Hi I have a board based on a STM32MP135F. I can see that CLK signal of my sdcard (SDMMC1) very look like a 50 MHz sinusoidal instead of a clock. I have tested with and without my 22 Ohm resistor on this line and I am now looking into the device-tree/...
I created a layer using bitbake-layers create-layer --priority 7 ../layers/meta-st/meta-my-custo-layer and created mkdir recipes-graphics/wayland/weston-init/ and created folder called files and append file weston-init_%.bbappend and in files i add...
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...
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 ...
