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...
We have a custom design based on STMP32MP133A na an spi NAND. On paper, using the u-boot diagnostic commands, everything is working correctly.NOTICE: CPU: STM32MP133A Rev.Y NOTICE: Model: Zehnder CCPRO A1R Board INFO: PMIC version = 0x21 INFO: ...
Heyho,I just checked the MCU selector in CubeMX (6.13), and to my surprise I didn't find any MPU supporting the following:gigabit ethernet (RGMII)FDCAN2 SAIs (I need at least 4 standard I2S/PCM "stereo" channels)The MP series don't have FDCAN.Then I ...
We're in the process of upgrading our custom board software to STM32MPU-Ecosystem-v6.0.0, using Buildroot as our build system (buildroot-external-st st/2024.02.9).Our device uses standby mode for low-power operation, and we rely on RTC wakeup and but...
I need a partition as a backup partition for the root file system.How can I add a new partition in stm32mp2?
