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...
Hello,What is the best (fastest and reliable) way to program a blank eMMC for mass production? In my custom board, the device will boot from eMMC, no SD card is available. The default pins are shown in the link below. For other data pins is there an...
I can monitor the SAI2 signals directly from the audio codec pins. The MCLK, SCLK, and Fs signals appear correctly based on my configuration but when I connect my oscilloscope to the GPIO header pins (CN2), the lines all appear low even though they a...
I am using stm32mp157c and working initialize mtd nand flash w25n512.i was able to run it on kernel mode. Kernel device tree is;aliases { spinand0 = &qspi; }; ... &qspi { pinctrl-names = "default"; pinctrl-0 = <&quadspi_pins_mx>; num-cs = <0x...
