My board (STM32MP135D) useTIM2 to count the external clock.PE15 cannot work properly, but PA15 works normally. // ok tim2_pins_mx: tim2_mx-0 { pins { pinmux = <STM32_PINMUX('A', 15, AF1)>; /* TIM2_ETR */ }; }; // not work tim2_pins_mx: tim...
Title shortened from "How do I know the pinout of the STM32MP25 chip that the LVDS interface on the STM32MP257F-DK development board connects to?"Please see: How to write your question to maximize your chances to find a solution.When we added an LCD ...
We are developing the STM32MP257F-DK development board. We searched the development documents on the official website of ST and found the development documents of STM32MP257F-DK (https://wiki.stmicroelectronics.cn/stm32mpu/wiki/STM32MPU_Developer_Pac...
We are changing the kernel configuration. According to the document (https://wiki.stmicroelectronics.cn/stm32mpu/wiki/Menuconfig_or_how_to_configure_kernel#Menuconfig_and_Developer_Package), when we reach the step of make ARCH=arm64 Image.gz LOADADDR...
Hello.I am designing a circuit with stm32mp157f.I'm looking for eMMC when choosing memory because 4Gbit slc nand flash is too expensive.In the datasheet, I read in the data sheet that stm32 supports emmc.The question is as follows.Is it correct that ...

Hi,based on the information I get from the schematic of the STM32MP257-DK development board, I'm trying to develop a small embedded board that comes with much less interfaces and therefore is much smaller than this development kit board. Namely it wi...
The kernel is complaining that the specified root partition (identified by the PARTUUID) is not found or isn’t valid, and this is happening at the kernel level rather than in U‑Boot. In other words, U‑Boot is simply passing the kernel command line (w...
So first of all I'm working on creating a yocto image for this board.https://www.seeedstudio.com/Odyssey-MP135D-eMMC-p-5728.htmlMy end goal is to create a meta-layer with an easy to follow yocto quick start guide for this board similar to the one Se...
Hello guys,As per the subject, where can i find a guide about starting new OPTEE port? Unfortunately i didn't find anything descriptive enough in the WIKI. Being stm32mp151c additionally complicates the matter as all supported platforms are '157x. ...
