Hi erveryone,I want to implement A/B partitioning functionality, not for updates, but to enable switching to an alternative ROOTFS partition if U-Boot fails to start the kernel. For example, if partition A fails to boot three times, switch to partit...
how to add meta qt layers into our OpenSTlinux distribution package. please do step by step
My MP157DAC board encountered some problems using SDKv5.0, u-boot could not be started correctly when using usb burning, it seems to be related to DDR, but I can not find the reason, the community does not have similar problems, hope to get some help...
Hi everyone,I'm working on a custom board based on STM32MP157F-DK2. I am running Yocto 5.0.3 (scarthgap) with trusted boot (not signed).I could build the Zephyr (3.7.0) rpmsg sample that worked out of the box:https://docs.zephyrproject.org/latest/sam...
Hello We are Working on a custom board with STM32MP157AAA3 processor.We are using Buildroot(V2023.08.2) for checking USB 2nd Port in which the PHY port 2 is configured as host controller using UTMI . we referred the below link to configure the dts :...
Hi I am using the discovery kit (STM32MP157F-dk2), i check the manual and i did not get the Actual pin of the CANFD , so please let me know the pin of the CANFD or other-wise could you please provide me the example how to read the CANFD value from th...
Hi everyone i download the Distribution package for ##STM32MP1F-DK2 and i made some changes on kernel like in device tree, my colleague is doing work-from-home job, So my colleague wanted to see the changes own there laptop and something want to chan...
Hi Every One i am facing the issue to find the pins of PWM in the (STM32mp157f-dk2 ), i configured the PWM channel in device tree and pwm channel is visible in /sys/class/pemchip0/pwm , so i need to collect the input from the pins but which pin is c...
Hello,I am wondering what could be the best way to write a device tree that sets the STM32MP1 as SAI SLAVE with a CODEC also running as SAI slave. The HW design I am studying has the following specs:1) STM32MP1 with ALSA and one SAI interface.2) A co...
I tried to replace the uImage and .dtb file inside the starter package.First I copied over the kernel and .dtb file.sudo mount -o loop st-image-bootfs-openstlinux-weston-stm32mp1.ext4 /mnt/bootfs sudo cp ../linux-6.1.82/build/arch/arm/boot/uImage /m...
