Hello,Is there any STM processors that can run OpenSTLinux and support 3 lane MIPI DSI? I was planning on using STM32MP1 series but it only supports 2 lanes. Thanks!
I am confused by the different packages ,Starter, Distribution and Developer.Which one do I need to install/setup/build to have as the end result a "minimal" cli/shell based SD card image with support for all hardware on the DK2 board ? a "clean" ro...
Hello All,I make an introduction, it is my first experience in the stm32 world, but I've been working with Linux embedded, MPUs MCUs etc.. for several years.In this days I'm starting to understand and try the M4 core in DK2 evk, following the wiki i'...

Hi,I have to change the CPOL and CPHA of SPI, because I'm communicating with different SPI-Devices. This worked fine on a Nucleo-Board with a Cortex M7.On the Cortex M4 of the STM32MP157-DK2 it ends up in HAL-Timeout :(After some time I found a solut...

I'm writing an Yocto recipe to integrate Kivy (kivy.org) into the st-image-weston image for STM32MP157C-DK2. Main questions:1) Is there recommended GUI framework for openSTLinux, beside QT (license issues).2) Did someone ever add Kivy successfully to...
