I'm starting from the X-CUBE-SBSFU release v2.6.2, using the B-L475E-IOT01A - 2_Images_ExtFlash as a reference.  I've done the minimum porting required to run this on an STM32L4A6 target.I'm seeing an inconsistent issue where the SBSFU boots up and attempts to verify the Active Slot fw header signature, but fails.  The inconsistency seems tied to the build process, specifically the final step of building the UserApp + postbuild script to generate the combined SBSFU_UserApp.bin.On a 'good' build, I can flash the SBSFU_UserApp.bin onto the target and it will consistently boot successfully, regardless of the number of re-flash or reboot attempts.On a 'bad' build, I can flash the SBSFU_UserApp.bin onto the target and it will consistently fail to boot successfully, regardless of the number of re-flash or reboot attempts.= [SBOOT] SECURE ENGINE INITIALIZATION SUCCESSFUL= [SBOOT] STATE: CHECK STATUS ON RESETINFO: A Reboot has been triggered by a Software reset!= [SBOOT] STATE: CHECK

Hello, I am using CubeIDE v1.16.1 and I want to export a modified project from the firmware package STM32Cube_FW_WBA_V1.4.1. I modified the project directly in the corresponding example folder and it works successfully. Then I wanted to export the project. I tried different methods (copy, export & import), but I always got error messages when I tried to compile the exported project. My STM32Cube_FW_WBA_V1.4.1 firmware package is located in C:\Users\Frank\STM32Cube\Repository and I know that the projects use relative paths to the Drivers folder. But is there a way to export the project?    

Hello, I am facing an issue where the rendered frame buffer is printed on the display as gibberish pixels.I'm using the Nucleo F746ZG and interfacing it (over SPI) with an external display controller that writes to a 240*320 display. I was not able to locate the exact color depth of the display in the datasheet, but the information suggests that each pixel has 2ddot. Given RGB, I assumed 6bpp is the correct format.Initially I set up touch gfx to render a 16bpp frame buffer. With the 16bpp rendering I used the following code segment to send the rendered gibberish buffer to my display controller and get some random pixels printed.In TouchGFXGeneratedHAL.cpp:void TouchGFXGeneratedHAL::flushFrameBuffer(const touchgfx::Rect& rect) { uint32_t ibaseaddr = (uint32_t)getClientFrameBuffer(); uint16_t istride = lcd().framebufferStride(); uint16_t HParam = 1; uint16_t WParam = 1; uint16_t HScale = 100*HParam; uint16_t WScale = 100*WParam; uint16_t rot = 128;//<< rotates 90 degrees

Hello there,I would like to know where the NDEF middleware for X-NUCLEO NFC10 can be found.The X-CUBE NFC10 appears only to possess the RFAL middleware. 

I need to calibrate a VL53L4CX and have been reading UM2923. The functions described do not seem to bear any obvious relationship to the functions in the STM32Cube middleware which was generated for my project, which I find confusing. I it is not clear which functions I should be calling in order to satisfy the flow charts in UM2923. I have found essentially no other useful information about this device or its specific set of registers. I'm usually a huge fan of ST devices and documentation... The first sticking point is how to properly understand what to do with calibration settings. Am I supposed to store them in my own flash somewhere? That seems to be implied by UM2923. I can do this, but imagined the device would have its own NVM storage on board, since it is calibrated in the factory anyway. Is this the case? I thought so because the wrapper function VL53L4A2_RANGING_SENSOR_OffsetCalibration() ends by writing a data structure over the I2C interface from a function called VL53LX_s

Hello,I am working with [STM32 MCU model, e.g., STM32U5G9ZJT6Q], and I downloaded code from GitHub (link:https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/STM32U5G9J-DK2/Applications/USBX/Ux_Device_CDC_ACM ).While running the project, the code gets stuck in the tx_application_define() function, specifically in the while(1) loop after the USB initialization MX_USBX_Device_Init().Here is the relevant portion of the function:VOID tx_application_define (VOID *first_unused_memory){        UINT status = TX_SUCCESS;         VOID *memory_ptr;  if (tx_byte_pool_create( &tx_app_byte_pool,  "Tx App memory pool",  tx_byte_pool_buffer,     TX_APP_MEM_POOL_SIZE) != TX_SUCCESS)  {      while(1);  }    memory_ptr = (VOID *)&tx_app_byte_pool;    status = App_ThreadX_Init(memory_ptr);    if (status != TX_SUCCESS)   {    whil

I BOUGHT STEVAL- MKBOX PRO AND AM THINKING OF USING IT.I have a wireless function, but please tell me the status of technical conformity approval for use in Japan.There was no conformity mark on the package.

Hello,I'm designing a custom board with a LIS2DW12 accelerometer for motion detection. I want to use INT1 to send a signal to the MCU when it detects movement, which should wake up the whole system. The accel supports both i2c & SPI communication but I intend to use SPI. I would like to verify how I plan to make my connection between the accelerometer and MCU. Please refer to the images below.Note: VBAT is sourced from a 3V CR 2032 coin cellQ1) I'm aware that the datasheet mentions that to enable SPI communication, the CS pin must be set to logic '0' as seen in the image below. Is it okay if I directly connect the CS of the accel to a GPIO pin on the MCU through ACCEL_CS or should I add a pulldown resistor on the ACEEL_CS connection? Q2) The datasheet mentions using 100 nF (C6) ceramic and 10 µF (C5) aluminum decoupling capacitors for pin 9 (VDD). Is it okay if I use a 10 µF ceramic capacitor instead. I'm constrained for both real estate and budget on this project?Q3) Are

Hello ST Team,                              Currently i am using STM32H523RCT6 mcu for one of my application. Some times mcu goes into "hardfault handler/nmi handler". Can you suggest what will be reasons behind that problem.   Thanks with Regards DEEPAK

Hi,I am working on a custom ISPU code for LSM6DSO16IS and I want to generate interrupts on INT1 and INT2. I checked all the examples in x-cube-ispu/Ispu/ism330is_lsm6dso16is at main · STMicroelectronics/x-cube-ispu generates an interrupt only on INT1.Is it possible to generate interrupts on INT1 and INT2 at the same time? Thanks a lot :)Chen

Hi,i use the example BLE_p2pServer_ota with STM32WBA55. When i scan the device, i get the advertising elements in this order:I want to swap the first both elements. How and in which file can I change this order?   

Hello,I try to build a 'PDO SINK' project on B-U585I-IOT02A and I have watched the video How to build an USBPD Sink application using the X-Cube-TCPP software pack - YouTube.Issue:After build project on STM32CubeMX 6.12.0 and opened project in STM32CubeIDE 1.13.2, there is errors shows '../TCPP/App/app_tcpp.h:26:10: fatal error: usbpd_ADC_SNK.h: No such file or directory'.Could you please review attached screenshot and let me know if there is something I'm missing in my project setup.Best regards,Robert

I modified an FSBL example to get to the root of the problem (everything else being as in the example).   volatile int rrr = 0; void SGI0_IRQHandler(void) { while (1) { rrr++; }; } int main() { HAL_Init(); SystemClock_Config(); IRQ_Disable(SGI0_IRQn); IRQ_SetPriority(SGI0_IRQn, 0); IRQ_Enable(SGI0_IRQn); while(1) { GIC_SendSGI(SGI0_IRQn, 1, 0); } }   This works perfectly in thumb mode, but when I switch to ARM (that probably should give slight performance boost for my DSP task), the interrupt is stuck in Vectors section, without doing anything.The LR is weird, and I cant get my head around how is it possible that is has LR = 0x2ffe0106 (not multiple of 4)As if the core switched to thumb mode without address being odd and started executing instructions in 16 bit mode.Thanks for any advice :)

Hello together,I'm a little bit confused by the NVIC and EXTI description in the RM0503.The NVIC vector table says the RTC / TAMP interrupts are combined EXTI lines 19 & 21 (on page 302).But when looking at the EXTI line connections table (on page 309) the RTC source is on line 28 and TAMP on line 29. 

Hi, recently I had a problem using STM32CubeMX to modify the pre-configuration of an STM32F746 processor made by TouchGFX for the STM32F746G-DISCO Discovery board. I was disoriented with the configuration of a particular GPIO pin needed by my application on the Arduino connector of this discovery board (PG7), which was free but "invisible" (i.e. not listed at all) in the table of the GPIOs in the Configuration form of the Pinout & Configuration view. Undoubtely, the problem was generated by my limited experience with CubeMX, but I think that this can be a common problem with new users of the current interface. IMHO it could be a good idea to add on top of the GPIOs table in the Configuration form a checkbox to enable/disable the visualization of ALL GPIO pins, also the unused ones, as well as a "filter row" where the user can write search strings to filter the listed items (). In the current version of CubeMX, the uninitialized pins are not visible at all in the table and the "Sear

How would i send apdu to multiple detected devices? I believe I should use the rfalIsoDepPollAHandleActivation() function with different DID values. I couldn't find much documentation on DID other than it's used to determine which device to activate and that it's a logical address, could you explain?

Hi all,I am working on the ST25R100 which I would like to be able to read  a NFC tag but also to be read by a Smartphone.Is it possible to do it simultaneously or at least alternatively by switching one mode to the other?If yes what could we switch modes in less than a second?Is there some example code which is doing this?Thank you,Sylvain

Hi there, I'm working on a project to dynamically write new URL record to the ST25DV dynamic tag. Record will keep getting update every few minutes. I would like to make sure that the chip can last for 5-10 years hence the question of write cycles limitI have seen similar post and come across this documentation https://www.st.com/content/ccc/resource/technical/document/application_note/group0/c9/d8/96/0e/14/f5/4e/41/DM00436563/files/DM00436563.pdf/jcr:content/translations/en.DM00436563.pdfThis seem to indicate a 1mil write cycles at 25C and 600k at 85C. My question is: Is every URL NDEF record write count as a cycle ? I'm only writing to a single area of the memory. Does this mean that once the write cycles limit is reach. All area of the memory will not work ?  Thank you for any info. 

Could anyone help me to identify  attached smd  diode? 

  Hello, we're using the EVSPIN32G4 ST evaluation board. in this evaluation Board design with two microcontrollers (stm32f103cbt6 for debugging and STSPIN32G4 for motor control). Unfortunately, the STM32f103cbt6 microcontroller has failed!! We bought a new Micro controller IC and repaired it. the board is now working. However, it does not communicate /debugging with the MCSDK and the motor pilot software! I think any software files for the default bootloader are missing. Please give me some suggestions and solutions. thanks

There is no clear information in the reference manual about port pin configuration locking one by one. For example (desired code): void SomeFunction() { // locking pin configuration one by one LL_GPIO_LockPin(GPIOA, LL_GPIO_PIN_0); LL_GPIO_LockPin(GPIOA, LL_GPIO_PIN_1); LL_GPIO_LockPin(GPIOA, LL_GPIO_PIN_2); ... }  May I lock pin's configuration one by one, not all at once (see code below)? void OtherFunction() { // locking all pins configuration at once LL_GPIO_LockPin(GPIOA, LL_GPIO_PIN_2 | LL_GPIO_PIN_1 | LL_GPIO_PIN_0); ... } 

I have written the HSM DCF client , including "HSM Enable" and "BAF wait HSM handshake". So the host will not start until HSM releases the start flag.But, if I let HSM delaying for more than 1.5s before releasing the flag of starting the Host, the Host will not start, or it will only start after the chip is abnormal reset several times, and this process lasts for more than 10 seconds. About the watchdog of BAF, I checked that SWT2 was not enabled while HSM was delaying. This is the register content of SWT2:  About the RGM_DES, after the abnormal reset, it shows 'A software destructive reset event has occurred'. I don't know the specific reason for the reset and how to solve it, please help me answer.Thanks. 

Hello, On the ST wiki for NetX Duo [ Introduction to NETXDUO - stm32mcu ], there is the following info tag:"Information - NetX requires that Zero-copy feature that is currently supported only in the STM32H7 HAL Ethernet driver. "I have run the NetXDuo example application on the STM32H563ZI eval board and it's functioning as expected. I'm trying to understand what the limitation is for running NetX Duo on the H5 vs the H7, as this comment implies that I have to upgrade to the H7 to use the feature all together. If I choose to run NetX Duo on the H5, is there a subset of features that won't work? Is zero-copy just not available?  Thanks

Bug:CubeMX codegeneration for the RCC (clock module) may lead to hardfault during clock initialization.I have a minimal example IOC (attached).This faults during RCC initialization (in SystemClock_Config), after LL_RCC_SetSysClkSource(LL_RCC_SYS_CLKSOURCE_PLL1);This happens because the peripheral domain prescalers need to be increased BEFORE switching to the faster clock (AFAICT), this would mean moving LL_RCC_SetSysClkSource(LL_RCC_SYS_CLKSOURCE_PLL1) toward the end of the function (after LL_RCC_SetAPB4Prescaler).This is right now 100% reproducible for me, but I suspect that instruction prefetching can potentially hide/sidestep the problem: If I enable -Os optimization flags, then the problem vanishes depending on how many __NOP() instructions (0-3) are inserted directly before LL_RCC_SetSysClkSource(LL_RCC_SYS_CLKSOURCE_PLL1);.Best way to reproduce the hardfault is single-instruction-stepping over this section with the debugger (that catches it every time for me).Workaround:Use HAL l
