Hello,I am struggling with improper color management for our display connected as LTDC. I prompt for drm state with cat /sys/kernel/debug/dri/0/stateI wonder why I get format=RG16 (that is true, we use RGB565 LTDC interface) and color-encoding=ITU-R...
Dear all, we use custom board with STM32MP1 SoC onboard. We use Yocto with OE, STM, Qt and custom layers for building target images. In our device we utilize 7-inch display connected by LVDS with RGB666 wiring. If I load bitmap image from U-boot, a...
Hi, is it possible to know which is the Yocto configuration (manifest release, DISTRO and MACHINE used, other configurations, etc) used to generate the Starter Package of a board?I think it could be a useful information for everyone. In fact I'm in a...
Hi Everyone I am new member of ST device, now I face problem regarding SPI communication on STM32MP157F-DK2 kit.I am using the latest zephyr RTOS version (which primarily supported STM32157C-DK2 kit).Problem:- The Master Out pin does not output the d...
Based on the steps of the ST wiki on the stm32mp257f-dk through a VirtualBox to be able to use Linux and configure the A35, we realized that when performing the last steps of the wiki on the M33 we get connection errors with the board. That is why we...
Hello, I have a problem after cross-compiling retroarch from my PC to an STM32MP135 (ARM32), after launching my ./retroarch -v I see that it will look for a video driver named "ext" root@stm32mp1:/home/emu# ./retroarch -v [INFO] [Config]: Looking fo...
Hi Everyone I face other problem of Counter driver on zephyr for STM32MP157 DK2 kit Here is dts: &timers5 {status = "okay"; counter {compatible = "st,stm32-counter";status = "okay";};}; and prj config: CONFIG_COUNTER=y I face problem: zephyr-sdk-0.17...
Hi,I am trying to write a LIN master for STM32MP135 running a Yocto Linux. Currently, I am struggling with the break signal. According to the LIN specification, it has to be at least 13 (up to 20) bits long. The device I am trying to talk to is using...
Hello,Hello,I'm planning to integrate GPS: GNSS1 and install a web browser on an STM32MP157F-DK2, so I'm looking to add layers.Before adding the layers, I thought it would be a good idea to follow this tutorial:https://wiki.st.com/stm32mpu/index.php?...
Hello, I wonder if it is possible to put a game emulator on an stm32mp135-dk1 under openstlinux yocto, if so how? By loading a new img or in another way?
