Introduction

How to compile Yocto 4.2 on the new Advantech NXP BSP? Based on NXP Yocto 4.2-6.1.36 version + Advantech Meta Layer

Step 1: Initialize Yocto Environment​

$ git config --global user.name "Your Name"
$ git config --global user.email "Your Email"
$ git config --list

$ mkdir imx-yocto-bsp
$ cd imx-yocto-bsp
-----------------------------------------------------
### If you suffer "server certificate verification failed", you can use the following command to disable SSL verification in git repositories with self-signed certificates
### If you get "The unauthenticated git protocol on port 9418 is no longer supported.", you can try "git config --global url."https://".insteadOf git://"
-----------------------------------------------------
$ export GIT_SSL_NO_VERIFY=1
$ git config --global http.sslverify false
$ git config --global url."https://".insteadOf git://
-----------------------------------------------------
$ repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-mickledore -m imx-6.1.36-2.1.0.xml
$ repo sync

Step 2: Get Advantech Meta Layer​

$ cd sources
$ git clone https://AIM-Linux@dev.azure.com/AIM-Linux/meta-advantech-nxp/_git/meta-advantech-nxp -b mickledore-6.1.36
$ mv meta-advantech-nxp meta-advantech

Step 3: Compile Yocto​

Example for XWayland and imx8mprsb3720a2 board:

$ MACHINE=imx8mprsb3720a2 DISTRO=fsl-imx-xwayland source ./imx-setup-release.sh -b rsb3720

Enabling the Advantech BSP Layer​

To enable the layer, add the following line to the end of conf/bblayers.conf:

BBLAYERS += "${BSPDIR}/sources/meta-advantech"

Then start the build:

$ bitbake imx-image-core
