IOT-DIN-IMX8PLUS: Yocto Linux: Installation
Contents
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
