Solved

Some errors occurred during the model conversion process. I have provided my model file below. Cube-AI report ：NOT IMPLEMENTED: Gemm with channel first A input is not supportedIt seems to be caused by an inability to handle the transposed data, but how do I resolve this issue? Or is the transpose operator unusable?

Hello,Do you have a FDA accession number for the VL53L4CX ToF chip? I can find only the document "VL53L4 IEC 60825-1 CB test certificate (eye safety)" at the attachments and there it isn't noted. Furthermore I guess it is not the same as for the VL53L5CX.Regards Tobias

This is a long and weird one.My boss gave me a board with an STM32L433 that wouldn't communicate or do anything after power-on. After a lot of debugging and code tracing, I discovered that the function HAL_RTC_WaitForSynchro returns a HAL_TIMEOUT error code. The auto-generated code then jumps to the error handler with the infinite loop.I have checked the RTC registers, and found an anomaly that may back this up. On a functioning board, the RTC_ISR register reads 0x00000037. On the bad board, the same register reads 0x00001017. Bit 5 (RSF) being 0 on the defective board indicates that shadow registers are not synchronized.So, what can keep the RTC from synchronizing its shadow registers?I found this line in the reference manual:"The RSF bit must be cleared after wakeup and not before entering low-power mode."Now, this board distributes 24 V to some other boards. In this particular case, the supply wires to one of these other boards were swapped, nearly shorting the supply voltage. I don

Hii, I am using hrtim in stm32G474RET6 mcu, so i want to know how we generate a counter of 500ns in which i call adc in it.If somebody know about it please help me.

Posted on June 07, 2017 at 18:46I need to have a PC algorithm that produces the same result as the hardware CRC (using an F0 chip).I can produce identical results between hardware and software when doing a byte by byte crc calculation.I would like to use the word based calculation since it is much faster.However, the result produced using the word by word in the hardware CRC is different than the one produced using the byte by byte option. I've tried all combinations of bit and byte ordering on the word value in the software based calculation (taking 4 bytes at a time and re-ordering bits and bytes) but I haven't come up with a combination that works.It isn't necessary for me to have the hardware word vs byte calculation produce the same result (would be good if it did though).  However the software and hardware calculations must obviously match.Does anyone have any tips to share on this?

Hi, I set the button on the board to WAKE_UP2 to wake up from standby mode, but it doesn't work. Also, waking up through the RTC interrupt doesn't work either. The LSE source is an external crystal. This is my code: int main(void) { /* USER CODE BEGIN 1 */ /* 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 Power */ SystemPower_Config(); /* Configure the system clock */ SystemClock_Config(); /* USER CODE BEGIN SysInit */ /* USER CODE END SysInit */ /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_ICACHE_Init(); MX_USART1_UART_Init(); MX_RTC_Init(); /* USER CODE BEGIN 2 */ if(__HAL_PWR_GET_FLAG(PWR_FLAG_SBF) !=RESET) { __HAL_PWR_CLEAR_FLAG(PWR_FLAG_SBF); char *str ="Wakeup form the STANDBY MODE\r\n\n"; HAL_UART_Transmit(&huart1, (uint8_t*)str,

Hi,I am evaluating/learning the SBSFU application example on STM32WBA55CG. I have disabled the MCUBOOT_HW_ROLLBACK_PROT and generated the signed confirmed image sbsfu_app_init.bin using the imgtool.exe  without the security counter TLV using the below command. imgtool.exe sign -k root-rsa-2048.pem -S 229376 -e little -H 0x400 --pad-header --align 8 --overwrite-only -v 1.0.0 --confirm --pad sbsfu_app_init.bin The only change I made to the above command is to remove the "-s auto" and +0 from the version to ensure TLV for the security counter isn't added. However, when I run the application, the image validation fails within the bootutil_tlv_iter_begin as shown below i.e if (info.it_magic == IMAGE_TLV_PROT_INFO_MAGIC) {// fails with info.it_magic = 0x6907 if (hdr->ih_protect_tlv_size != info.it_tlv_tot) { return -1; } if (LOAD_IMAGE_DATA(hdr, fap, off_ + info.it_tlv_tot, &info, sizeof(info))) { return -1; } } else if (hdr->ih_pr

Hi!I am trying to reproduce some examples and got stuck at simple sensor.The example code is working fine on my P-Nucleo-wb55, but if I am trying to reproduce i with CubeMX i've got failedCode is simply stuck at void shci_cmd_resp_wait(uint32_t timeout){ UNUSED(timeout); UTIL_SEQ_WaitEvt(1U << CFG_EVT_SYSTEM_HCI_CMD_EVT_RESP); return;}I’ve tried to compare example ioc file and mine and can't find something Could, someone, please help me find what I've missed?

I'm using an ST-Link V2 to stream (over ITM) code coverage data from an STM32G4 via GDB Server on a PC.This works fine most of the time (for many days), but the data stream sometimes drops some of the data. Adding a delay between calls to ITM_SendChar() on the target stops the data loss, so it appears as if the ST-Link and/or its driver are sometimes unable to keep up.I'm not exactly sure how long the delay needs to be as I am not able to use timers to generate it (as this would invalidate the testing), so I've been using a simple volatile access loop:for ( volatile unsigned delay=0; delay<500; ++delay ); Based on timings and data length, that is introducing delays of about 20uS between the calls.It seems strange to me that it works without the delay most of the time, especially as the target and PC are both running the same software at the time.Is this a known limitation of the ST-Link that would be fixed with a "professional" trace probe? 

Hello,Has anyone used the USBX host code in AzRtos (not standalone)?  The system seems very flaky, and when I looked into it, it seems the Variable: _ux_system_host in file ux_host_stack_initialize.c is never initialized./* Defined USBX host variables. */ UX_SYSTEM_HOST *_ux_system_host;So the pointer to this structure = 0, which happens to be pointing at the memory location for the ITCMRAMITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64KWas the intent to run USBX with no cache, and leave the _ux_system_host structure in the ITCM RAM, or am i missing some initialization routine?Obviously, with this data structure in the ITCMRAM, it would explain why the system is flaky when the ICACHE is turned on.  However, I'm still not able to get the USB_host up and running properly even with the icache off.  (a lot of bus faults due to incorrect callback pointers in this structure)The ST examples don't seem to run either. Any help would be greatly appreciated

Hello,I'm working with a graphics output on an STM32H750-based board.My bitmap resources are stored in SQPI, and the frame buffers (double buffering) are in external SDRAM.The external SDRAM settings are as follows: TEX=1, Bufferable=1, Cacheable=1, Shareable=0SCB_CleanDCache() is being properly executed during frame buffer switching. In TouchGFX 4.24.0, I'm experiencing the following issue: Screen flickering occurs under specific conditions (image is a sample):When displaying a rounded corner window overlaid on top of a background with texAfter updating to TouchGFX 4.25.0, the screen flickering improves but still slightly exists (visible in the top right of the sample image).I believe this was improved by modifications to the TouchGFX core, but there still seems to be a bug in handling the contention between CPU and DMA2D/LTDC when accessing the frame buffer.What do you think?For reference, in both 4.24.0 and 4.25.0, the flickering disappears when the MPU setting for external SDR

I am configuring to support Stop mode 2 in the stm32_wpan configuration section in the STM32CubeMX.The following lines are generated in stm32_lpm_if.cSYSTEM_DEBUG_SIGNAL_SET(LOW_POWER_STOP2_MODE_ENTER); SYSTEM_DEBUG_SIGNAL_SET(LOW_POWER_STOP2_MODE_ACTIVE); SYSTEM_DEBUG_SIGNAL_SET(LOW_POWER_STOP2_MODE_EXIT);However, the definitions of LOW_POWER_STOP2_MODE_ENTER, LOW_POWER_STOP2_MODE_ACTIVE and LOW_POWER_STOP2_MODE_EXIT don't get generated, which are causing undefined compilation errors.I checked the expected types for these definitions, and see that these should be defined as part of the system_debug_signal_t enum inside debug_signals.h. I have tried looking for additional configurations that might generate the missing definitions but I haven't had any success so far.What should I look into or how can I generate these missing definitions? I could try to manually add these definitions to system_debug_signal_t. but then any time I re-generate with new configurations it

Dear forumI need to update a board that uses BMO055 9 axis IMU and I need to know what is the preferred ST solution that best fit this obsoleted part.I need the 3 axis gyro + 3axis accelerometer + 3 axis magnetometerIf there is a single chip solution its okay, but a dual chip solution can work as well. Thanks in advanceIgnacio

hello, I'm programming a UWB DWM1001 on stm32cubeide with a h755zi-q board.I would need the libraries for this device, do you happen to know where I can find them?

Hi all, Previously, I've been adding all paths with the used header files in the Project->Properties->C/C++ Build->Settings->MCU GCC Compiler->Include paths->Include paths (-I), like this:It has been working pretty well, until it just stopped. The last thing that I've tried to add is "${workspace_loc:/${ProjName}/Firmware/MCU/Processor/FPU/FPU_Reg}" path and the compiler doesn't see header files stored there anymore. So, if I write #include "Cortex_M4_FPU_Reg.h" in source files, the build console throws out this error:but when I write #include <FPU/FPU_Reg/Cortex_M4_FPU_Reg.h>, everything is ok.Does anyone know why Include paths (-I) worked previously, but now it stopped accepting new paths?

Hello, please, can I put the power antenna configuration to the maximum 8dBm? and how? thanks

I used the N6 to run the mobilenet_v1_0.25_224_fft_int8.tflite, input is correctly put into the input buffer, memory map activated, NPU RAM enabled, AXICACHE enabled, everything seems to be right, the input I also test the input inside the PC in python, and the model can output things right.I dot know why, but in some steps it either jumps in to HardFault_Handler (if I directly start the debugging process without any break point)or runs everything right (using some breakpoints inside the runtime and network.c) but outputs are all Nansdo you have any ideas how I can fix them ?

Hi,I have designed a custom board using STM32G431CB and TCPP03. I am trying to make as a sink device. I followed this video : https://youtu.be/cbdFHmMOMwk?si=GqcDTJeDxTsrFDiGI have successfully generated and compiled the code. Also, i enabled the GUI interface and TRACE. I am able to get the trace messages in STM32CubeMonUCPD. But unable to see the GUI interface board port, I tried refreshing it several times but no luck . Please help.Thanks in advance.

I try to get the CAN working. But currently I'm not sure what I'm missing.I use the STM32CubeIDE v1.18.0.

Hello Anyone did ever you use the MC34063ACD-TR for to power on a "MCU" at 3.3V? From datasheet it seems it needs change R1 and R2 for to obtain the goal but the figure 15 shows until 5V so..I ask you if i can use it for my application. My application is to convert  from 24V to 3.3V.

Hi there!I've created a custom STM32F411CEU6 Board with external HSE und LSE. While the HSE works when running my user program, the Bootloader hangs within boot phase (i think).When starting bootloader, BOOT0=1 und BOOT1=0. I powered direcly on VDD, no USB. I received no answer on both uarts after sending 0x7F. I also can't connect via stmcubeprogrammer. Only can only connect with stlinkv2.I think it may be a hardware issue, but I can't find a solution.Crystal 25Mhz: https://atta.szlcsc.com/upload/public/pdf/source/20240329/19D5F850207469550BEB00D7DFEDBC7A.pdfLSE:https://atta.szlcsc.com/upload/public/pdf/source/20240418/0E0FF5F0356BA3753F616001439D1416.pdf 

 I'm using the STM32H753ZI Nucleo board with USB_OTG_FS communication,and I have enabled VBUS_SENSING. I would like to detect when the physical connection is lost,but I am not sure how to do it.Could you kindly provide any reference materials or guidance on the best approach?

Hi,I am trying to minimise the error between the I2S sampling rate.You can do this pretty well in the STM32F4 because it has an independent I2SPLL (0.02% error between target sampling rate and actual rate is excellent), this is done by changing the PLLI2S N and R values. However, I do not understand why the 48kHz sample rate needs "I2S clocks (MHz)" to be around 49 MHz. Can someone explain that?
