I am currently using stm32f407 with FreeRTOS as operating system in MDK IDE. Recently, When I added a new function ( The new function is ospf routing algorithm, and it is very complex and involves many files ) to my project, I began to encounter hard...
This is mostly a post to help people who try to google this later since I couldn't find anything. If you look at AN2606 table 197, it lists the minimum startup time for the bootloader on a bunch of different STM32 microcontrollers. For some reason, j...
Recently, I have been working on a project that intends to utilize the v9.x bootloader on an STM32L471VGT6 through the SPI 2 port. When utilizing the write memory command, I would find that the STM32L4 would occasionally have 0xFFFFFFFFFFFFFFFF writt...
Hello,I am currently working on sensorless PI control for a BLDC motor, and I am using the STM32F303ZE MCU for this project.In sensorless BLDC motor control, the motor must transition to the next commutation step 30 electrical degrees after the zero-...
I am working on a STM32H723 microcontroller and I am trying to use and SPI communication in mixed mode, i.e. normal and DMA.The reason I need this is because I have a third party software stack for a device that is set up in a certain way, and it cyc...
Hi,I am using STM32N6570-DK kit. In my application I need ~3.5MB of RAM but if I allocate more than 256KB of RAM I get the error "region `RAM' overflowed by xxxx bytes". I got the same results as well when I imported "UART_HyperTerminal_IT" example ...
I am working on a prototype board using the STM32H725VGT, based on an existing custom board where LWIP/RTOS Ethernet is already working. Since I have a preference to keep the same MCU for the next design, I am evaluating its ability to support an 8-...
Im building some phase shifting control sensing for a Dual Active Bridge.Im using TIMA and TIMD (shown in pictures) in retrigerable single mode, both signals are triggered by sepparate CR from the master timer. https://community.st.com/t5/stm32-mcus-...
Hi,I am encountering a hard fault on my STM32F407ZG when using snprintf(). We are using FreeRTOS for the development.The system resets due to a precise data access violation (PRECISERR).Below is the fault status: HFSR: 0x40000000 BFAR: 0x38383600...
Greetings!I have a board with STM32H747XI and SN65DSI84-Q1 as a converter from DSI to LVDS.The issue is that I can not get video output from MCU to 2ch LVDS panel 1920x720 with any configuration I'm trying. The main issue is that I'm getting HAL_DSI_...
