How to get started with i.Mx 8 ?

anaseem · ‎06-03-2019

I just purchased and powered up i.MX 8QuadXPlus MEK CPU Board. I'm interfacing with the board from host terminal. On powerup, U-Boot runs. Name of CPU, memory size and lots of information is displayed on the terminal. Then, it says, Starting kernel . . . lots of information is displayed such as Virtual kernel memory layout. Then, it says

Welcome to NXP i.MX Release Distro 4.14-sumo (sumo) ! What does this mean?

I cannot tell if Linux mounted a root file system.

After displaying lot more information, I get login prompt as follows:

imx8qxpmek login:

Is Kernel done executing, I don't see any indication that User init program is running? Is the board shipped with user init program?

My goal is to use this board to develop embedded USB Host. What do I need to learn about Linux to get started? What's my next step?

I entered <root> at login prompt. Now I get following prompt:

root@imx8qxpmek:~#

What do I enter at this prompt?

Hi,

You have already reached the file system and now you are at the system prompt. All the information you saw after "Starting kernel" is the kernel booting and now you are ready to go. At that point, you can start using it as any other (or almost) Linux computer. For some customizations and custom user applications you might require to build and install your own Yocto image. This might be a good start point for you:

iMX8 Application Media Processor | iMX8 Processor | RidgeRun

Hello,

I'm not ready to create custom user applications yet. This means I won't need Yocto yet.

First, I want to create and run simple 'C' language "Hello World" program in MEK. What are my options for doing that?

one can look at SDK_MEK-MIMX8QX (attached document Getting Started with

MCUXpresso SDK for i.MX 8QuadXPlus.pdf describes Hello World example)

I haven't developed in Linux before. Is Yocto image Linux distribution?

How do I get started with embedded Linux based development using MEK development platform? What software tools do I use to ? What is system address space? where do I place my application code?

What documentation do I need?
