I have a STM32L4R5 STM32CubeIde project using FreeRTOS.I have implemented _read(), _write() etc. to use UART for I/O.printf() is working fine.I can read characters from stdin using read(0, &mychar, 1) but getchar() does not work.I've traced through g...
1. When using 16M external SDRAM as emwin cache, (1366*768*3*2) is used as LTDC display space, (8192*1024) is allocated to GUI memory as GUI_NUMBYTES. When double buffering is turned on (RGB565 color format), the displayed image will be stuck at a fi...
Hello, bit of a MCU newby here - any help would be appreciated.As the title suggests I'm trying to get VCP working with HAL on the arduino portenta h7 which uses a STM32H747XI. I'm on Windows 10, the board appears as "USB Root Hub (USB 3.0)" in devic...
Hi All,I practice an HID USB project at windows 10 with NUCLEO-F303ZE. And I initiated a project by STM32CUBEIDE and STM32CUBE. I alsp can get enumeration of connecting procedure so far so good. My project has a request which needs to response strin...
Data is lost when reading NAND flash data with "HAL_NAND_Read_Page".It is caused by the interrupt of SysTick timer.We have confirmed that "STM32F429NIH6" does not cause data loss due to the interrupt of the SysTick timer.Why does "STM32F723ZET6" have...
Hi, I am working on CVEs and open anomalies analysis for STM32 software to see if there are any recent fixes (in past 1-2 years) which may impact our software and we need to include them.I am going through the questions asked in community forum. But ...
Hello Dear Experts,I have strange behavior on my STM3210 board.I flash my binary using STLink and it works well.Then I toggle BOOT0 pin in order to use the standard bootloader in the system memory and I reset the system.The bootloader starts and list...
Hi All, I followed the updated ST tutorial on Youtube for setting up USB-PD (https://www.youtube.com/watch?v=-vsJhNIaHxE) and I can't seem to actually get it to show up on the STM32CubeMonitor-UCPD app after following as closely as I could. I am desi...
Every period of time i send ~33bytes through USB CDC, if suddenly USB cable disconnected and reconnect i get 16 bytes of the last message loaded, and then continue to get new messages.How can i detect disconnection and were these 16 bytes located?
Hi,I am currently working on a resource-hungry project which requires a lot of memory for storing various buffers and RTOS threads stacks and objects. We are using the STM32L476 controller with Keil uVersion 5.34 IDE and Keil RTX5 as RTOS (CMSISv2) f...
