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...

Hi all,I have been trying to boot a custom ST32MP15 board, I get through TF-A and U-boot, but boot fails while Starting Kernel.I had some issues with external 24MHz crystal so I am using HSI to provide CPU clocks. On TF-A and U-Boot device trees I wa...

Hello,I am trying to read an analog value of PA4 of the STM32MP157CAC with ADC1 but it does not work.I am using from Emtrion the emSTAMP-Argon as module.I also tried to read the internal temperature sensor instead with ADC2 but that failed as well.I ...
I am making a board using STM32mp151a. I want to write Linux OS to the SD card. However, the command on the web page below only has STM32mp153 and STM32mp157 for the evaluation board. https://wiki.st.com/stm32mpu-ecosystem-v5/wiki/How_to_create_your_...
We are migrating from the Kirkstone eco-system to the Mickledore eco-system. We found that the extlinux.conf file that gets created is identical in the two builds. However, u-boot now forces a menu to the user, even though we have CONFIG_BOOTDELAY=-2...
A particular STM32MP1 based board uses the USB OTG interface configured to the cortex A7. Is there any guidance how to configure the kernel so that it will use the USB device port with a gadget driver, so that the host sees it as keyboard, serial por...
