Dear ST community,I am currently trying to install an 8bit 8080 LCD , and i figured out that it needs FMC $ to be set up in devicetree in order to interface with it using DRM in Linux. i have the following device tree pinctrl nodes setup fmc_pins_m...
I am bitbaking the core-image-minimal image, for a plain yocto poky distribution (Kirkstone), using stm32mp1 as my machine, and I am trying to figure out how the various st partition images are included in the build process. That is, how and where ar...

I have an STM32MP157D-DK1 development board and have built a buildroot image using the bootlin buildroot-external-st (st_stm32mp157d_dk1_demo_defconfig) external build tree. I have an Acubrite 12" 1080p touchscreen monitor that I am trying to get wor...
i have been trying to use the LTDC peripheral on the Linux kernel to use it on the ILI9340 / ILI9340 in 8 bit mode.i use this in the device tree: <dc { status = "okay"; port { #address-cells = <1>; #size-cells = <0>; ltdc_ep1_out: endpoi...

Having doing a workshop regarding OpenST linux boot customisation (https://www.youtube.com/watch?v=hqGA5Krk0mU), I stumbled on a problem with a mass storage mount. Doing "ums 0 mmc 0" in uboot gives me partitions within an sdcard but only to see them...
Hello, I am using the STM32MP157F-DK2 board, I also developed a carrier board in order to use external peripherals. I am using a 5V external power supply and I supply it through pin headers CN2 expansion, since I don't want to use the USB type C conn...
Hi Im using a STM32MP157-DK2 with a OpenSTlinux. I load my .elf file of for the M4 to /lib/firmware/ and starts it by chaning the state to start in remoteproc. The problem I have is that remoteproc seems to not run the code from the beginning of the ...
Hi there,I have a custom board based on STM32MP157F, with USB2 connected to STM32CubeProgrammer for flashing the eMMC. No USB-ID, no USB-VBUS connected.The STM32CubeProgrammer downloads the FSBL and U-Boot, but the software does not reconnect as "USB...
