Hello,Sorry for a long post this needs some context.I've been configuring and testing OP-TEE from the following guide:https://wiki.st.com/stm32mpu/wiki/How_to_configure_OP-TEEI'm using the STMicro fork of optee_os (tag 3.16.0-stm32mp-r2), and the OP-...
Hi, I use boot1 pin as gpio key function. The boot1 is PI5, and I configure it in kernel dts code. When the system boot up, the input event0 device is shows, but I use hexdump can not get any key code data. Currently, my board is boot from sdcard. gp...
1. Can the display interface be driven by the M4 core while the A7 core is powered down?1a. Can the AXI interconnect peripherals be driven by the M4 while the A7 cores are powered down?2. Display controller - is there any loss in performance if using...
Hi all,I updated my project from Morty (2.2) to Kirkstone (4.1). After doing the required fixes/updates on the recipes, I have problems booting the FSBL. I am using the Cube Programmer to flash the image. Below is the log:STM32CubeProgrammer API v2.1...
Hi ST Community, We have planned to use STM32MP131A MPU in one of our custom designs with low power consumption as the main target. We have come across STM32 CubeMX v6.8.1 for estimating the individual current consumption in various modes and whi...
I am trying to use the UART4 TX: H13 and RX: H14 pins for the tty console access.The TX from the MPU works fine as I can see the kernel boot logs, but cannot access the kernel command line. No prompt shows up on hitting ENTER.Here are my stm32mp15-pi...
Hello.I'm trying to make simple openAMP with STM32MX(with STM32cubeIDE, .ioc file).The code is simiar to OpenAMP_TTY_echo. I include virt_uart.h and use VIRT_UART_Init code inside main function and others like making RxCpltCallback and registor callb...

Hi I have problems with our custom board bringing up the VREFBUF. I eddited the devicetree as follows (also in U-Boot).&vrefbuf{ status = "okay"; compatible = "st,stm32-vrefbuf"; reg = <0x50025000 0x8>; regulator-min-microvolt = <2500000>; regul...
I am trying to creating u-boot files for self definded project.Unfortunately i get the error during individual building (see https://wiki.st.com/stm32mpu/wiki/STM32MP1_Developer_Package#Installing_the_OpenSTLinux_BSP_packages:(Device Tree Source (arc...
