Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
Hello,coming from OpenSTLinux 4.2 (mickledore) we are in the process of migrating to OpenSTLinux 6.2 (scarthgap).The process of how multiple partitions (bootfs, vendorfs, userfs) are "split out" of the rootfs appears to have changed considerably.Afte...
Hi,We are building Linux for STM32MP157D using Buildroot, and we are experiencing an issue where the boot process sometimes does not proceed from BL2 to OP-TEE, and sometimes OP-TEE does not proceed to U-Boot.Occasionally, the kernel does boot succes...
Hello STM Team,I have been trying to get the GC2145 to work on the DK but no matter what i do i only get /dev/video0 but never /dev/media0I use Buildroot with the Linux kernel on ST's Github. I have followed this guide here: https://wiki.st.com/stm32...
Hi everybody,For a project, we need to start the STM32MP257F in the M33 flavor, in order to perform some basic functions (GPIO, I2C, UART) in the lowest power mode possible (DDR unpowered, A35 in low power mode — i.e., no remoteproc nor Linux). The g...
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 ...
