Hi!I am using STM32MP157C-DK2 and i want to start the coprocessor from bootloader (I have readed the wiki page). First, I have done it manually and everithing works fine:I have changed kernel m4_rproc:&m4_rproc{ /*Restriction: "memory-region" proper...
I'm having trouble getting TF-A to start from USB DFU using the STM32Programmer CLI. Here's what I get:$ ./xpro_uboot_prgm.sh ------------------------------------------------------------------- STM32CubeProgrammer v2.11....
Hi all!!Follow the wiki page, I added support to kernel FIT image in my Yocto distro for the board stm32mp157c-dk2 based on openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23.Just I added the option: MACHINE_FEATURES += "fit" and I selected BOOTSCHEME_LA...
Hi,We are using stm32mp157a-dk1 board. In this when we boot Cortex-M4 code with rproc commands in uboot, cortex-M4 is running.We are using stm32mp157aaa3 processor in my custom board. When we are trying to boot Cortex-M4 in Uboot with rproc commands....
Hi, community.I am trying the SD UHS-I mode on your evaluation board(STM32MP157F-EV1), but it does not work.Q1. Does HAL support UHS-I?Q2. Is it necessary to enable SDMMC_CLKCR_SELCLKRX_1? (when using STM32MP157F-EV1 board)Q3. What is the reason wh...
We need to enable/disable pwr_sw1 and pwr_sw1 preferably via sysfs:vdd_usb_sw: pwr_sw1 { regulator-name = "vdd_usb_sw"; }; vdd_sd_sw: pwr_sw2 { regulator-name = "vdd_sd_sw"; regulator-always-on; regulator-boot-on; regulator-acti...
Hi everyone,I'm trying to optimize the boot time of tf-a with Yocto but don't find much information on the web. Currently tf-a takes about 1s from the point in which it is read from NOR to the point it loads UBoot from same NOR. I optimized the Linux...
Hi! I am using STM32MP157C-DK2 board to create an application on the screen (using GTK library). My idea is to create a window with the following image inside:Created code:#include <gtk/gtk.h> int main(int argc, char **argv) { GtkWidget *window...
Hello,I am using the stm32mp157c-ev1 board. I used this guide from digi-key to install debian on it (Debian: Getting Started with the STM32MP157), except in the parts where it says stm32mp157c-dk2 i replaced that with the appropriate '-ev1' suffix. I...
Hi,We are using stm32mp157a processor in our custom board. In Stm32mp157a-Dk1 board i am able to run Cortex-M4 code in uboot using rproc commands Cortex-M4 is working fine. Where as in my custom board I followed the same sequence but Cortex-M4 is not...
