zeus-5.4.24-2.1.0 won't boot on my IMX8MNEVK board

[simon_pettersso]

Hi!

I'm trying to get the 5.4.24-2.1.0 release to run on my IMX8MNEVK board but I get the following error when trying to boot the image:

U-Boot SPL 2020.04-5.4.24-2.1.0+g4979a99482 (Jul 07 2020 - 07:18:12 +0000)
Can't find PMIC:PCA9450
DDRINFO: start DRAM init

The steps I take are the following

1. Create a Dockerfile

2. Build

docker build --build-arg GID=$(id -g) \
    --build-arg UID=$(id -u) \
    --build-arg USER=$USER \
    -t yocto-build \
    .
mkdir build
docker run --rm -it -v$PWD/build:/home/$USER/build yocto-build /bin/bash
git config --global user.name "XXX YYY"

repo sync
MACHINE=imx8mnevk DISTRO=fsl-imx-wayland source imx-setup-release.sh -b build
bitbake core-image-minimal
exit # get out of docker

3. Install image to SD-card

cd build/tmp/deploy/images/imx8mnevk/
bzip2 -df core-image-minimal-imx8mnevk-2020*.wic.bz2
cat core-image-minimal-imx8mnevk-2020*.wic | sudo dd of=/dev/sda bs=1M iflag=fullblock oflag=direct conv=fsync

I've tried to build additional images but they all fail, for example the core-image-base image fails with

NXP should fix this.

nxp-wlan-sdk recipe is the problem here. Nothing to do with the host. 
Add:

EXTRA_OEMAKE += "KERNELDIR=${STAGING_KERNEL_BUILDDIR}"

to meta-bsp/recipes-connectivity/nxp-wlan-sdk/nxp-wlan-sdk_git.bb or an append file.

Just to add the conversation. I come across the same issue nxp-wlan-sdk when compiling a full image (5.4.70.2.3.0) inside a Docker container and link directories workaround worked out. 

A colleague compiled another fulll image with Zeus 5.4.70.2.3.2  inside Docker and he didn't see any issue at all. It seems that problem was fixed starting from that release. Thank you all for sharing your experience.

Simon,

I have a fix for this on WSL2 which I believe is also applicable to Docker.

The makefile for nxp-wlan-sdk uses:

KERNELDIR ?= /lib/modules/$(KERNELVERSION_X86)/build

on WSL2 that is resolving to 

/lib/modules/4.19.104-microsoft-standard/build

On my WSL2 machine there is nothing in /lib/modules

On a working Ubuntu VM, there is a folder: 5.4.0-26-generic which was probably already there or was installed at some point. They come from the package linux-headers-generic.

There aren't any Microsoft releases of this package so I installed the generic headers.

Installing linux-headers-generic in WSL2 resulted in an install of /lib/modules/5.4.0-40-generic

To fix this, I linked the generic version to the one the Makefile needs.

• apt-get install linux-headers-generic
• ln -s /lib/modules/5.4.0-40-generic /lib/modules/4.19.104-microsoft-standard

then the build worked.

In your case, I think you would need to link to 5.4.49 instead of 4.19.104-microsoft-standard

I hope this works for you.

P.S. to the moderator, sorry about all of the edits but I am finding it impossible to format this message.

[david_datta]

I have successfully built and run a Docker image that fixed this issue.

I used:

FROM ubuntu:20.04

...

# Fix for nxp-wlan-sdk missing libraries
RUN apt-get install -y linux-headers-generic
RUN ln -s /lib/modules/5.4.0-40-generic /lib/modules/4.19.76-linuxkit

# Add "repo" 
...

I also have encountered this issue when updating our imx6ull system from 4.9 /rocko to 5.4/zeus. I am running a Docker container that pulls in 19.10. Will see if it exists on 18.04 before I try the ln -s workaround.

cheers!

[tylernol]

18.04 has this as well, but nxp-wlan-sdk is looking for another version. My workaround mod to my Dockerfile for ubuntu 18.04 base image is :

# Fix for nxp-wlan-sdk missing libraries

RUN apt-get install -y linux-headers-generic

# for 18.04

RUN ln -s /lib/modules/4.15.0-112-generic /lib/modules/4.4.0-21-generic

[davidvescovi]

for my build under WSL2 Ubuntu 20.04 I had to do:

sudo apt-get install -y linux-headers-generic

sudo ln -s /lib/modules/5.4.0-42-generic /lib/modules/4.19.104-microsoft-standard

Note:4.19.104 is the Microsoft release version that may change see:

Hello Simon Pettersson,

I’m not very familiar with containers, but it could be that the host environment does not have all the requirements to build the BSP Release images. The core-image-minimal recipe is part of the Yocto Project and it does not have the same package dependencies as some of the other recipes from the BSP Release.

You will see that the recommended host configuration is Ubuntu 16.04 or 18.04 with a list of required packages. While Yocto can tun on many Linux Distributions, the BSP Release for i.MX requires Ubuntu of these specific versions. I see that the container is set to Ubuntu but I would first make sure that it is the right version and that all requires packages are installed. You can find more details on the i.MX Yocto Project User’s Guide that’s part of the BSP documentation.

I hope this helps!

Regards,

[simon_pettersso]

Hi!

That is a very good point. I use Ubuntu Bionic (18.04) as a base container and add the required packages plus a few more required to build, but as you mention there could be something missing that's not mentioned in the i.MX Yocto Porject User's Guide.

I backtracked to the 5.4.3-1.0.0 version and that core-image-minimal can boot, but it has the same problem to build the other images. I haven't tried the 5.4.3-2.0.0 version yet, I will report back to this thread as soon as I've tried it out.

[bernhardfink]

Your boot environment settings indicate that you have the new 8M Nano EVK with LPDDR4 and the PCA9450 PMIC.

Is this the case?

Regards,

Bernhard.

[simon_pettersso]

Yes that is correct.
