Hello!I am trying to program a bootloader so that it loads directly my application (.bin) through the USB in the electronic card STM32F469-DISCO but it does not work for me. I would like to know if there is a generic bootloader that I can download to...
Hello,I'm using the STM32F767ZI and I'm using the FatFS feature with USB host communication. I created a project based on the example provided by STM32 CubeMX.The program works. I can read in one file and write in another. My problem happens when I w...
Dear friends,I am trying to read data from DS3231 RTC using SPI3 peripheral of STM32407VGt6 MCU.At first I used the latest version of HAL drivers and Cube and easily could read/wrtie the DS3231 RTC module. But now I need to use Standard Peripheral li...
I am using an STM32L010k8 device, every second word write to Flash using the HAL driver function HAL_FLASH_Program() generates a write protection fault (WRPERR bit in FLASH_SR). If I retry the write to the same address the error is not presentIs this...
