Hi ST,We have developed a custom board based on the STM32MP257F-DK design, with the primary difference being the use of the STM32MP255DAK3 processor in place of the STM32MP257F. All other components and configurations—such as RAM, eMMC, and SD card i...
Hi,We are using a display with the Sitronix ST7701S IC. We received the initialization parameters from the vendor and updated our display driver accordingly. After these changes, the psplash screen appears correctly when the driver loads from kernel....
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&...
Hi everyone,I have the STM32MP257F-DK development kit and I'm interested in flashing or building Android OS for it. So far, I've found some resources and guides for the STM32MP257F-EV1, but nothing specifically for the DK variant.From what I understa...
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...
