Hi All,I am choose the STM32U585VIT6 MPU to design our customized board. Firstly I design a simple basic connection to program it and only blink the LED for confirmation our initially circuit. Also I following the AN5373 document.When I flash the co...
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 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 ...
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 ...
my code only made changes the io, no rtos, no interrupt, but it cost over 1 us. the picture is that io sta. and clock
Please keep the title short!Original title:"is there possibility we can auto mount a usb when connected to usb host and how to build the udev-extraconf package for my stm32mp157f-dk2"how to build this please give the steps to build for my stm32mp15...
Can I only modify the ttt-ip-init-systemd.sh script if I need to change and persist the IP address while using the STM32MP switch mode?
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...
Hi everyone,I'm currently working on the PCIe part of the STM32MP25 and would like to ask if there's anything wrong with my configuration. I’ve followed the official documentation provided by ST.Here are the documents I’ve referenced:PCIe device tree...
