Are there any plans to support the STM32MP157F-DK2 board in mainline (vanilla) U-Boot?It's supported in the ST fork from U-Boot, but with an older version from U-Boot from the year 2020.Could also ask this in the U-Boot mailing list.
I am using a KSZ9021GN PHY in MII mode. Due to supply chain issues we had to resort to this PHY. (Cube MX says I can't use GMII mode). I am experiencing this apparently common issue: [ 15.650981] dwmac4_dma_reset err [ 15.652849] stm32-dwmac 580...
Is micro python an option?
I have to design a system, where a STM32MP157, with its embedded Cortex M4, communicate with other clients over a high-speed serial connection. There should be a 10 : 1 serializer for the MOSI line, and a 1 : 10 deserializer for the MISO line (from t...
We want to use FFmpeg for video processing (encoding, decoding, scaling, format convertion, etc) on a STM32MP157C based custom board. I understand STM32MP157C has a display controller and a Vivante GPU that supports OpenGL-ES and OpenVG to accelerate...
Currently I am trying to set up the emmc boot on a stm32mp157. I have mirrored the partitions of a working SD card to the emmc with:sgdisk -e /dev/mmcblk1 sgdisk -R=/dev/mmcblk2 /dev/mmcblk1 sgdisk -G /dev/mmcblk2 dd if=/dev/mmcblk1p1 of=/dev/mmcbl...
Hi everyone,I am using stm32mp157f-dk2 with openSTLinux-5.4-dunfell-eglf distribution.I would like to configure my device tree using cubeMX.The generated dts file seems OK to me. However, how can I tell yocto to use my newly generated device tree?...
I've just watched a few tutorials on ADC, and I've enabled IN1 on ADC1 which seems to map to the connector labeled A3 as per this doc.I then added the following to my main.c within the CM4 project.uint32_t raw = 0; char msg[100]; HAL_ADC_Start(&hadc1...
I have a 3rd party SOM (seeed studio Odyssey). When I edit the .dts file in the tf-a-stm32mp1/fdts directory and add: &pwr_regulators { system_suspend_supported_soc_modes = < STM32_PM_CSLEEP_RUN STM32_PM_CSTOP_...
Hi all,I am trying to interface SN65DSI83 with STM32MP1.Below is my device tree:<dc{ status = "okay"; /* USER CODE BEGIN ltdc */ port { #address-cells = <1>; #size-cells = <0>; ltdc_ep0_out: endpoint@0 { reg = <0>; remot...
