Hi,I am using a PCM3060 codec connected to a STM32MP135 MPU over I2S1 and I2C, and compiling STM Linux (v6.1) (along with STM's version of TF-A, Optee, and U-Boot) using Buildroot.I had some trouble getting ALSA to output to the codec, it kept giving...
The LPTIM_TypeDef struct that is used throughout many of the HAL header files contains a few RESERVED fields that cover unused address offsets in the peripheral's memory map.The first of these, RESERVED1, is declared as uint16_t. I believe that this ...
Hi, I tried the Hello World application on Cortex-A7, I want to try linking my custom application library in this example. Can I do that?I changed the print_hello function and calling another function from my custom library.I tried linking custom lib...
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...
