Hi, My board consists of stm32f469 that interfaces SDRAM via FMC. I want to execute code from SDRAM. Code is loaded from internal flash to SDRAM at address 0xc0000000. But running the code from this region causes hard-fault. Is there a restriction with stm32469 to run code from SDRAM?Thanks,Ari

* I want to know how to read 2 or more sensors data in (stm32f042g6) through ADC,*stm32f042g6-> This is my controller has only one ADC (with 9 channels),Eg: Suppose Channel No :1 (temp-sensor) Channel No :2 (gas-sensor) connected,*In this scenario how i read two sensors data at a time (Suggest which method is recommended among poll,interrupt,Dmd)Examples are recommended,

I try implement a function to detect how the MCU start from, reset from watchdog or hardfault or recycle power.Watchdog reset, if the code goes to dead loop, it will trigger WD, but I have no good idea how to capture it.Recycle power, I can use PVD_IRQHandler() interrupt, but I can't find how to configure the PWR_PVD parameter from STMCube .Hardfault, I can use the HardFault_Hander() interrupt routine, it works for me.

Hello,I am looking to be able to do in-the-field firmware upgrades with the STM32G071 board. I have used the STMCubeProg tool to be able to modify the nBOOT0 user bit with the ST-Link built into the NUCLEO board. What I am looking to do is to modify nBOOT0 to 0 through the firmware on the device. Then I am assuming that I can reset the device,and then using a connected UART comms, I can update the firmware, After that, I can set the nBOOT0 pin back to 0.The issues are that I can't figure out how to modify the nBOOT0 bit in the firmware. Also, I am unsure if my STM32G071 will be able to flip its nBOOT0 pin back itself after the firmware update. I have read through the AN2606 and AN3155 and cannot find an answer to my question. Everything points back to the STM32Prog tool which I don't want to have to rely on.

Hi I'm trying to run example if memory share on Nucleo H745. But I'm getting following errors

We are porting an existing vxWorks project to STM32. I am able to import the existing source files into a STM project, but I cannot get it to compile any of the files.I have tried a variety of project types and always refresh the project after adding the files.Please provide or point me to instructions for doing this.BTW - I can successfully import examples, build and run them on a eval board.

Hello,I would like to know the behavior of the BOOT0 pin on a factory fresh STM32G474 device. I'm wondering if I can use PB6 as a general input without causing side effects if the flash option register is at factory defaults. The reference manual shows: "Reset value: 0xFXXX XXXX", but what are the *** *** values as shipped from the factory?Thank you for any insight you can provide - much appreciated!Regards,Dave

Good morning. This would be for an ST employee, please.If possible, I would like to contact the group responsible for the Sensor webinar coming up in a week or so. I'm looking to find out if there is any support information that I can get before the actual webinar takes place. One of the specific items would be which project download will be used. There appears to be two downloads with conflicting version numbers: en.fp-sns-datalog1.zip and en.stsw-stwinkt01.zip . Also, and if not already planned, it would be nice to see each module (BLE, Serial and WiFi) working as they should, up front and with the ST BLE Sensor app. I can successfully recompile and install each module, connect only with the phone, and can't get any data to transmit to wifi, BLE, file or Watson.  I've been through all of the briefs and user manual but I'm overlooking something and I'd like to find out what that is before the webinar.Thanks,TJM

Hello, i want to create a custom board for stm32 h7 series and run Free RTOS on it for a specific application. Which is the most advanced debug i can use to ensure i get all the correct debug tools on the market for this project both software and hardware. I m aware about the basic debugging like SWD or JTAG but it seems like they can be used in much more advanced ways. Also i want to program the board through DFU and USB_FS connection? will that be possible using the BOOT pins on STM32H755Bit3 processor . Thank you

STM32F469I discovery board.How to use internal flash memory address for a particular variables? it's possible ?I am struggled with this issue.i am beginner of stm32. help me.

Hi, I'm using a STM32L100RC discovery board and I'm trying to send/receive words through the Virtual Com Port (VCP). Nevertheless, even after installing the STM32 Virtual COM Port Driver (STSW-STM32102), the board is not connected as a VCP but as a USB device. I tried to reinstall everything, to change the ports used for the usb cable but nothing is working. Does someone has any idea about how to fix this issue?Thank you in advance,Jay.

Hi,how can i output the reference Voltage to PB0 or B1 at a STM32L1(51RCT6A) µC ?I've enable the "Voltage reference out" at cubeMX.At the RM0038 Figure 28, is see a second switch to PB0 or PB1, how i can enable that?THX

I would like to run Azure RTOS application on Cortex-M of STM32MP1 SOC. Is Azure RTOS available for Cortex-M of STM32MP1 devices? any example code?

I'm working on a project with version 5.2 of X-CUBE-CELLULAR and there is an new version 6.0. I tried to download it and use it to update my project but I see that folders structure is not the same, thus updating my project is difficult. What is the easiest way to do that ?

we have a spc560B-DIS board. we can program a sample from spc5 studio using STK 5.2 software on this board. in the next step, we create a new spc5 program (blinking LED ) and successfully build it. but we can not program and debug this on this board. Are there some setting for spc560B-DIS board that we do not consider?

Hi, I am using STM32H750VB Controller. I am using DMA transmit and Receive(Circular Mode) .In receive I am defining an DMA array of fixed size of 10 bytes. My problem is that when 5 bytes of data(first data) is received the array gets updated (Position 0 - 5) and when after some seconds if I receive the second data with 6 bytes the array gets updated (Position 6 to 10).Is there a way to update or reinitialize the DMA array so that if second data comes it starts from array initial position.(Position 0 to 6) . I have also tried with normal DMA mode and also Circular DMA mode. Have attached the settings screenshot.

Hi,I've configured 3 ADC channels (IN2, IN3,IN4) in DMA mode (device=STM32L475RCTX running at 80MHz) as shown:  I want to set a sample time of 6400Hz (156.25ms) so here's the TIM4 configuration In order to test the sample time I toggle an output pin in the irq callback:  Everything is okay except for the jitter on this output: This jitter is about of 5us. Why? How can avoid this? I've tried to change the DMA priority interrupt without success.thanks in advance,gaston

Hi, ​I am developing with STM8S003F3.I want to store user-specific information somewhere in the flash and read only that area with ST-LINK.Is there such a way?Regards, Gotoda

Hai,I am using stm32fo70c6 when i upload the usb_cdc code and connected with usb , it is showing in the device manager as either stm32 DFU mode or stm32 bootloader, it has not detect as a com port, if can anyone knows suggest me , how stm32f070c6 detect as a com port, in some systems it is showing as virtual com port ,some other systems it is showing as either stm32 DFU mode or stm32 bootloader, how can I overcome this error

Hello everyone, I'm working on a project that I did not create, it is finished and I have to reopen it to do some changes. The project is based on STM32L496 microcontroller with x-cube-cellular package. It connects to Azure cloud to send sensors data. What I want to do is to change the modem configuration with AT commands to have the best connection. I would like to send the "newscanmode" AT command, available in at_custom_modem_signalling_bg96.c file, but how to send the command ? Is there a function to do this ? Thanks

I have an EVSPIN32F02Q1S1 board to experiment. Each boot pin has a connection to Vcc via a diode (D1, D4, D7) - which are not mounted on the board. When driving a phase full on the pull up MOSFET breaks down about every 2.5ms. The time varies depending on other IO signals.I can not find a reference data sheet or application note about the MOSFET driver circuitry of this chip.Anybody knows how to drive this pin?If I need 100% Vcc output, is populating those diodes all that is required?What are the implications?

Dear all,I am working on STM32F413 microcontroller. I want to transmit data on UART without using any HAL function. And I want to send data in non blocking mode means on interrupt mode not in polling mode.Can anyone help me out in this?Thanks

Hi ST community,I am interrested in using the STM32F767-Nucleo board for SPI communication. My system is as follows. I have one STM32F767-Nucleo board which is my SPI slave and a Raspberry Pi which acts as SPI master device. The Raspi should read data via SPI from the Nucleo board. There is also one wire which is used from the Nucleo board to tell the Raspi when data is ready to be read. So every time data is ready the STM32 toggles this GPIO pin and the Raspi gets an interrupt and forces a read command. Now my problem is not the SPI communication, no this works very well. The problem is the GPIO pin which forces interrupts at the Raspi and after that SPI read commands for the STM32. After some time of working properly the GPIO pin does nothing for about 400ms to 500ms and I don't know why this happens (see picture GPIO_stop_working.png) . I use the DMA to transfer data from the memory to the SPI peripheral. If timer 3 generates an Interrupt (this happens every 100ms) HAL_TIM_PeriodEla
