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...
Welcome, why for STM32MP157FAA1 at "STM32MP1 Series DDR memory routing guidelines examples" there is no terminating resistors?
we are developing the application by using STM32MP1 processor in bare metal.we are able to wake up Cortex A7-1 from Cortex A7-0 both are working fine. Now we tried to wake up Cortex M4 from Cortex A7-0,But we are unable to wakeup Cortex M4 from Cor...
Using the KMS/DRM driver, how can I change the emulated framebuffer format? I'm using simple-panel and the framebuffer has always only 16-bit color even though the driver explicit sets the format for 24-bit colors (.bus_format = MEDIA_BUS_FMT_RGB888_...
When using DCMI camera capture and at the same time play or record audio, there is bad interference in the camera picture. I'm using Linux and ALSA libraries in a platform based on STM32MP157C. Maybe some DMA problem ? The audio is using SAI as with ...
