Hi there.As usual, I'm there with a new issue... :grinning_face_with_sweat:Developing a custom Bootloader, I'm trying to disable both Instruction and Data chaches.As I read on the ST AN4839, before deactivating the DCache, I would also Clean it.No pr...
Today I started to implement DMA for the SDMMC peripheral, and it worked for the most part, but when I got around to doing some sector writes, I started to get CRC-16 mismatches. This was a relatively simple fix, as I was enabling the Data Path State...
In the ethernetif.c file,typedef enum{RX_ALLOC_OK = 0x00,RX_ALLOC_ERROR = 0x01} RxAllocStatusTypeDef; // Here, RxAllocStatusTypeDef type is not used.It says that RxAllocStatusTypeDef is not used, which violates misra-c:2012 2.3.Inferentially, this wo...
Hello,I'm having some issue going from my user code running azure RTOS to the bootloader. I'm using a STM32U599The code I'm using is the following, you can find online: void JumpToBootloader(void){uint32_t i=0;void (*SysMemBootJump)(void);/* Disable ...
I'm using an STM32 H7 and CubeIDE, As the title states, When placing a breakpoint at HAL_UART_TxHalfCpltCallback, it is triggered.But when placing it at HAL_UART_TxCpltCallback it is never triggered, it used to work, but I don't know where it went wr...
Today I decided to improve the performance of my USB driver by transferring multiple IN packets at a time, instead of one at a time. This in theory would be relatively easy, as I can just configure the IN endpoint's TX-FIFO to have a larger allocatio...
Hello I am working on the Free RTOS code that I am trying to send the data on the server using Free RTOS but I am not able to send data on the server I am using some dummy data and GPS for location +STM32F411ceu6a+EC200U GNSS. But my RTOS task is not...
Hi, i'm using my Nucleo STM32F401RE as a HID Device for a MIDI Keyboard projectI have configured the following:Connectivity --> USB_OTG_FS --> Device OnlyMiddleware --> USB_DEVICE --> Human Interface DeviceI followed a video tutorial to configure the...
Hello everyoneI do not understand how to use the STACK_SMBUS_ExecuteCommand callback function provided by the SMBUS stack (See picture below). The function is called either in receiving data or transmitting data (from the device point of view). Due t...
I can transmit data in this code, but I cannot receive data with an interrupt. Can you help me?Code:#include "main.h"#include "kibar_nextion.h"#include <string.h> UART_HandleTypeDef huart4;UART_HandleTypeDef huart3; uint8_t main_buffer[13];uint8_t pu...
