Hello.I am developing a UART bootloader. Currently developing it on the Nucleo H7S3L8 that sports the STM32H7S3L8 microcontroller, 65K flash, ~450K something RAM.I have implemented the ol' JumpToApplication pattern that can be found all over the inte...
Hi Community,I recently received a new STM32H747I-DISCO board, but I’m encountering some issues. When I plug in the CN2 USB, no display shows up. I've tried reprogramming it using the STM32H747I-DISCO compiled demo binary but received Error: failed t...
MCU: STM32F411CEU6 So, I am having a weird issue. I created a bootloader for my application to accommodate OTA updates. Bootloader makes decision when it has new firmware inside external flash(the application code tells it), then bootloader loads tha...
Dear Community.Short Rant (sorry, need to let off some steam):I wonder, why there is not more questions on I2C-slave here. What started as a "cool, I will use the HAL, greater people than me have written these libs" has now turned out to be my worst ...
Complete noob in both uCs and C trying to understand how to actually read the documentation and where to look for the answers.I am using CubeMX to generate a majority of my code and using HAL.I have succesfully got DMA transfer to update different ti...
