Hi,The bootfs firmware compiled from the Yocto environment I am using is a symbolic link. Every time the STM32CubeProgrammer software downloads this firmware, it exits directly.I am certain that the firmware itself is fine. If I directly modify the b...
Hi,During the integration of FreeRTOS using STM32CubeMX on the STM32MP157F-DK2 platform, the initial compilation fails. In my experience with other ST microcontrollers, the initial build after adding FreeRTOS generally completes successfully without ...
Hello, I want to boot Linux straight from the FSBL, avoiding SP-Min and U-Boot. Is there any configuration or information on how to do this? Thank you. I got a STM32MP157F-EV1 board, I wouldn't mind using TF-A or U_Boot SPL, I am also looking at ...
Hi Community,I am working with an STM32MP257 interfaced with 16 bit DDR4 of 2 number (16 bit * 2 = 32 bit = 1 word). I would like to clarify whether the swizzle bit register values actually affect the DQ pin bit-swapping in hardware.If they do, I ...
Dear ST Developer Support,How to enable MIPI DSI panel on STM32MP257F-EV1?Does it have any user guide for reference?I only found dsi to hdmi board on device tree.I urgently need your help! Thanks.
Hi ST Team,1. I have followed the steps mentioned in link to build the yocto for stm32mp25-eval machine and can successfully flash the eMMC tsv file .2. Started to explore on creating a custom machine configuration file and custom layer in the yocto...
Hello,I have a problem with the configuration of LAN8720A with STM32MP151. My log looks good, but I have a problem when I plug in the wire to the RJ45 port, I get 'Link is down', and vice versa when I plug it out, 'Link is up'.Here is part of my DTS&...
I am trying to debug a basic project on a STM32MP257F-DK board, and am running into an issue. This is the text of the error I get every time I debug: 'Launching <project>_CM33 Debug' has encountered a problem.Error in final launch sequence:Failed pre...
I am trying to configure a USB-C connector on a peripheral device to detect VBUS via GPIO (PH9). I have tried several iterations using the following device tree documentation.- 3.3.1. DT configuration example as high speed OTG, with micro-B connector...
We actually experience the problem that the address of the SysTick_Handler is read incorrectly from the memory address of the SysTick ISR in the memory. This leads to a memory management error when the system counter reaches 0 and the SysTick interru...
