Hi,I'm working on a STM32h747 dual core and I'm trying to put the CM4 to sleep so that it wakes up only on a CM7 event.I used _WFE on CM4 and _SEV on CM7 but the CM4 is never wake up. I release a HSEM directly after WFE in CM4 to notify the CM7 that ...
Hello everyone, I’ve recently acquired two STM32H747I-DISCO boards to experiment with USB High-Speed host functionality, specifically using the ux_host_hub_hid_msc example (v3.3.0) provided in the STM32CubeIDE. My goal is to test the Mass Storage Cla...
Hii Team, I'm using STM32G070RBT6 MCU to communicate with ADS124S06. I've configured the SPI on the MCU for Mode1 and GPIOs CS, RST, START pins as output (NO pull up/ pull down) and DRDY as input (NO pull up/ pull down). GPIO Configuration:SPI Config...
Hello everyone,I'm using AZURERTOS on my STM32F407 microcontroller. My goal is to use the FPU to perform some mathematical operations (FFT, etc.). Could you help me figure out how to activate the FPU and how to tell when it's active, taking into acco...
STM32H523HEYX Flash Write Issue1.I’m currently working on a project using the STM32H523HEYX.I'm using STM32CubeIDE, and the firmware libraries are up to date.I’m also using STM32 X-CUBE-FREERTOS.I’m trying to write data to Flash memory using the foll...
Hi everyone,I’m setting up LVGL on a custom PCB using an STM32H747BIT MCU. The display is connected via LVDS, and I’m using DMA2D for transferring the framebuffer to the screen.The issue I’m facing is that the DMA2D transfer complete callback is neve...
Hello.I've been struggling for several weeks to fix an issue when sending data over MQTT using LwIP on an STM32F407 microcontroller.For periodic message publishing, I'm using the following code:void MqttPublishTask(void const * argument) { err_t err...
Hi All ,Am imported a example project in stm32cube and i tried to build am getting error as Description Resource Path Location Typenon constant or forward reference address expression for section .ARM.extab LTDC_Paint line 90, external location: c:\...
Hello everyone,I ran into a problem. First of all, I have two tablets: one with a bootloader and another without it. Tablet without bootloader works fine so its something bad in bootloader. I’m trying to plug in and unplug the power supply, and somet...
Hi,I'm using an STM32H7 board with a LAN8742 PHY, configured via STM32CubeMX.LwIP is initialized without RTOS, and Ethernet is in RMII mode. The main goal of this project is to receive data over UART and forward it via Ethernet.I want the STM32 board...
