Hello, In the MCU datasheet, there is a table on page 200: Table 72. Typical dynamic current consumption of peripherals.What is the meaning of the current writing in the peripherals on stop modes, since in this mode, all clocks in the core domain are...
Hello,I am using STM32H750VBT6 to perform microSD card write operations. After a number of writes, the CPU sometimes resets during a write operation. At the same time, the Vcore (1.13V) rail shows a voltage drop. The issue is random, but the higher t...
Dear STM32 users and developers, This new thread is back and is dedicated for our technical developers community to share last STM32 updates, the first part will be products documentation news such as datasheets, Erratas, Applications notes followed...
Hello everyone,I’m working on a control unit board based on the STM32F407VETx (LQFP100) microcontroller. During development I noticed that some pins configured as external interrupts (rising edge) were being triggered more often than expected.To bett...
A new question moved from this thread. In many examples they use the Vref int for the calculation of the temperature. Do I need it for the C0 also or can it be done without?
Hi STM32 community.I'm working on an embedded system which uses a RK3399 CPU (running Linux, functions as a USB host) and a STM32F302CC (Runing FreeRTOS, functions as a USB device). This runs on a custom motherboard. They communicate with each other ...
Hi,I am experiencing a core freeze issue on STM32H7S3L8 MCU, as described below.UPDATE 1: Most probably Data Cache is the main culprit, closing Data Cache in bootloader solves the problem. Application code Enables Data Cache and we have never observe...
This previous thread refershttps://community.st.com/t5/stm32-mcus-products/stm32f4xx-does-going-up-a-package-pin-count-impact-pin-af/td-p/862282The 437 is curiously a very close superset of the 417. Apart from the extra 64k RAM, the only difference i...
Hello, We have developed an image capturing application successfully based on STM32H7xxxx and OV7725 camera. We are now targeting to port the application to target STM32U5xxxx with the same camera. But it looks the DMA doesn't works as expected. T...
Hello everyone,I am currently working on a project using the STM32H755 microcontroller, and I am facing an issue with the program getting stuck in the `Reset_Handler` during debugging. Specifically, the code halts at the instruction `ldr sp, =_estack...
