I'm using an STM43H755 (on a NUCLEO-H755ZI-Q) and I need to send pixels to an external LCD module (320x240, 8bit MCU bus on ILI9341 controller, 3.3V compatible).I've used plenty of single core MCUs like F0, F4, F7 and others from ST in the past but I...
Hi!I am writing a bootloader for an STM32H7S3L8, that received the application binary over UART and places it into flash, specifically on address 0x08008000, and I am getting hard faults when jumping to the address.If I "install" the application AND ...
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...
Hi all, Am using STM32L010R8T6 device how to retain gpio state when jumping from main application to bootloader section. i want to retain one gpio pin state from main application to bootloader. How to achieve it. Is there anyway to achieve it. Please...
Hi,I understand this has been discussed before, but can we please get an official explanation of how the dma tail pointer works in the Stm32H7 eth mac ip block? It's extremely difficult to write software to support the eth mac when the docs and examp...
