I want to do LoRaWAN FUOTA with STM32L4 MCU. So in the implementation it is mentioned the memory has two banks and one bank is used for previous image and one bank for new image. So my query is can we define the size of the bank?

Following Wiki page shows how to flash TF-A , u-boot , root file system to SD card with STM32CubeProgrammer.​https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer#How_to_flash_with_STM32CubeProgrammer​In the above wiki page, I can flash ​TF-A , u-boot , root file system to SD card using USB.​Now, I want to flash ​images to SD card without using USB (directly from Host Linux PC).Is there any way to ​flash ​TF-A , u-boot , root file system to SD card without using USB with STM32CubeProgrammer?Best Regards.H.

The STM32H743 has various ram blocks available as shown below:DTCMRAM - 128kBITCMRAM - 64kBRAM_D1 - 512kBRAM_D2 - 288kBRAM_D3 - 64kB1) Is it possible to combining (or a subset) of these ram block and use them as one big ram?2) Alternatively is it possible to place particular memory in a particular ram block? For example allocating a RAM_D3 to a static byte array buffer?

Hello,I am currently working on a project with the CR95HF chip. The chip has to be controlled over UART (by a STM32L4S7ZITx) and I would like a library which provides basic functions, such as being able to read a presented tag's UID and be able to read from and write to the presented tag. Does the X-CUBE-NFC3 library provide this functionality?If so, how exactly do I integrate it into my existing STM32CubeIDE project? I am aware it cannot be added through STM32CubeMx so of the whole download provided at https://www.st.com/en/embedded-software/x-cube-nfc3.html#overview what part needs integrated into my project to get the functionality described above and how do I do this?Thanks!Amy

Hi,I'm using an STM32F746ZG and writing my own custom bootloader. The bootloader will work by initially running and determining which of 2 applications to launch, both stored at different locations in the MCU's internal flash memory. How do you pass execution on to one of these 2 applications from the bootloader?Thanks,Doug Burrell

Hello, I have two boards: STM32F74G-DISCO and STM32f407VGT6 They are connected with CAN bus, but the connection is not working. On the picture in attachment is my schema. I think that my code is okay, but I am not sure about schema. I have two transceivers MCP2551. I can paste also the code, if needed.Thanks for answers.

Hi,​I'm working with the LSM6DSOX Machine Learning Core.I found the way to go from the data logs to the .ucf file, but I was wondering if there was an already available way to generate the corresponding .h file directly from Unico.I guess it would be relatively easy to code something to do it automatically, but it would be way less hassle if it already exists.

Hi everybody,I've been trying to use an IKS01A2 mounted on a Nucleo WB55 in order to test a STEVAL-MKI197V1.I installed the drivers for virtual com and was able to do a blink test on the nucleo board (programming it with mbed compiler).However, I haven't been able to have te card recognized by Unicleo-GUI.I think I should use STM32CubeMX first, but I haven't found what is the procedure in order to make everything work.The given examples use a different Nucleo board than the one I'm using.Could someone help me with a beginners friendly step by step or give me some advice?Thanks in advance and best regards!

Hi, everyone have someone know where can find the voice recognition of STM32L1 application?I just need few Japanese vocabulary to identify command, but I didn't find it. AWS didn't match my request. Could you please help me?

environment:STM32CubeIDE Ver 1.3.0STM32CubeMX Ver 5.5.0TouchGFX Ver 4.13.0Load the project created with TouchGFX in the IDE.How can I change main.c to main.cpp and let the IDE understand?Thank you.

Thank you for helping.environmentSTM32CubeIDE Ver 1.3.0STM32CubeMX Ver 5.5.0TouchGFX Ver 4.13.0I'm creating a project in TouchGFX and debugging it in the IDE.I was able to launch the IDE by double-clicking C:\TouchGFXProjects\***\STM32CubeIDE\.project and running it.(*** is the project name created by TouchGFX)However, the main function does not appear in Project Explorer.The file with the main function is in C:\TouchGFXProjects\***\Core\Src and the hierarchy is different.Is this the cause?How can I display the files related to the project such as the main function in the IDE's Project Explorer?Thank you.

I am working on the Nucleo F429ZI, and I'm working on a dual bank configuration, and I have a function that erases the flash of the other bank and loads in a new user application. I'm wondering if there's an easy way, or available function call, to find out how much memory the user application in the other bank takes up before erasing it.

Hi guys,Probably the question has been asked one million times but being new on this site, i did not find any clue. My problem is using STM32F446 on SPI1 with DMA2 addressing a device (ADIS16488) in 16bits SPI in mode 3. Polling works perfectly but seems a little time consuming for me. I tried the IT and DMA but I am facing a problem I cannot solve. When I want to perform a transfer in burst , let s say a 12x6bits array, in IT and DMA only a transfer only one halfword it succeeds, if more that one halfword, the second data on MISO is 0x0000. I think that my slave can not take the burst mode (stall time between data is 2µs min) and the second 16bits command is lost so I was wondering if there is a way to insert a little pause in the sck signal between two consecutive halfwords transfers in order to respect those 2µs.I thank you for your helpolie

I received two SensorTile.box yesterday, after the two working quite nicely for a day I started the pro mode with the STM32 CubeProgrammer. The problem is that now one of the box light up twice the blue and the green but not really starting when I plug it. The second one doesn't light up at all. I tried to plug and unplugged the USB and the battery. The frimeware was updated before I went to the pro mode. I also tried to all the boot while plugging the box. Is there any hard reset manual mode because the box is no longer detected by the computer?Thanks for your attention,Timothée Milhomme

Hi, I have my own bootloader application similar to the IAP example provided by ST that runs and determines which of 2 main applications to run then launches the application. The bootloader is working fine and the main application is working fine but when I combine them the main application always ends up hard faulting. If I launch the main application from STM32CubeMX IDE it starts fine but then if I restart the whole processor, the bootloader runs then launches the main application but it always hard faults at the same point. If I have the main application running from the beginning of flash it works fine and no hard faults.I've tried de-initing all peripherals that are used in the bootloader, that doesn't seem to make a difference. The only thing that is still running is the SysTick timer.Are there any registers that would allude to why the hard fault has occurred? How can I ensure that everything is at a nice clean state when the main application runs?I should mention that the main

I want to use a HSE BYPASS Clock Source configuration with an stm32f301k6t.Unfortunately I could not find any information in which voltage range my external oscillator should operate. Sorry if the answer is trivial, I'm no expert in electrical engineering.

Program code all generated with STM32CubeIDE 1.3.1 Build 6291_20200406_0752 (with STMCube F0 v 1.11) Program uses I2C1 on STM32030CC using AF1 GPIOB pin 6 and 7 and reads data from an HTU2X via interrupt based transfer.First it select the register :HAL_I2C_Master_Transmit_IT(&hi2c1, 0x40 << 1, aTxBuffer, 1);after that a wait loop seems needed to wait for HAL_I2C_MasterTxCpltCallbackto be called. The wait loop isHAL_Delay(40);After thatHAL_I2C_Master_Receive_IT(&hi2c1, 0x40 << 1, aRxBuffer, 3); which waits for HAL_I2C_MasterRxCpltCallback() to be called. After that no additional delay seems to be needed.The issue is, going below 40msec the HAL_I2C_Master_Receive_IT( fails (no IRQ) and going even lower to about 20msec, HAL_I2C_MasterTxCpltCallback does not get called, This is all very consistent and reproducable. Above about 40msec there are no such issues.Running this with 40msec result in about 22 successful transactions per second which is quite slow Why is su

Is the D+ pass identical to the D- path, or do I have to connect D+ and D- as appears in the datasheet?

I have a specific question and a more general one. Specifically, is there example code from ST for a TLS client runnning MBEDTLS/LWIP on STM32?Generally, is there a repository somewhere for example code?I see lots of references to example code, but for the life of me, I can not find it. Sometimes I find example code written by ST on github; but it was not posted by ST.

Hello,I'm trying to retrieve received data from web site, but I have almost 8Ko data and I only receive 2Ko. I tried to put it in loop in order to read every 2Ko but it's not working, I always have the only first part. (hope you understand my problem)Here is my code :HAL_UART_Transmit(&huart1, (uint8_t*)"AT+SHREAD=0,8236", sizeof "AT+SHREAD=0,8236", 100); for(uint8_t i = 0; i < 4; i++){     HAL_UART_Receive(&huart1, (uint8_t*)RxTx_B, 2064, 1000);     HAL_UART_Transmit(&huart2, (uint8_t*)RxTx_B, sizeof(RxTx_B), 1000);     freeBuffer(RxTx_B);}How can I read all received data at each time ?

I tried several time to download the X-CUBE-SBSFU from the ST official page. Every time I request the software I got the message that after 48h I will get it by mail. But when I check I don't find it (even in spam).Do you have any idea plz ?

Hello. I just got a ST-Link V2 and wasn't able to program/debug a STM32 MCU with it. With a fake programmer I can program succesfully. But when I try to use ST-Link V2, it gives me device not found error. I wire STDIO, SWDCLK and GND pins to the target MCU and I power up the ST-Link v2 from USB connector. Do I also wire Reset pin or anyother pin? I started to think that the one I got was broken or something... Thanks before hand.

Hello;Can anyone run STLINK V3 with CubeIDE? I can delete and load the hex code inside the processor using STLINK_Cube Programmer.But when I try to enter debug through CubeIDE, I get the following error. Anyone who has encountered this error and can find a solution?Sincelery

My project is tansplanted accordding to X-CUBE'STM32F401RE-Nucleo. main.c Functiong also is same. But when I am running ,the Program is dead. To the same time ,My warning LED that Nucle0-64 STM32L433 board' LED isn't lighting. Than I shield ---if( !demoIni() )----else-----,LED light. Finally,When I use ndef_example_read.c and ndef_example_write.c,program enter in HardFault_Handle. I also initialise my ST32L433 board through cube_MX,also According to X-CUBE'STM32F401RE-Nucleo.I want to know that NFC-CR95HF is developed ways and procedure. Thank you !
