Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
I was handed an existing build that creates an SD card image for STM32MP1 and, while the partition allocated for the root filesystem is a gargantuan 9G, it's clear the filesystem created inside it is much smaller -- around 512M -- and I'm already at ...
Hi,I have few custom boards with STM32MP257 mostly running PTP related tasks. Once in a while (once in a few days of continuous run) I have noticed the following error in the dmesg (as it seems UART related - I have 4 UARTs enabled in the DT, while 3...
Hello,I am currently working with the STM32MP157-DK2 platform and would like to integrate OpenPLC into my Yocto-based Linux distribution.I would like to inquire whether STMicroelectronics provides any existing Yocto layer or recipe for OpenPLC. If no...
Hi there, I found several issues in the STM32CubeMP2 CMSIS headers as follows:1. Missing opening parenthesis in bitmask macrosIn stm32mp21*xx.h, _Msk macro definitions were missing the opening parenthesis, leaving a dangling closing parenthesis with ...
Hi, I am working on STM32MP257F-EV1 Evaluation Board. I want to use shared memory (like DDR) between M33 and A35 cores. M33 should write data samples collected form peripherals in shared memory array and A35 should read this memory array to process i...
Hi everyone,I’m currently working on a camera preview pipeline on the STM32MP257F-DK using the Sony IMX335 (MIPI CSI-2) sensor.One important point is that STM32MP2 uses a media-controller-based camera architecture (DCMIPP + CSI subdevices). Because ...
Hello,I am facing a kernel crash (Oops) on an STM32MP2 platform while using UART with DMA. The issue occurs during runtime power management resume.EnvironmentPlatform: STM32MP2 (custom board)Kernel: 6.6.78 (OpenSTLinux - Yocto Scarthgap)UART driver: ...
I want to do hands on interfacing of all interfaces available with STM32MP157C-DK2.Can you suggest resources on how can I do all interfacings on STM32MP157C-DK2.
Hello,I'm a migrating from openSTLinux ecosystem 5 to 6 on an existing product of ours (with a stm32mp157) and we are really focused on power consumption efficiency. The main difference between our first version and the second is that we first had TF...
Hello. I have a custom stm32mp135f board with emmc1(SDMMC2) and about to launch linux.(Minimized version of 135f-dk, no-sdcard, no-ethernet)I flashed the target with the CubeProgrammer normally.When the kernel loads userfs there says 'root '/dev/dis...
