How to install apt-get on i.mx8m mini linux image

[jefflfree]

I put Linux 4.14.78_1.0.0_ga_images_MX8MMEVK onto the i.mx8m mini and it boots just fine.

I want to enable to enable i.mx8m mini evk to function as a WAP by installing hostapd.

Assuming this is possible, what are the steps to install "apt-get" onto the i.mx8m mini. I have a debug terminal to the linux prompt but I am stuck. How do I add applications?

[Maybe you can provide me a pointer to how to add individual components to the SD card like apt-get?]

Ok. I am able to build an image. However I cannot install hostapd on the target system.

Here are the steps I did trying to get hostapd to the target system:

Added the following to conf/local.conf:

PACKAGE_CLASSES ?= "package_rpm"

EXTRA_IMAGE_FEATURES = "debug-tweaks package-management"

IMAGE_INSTALL_append += " apt hostapd"

Then I ran bitbake:

$ bitbake fsl-image-qt5-validation-imx

and got this:

...rpm-software-management.dnf.git/ does not exist

If I remove package-management, it will build. But then on the target system I cannot install hostapd.

When I read the documentation, it seemed to indicate that I need to create a web-server on the development system (package feed) to serve the packages to the target system. Can someone just supply an example of what I need to do to get hostapd package installed?

update: hostapd is on the target system now. I just cannot install other packages from the host system. I guess I will have to leave off package-management for now.

I am finding that to build a linux image, it is exceeding the disk space I have (more than 50GB). Is there an image already build that include apt-get?

I made progress. I did not realize I needed 120GB to build linux!

Here is my recipe using Ubuntu 18.04.2

$ DISTRO=fsl-imx-wayland MACHINE=imx8mmevk source fsl-setup-release.sh -b build-wayland

$ bitbake fsl-image-qt5-validation-imx

$ bunzip2 -dk -f fsl-image-qt5-validation-imx-imx8mmevk.sdcard.bz2
$ sudo dd if=fsl-image-qt5-validation-imx-imx8mmevk.sdcard of=/dev/sdb bs=1M conv=fsync

There was a note that said fsl-imx-wayland and fsl-imx-fb are not supported on i.MX 8. If this applies to imx8mmevk, then should I be using fsl-imx-xwayland ?

I installed to sdcard and I am getting a reset loop over and over. Any clues how to debug this?

ok. I solved the reset loop issue. I had incorrectly written the image to the sdcard.

[im_tlau]

Hi Jeff,

I'm trying the same thing building imx8mm image for evk board, could you let me know what's your steps/commands of writing the imsage to the sd card?

Thanks!

[jefflfree]

Assuming you were able to build the image using Yocto.

Note: I am running Ubunto 18.04.2 on VirtualBox with a Shared Folder to my windows laptop

cd build-wayland/tmp/deplay/images/imx8mmevk

# Since the sdcard image is compressed, we need to uncompress it

bunzip2 -dk -f fsl-image-qt5-validation-imx-imx8mmevk.sdcard

cp fsl-image-qt5-validation-imx-imx8mmevk.sdcard /media/sf_VirtualBox_Shared

From Windows, I used Rufus to then take the image from the shared folder and write to sdcard which was plugged into my laptop.

(I found this much easier than doing what some people do where they follow this (Access SD Card on Linux from Windows using VirtualBox | Tech Blog)

Then I physically took sdcard and put it into the evk and booted.

[im_tlau]

Thanks Jeff!

It's interesting that cp command does the job, I use dd to dump my .sdcard image to MicroSD card, my problem was resolved, I had to use own built  fsl-image-validation-imx-imx8mmddr4evk-rootfs.sdcard for my iMX8MM DDR4 EVK board, without ddr4 it won't work.

Also good to know Rufus tool for Windows.

[joanxie]

we have tested that built fsl-imx-xwayland on ubuntu 16.04 successfully, maybe you can try this, if you don't use sdcard image, how about the demo sdcard image? the same issue?

[joanxie]

if you need to install hostapd, you should build the image by yourself, you need to add the hostapd in the local.conf, then build the image you need, for more detailed information, you also can refer to the yocto traning document:

https://community.nxp.com/docs/DOC-94849 

[jefflfree]

Since my post I found a linux manual at https://www.nxp.com/webapp/Download?colCode=imx-yocto-L4.14.98_2.0.0_ga which seems like it talks about uboot etc... Is this the path I should be heading?

[joanxie]

I couldn't open your link, if you means 4.14.98 linux documents, yes, you can refer to that, you can refer to the yocto user guide, which tell you how to download and build the 4.14.98 source code and get your own image

[jefflfree]

I found the proper link: https://www.nxp.com/design/i.mx-developer-resources/i.mx-software-and-development-tool:IMX-SW

This is the only one that had the 2019 version of Yocto. Under Linux->Linux L4.14.98_2.0.0 Documentation

Is this what I am supposed to follow?

[joanxie]

you can refer to the link as below:

https://www.nxp.com/design/software/embedded-software/linux-software-and-development-tools/embedded-...

the latest version for imx8MM is 4.14.98

[jefflfree]

thx. So, I am following i.MX Yocto Project User's Guide to build an image.

Will this by default include apt-get or would this be considered "customization"? If so, are there any examples on how to do this?
