Solved

I am using a STM32H743 processor and have ST's LwIP stack running correctly. At least to the point were I can use Hercules as a client and connect to the Nucleo and send a small block of data (24 bytes) to the Nucleo. I have set breakpoints in the code and see the packet making its way to the application. This is the standard ST implementation:void StartDefaultTask(void *argument){/* init code for LWIP */MX_LWIP_Init();/* USER CODE BEGIN 5 *//* ETH_CODE: Adding lwiperf to measure TCP/IP performance.* iperf 2.0.6 (or older?) is required for the tests.

ECMF2-40A100N6 is a 2 lines Common mode filter with ESD protection for High Speed Serial interfacehttps://www.st.com/en/protections-and-emi-filters/ecmf2-40a100n6.htmlThe input is identified as D+ to connector and D- to connector. The outputs are identified as D+ to IC and D- to IC. Can the D+ and D- sections be swapped for layout reasons?  

I'm trying to generate an s-record file that contains nothing but an array of data in flash - no executable code.  (This is used by an external tool and loaded into flash later as config data.)  I deleted everything from the project except main.c.  I also stripped everything out of the linker .ld file except the data array.  But the compiler still generates a _init and a _fini section of code.  How do I get rid of those?main.cconst unsigned char Data_Arr[] __attribute__((section (".data_arr"))) = /* Test array */{0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18}; .ld file/* Memories definition */MEMORY{FLASH (rx) : ORIGIN = 0x0801E000, LENGTH = 4K} /* Sections */SECTIONS{.data_arr :{. = ALIGN(4);KEEP (*(.data_arr))} >FLASH} List file still contains:Disassembly of section .init:0801e000 <_init>:801e000: b5f8 push {r3, r4, r5, r6, r7, lr}801e002: bf00 nopDisassembly of section .fini:0801e004 <_fini>:801e004: b5f8 push {r3, r4, r5, r6,

I cannot update my .ioc !Why has this message suddenly appeared?What software package????I've been using Cubeide for years.I have tried logging in etc. etc. as per all the forum posts.I get an OK when I use 'check connection'What is happening to ST?Chris

Posted on March 14, 2018 at 01:06Hi, I'm following a TI tutorial where the author is creating a Init Vector to determine which exception and interrupts are able to that program...He's basically creating an array of pointers to int and pass function pointers.I know that the microcontroller in that TI board is the same than the STM32F4 (Arm cortex M4).I did a overview of the manual and I couldn't figure out how to set your own Vector.Here you call it Interrupt Vector but, it's equal to their Init Vector...The memory of this vector starts at 0x0000.I just need some guidance or example to set this vector in my STM32F4Thanks in advance.#stm32f4

After facing some weird stability issues on the STM32F7 we have setup the MPU according to the recommendations presented in "MPU usage in STM32 with ARM CortexM7":https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/STM32_MPU_tips.html As far as I understand, the key point is to prevent speculative execution fetch from ExternalRAM and ExternalDevice memory regions. This is done by setup a 4GB wide low priority region and then enabling only some sub-regions (0x87) to have a range from 0x6000 0000 to 0xDFFF FFFF:Since MPU_PRIVILEDGED_DEFAULT is enabled in this example, for all disabled subsections of the MPU_REGION_NUMBER0 the default memorymap will be active (privileged access only). My question is: Could the speculative access also be prevented by disabling the privileged default memory map (PRIVDEFENA = 0). This would disallow all access (R/W) to the whole memory range at first. Memory areas used by the application would then have to be added def

Greetings. I ran into a problem, I can’t figure out how to become a polynomial if I use not 32 binary mode but in 8 bit mode. MCU STM32F072x8/xBif I use a 32-bit setting, I get the correct data and can process it on a PC, but with 8 bits it doesn’t work..  uint32_t crc32(uint8_t *data, uint16_t size){ uint32_t crc = 0; SET_BIT(CRC->CR, CRC_CR_RESET); // RESET bit for (int i = 0; i < size; i ++){ CRC->DR = * (data + i); } crc = CRC->DR; return crc; }   

Hello,U-Boot has an stboard command that writes a board ID into OTP (word 59 on STM32MP15x lines, word 60 on 13x lines).TF-A displays this board ID if a device tree label "board_id" is present in the bsec node.Could you please explain the purpose of the board ID field and how it should be used when developing a custom product/board with a STM32MP1 CPU? Is it intended that we give our products a board ID in the structure as evaluated/printed in the TF-A code?Or is this just a field for ST eval boards and irrelevant for custom product developments? Thanks.

How and where I should I edit stm32mp135f-dk.dts in yocto?? I need to edit pinmux files of kernel, I want that if I make final image files using yocto then those edited images should get include in final image using bitbake?  Or the second method is to take out developer package and edit pinmux and dtsi, dts files of linux kernel then generate uImage and dtbs then copy them in /boot folder in board. Please clear my doubts!!!

Good morning,I want to use the ILPS28QSW to measure pressure and detect water.I use the development board (STEVAL-MKI223V1K) to test the ILPS28QSW.Measuring the pressure works perfectly.I am currently working with Qvar, but i do not yet fully understand what result i should expect.When I connect the STEVAL-MKE001A I get the following Qvar data:LSB mV °C-4423186 -10.38 21.55-4480098 -10.52 21.55-4587456 -10.77 21.56-4570778 -10.73 21.56-4558559 -10.70 21.55What kind of data do I expect? Is the Qvar data correct?In addition, water can be detected using Qvar if the sensor is assembled in a plastic housing??

Hi everyone,I just picked up a STM32F746G discovery board to practice on, but I can't for the life of me get the built-in STLink to show in windows. By this I mean, I'm unable to power via mini-B and LD7 just flashes red. Once I change the jumper on JP1 to power via USB HS I can power the board on. But even then I can't detect the STLink connection. I've tried updating, downgrading, removing, reinstalling the stlink drivers (link004, link007 and link009) to no avail. Has anyone else had this issue?

Hi all,I´posted a shutdown issue with the L4981A controller and unknowingly the profile page had broken content and didn´t provide all the details. As such I got a reply with a case number from an St employee requesting my company info (which was already given) in the profile site, but have heard nothing since. Has this "dried up" ? I tried to access the profile site but the page didn´t open. All I get now from mySt is more login details on top of the one already given ! and a blank page getting no where.  It has taken me 1/2hr to get to this forum. Browser firefox, otherwise a relatively new notebook.All very disappointing. Time for customers to be better looked after.rJ

I am trying to store .bin file into eeprom(24LC256) which is required for me to flash the LCM GUI. I am trying to open the binary file in main.c as follows: #define Filepath "C:\\Users\\sushma\\STM32CubeIDE\\workspace_1.12.1\\filesizetest\\Core\\Src\\button.bin" // Open the binary file in read modeFILE *file = fopen(Filepath, "rb");if (file == NULL) {// Handle file opening errorwhile(1);} The .bin file is present in given Filepath. The file pointer is still returning NULL. I tried to use .txt format, That was also not opened in program and File pointer is returning NULL. I changed workspace and tried but I am getting the same error.I have checked the file persmissions , They are accessible and readable. Even I checked if binary file is corrupted but I can open binary file and it has contents.Could anyone please help me to resolve the issue ? or please let me know how I can store .bin file into EEPROM ?

Hello! I have noticed that the version of freertos generated by cubemx is always 10.3.1no matter which cubemx version or repository i use. is this correct? is the freertos version constant?is there a way to change this?

How to configure stv6111? Do you have any datasheet

Hello everyone,when I try to analyze my model (mynetwork.onnx) clicking on Analyze in the target selection window an error message occurs without any details. After the selection of the target in the configuration area, if I analyze the same model I receive this error: "NOT IMPLEMENTED: Convolution with multiple inputs not supported".The model mynetwork.onnx is obtained by converting a pytorch model obtained by running an algorithm downloaded from github. I use Windows 10 Home 64 bit (10.0, build 19045), STM32CubeIDE 1.13.1 and X-Cube-AI 8.1.0 (I've also tried 8.0.1).Could anyone please help me?

I've browsing around, and I could not find any documentation on how to code using the AI sub-module. I've see the- dm00570145-getting-started-with-x-cube-ai-expansion-package-for-artificial-intelligence-ai-stmicroelectronics.pdf- um2312-development-checklist-for-stm32cube-expansion-packages-stmicroelectronics.pdf- um2388-development-guidelines-for-stm32cube-firmware-packs-stmicroelectronics.pdf; and- um2526-getting-started-with-xcubeai-expansion-package-for-artificial-intelligence-ai-stmicroelectronics.pdfI could find any detailed explanation of how to use the C code.My current resources are https://www.youtube.com/results?search_query=middlewares+folder+stm32+not+being+created and just browsing the generated code, but I am lacking a more structured documentation.Am I missing some document out there?

I'm designing a automatic fan switch using a BTA26-800CWRG triac.  I'm planning on a RCD snubber.  All I've seen so far show a single diode across the resistor of the snubber.  But it seems if the snubber is snubbing an AC source there should be two parallel back to back diodes to handle both the positive and negative sources.  Can anyone confirm or shed some light on the subject?  Thanks.

Hello, I set one of GPIO to Analog mode and I want to read its value, by using HAL library. Should I just use HAL_GPIO_ReadPin to read the value?Thank you.

Hello, Is it possible to configure PA10 on STM32H735 as GPIO Analog and use it to read ADC Value ? The AN4899, 4.3.4 Analog Configuration says : Few STM32 GPIO pins can be configured in analog mode which allows the use of ADC, DAC, OPAMP, and COMP internal peripherals. To use a GPIO pin in analog mode, the following register are considered: - GPIOx_MODER to select the mode (Input, Output, Alternate, Analog) - GPIOx_ASCR to select the required function ADC, DAC, OPAMP, or COMPHowever, I don't think there is the register GPIOx_ASCR in H7 and the reference manual, Figure 77 is not using PA10.

Hi,I'm searching for UHF RFID reader IC (860-960 MHz). I found the one and only solution as "ST25RU3993". But it is NRND. So, what can I use for my new design. And is there any cheaper solution? This IC is very costly. If I ignore the cost as of now, please suggest me any other solution which is active.Thanks....

在目前的项目中，已经实现ST25R3911B作为主机，ST25R3916B作为从机，使用透明模式收发数据。我希望可以在透明模式中使用负载调制，以实现自定义的协议，我尝试使用ST25R3916B在透明模式中使用负载调制，但是没有成功，现象是将位targ=1之后，ST25R3916B的MISO没有收到主机的任何数据，且没有办法使用MOSI发送任何数据。请问ST25R3916B如何在透明模式中使用负载调制？位targ需要如何配置？Here is the machine translation:In the current project, ST25R3911B has been implemented as the host and ST25R3916B as the slave, using transparent mode to send and receive data.I hope to use load modulation in transparent mode to achieve custom protocol, I tried to use load modulation in transparent mode with ST25R3916B, but failed, the phenomenon is that the MISO of ST25R3916B did not receive any data from the host after targ=1. And there is no way to send any data using MOSI.How does the ST25R3916B use load modulation in transparent mode? How do I configure a bit targ? Best regards

On STM32F401 or any STM32,how can I read back the status of IWDG, ensuring that's it's running, as a safety measure?As I know direct counter value is not accessible, that would be ideal to see that it's not stuck. How to detect if LSI (thus IWDG) stopped running? As I found HAL/registers are mostly write only, not intended to be read back. Do I need to write this firstIWDG_KEY_ENABLE                 0x0000CCCCubeforeIWDG_KEY_WRITE_ACCESS_ENABLE    0x00005555u? // the allowed labels on this website are not really useful/specific enough.
