Hi,The external nor flash AT25XE321D is 32Mbits, support quad IO/XIP spi operation, max. 133MHz Freq. Std. JEDEC/SFDP. It is connected to STM32H7R7Z8J6 with with XSPI1 port-1 interface.I am using MX v6.116.1 to setup project for my board. By IDE v2.0.0, the project 'Boot' works from internal flash but it is failed to run 'Appli' from external AT25XE321D. And the project 'ExtMemLoader' is successfully built and deployed:File copied successfully under STM32CubeProgrammer.File copied successfully under STM32CubeIDEI tried STM32CubeProgrammer v2.21.0 to program the AT25XE321D with using the ExtMemLoader.stldr I just built, but failed too. "Error: Mass erase operation failed." See attached log for more logs.Back to my settings in MX:1) 100MHz XSPI1 clock source2) XSPI1 settings and GPIOsThere 4 memory types available and no 'custom' option. I pick the 'Macronix' as it is most close to AT25XE321D.3) ExtMemLoader settingsI also go through followings but did not help me to solve the probl

Hi,I’m new to using the STM32 plugin for VS Code, as well as to VS Code itself. I’m currently using a J-Link programmer and have successfully set it up for debugging.Could you please advise on how to setup and configure VS Code and the STM32 plugin to flash firmware onto the microcontroller for a production release (i.e., programming the device not for/in debugging mode)?Thank you for your help.

The microcontroller acquires data via SPI communication with the accelerometer. What is the risk if the data update timing of the accelerometer and the data acquisition timing of the microcontroller overlap?

Hello,I am using the ST25R3918 controlled by an MCU via RFAL, operating in NFC-F / FeliCa card emulation mode.I am monitoring the efd_o bit (bit 6) of the Auxiliary Display Register (Address: 31h) to detect when the board approaches an external reader. While I observe that efd_o stays at '1' during the initial idle state and during the first few commands, it becomes unstable (toggling between 0 and 1) after the communication sequence is completed.Sequence of operations:Receive Write Without Encryption from the reader.Send response for Write Without Encryption.Receive Read Without Encryption.Send response for Read Without Encryption.Reader terminates the communication.efd_o becomes unstable (toggling 0/1) for several hundred milliseconds. (Note: efd_o is stable at '1' during steps 1 through 4.)RFAL Configuration:discParam.devLimit = 1U;discParam.totalDuration = 60000U;discParam.techs2Find = RFAL_NFC_LISTEN_TECH_F;Questions:Is this unstable behavior of efd_o expected after a transaction

Touchgfx 4.26.0 (and was same on 4.24.0) keyboard examples are the same resolution although there are (3) resolution of display resolution selectionsThey all display the keyboard size as approx. measured 43 mm (1.7 inches) X 33mm (1.3 inches) on a 5-inch display 800 X 480 resolution. To be usable we believe the keyboard needs to be about 1.5 to 2 times larger than present. (about 25% LARGER) See details in pdf attachment

Hello,I have an ST25DV64KC chip and I’m having a problem with I2C read/write. The I2C bus is running at 100 kHz and is functional (communication with another sensor, SHT, on the bus works fine). I am also able to communicate with this NFC chip - I can read registers and read the chip’s UID correctly.The problem, however, is with reading/writing the user memory over I2C. When I try to write or read, I get NOK and the bus goes to low level and freezes. I have a main question:Q1. How is the memory actually organized? I know that the user memory has a 7-bit address of 0x53 and the system memory has an address of 0x57. I expected that the UID, which in the datasheet is listed under the System Configuration area, would be available at I2C address 0x57, but in fact it seems to be part of the EEPROM, and the UID is accessible via the user memory at I2C 0x53.So how does it actually work?? - if via I2C address 0x53 the System Configuration area is accessible at registers addresses 0x0000–0x0023

Hi,I am trying to make a basic Enhanced Advertising low power application using Arduino IDE.I use a standard P-NUCLEO WB55.I need Arduino IDE because this application is intended to be open for modifications.The current STM Documentation (https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WB_BLE_Arduino) is more than one year old and is outdated.I succeed in lighting the 3 color led by redefining their PIN OUT according with the electrical schematic. But I was not even able to get print messages (I guess the Serial is not properly define for that board).Where can I found a basic Arduino Example.I did already the update of the M0 FW which is supposed to be HCI compliant. FUS version V2.2.0.0 and STACK version v1.24.0.3.Thanks in advance.Edited to fix link.

Dear allI am using STM32H563 and interface with some CAN bus sensors to receive and sometimes send data to them. The CAN bus sensors are developed by a partner company. I developed my software refer to FDCAN_Com_IT example provided in IDE firmware package. They work fine most of time, but there is an issue has been bother me - for a few sensors, tmy software doesn't receive the message form them, it doesn't generate interrupt simply.  Don't think the sensor module is fault as they can be received by a CANUSB dongle, it seems the issues are with a few fixed sensor modules only, so i am wonder what I have done wrong to miss the message, on Logic analyser, message can be seen although sometimes it is with error, but most of time, they are fine, just doesn't reach my ISR. Regards!Ping

   Hello, I would like to ask about a question regarding “STM32N6570-DK for gesture recognition control applications.”I have downloaded the official example x-cube-n6-ai-hand-landmarks-main and reviewed the DataBrief of the development board. Since the board itself does not contain internal Flash, the file _htmresc/FSBL.PNG in the example clearly indicates two possible solutions:User APP programmed into SRAM (address: 0x3400 0400 ~ 0x3418 0000)User APP programmed into external Flash (address: 0x7008 0000 ~ 0x7FFF FFFF)Following the instructions in README.md, I executed the following steps:~make -j8~ Program the Firmware in the External FlashAfter building the application, it is necessary to add a signature to the binary file:~STM32_SigningTool_CLI -bin build/Project.bin -nk -t ssbl -hv 2.3 -o build/Project_sign.bin~ After obtaining the signed binary file, I manually programmed it to address 0x70100000.(The files ai_fsbl.hex, hand_landmark_data.hex, and palm_det

Environment: STM32L4 + 32.768K LSEFunction: Wake up and work once every hour, then enter stop2 mode. During the one-hour sleep, wake up every ten minutes to feed the external watchdog.Problem: The device resets directly when waking up every ten minutes.Current known information: The device was tested in the company for over twenty days without any issues (including restarts, freezes, etc.). After the prototypes were given to customers, problems started to occur in about 10 to 20 days. Currently, there are two failed devices. After power cycling, the devices did not return to normal. External reset also did not restore them to normal. Re-flashing the devices allows them to operate normally, and they are currently under continuous pressure testing to see if the issue will recur.Current debugging progress: When the device restarts, the nRST pin has a low-level time of less than 1ms. The 3.3V power supply pin of the MCU is stable as observed by the oscilloscope. The TP5010_DONE_Pin has a 4

I am trying to deploy encoder only transformer model on STM32 by converting pytorch model to onnx format first and then using STM toolchain (STM32 CubeAI). However, I am constantly getting this error when I analyzed the model:TOOL ERROR: cannot reshape array of size 0 into shape () I tried to debug my model but couldn't find any issue in it. Any guidance will be appreciated. Thank you.

Hi there!I already configured LwIP package and make it work on a NUCLEO-H755ZIQ following @Adam BERLINGER gude in the Knowledge base section:https://community.st.com/t5/stm32-mcus/how-to-create-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308 Well, trying to move the LwIP heap memory to a larger memory location I experienced a n unexpected issue:When I locate the heap in the DTCMRAM of the M7 core, communication will no more work at all(no ping, no tcp connection...).Locating it in D1 (AXI RAM) or D3 RAM all work as expected.I checked also the MPU configurations ad all seems correct, it seems that in DTCMRAM there is a different behavior. Just for my comprehension, there is something wrong in locating such heap into the DTCMRAM?Thanks in advance! iTTy 

Reporting that this bug is sitll present in CubeMX v6.16.1Solved: We found a bug while using Hardware JPEG. - STMicroelectronics CommunityStill JPEG_SWAP_RG, not JPEG_SWAP_RB.I wish there would be user defined section in jpeg_utils.conf.h to workaround it.And there's another bug:Every time I regenerate code, CubeMX erases Utilities/JPEG folder. So the package code has to be manually restored.

I’m working with TouchGFX in STM32CubeIDE. After creating a new project and copying over the IOC file and pin configuration from the verified design used for my custom PCB, I’m now running into errors. Some components fail to build, and I’m getting “file not found” errors for certain header files—even though the files clearly exist and I can open them in the IDE.Do you have any suggestions for fixing include paths or linker settings to resolve this?  

Hi,I want to kick ADC1 IN5 with the Timer TIM2. I'm working with CubeIDE.I select:ADC1 -> ADC_Regular_Conversion_Mode -> External Trigger Conversion Source  -> Timer 2 Trigger Out eventTIM2 ->  Trigger Output (TRGO) Parameters -> Update EventBut ADC1 does not run, Data Register is constant.If I kick ADC1 by software everything is fine, I get some noisy numbers.TIM2 is running, the count register is counting.Why does TIM2 not kick ADC1 by the TRGO event?This setup used to work fine on STM32F303. What do I miss on the STM32F429?THX CheersDetlef 

In rm0316 rev 10 for the stm32F303x, the documentation for the ABRQ bits in the CAN_TSR transmit status register states: Setting this bit has no effect when the mailbox is not pending for transmission. I am finding on my STM32F303 that setting ABRQx when the mailbox is empty will actually clear the RQCPx and TXOKx status bits in the CAN_TSR. This effect is important to note, because if you're using the TXOKx bit to determine if the message was transmitted or aborted and ABRQx was set after the mailbox finishes its transmission and becomes empty, you will think the message was successfully aborted (because TXOKx is cleared by the late abort) when it was actually transmitted. Even if you disable interrupts and check the mailbox status immediately before setting the ABRQx bit, it seems like there is still a race condition where the mailbox transmission could complete between the read and write operations, which could occasionally cause the abort to be late.  Is there a way to do this

Hi everyone,I am trying to train a large dataset in NanoEdge AI Studio, where each class is around 500 MB in size.Totally 5 class.However, I am facing limitations related to the data structure, memory usage, and training workflow in NanoEdge AI Studio. I would like guidance on:Recommended data structuring or segmentation methods for very large datasetsBest practices to handle or reduce large data sizes (windowing, feature extraction, downsampling, etc.)Any tool limitations or configuration settings to be aware ofPossible alternative approaches if direct training with such large data is not supportedIf anyone has experience training large datasets with NanoEdge AI Studio, your guidance or references would be greatly appreciated.Thank you in advance for your support.Best regards,Vijepradeepan

hi, ive noticed that hand landmarks pre built binarys uvc output does not work on the C02 revision NUCLEO-N657X0-Q but does work on the c01 rev, could anyone guide me on how to get this demo up and running ont he c02?

Hello, I was writing some code and one day a handler_reset() appears in the debug panel It is said that appears because it give the opportunity to the user to debug from the very begining. But why? if there is already the ability to set the breakpoint in the main...  I cannot assign a value to a variable.  And the other things is the fact that since it has appear I cannot longer debug and the variables make no sense. What causes all that and which is the solution??Thanks.          

Hi,I am currently facing an issue while connecting to the STM32 board using STM32CubeProgrammer. The tool consistently shows the error: "Unable to read device ID from ROM table."I have already tried the following troubleshooting steps:Performed a hardware/software/core reset using the RESET buttonVerified that all required supply voltages are correctChecked the hardware connectionsDespite this, the programmer is still unable to establish communication with the M7 core via ST-Link. It appears that the device is not being detected properly, and at the moment the board has become unusable.Could you please guide me on possible causes or additional steps I can take to resolve this issue? I would be happy to provide any further information if required.Thank you for your support.Best regards,Prathiksha

Heyho,I just changed a big PCB (1st revision working) with a H733 and added a micro SD cardholder and connected it to the SDMMC2 peripheral.Only to find out later that this #2 does NOT work with the extra IDMA controller.SDMMC1 is out of the question because I absolutely need I2SCKIN for the SAIs, and I didn't want to change the complete pin-out and PCB design (Altium says: Components on board: 1015).I'm pretty sure I've checked the RM, but maybe I oversaw something...So, is there any way to use another DMA with SDMMC2 ?Thanks in advance!

Hello Team,  I am using stm32f769 controller. I am using timer 1 channel 4 for pwm output, and my APB1 clock is 180MHZ here I am taking prescaler : 17999 and ARR=1999 and ccr=1000 for this values I can see output of pwm by generating 5hz pulses. But when I want to generate 486 pulses where my psc:17999 , ARR=19, ccr=10, I cant see any output pulses, my pwm is not responding.  (ARR+1)(psc+1)=180MHZ/frequency (ARR+1)(psc+1)=180MHZ/486 (ARR+1)(psc+1)= 370370 ARR+1=370370/18000 ARR+1=20 ARR=19   for some values upto ARR= 40 i am getting output over pwm but from values ARR=20 i am not getting output could you please help me   Thanks vamshi kumar

Dear all, I would like to connect a camera to my Nucleo F756ZG board, with the goal to send images via the ethernet port. However, this board doesn't feature a 30-pin ZIF connector nor a 22‑pin FFC connector....Apparently, the STM32 F756ZG has a "DCMI". Is this accessible on the Nucleo board as well?Which module/camera do you recommend for the Nucleo F756ZG?Would you recommend Arducam? They seem suspiciously cheapThe B-CAMS-IMX is not compatible, right?Many thanks
