Hello everyone,We are experiencing an issue with a product that integrates an STM32H562ZG microcontroller.Our development environment consists of IAR Embedded Workbench 9.70.1, with the project configured using CMake.Currently, we are observing unexp...
Bit-banding Alternatives for Modern ARM Cores Background Information: The bit-banding feature available in ARM Cortex-M cores (ARMv7-M architecture including Cortex-M3 and Cortex-M4) provides hardware-level mapping of individual bits within a 1 MB me...
My goal is to establish CAN communication between Riverdi display - RVT50HQSFWA01 and my laptop. After developing a test GUI using TouchGFX 4.26.0, when I added the code patch for CAN communication then I keep on getting various build errors due to c...
Sequent Microsystems designs and sells Automation Systems using Raspberry Pi. All our products use STM processors. We use about 10,000 processors per year in different configurations. Generally we do not have any quality problems, but occasionally we...
I’m working on an STM32H7R7 project using SDMMC1 + FreeRTOS (CMSIS-RTOS v2) + FatFs, all generated with STM32CubeMX.I’m facing an issue where f_mount(opt=0) works, but the system blocks inside f_open() and never returns, so the return value cannot be...
I am working with an STM32F0 device and I want to implement a firmware update mechanism.My current plan is to split the internal flash into three regions:Bootloader: 0x08000000Application Slot 1 (App1): 0x08004000Application Slot 2 (App2): 0x0800800...
Hi,We have STM32N6570-DK and are testing camera input, video encode and write to SD cardWe have not been able to make the "VENC_SDCard_Appli" example work, the SD card just contains zeros.The "VENC_SDCard_ThreadX" example does work however, resulting...
I am working on an STM32N6 hardware design, and have reviewed both development kit reference designs (MB1939/MB1940). Both designs use the same power supply scheme, when using internal SMPS it has 2x 3V3 regulators and 3x 1V8 regulators.I am interest...
Experimenting with STM32F427 and STM32F446 I found out, that the RCC_CR.HSEBYP bit is *not* reset by Software reset. It is reset only by NRST and Power-On reset.While applications where this could lead to problems (i.e. where HSE clock source is chan...
Hello sir/miss , According to the STM32H7 datasheet, the range of the HSE external crystal oscillator is 4M - 48MHz. However, when we used the STM32H7IIT6-EVAL evaluation board and replaced the original 25MHz surface mount passive crystal oscillator ...
