Displaying camera stream with qmlglsink crashes in gcoTEXTURE_GetMipMap() from gcnano stack
We want to display a camera stream in a QML application on our STM32MP157C-based board. When we use the default QML widgets, the framerate is too low, under 10 fps.We try to solve the problem by using GStreamer's qmlglsink with GstGLVideoItem: it wo...
How do I build an Android application that can connect to a STM32 Eval board?
I am super new to this and I need guidance. Does anyone have experience with using Android Studio to build an app and then using Bluetooth or WiFi so the app can connect to a STM32 Eval board? Where would be a good place to start? I have found the "S...
STM32MP151 Transmit DMA stopping unexpectedly
I am using UART5 on an STM32MP151 to communicate with an external processor. The Cortex-A7 is running Linux and DMA is in use for both receive and transmit. Hardware flow control is also enabled and the transfer rate is 6 Mbps. Currently we are runni...
Resolved! How to add ModemManager and NetworkManager to the st-image-core?
I have an STM32MP157A-DK1 dev board and I have successfully build and flashed the st-image-core (Distribution-Package) and flashed to sdcard.I want to add ModemManager and NetworkManager to the build. I see that meta-oe layer appears to be included a...

Resolved! Rootfs, read only and st_image_core
Hello ST Teams!Question, again! I'd like to know if the image "st-image-core" or "st-image-weston" are compatible with the "read-only-rootfs" from yocto append? (thud or dunfell) Well I've already tried on the st-image-core and bitbake compilation fa...
Disable meta-qt5 layer (openstlinux-5.4-dunfell-mp1-20-06-24)
Hi, I'm trying to make a headless system using the STM32MP153 and I would like to disable all graphical layers in the standard distribution.I'm using openstlinux-5.4-dunfell-mp1-20-06-24 (ECO V2 I believe)I have made my-own distro layer and was able ...
STM32MP1 How to Modify Partition and Flash Layout for RAUC
I am working with the STM32MP157 creating an SD card image using OpenSTLinux. I would like to use RAUC to perform updates but to do so I need to create a second rootfs partition. One active partition and the other for updates. I couldn't find in the ...
Resolved! Is it possible to trigger a USB DFU boot from a running STM31MP157C-DK2 without physical switching DIPs etc.?
What I want to achieve is starting the DFU ROM bootloader (like on a MCU) from a running Linux (maybe via a dedicated kernel module) or, if this helps, via re-configuring u-boot and doing a software reboot cycle.
