Can't build Yocto sdk for FRWY-LS1046A

[srogers]

Hi

I am trying and failing to build a Yocto cross compile toolchain for the LS1046. I am doing this so that I have a cross compiler for building applications for this target.

Here's what I've tried:

• On Ubuntu 20.04 LTS: repo init -u https://github.com/nxp-qoriq/yocto-sdk.git -b langdale -m ls-6.1.1-1.0.0_distro.xml, repo sync, source ./distro-setup-env -m ls1046afrwy, bitbake ls-image-lite, bitbake ls-image-lite -c populate_sdk
• On Ubuntu 22.04 LTS: repo init -u https://github.com/nxp-qoriq/yocto-sdk -b mickledore -m ls-6.1.55-2.2.0_distro.xml, repo sync, source ./distro-setup-env -m ls1046afrwy, bitbake ls-image-main, bitbake ls-image-main -c populate_sdk

Both these will successfully generate yocto builds but the sdk steps fail at the end.

On Ubuntu 20:

Is there a Yocto build which will generate a cross compile toolchain for the FRWY-LS1046A?

Hi @srogers,

Could you please make sure that all the packets are installed in your hosts (Ubuntu 20.04 and 22.04)?

[srogers]

Yes all the packages are installed.

Please try to follow steps in LLDPUG - 6.4.1 Environment setting for cross-compiling and build again.

I understand,

Let me try to reproduce your issue on my side to find a solution for you.

A Yocto Project build requires some packages that must be installed for the Yocto Project build.
To set up the Yocto Project build, navigate to the Yocto Project Quick Start and check for the packages that
must be installed for your build machine.
The essential Yocto project host packages are given below:
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm rsync curl

After this:

Install the repo utility: 

$ mkdir ~/bin
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ PATH=${PATH}:~/bin

Download the Yocto Project BSP for Layerscape

$ mkdir distro
$ cd distro
$ repo init -u https://github.com/nxp-qoriq/yocto-sdk.git -b mickledore -m ls-6.1.55-2.2.0_distro.xml
$ repo sync

 Start a layerscape build in distro folder:

$ source distro-setup-env -m ls1046afrwy

 Build the layerscape image:

$ bitbake ls-image-main # build main image for networking feature

# generate composite firmware for Layerscape machines
$ bitbake qoriq-composite-firmware
$ bitbake generate-boottgz

Thanks for the reply but it does not answer my question. You describe how to build a Yocto image which I can already do.

The next step fails - bitbake ls-image-main -c populate_sdk. This should generate a cross compile toolchain to allow developers to install the cross-compiler for this target.
