I've discovered an interesting quirk. When trying to load the elf file with the headers shown below, STM32CubeProgrammer erases the 2kB internal flash page on the STM32G474RE (dual bank mode) at 0x08007000. It then programs in the ELF file header. This sort of makes sense; there is a "hardware information" flash page at 0x08007800. However, it is set to NOLOAD in the linker script, and so there isn't actually any data there. In general, STM32CubeProgrammer does a good job not flashing areas which are NOLOAD, but for whatever reason it decides it simply must have something at 0x08007000 in this case. In fact, if I open the .elf in STM32CubeProg, there is data loaded in the viewer. However, using objcopy to create a binary, ihex, or srec file does not emit this area (rightfully so).We can work around this issue by using .ihex instead (within STM32CubeIDE GDB sends it down to the STM32G474RE as a temporary .srec) but ideally I should just be able to use the .elf.STM32CubeProg Console Outp

Hello,I am currently working on STM32N6570-DK. I want to create static library from files inside of Application layer and then I will create user memory and code section inside of my project. Therefore, users will develop their own graphic and I/O configurations for product.When I created new N6 project, I can not enable static library option. Hence, my questions are:1) Can I use static library inside of N6 project?2) Can I create static library for N6 as other mcu groups?Best Regards,BK

Hello ST People !I'm looking for information / possiblity to use SPI (via spidev & ioctl) in Linux user space with DMA.We have to transfert lots of data (4000bytes at one time, very very often) to a fpga, very quickly and we are facing latency issue during transfert.With the help of a scope, we see dead times between spi transactions during this big packet write.So we are thinking using spi dma to unload cpu, but we need some infos/direction to look for.Maybe someone help or points me to right direction?Bon weekend!

Hello,after changing one of the BCM4/7 boot option bytes of my Nucleo STM32H755 board with STM32CubeProgrammer, I can't connect to the MCU any more. When trying to connect with STM32CubeProgrammer, I getError: Unable to read device id from ROM tableError: ST-LINK error (DEV_CONNECT_ERR) Is this related to the change in option bytes or did the board get damaged somehow?Thanks and regards,Martin

Hello there! Esteemed ST team member,I hope this message finds you well. I'm reaching out to address an issue I've encountered.I've designed a board based on the STM32H743 Nucleo board, but unfortunately, I'm facing difficulties with the USB functionality. I'm unsure if it's a matter of configuration or firmware. When I tested USB settings and functionality using the Nucleo board, everything worked seamlessly. Therefore, I'm inclined to think that the issue might lie with my board's circuit design.I would greatly appreciate any insights or assistance you could provide regarding this matter. Looking forward to your response.

Hello everyone,I am working with the NUCLEO-H753ZI and communicating with an IIM42652 accelerometer using SPI with DMA enabled. Below is the relevant part of my code:  int main(void) { /* MCU Configuration--------------------------------------------------------*/ HAL_Init(); SystemClock_Config(); /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); MX_SPI1_Init(); MX_TIM12_Init(); /* Start Timer 12 PWM */ HAL_TIM_PWM_Start_IT(&htim12, TIM_CHANNEL_2); // Prepare SPI communication txbuffer_dma[0] = REG_WHO_AM_I | 0x80; txbuffer_dma[1] = 0x00; memset(rxbuffer_dma, 0, sizeof(rxbuffer_dma)); // Start SPI communication with DMA HAL_SPI_TransmitReceive_DMA(&hspi1, txbuffer_dma, rxbuffer_dma, 4); /* Main Loop */ while (1) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_9, GPIO_PIN_SET); HAL_GPIO_WritePin(GPIOB, GPIO_PIN_9, GPIO_PIN_RESET); } }  After running this code, I checked the signals using a logic analyzer and observed th

Hi, I have managed to extract the OEMiROT project from H533 into H523 and compiled it successfully using STM32CRYPTO library since H523 does only have limited cryptography accelerator. I have modified the flash_layout.h to match my application (which is only using the non-secure image with no data image). However, the OEMiROT bootloader firmware itself is configured with secure and non-secure parts. I have been updating the postbuild.sh script to match my project structure. I am at the stage or running AppliCfg.exe and it error out on the flash layout with the following error[ERR] The script was probably invoked manually with having certain macros nested in flash_layouts.h.Please revisit the flash_layout.h file and hardcode values for the (NON-)SECURE_IMAGE_OFFSET and (NON-)SECURE_IMAGE_MAX_SIZE macrosI checked these macros and they are matching the ones in map.properties. I also tested with MCUBOOT_APP_IMAGE_NUMBER 1 and 2 with the same resultI attached the following fi

I would like to connect a 1.4uH antenna to ST25DV-I2C.The datasheet says that there is a 28.5pF capacitor inside the IC for RF interface tuning.However, when using a 1.4uH antenna, the resonant frequency shifts from 13.56MHz.How should I adjust the resonant frequency?Also, are there any application notes that describe how to adjust the resonant frequency?

 Hi, I trying to using VL53L5CX with my jetson nano.Once I want to using it with arduino uno, but uno is not possibly for using with it.So I trying to connected directly it on my jetson. I'm trying to followingVL53L5CX_Linux manual that downloaded from here.https://www.st.com/en/embedded-software/stsw-img025.html But for 3.2, I get some trouble. When I copied driver 2.0.0 folder on my jetsonand following the procedure(well, just simply use make as in manual)it shows such error like this ./menu.c: In function ‘main’:./menu.c:87:3: error: ignoring return value of ‘scanf’, declared with attribute warn_unused_result [-Werror=unused-result]87 | scanf("%s", choice);| ^~~~~~~~~~~~~~~~~~~cc1: all warnings being treated as errors Well, I'm very new with using jetson nano. So I'm not sure what's the problem.Maybe my jetson nano has some problems, that can't detect i2c connection with otherslike this lidar sensor or arduino board,this can be a problem? I'm really apprecia

Hi, I am following a course about USB bare metal, up until now I had no problems but the moment it started touching USB stuff the compiler started to give me errors, I think it's mostly that it does not recognize some definitions like USB_OTG_GlobalTypeDef even though it is in the stm32f407xx header file from the official CMSIS from ST.Note that all this code is bare metal (mostly).This is the full build log: 19:42:59 **** Incremental Build of configuration Debug for project USB_COURSE **** make -j12 all arm-none-eabi-gcc "../Src/usbd_driver.c" -mcpu=cortex-m4 -std=gnu11 -g3 -DDEBUG -DSTM32 -DSTM32F407G_DISC1 -DSTM32F4 -DSTM32F407VGTx -DSTM32F407xx -c -I../Inc -I"C:/Users/nicoc/Desktop/archivos/codigo/STM/USB_COURSE/Inc/CMSIS/Include" -I"C:/Users/nicoc/Desktop/archivos/codigo/STM/USB_COURSE/Inc/CMSIS/Device/ST/STM32F4xx/Include" -O0 -ffunction-sections -fdata-sections -Wall -fstack-usage -fcyclomatic-complexity -MMD -MP -MF"Src/usbd_driver.d" -MT"Src/usbd_driver.o" --specs=n

I'm working with a boost converter and have noticed that when resetting the device a PWM pin remains high/floating for a 100-200msI use the HRTIM with complementary inputs and deadtime insertion.If my lowside pin remains floating/high for an extended period after reset it causes a dead short and will blow up stuff.How do I set it up that on any reset or power loss the HRTIM PWM pins go low.Am I supposed to use the fault behaviour?Any help would be appreciated, thanks.

If anyone is familiar with Code Composer IDE, CCS allows me to add files to a project as links. If this is not possible, perhaps you might have suggestions of how to share common code files between projects without replicating the common code.

Hello, I have a few questions on STM32N6 capabilities for USB after reading AN4879, AN5967 and RM0486 documents: 1. AN4879 states that to be compliant with the USB 2.0 FS electrical spec, the DP+ pin must be pulled high. Does this also hold true for when working with the integrated HS PHY for 480Mbps speeds? 2. Do OTGx_TX_RTUNE pins also need to be connected via 200 ohm resistor to VSS for Hi-Speed USB device, or is that only for USB host mode? AN5967 states that for Hi-Speed USB host in section 13.3.1, but I'm not clear about USB device. 3. AN4879 also states that for USB 2.0 FS, the clock requires to be running at 48 MHz. However, in the RM0486 document, section 14.1 (RCC main features), it says that when the USBHSPHY is used the HSE frequency must be either 19.2, 20 or 24 MHz. Is this only a requirement for USB FS that the clock needs to be at 48 MHz, and for USB HS it has to be running at 24 MHz max? 4. AN5967 states that among supported USB options fo

Hi,I access the system bootloader by setting the bits nBOOT0/nSWBOOT0 = 0 and nBOOT1 = 1 in my code. I manage to connect via UART and flash my new firmware but then my MCU does not reboot because it remains in the system bootloader. How can I do this without using the JTAG port to change the values ​​of nBOOT0/nSWBOOT0/nBOOT1 so that my MCU once flashed leaves the system bootloader and reboots into my code?Thanks for your help.

Hi, I'm currently using the STMC Board Designer but seem to be unable to create a "Bridge" board. I was hoping to use this to create a temp pinout into connecting 2 IHM08-M1 power boards to a Nucleo-H755ZI-Q evaluation board. The documentation on the BRIDGE section isn't clear as well.  I tried adding a new board but am unable to select Bridge here:  Then I tried creating a .json for a Bridge board but I'm unable to import it because I'm unable to select the bridge section. Import failed due to "type board not match" which makes me assume that he's only able to import Control board since that tab is selected. Could you guys help me out into creating a Bridge board? 

I use a VL53L3 with the STSW-IMG033 Ultra Low Power API. I use the settings in the settings mentioned in AN5769 "Using the VL53L3CX under ultralow-power mode" for maximum detection under daylight: Full ROIMacro period 200Signal limit 1500Sigma limit 60Valid distance 400mmUsing interrupt mode: generate only an interrupt when these criteria are met I need reliable detection of a human standing in front of the sensor at max 400mm. Without any cover, the sensor functions just right. WIth a cover glass (I used the cover glass shipped with the VL53L3 Nucleo addon) I get strange results.The reason I used this cover glass for this test is that it is shipped by ST to use with their reference design. Upto about 200 mm the measurement is quite reliable. When the object distance is increased, the measured distance starts to decrease. Becasue of this I get "valid measurement" interrupts upto 1200mm. With another cover, the measurement can be 400mm at a distance of about 200mm so

Hello. I am working on a project that uses a STM32L496VET6 microcontroller and that can work as an USB device. The board has the following usb circuit schematic:The USB signals are connected directly to the MCU (D+ to PA12, D- to PA11, ID to PA10 and VBUS to PA9). The board is self-powered, so the USB power is not used. The VBUS goes through a voltage divider to reduce the voltage from 5V to approximately 3.14V. I configured the peripheral to work only as a device and the interruptions are also enabled. The middleware is configured to use the USB as a COM port. IssueWhen I plug the USB cable in the board, nothing happens, no interruption raises. Using a logic analyzer, I also saw that on idle, D+ is low and D- is high. When I plug the cable, D- goes low, being the unique change, nothing more happens. When I unplug, a interruption is raised and the disconnect callback function is called.Attempts to fixClock configuration: I tried different clock configurations to have 48MHz in
