STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
Hello !I am using the I3C interface between a STM32H563ZI and 2 LPS28 sensors. After a ENTDAA process I would like to send a SETGRPA but unfortunately it does not work. It seems the process fails during HAL_I3C_AddDescToFrame() due probably to a wron...
Hello I am using an STM32G491RcT6 processor, when I connect it with ST-link to CubeProgrammer the Write Protection section of the option bytes does not appear, if I connect an STM32G491ReT6 processor it does, Document RM0440 does not seem to me to re...
