Is it possible to control LTDC on STM32MP157 by Cortex M4 co-processor?I have noticed that there is no available HAL driver for LTDC on STM32MP157.Why is it so? Can we use the HAL driver for LTDC intended for STM32H7 processors on STM32MP157?
Trying and failing to toggle LED 7 of the STM32MP157C-DK2 from the STM32. The IOC file indicates that PH7 is configured as GPIO. The mode is Output Push Pull, the GPIO Pull-up/Pull-down state is No pull-up and no-pull-down. The Maximum output speed i...
In manual UM2369 it states the following:"To set up an STM32MP157C-DK2 Discovery kit as the Edge gateway for your Predictive Maintenance Platform,you can either:• Use a pre-configured image by ST; these can be flashed onto an SD card and run on the D...
Hello EveryoneI wanted to connect my STM32MP157-DK2 to laptop (Ubuntu 18.04 through a VM). I followed every step in the bellow article but nothing : https://wiki.st.com/.../STM32MP15_Discovery_kits...According to section 6.2 my MP should connect. The...
Hi Folks,I am trying to build openstlinux-eglfs/st-example-image-qt using yocto/openstlinux distribution (please see details below) for stm32mp157c-dk2 board. After fixing compilation problem with qt3d (scene2d example failed to compile) I was able t...
Hey,As a hardware engineer, I worked for a long time with the M7 controller.For a Specific Algorithm, It seems like I should use a stronger core then the M7 480Mhz, when the purpose is to Calculate in Real-time.one of the options is to use the MP153/...
I want to use remoteproc to load and start firmware on Coretex-M4 from Cortex-A7.I refer to the following Wiki page.https://wiki.st.com/stm32mpu/wiki/Linux_remoteproc_framework_overviewIn above Wiki page, I have tried [4.1.1 Remote processor boot thr...
Using the ST provided altium design files for the STM32MP157A-DK1, I've run the design rule check on the PCB as default which shows about 400 violations. Are the design rules set up correctly for this project or am I doing something incorrectly? I'd ...
Hi, I'm trying to build a Yocto-Linux for an specific STM32MP157 board. I was working with "thud", but now "dunfell" is required, as it is supposed to be long term stable.The system is built after ST's manual:https://wiki.st.com/stm32mpu/wiki/How_to_...
I want to know how to specify the address to load Cortex-M4 firmware when U-Boot or Linux Kernel load the firmware of Cortex-M4 in Retention RAM.And, how to specify the address to load Cortex-M4 firmware if I load the firmware of Cortex-M4 in Retent...
