IOT-DIN-IMX8PLUS: Yocto Linux: Installation

Overview

This article provides instructions needed to install the Yocto Linux live image onto the Compulab IOT-DIN-IMX8PLUS internal storage.
The recommended installation procedure is using a host PC with a Debian-based operating system.

Preparing the workstation

• Obtain a Debian-based workstation with a free USB port.
• Install bmap-tools package if not installed
• Obtain a USB flash drive. Any commercially available USB flash drive of 4GB (or larger) may be used for the installation.
• Plug the USB flash drive into the host PC. From now we assume the device name of the flash drive on your Linux PC is /dev/sdX.

Preparing the Yocto Linux live image

• The Yocto Linux live image and block map file (bmap), mentioned below, are generated during the Building IOT-DIN-IMX8PLUS Yocto process:

• Live image archive: fsl-image-network-full-cmdline-iotdin-imx8p.rootfs.wic.zst
• Block map file: fsl-image-network-full-cmdline-iotdin-imx8p.rootfs.wic.bmap

Preparing Installation Media

• Unpack the image archive:

zstd -dc fsl-image-network-full-cmdline-iotdin-imx8p.rootfs.wic.zst > fsl-image-network-full-cmdline-iotdin-imx8p.rootfs.wic

• Flash the image file to the USB flash drive by the means of bmaptool utility:

sudo bmaptool copy ~/path/to/fsl-image-network-full-cmdline-iotdin-imx8p.rootfs.wic --bmap ~/path/to/ fsl-image-network-full-cmdline-iotdin-imx8p.rootfs.wic.bmap /dev/sdX

Run Yocto Linux live image

• Insert the USB flash drive into the USB3.0 port located on the front panel
• Power on the device
• Wait for the automatic Linux login

Installing Yocto images onto the internal storage

• Invoke cl-deploy utility

root@iotdin-imx8p:~# cl-deploy

• Select /dev/mmcblk2 as a destination device
