Hello everyone,i'm working on a custom SOC based on ST32MP135 and LAN8710 ethernet phy chip.When the HAL_ETH_Init() code runs and sends the module reset by setting the ETH_DMAMR_SWR bit, the loop exits with the HAL_ETH_ERROR_TIMEOUT.The current inter...
Using board based on stm32mp135f MPU, my goal is to configure a GPIO pin (let's say PD0, already freed from using with CAN) as a simple GPIO Output, active-high, with pull-up.I read following ST Wiki entires:- Overview of GPIO pins,- GPIOLib overview...
I'm currently working with an IMX219 camera sensor connected to the STM32MP257-EV1 board. The camera is successfully streaming, and the pipeline appears correctly configured through media-ctl. However, I’m unable to use the dcmipp-isp-ctrl tool at ru...
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 ...
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.
