I have FreeRTOS set up on an STM32F107 performing several tasks of different priority in "parallell". There is one task of IDLE priority that blinks an LED and one task of Normal priority that receives communication over CAN (triggered by external i...
For DMA, allocating the buffer to the right memory segment,I am already allocating the buffer in to D2 (0x30000000), which I think should be right, and I haven't enabled the cache yet, for remaining all nonvolatile memory allocated in section D1 (0x2...
Hi.If power is applied while USB is plugged in, it is possible to read and write data with USB MSC and Fatfs.I am looking for a way for USB to be detected when I plug in USB while STM32 is running.Even if I look for a way, I found only STM32 device....
Hi all, On an STM32F746-Disco I've succesfully tested DFU using DfuSe demo (ie sending a .dfu file from a PC to the board using the USB as a serial port) and the USB Host MSC... I wonder if it's possible create a bootloader that will read a dfu fil...
I see in AN2606 in the section for the L4XXX and DFU bootloader the use of PA11 and PA12, but I don't know what I'm supposed to do with these to achieve DFU mode. I have created a port of micropython that has a firmware.dfu file for loading; however...
Hello,When using external NOR is it reasonable to configure its memory addresses as cacheable or should it always be configured as NON-cacheable?If it is cacheable it means that when executing a programming nor command, it is not yet written into dev...
I'm trying to jump to the bootloader in system memory in order to update my firmware via USART1. See attached code based on https://stm32f4-discovery.net/2017/04/tutorial-jump-system-memory-software-stm32/. When I execute the attached function the s...
Hi, I'm new to CAN communication and trying to up the CAN(normal mode) between two identical custom boards having stm32f072 controllers. Code generated using CubeMX (STM32Cube_FW_F0_V1.9.0) drivers.I have given the setup diagram. TJA1050 RS pin is gr...
Hello,I'm testing to flash a new firmware using an ESP32 on an STM32F103xC, using the application note AN3155. There seems to be an error in the computation of the checksum that must be included in all messages. The documentation states that : 1. ...
I would like to report a bug in HAL TSC library for the stm32L0 series of microcontrollers.The bug is in the stm32l0xx_hal_tsc.h header file in the __HAL_TSC_GET_GROUP_STATUS macro.This is the current version of the macro (buggy version):#define __H...
