linux kernel version

[sergio_dorazio]

Hi,

I have a imx6ull evk board. Few years ago I worked with v4.14 linux kernel version downloaded from NXP site. Now in the NXP site there is v6.1 linux kernel. But today I need to work with v4.19 linux kernel version. What is the repo command to download the 4.19 version ? (for example : "repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-langdale -m imx-6.1.1-1.0.0.xml"  is the command to get v6.1 version ). What is the ubuntu host version to compile this kernel version ?

By, Sergio D'Orazio.

Hello @sergio_dorazio 

Please try to use:

repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-warrior -m imx-4.19.35-1.1.0.xml

Best regards.

Hi, thank you for the ansewer,
the link that you send me is correct, but when I run bitbake command I have errors:

My command sequence is:

cd imx-yocto-bsp-4.19/
repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-warrior -m imx-4.19.35-1.1.0.xml
repo sync
DISTRO=fsl-imx-fb MACHINE=imx6ull14x14evk source fsl-setup-release.sh -b Linux-evk
bitbake core-image-minimal

Is it correct ?
if no, can you send me the correct sequence ?

I am using a Pc with UBUNTU 22.04 , is it correct ?

By Sergio.

[Alejandro_Salas]

Hello @sergio_dorazio 

I tried do the compilation with your steps, there are correct, and I am totally able to compile the image.

The only difference that I have is the Ubuntu version. I am using Ubuntu 20.04.6 LTS.

Also, remember install the necessary host packages:

sudo apt-get install gawk wget git diffstat unzip texinfo gcc-multilib \ build-essential chrpath socat libsdl1.2-dev 

If you can't install all the packages with that command, try to install individually.

Let me know how it was.

Best regards!

[sergio_dorazio]

I Alejandro,
I have installed the host packets ( only libsdl1.2-dev is been installed, the others packed are already present on host)
but I have the same problem.
In the same host, the last NXP kernel version (v6.1) works well.
What is your suggestion ? I will reinstall an Ubuntu old version for compile kernel v4.19 ?

Hello @sergio_dorazio !

Please try to modify the file (yocto-compilation-folder)/sources/meta-imx/meta-ml/recipes-devtools/python/python3-pybind11_2.5.0.bb 

EXTRA_OECMAKE =  "-DPYBIND11_TEST=OFF \
		-DPYTHON_EXECUTABLE=${RECIPE_SYSROOT_NATIVE}/usr/bin/python3-native/python3.7 \
"

Let me know if this works for you.

Best regards.

hi Alejandro,
sorry for delay but I was busy in other works.
In my PC , the file /sources/meta-imx/meta-ml/recipes-devtools/python/python3-pybind11_2.5.0.bb not exist.
I found this file /sources/meta-openembedded/meta-python/recipes-devtools/python/python3-pybind11_2.2.3.bb
I have done the modify in this file but the error not change.
Which python3-xxx.bb file is called in my project ?
Have you other suggestion ?

[Alejandro_Salas]

Hello @sergio_dorazio 

Please try to do in a python terminal this command:

>>> from collections import MutableMapping

If you have the error: 

ImportError: cannot import name 'MutableMapping' from 'collections'

Please try to change the name of the package (collections to collections.abc) in the specific file from your log:

ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)

example: >>> from collections.abc import MutableMapping 

Please try it and let me know.

hi Alejandro,

- sources/poky/bitbake/lib/bb/data_smart.py
- sources/poky/bitbake/lib/bb/persist_data.py

But in the bitbake compilation I have errors :

Have you suggestion for errors correction ?

Hello @sergio_dorazio 

I am facing the same issue, I believe is a problem with Ubuntu version, let me try to do the compilation in a machine with Ubuntu 18.04, that is the recommended to compile this Linux version.

Best regards.

[Alejandro_Salas]

Hello @sergio_dorazio !

I am checking the issue, when I have an update I will let you know, I believe there is not necessary change your Linux host version.

Best regards!
