Hi,I've noticed when booting one of our board designs with a STM32MP157C in openstlinux-5.4-dunfell-mp1-20-11-12 with Weston Wayland under the STM32MP157-Ecosystem-v2.1.0 that multiple times when the kernel is loading I'll see the message "stm32-dmam...
Similar question was asked here:https://community.st.com/s/question/0D50X0000AvgWuG/how-to-use-timers2-as-pwmbacklightBut this does not work on v5.4 kernel anymore. So a working example would be nice as pwm-backlight device tree handling is not docum...
Hi,My test kit is STM32MP157C-DK2 and kenerl version is 5.10.10.I tried to monitor falling edge event on PD.1, with command "gpiomon --falling-edge gpiochip3 1". It is faile and and the log in the attachment.Then I disable "hdmi-transmitter@39" in "s...
Hello, is there a way to use a debian linux on STM32MP1 instead of openliunxst? How to deploy xlinux ai as well on debian instead of openstlinux?

Hi everyone,I'm interested how can someone backup rootfs, vendorfs etc and later use that to flash via the STM32CubeProgrammer? Is using the dd good way to do it?Best regards,Nenad
We are using the STM32MP15 ecosystem 2.1.0 and buildroot build flow for a custom board. The custom board uses the FMC peripheral to connect to three FPGAs using an SRAM/PSRAM interface. We have successfully implemented this interface on the CA7 sid...
