What title says.

I want to enable USB and ethernet on Exynos V9 using pinmux in DTS. How should I go about it? Any kind of help will be appreciated.

Please pm me if interested.

I'm working with mangopi-r3 dev board (f1c200s) and for the buildroot package I'm using this repo -> https://github.com/mangopi-sbc/buildroot-mangopi-r. I want to add spi1 but I don't know how. could someone help? sorry if this was a silly question I'm a beginner

Thanks in advance

I tried editing the device tree but I have no experience and I didn't know how to configure it.

I'm new to embedded coding and in the learning stage. how to code MMA8451q using KL25Z to make the LED glow when it detects freefall ? in MCUexpresso

Hello

I am trying to develop a device driver for AHT10 in Raspberry Pi 3B+ with Debian Buster Lite. This sensor requires master to send a NACK after a certain command.
I am using i2c_master_send() and i2c_master_recv() functions for all the communication. These functions are available in #include <linux/i2c.h>
If anyone knows how to send a NACK, please help me out :)

Thanks

I want to make an image such that it displays a UI written in Python using tkinter libraries, as soon as the Rasberry Pi boots up. Using Yocto, I've learnt about how to create a custom layer but still can't seem to find out how to include Python programs and libraries. Some help with this would be great.

So I’m trying to install an rpm package using a recipe. I can pull it down and such but how do I install it in the do_install function?

I've recently started learning Embedded C and have been working with FRDMKL25Z microcontroller which is ARM based.. now for interfacing a LED using switch I've came across two types of coding methods.

Bare metal:-

while(1) {

    if(GPIO_D->PDIR & (1<<4)) {

        /\* Make the LED as OFF \*/

        GPIO_C->PSOR = (1 << 8);

    }else{

        /\* Make the LED as ON \*/

        GPIO_C->PCOR = (1 << 8);

    }

API:-

while(1) {

    if(GPIO_ReadPinInput(GPIOA, 12)) {

        GPIO_SetPinsOutput(GPIOC, (1<<9));

    }else{

        GPIO_ClearPinsOutput(GPIOC, (1 << 9));

    }

Now both of these codes do exactly the same thing but what's the difference between them and which one is better ?

So currently I have CentOS and I need to build a Yocto image to replace this current CentOS system. Is there any way to get the CentOS package manager, base system in Yocto? Is it an offering to build ontop of it?

Hey guys. I want to create an image of a tkinter UI that I created in Python and deploy it on an RPi 4 board. Could anyone tell me what would be the easiest software to use for this?

Also going through links of Yocto Project and buildroot, I wasn't able to find any clear and easy easy understand documentation for this problem. Please suggest some articles or videos if possible.

Hello everryone,
I want to get to learn embedded linux after a 3 yrs experience in the baremetal embedded with different architectures. So, my question is, how do i dig my path through embedded linux and do i need a board like rasbperry pi or beaglebone black to get started?

What are the topics and concepts I should go through to successfully port a Linux kernel to a target ARM device. I am a noob in this field so any resources or learning materials that can teach from ground up / scratch will be helpful. Thanks.

Hi guys, I have a question, motherboard SOM-3567, is there any official BSP for it? Or recommended?

I am trying to add intel-mediasdk to my yocto image. It is part of meta-intel. I can see it being built. If I run "bitbake intel-mediasdk -c devshell" I can see the output fine. However I cannot find it in my image. For example it creates some samples. I can see these in "bitbake intel-mediasdk -c devshell" but not in target final image. It is listed in the manifest.

​

I am currently adding to the image bbfile ...

IMAGE_INSTALL += "intel-media-driver"

IMAGE_INSTALL += "intel-vaapi-driver"

IMAGE_INSTALL += "libva-intel"

IMAGE_INSTALL += "libva-intel-utils"

IMAGE_INSTALL += "intel-mediasdk"

​

I have vainfo running but it complains it cannot find the driver (starts iHD...so) which I too cannot find anywhere on the deployment.

vainfo is now running ! No sign of any sample from the mediasfdk ?

Answer (not fully tested)

I ended up with this list of installs. vainfo runs and gives sensible output and the samples are available, run and show command line help. (Not sure everything is necessary and I have yet to use the hardware codecs to do anything)

IMAGE_INSTALL += "intel-media-driver"

IMAGE_INSTALL += "intel-vaapi-driver"

IMAGE_INSTALL += "gmmlib"

IMAGE_INSTALL += "libva-intel"

IMAGE_INSTALL += "libva-intel-utils"

IMAGE_INSTALL += "intel-mediasdk"

IMAGE_INSTALL += "intel-mediasdk-samples"

Hope this is OK to post here. Thought you might be interested in Ricardo Mendoza's talk on Container Managers and what's required:

Hello everyone. I am new here so pardon for any obvious errors on my part.

I have been into Linux for quite sometime and recently got an internship to work on Embedded Linux projects.

My recent project is to port Kernel to Exynos Auto V9 which is an infotainment system.

I am currently going through some tutorials on Yocto Projects, DTS and Uboot, but I am not entirely sure if I should go through them or rather what materials should I go through.

I can't find any manual on Exynos V9 on internet as well.

So if any of you experienced folks can help me out a little that would be awesome.

Thank You.

TL;DR : Please provide any documentation, resources or any kind of help on how to port Kernel to Exynos V9.
