Hi,I am new in STM32MP1 MPU Linux and wish to get the guiding to start developing Linux OS app for my board. The first question:I need to switch GPIO pins. Any suggestions where to start for single core MPU STM32MP135. Thanks.
Dear All, I have followed the instruction as per Intro to Embedded Linux Part 2 - Yocto Project.The compilation for layer kirkstone. When i run the command "bitbake core-image-minimal" it give error after 4 hours of work.The error is pasted below./ho...
Hello,we have developed a project in STM32CubeIDE which already works.the the project is generated "Under Root" like this: Now we want to implement the compilation in a yocto layer instead of use .elf directly.we have take into account the extended...
Hi ST experts,I'd like to build a bare metal ARM cortex-A7 driver for my MIPI DSI display module. Because there is no HAL driver for LTDC and DSI host then I decided to build it from scratch. I followed the procedures from the STM32MP RM document to ...
I am making a board using STM32mp151a.I want to make Linux OS for this machine.I refered to the web page below.https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machineHowever, Error happened on bitbake process.Please tell me the cause and cou...
Hello,I'm trying to configure an externall interrupt (for a digital signal) to be handle from the User Space. I have configured the following node in the device tree on the root node:/ {... exti_gpio_node { compatible = "test,button"; ...
We are using STM32MP135-DK and we connect to SPI5 an SD Card Adapter.We modified the device tree as follows to use the mmc-spi-slot driver: &spi5{ pinctrl-names = "default", "sleep"; pinctrl-0 = <&spi5_pins_mx>; pinctrl-1 = <&spi5_sleep_pins...
