Solved

I have bought a new ST-Link/V2 from Digikey a while back and have only recently gotten the chance to use it. But every time I try uploading code to my geniune WeAct F411CEU6 board using SWD I get the error code "Error: No STM32 target found!". I don't think my connections are wrong cause I followed the instructions from this website:https://waterpigs.co.uk/articles/black-blue-pill-stm32-st-link-connection/The target voltage detected is 3.14V and the firmware version is: V2J38S7.The device shows up in device manager but I'm wondering if there is anything wrong with the debugger as I can upload code via UART to the development.If anyone has any ideas please do let me know. Thank you!

・environment use board : STM32F1 Value Line Discovery Kit use debugger : TrueStudio(v9.3.0)​・questionI would like to use PendSV interrupt.To do so, I have executed the code below, but the interrupt does not occur.SCB->ICSR |= SCB_ICSR_PENDSVSET_Msk;※SCB_ICSR_PENDSVSET_Msk is (​1UL << 28)​The SCB when the following code is executed is shown below.​In the initialization, the interrupt handler is set to the vector table. No other special processing is done.Is there something missing in the procedure?

OpenStLinux 5.4 Dunfell 06 22 20 Boot chain of TF-A, U-Boot and kernel. I had forked the three .dts files with custom board names. TF-A starts fine.But in u-boot, hangs before it starts. With exact same dts contents just using original dts name as the DEVICE_TREE then u-boot runs fine. I have heard that the "compatible" property needs to be the same, which it is, but that seems to have no effect.Example u-boot build:make DEVICE_TREE=my-device-tree-name #won't bootmake DEVICE_TREE=original-device-tree-name #bootsAny ideas?

Project MX created without RTOS generate this main partMX_TouchGFX_Init(); MX_RTC_Init(); /* USER CODE BEGIN 2 */   /* USER CODE END 2 */   /* Init code for STM32_WPAN */ MX_APPE_Init(); /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { /* USER CODE END WHILE */ MX_APPE_Process();   MX_TouchGFX_Process(); /* USER CODE BEGIN 3 */ if((HAL_GPIO_ReadPin(TOUCH_IRQ_GPIO_Port,TOUCH_IRQ_Pin) == GPIO_PIN_RESET || i2cRXbuff[0]!=0) && TouchDELAY==0) if (HAL_I2C_Master_Transmit(&hi2c1, 0x5c, (uint8_t *)"\340", 1, 1) == HAL_OK) { TouchDELAY=14; HAL_I2C_Master_Receive_IT(&hi2c1, 0x5c, i2cRXbuff, 5); } } /* USER CODE END 3 */If i comment RTC and APPE = TouchgfX works.If TouchGFX commented BLE works.Is BLE RTOS compliant? Or how add (move) TouchGFX_Process into sequencer?

I am using STM32H757 dual core chip and default configuration of cubeMX generates the projects in such a way that CM7 core executes from Flash Bank1 and CM4 core executes from Flash Bank2.I modified this behavior (to have Bootloader, config data etc) such that CM4 executes from Flash Bank1 and CM7 executes from Flash Bank2 But the result is unexpected. The execution time of one my most time critical function (that executes in an ISR context) changed from 140us to 375us.Can some one comment on this that what would be the reason. If i look at the Memory organization, i can see that both Flash Banks (1 and 2) are in D1 domain. and CM4 core is in D2 domain. Any help would be appreciated.

I'm running into an issue while designing a relatively simple custom board with an L031K6T7, where after programming it the current draw exceeds 200mA and eventually breaks to the current limit of the power supply at 800mA.When I assemble the board the current draw is negligible, I have used STM32CubeMX to generate the project and use an ST-Link/V2 with a TagConnect-2030-IDC cable to program the MCU over SWD. Something is going wrong in the programming of the device and causes the current draw to be far greater than it should be. Everything I've programmed it with has been generated from CubeMX and programmed over CubeProgrammer, the power supply to the L0 is 3.34V but I've verified that it never goes above 3.4V during power-on, which is within the 3.6V limit of the L0.Any advice or recommendations on where to look would be really appreciated, I've read a fair bit of documentation but I'm still new to this and still learning.The following is a detailed description of everything I've do

Hi..My name is Anil and i am facing an issue with mems motion_GC library ie.,regarding MotionGC_Update function (&data_in, &data_out, &bias_update); for this function i am providing data.in and trying to get the calibrated data.out but not getting and the bias update is always showing 0 even for steady state and data.out values are also 0. everytime what might be the reason for this?? thanks in advance.with regards,ANIL.

Hello,I would like to encode/send and decode/receive data using Manchester communication protocol (per G.E. Thomas) between 1 and 100 kbps with a NUCLEO-L432KC. I have read many topics with multiple solutions but I'm a beginner and I'm quite confused. I'm looking for a simple and proper way to do it, without external chip. Maybe setting up a timer as counter with an interrupt should be a good idea? I would be pleased to get code examples.Thanks in advance!

I am trying to read signals from digital MEMS microphones via DFSDM peripheral and transfer it to memory with DMA on STM32H7A3. I found out that 4 channels are handled by DMA and remaining 4 with BDMA. Now I can't figure out how to get this BDMA to work. Below I placed screenshots of Cube configuration and initialization of DFSDM with DMA. I suspect that the problem can be with memory configuration in linker script, since DMA and BDMA has not access to the same memory sections. Do someone have idea if my assumptions are correct and can suggest what should I do to get it to work? 

Hi,Nowadays I am trying to send and receive data with STM32f103C8 module. In fact, my aim is only write" Hello World " one after the other in the rows below at Tera Term, by coing at STM CubeIDE, and with my some hardwares. So , first I connected this STM32f103C8 module to an FTDI programmer module and ST-Link V2. By watching some videos, I connected these 3 products's pins:STM32F103C8's Rx to FTDI's Tx,STM32f103C8's Tx to FTDI's Rx , Ground to Ground,STM32F103C8's 5V to FTDI's VCC pin, then, same legs of STM32F103C8's and ST-Link are connected to each other.I used STM CubeIDE as developement environment, and Tera Term application to test it. When I build the project at STM CubeIDE, I get no error, but then When I Debug, then Resume(F8), there is no joy at Tera Term, and at STM CubeIDE a new page is openning named 0x1fffe61c which has explanation " Break at address "0x1fffe61c" with no debug information available, or outside of program code." inside this page.Note : Baudrate is 115200

hello everyoneI am using st25ru3993.The features we want are:1. Is it possible to split the frequency down to 0.1 MHz?2. Is it possible to split the db by 0.5 or 0.1?3. I am testing the sdk and I want to check the dbm value. What class or structure can I use to check it?Please answer.

Hi,I am trying to use a custom OTA application to perform firmware updates. The code works (default Service manger OTA code from the DK) till the image size of the app uploaded is below the address 0x10057800. As soon as the firmware image exceeds this threshold, OTA does not work. I read it in the user manual that the image base needs to be fixed to a particular address, how can I do that? Also I want the image to boot from that particular new address. Please help.Thanks.

Dear Forum members,Could you please confirm if the LD1117 is specified to work with ceramic output capacitors?Unfortunately the datasheet makes no mention of capacitor type or ESR requirements.Thank you

I have a design based on the STM32MP157C (technically the Octavo SiP) which simulatenously uses PA0, PA1, ANA0, and ANA1. While measuring analog signals on the device, I'm noticing that the CPU is biasing the ANA0 and ANA1 signals -- based on a measurement across a filter resistor which has a higher voltage on the CPU side than on the measurement side.CubeMX did not generate any special pin control definitions for my use of ANA0 and ANA1; but I'm suspcious that there's either a pull up I need to disable, or the ANAx_SEL bits in SYSCFG_PMCR are not being set correctly.What pin control settings, or ADC configuration settings, should be present in the device tree for best performance of the ANA0 and ANA1 pins?

Hello, I need help to implement a function for some buttons, that every time a button is pressed a CAN message will be sent and when the button is released the CAN message will be sent again. It has to send a CAN message for falling and rising edge (doesn't matter the time between falling and rising time), and I don't want to configure GPIO as GPIO_EXTI. Thank you.

Hello,I am learning about RTOS and SEGGER tracing with a NucleoF7222ZE. For some reasons the UART2 IRQ handler is never called to get SEGGER continuous recoding.

Hi everybody,I would like to simulate a USB scanner device using libcomposite, so I modified the USB FIFO sizes in the DTS as follows:usbotg_hs{ u-boot,dm-pre-reloc; pinctrl-names = "default", "sleep"; pinctrl-0 = <&usb_otg_hs_pins_mx>; pinctrl-1 = <&usb_otg_hs_sleep_pins_mx>; status = "okay";   /* USER CODE BEGIN usbotg_hs */ phys = <&usbphyc_port1 0>; /* 0: UTMI switch selects the OTG */ phy-names = "usb2-phy"; u-boot,force-b-session-valid; u-boot,force-vbus-detection; dr_mode = "peripheral"; g-rx-fifo-size = <256>; g-np-tx-fifo-size = <256>; g-tx-fifo-size = <128 128 64 16 16 16 16 16>; /* USER CODE END usbotg_hs */ }; This allows me to open the device declaring USB packet sizes of 512 bytes instead of the maximum which would be allowed by stm32mp151.dtsi (64 bytes, the kernel panics declaring 512). After the configuration of configfs I pull up my application device-side, which borrows from the kernel example in to

I'm doing project that includes outputting an increasing/decreasing duty signal for led while also working on SPI communication, from my understanding I need to set up both timer output and spi in non-blocking mode and I can do both with HAL-s interrupt functions, as well as DMA functions. Here's where I'm confused, if both IT and DMA work in nonblocking mode and get the job done same way, what should I look out for, which one is more efficient and recommended to use?

Hello Everyone!Couple days ago, I tried to interface STM32F030R8T6 dev. board with TFT display like on the picture with ILI9486 driver.One year ago, I interfaced the same TFT with FPGA de board and everything was fine.With STM32 I tried to interface in 16-bit mode.This display doesn't has the RDX pin for reading from it. Only Write Operations.Below my code, which I've started and stuck with strange display behaviour.Problem is with colors.When I set Red Backcolor, the display is shows it as almost Black color.Green Color it shows as dark Green and Blue Color it shows correct.So all colors which are close to red, slowly become darker.I've tried to do Display Inversion mode Command, but it turned everything to Brighter color.The Blue Color it turned to yellow, Green and Yellow turned to Purple Color, White Color turned to Orange.I understand, I did something wrong, but cannot find where./* USER CODE END Header */ /* Includes ---------------------------------------------------------------

I have followed the MOOC - STM32WB workshop videos made for the STM32WB55 but I am not able to get BLE visibility in ST BLE Sensor app. I think I am not able to tune my HSE clock correctly.Please help me how to tune it for the custom made target boards?
