Hi everyone,I'm working with the STM32MP157C-DK2 board and trying to reduce the amount of RAM allocated to OP-TEE, but so far I haven't been successful.There are 32MiB DDR dedicated for OP-TEE. 30MiB for TZSRAM and 2MiB for SHMEM.In OP-TEE sources I ...
I am able to use FDCAN1 to communicate on the A7 by adding the following to `STM32MPU-Ecosystem-v6.0.0/Developer-Package/stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06/sources/arm-ostl-linux-gnueabi/linux-stm32mp-6.6.48-stm32mp-r1-r0/linux-6....
Hi STM Team,We are working with a custom board based on the STM32MP157DAC.We are facing a video lag issue when trying to play a video file from Qt application 6.5.3 using media player.Even reducing the frame rate had no effect.But if we use gst-play ...
Hello,I'm using Buildroot environment with the STM32MP257F-DK board. I'm testing GStreamer with a simple pipeline:gst-launch-1.0 videotestsrc ! autovideosinkWhen I first run it there is no problem. The test video shows fine on the HDMI monitor. But w...
I am using a custom board (STM32MP157DAA1) and want to use DSI 1 lane. How do I set it up in uboot or kernel?My screen also has 1 lane.
Hi !I am designing a SOM board (based on MP2 microprocessor) and I'm wondering if I must take into account the die-to-pin lengths on LPDDR4 IC side. Or does the intrisic architecture of LPDDR4 components garantee internal equivalent lengths ? I didn'...
Hello, I'm working on PTP synchronization using the STM32MP257F-DK development board, and I'm encountering an issue with generating a PPS output on a GPIO pin. I'm using Buildroot as the build system, configured with the Bootlin external tree availab...
