol3[2], vol1[3], vol2[3], vol3[3], vol1[4], vol2[4], vol3[4]); /* Init ST25DVXXKC driver */ while (NFC07A1_NFCTAG_Init(NFC07A1_NFCTAG_INSTANCE) != NFCTAG_OK); /* Reset Mailbox enable to allow write to EEPROM */ NFC07A1_NFCTAG_ResetMBEN_Dyn(NFC07A1_NFCTAG_INSTANCE); NfcTag_SelectProtocol(NFCTAG_TYPE5); /* Check if no NDEF detected, init mem in Tag Type 5 */ if (NfcType5_NDEFDetection() != NDEF_OK) { CCFileStruct.MagicNu

Hello Support TeamI am working on a single-phase EV charging product. and I have seen a certain metering solution on the STM website.For Communication and Application purposes, we selected the below MCU1. STM32G484QET62. STM32G473VET6 3. STM32G491RET6I have some queries regarding the Complaint and certification related below I mentioned.1. I refer to this document ("x-cube-classb.pdf"). STM32G491RET6 does have not a Class B lib. am I right?2. STM32G473VET6 and STM32G484QET6 have HAL Class B libraries so In STM IDE how to use this lib?3. Is it certified IEC 60730 and UL1998 Safety Standard Compliance?if the selected MCU part is not certified certain certification so can you suggest me another STM solutionThanksHiren R. Thumar

Hi,After compiling my project I noticed that I have the flash on my H743 is almost full. When I checked the Memory Details under the Build Analyser I found that all of my screen functions repeated two times. The attached sreenshot shows more clearly what I mean. Could anyone tell if it is a necessity for some reason or am I doing something wrong? Many thanks,Namik

I have been trying to read a memory area as follows on windows power shell:.\STM32_Programmer_CLI.exe -c port=SWD -r8 0x08080000 8 -r8 0x08080C00 8but that triggers a reset of the device. I do not want a device reset, I just want to read the memory as specified. How to do that?

Hi! I don't know if this is the right place to ask this question and it may seem stupid but I am a beginner and have been trying to resolve this for one day.I am receiving one byte of data through UART to Rxdata, I want to copy this one byte to a 10 bytes buffer. I used this function:uint8_t Rxdata[1];uint8_t* Buffer[10];int head=0;memcpy(Buffer[head],Rxdata,1);head++;If someone can help me with this I would be grateful. And if you have also good explanation of variable types (It is still not very clear in my head)Thank you!
