This page provides details for flashing the webOS Open Source Edition (OSE) image to a microSD card. In addition, this page describes how to verify the flashed image on the target device.
Make sure you have completed the following:
Build the webOS OSE image on a Linux machine. For more information, see Building webOS OSE. To flash the image from Windows or macOS, you must copy the built image from the Linux machine.
Insert a microSD card in the microSD card reader device connected to the host machine.
This section describes how to flash the webOS OSE image to a microSD card, for each host operating system.
Flash the image using Win32DiskImager.
First, change directory to where the image is located.
$ cd <path where the image is located>
Check the device name of the microSD card using the following command.
$ sudo fdisk -l
To flash the image to the microSD card, run the following commands.
$ sudo umount /dev/sd<xN>
$ sudo dd bs=4M if=./<webOS OSE image> of=/dev/sd<x>
$ sudo umount /dev/sd<xN>
sd<xN>
denotes the device name of the microSD card, where N
is a number suffix.dd
command, you must pass sd<x>
(without the suffix number) to the of
operand. sd<x>
indicates the mass storage device, not the partition.$ sudo umount /dev/sdb1
$ sudo dd bs=4M if=./webos-image-raspberrypi4.rootfs.wic of=/dev/sdb
$ sudo umount /dev/sdb1
First, change directory to where the image is located.
$ cd <path where the image is located>
Check the device name of the microSD card using the following command.
$ diskutil list
To flash the image to the microSD card, run the following commands.
$ sudo diskutil umountDisk /dev/disk<N>
$ sudo dd bs=4m if=./<webOS OSE image> of=/dev/rdisk<N>
$ sudo diskutil umountDisk /dev/disk<N>
disk<N>
denotes the device name of the microSD card, where N
is a number suffix.dd
command, you must pass rdisk<N>
to the of
operand to speed up the copying process.$ sudo diskutil umountDisk /dev/disk2
$ sudo dd bs=4m if=./webos-image-raspberrypi4.rootfs.wic of=/dev/rdisk2
$ sudo diskutil umountDisk /dev/disk2
After you finish flashing the webOS OSE image to the microSD card, you can check how it works by taking the following steps:
For webOS OSE 2.19.0 or Higher
After starting up the target device, you will see the App Bar popping up from the bottom side of the screen. App Bar should contain a list of pre-installed apps, as shown in the figure below.
For more details on how to use webOS OSE UI, see webOS OSE UI Guide.
For webOS OSE 2.0.0 ~ 2.18.0
After starting up the target device, you will see the Home Launcher UI popping up from the bottom side of the screen. Home Launcher should contain a list of pre-installed apps and icons for quick access menu, as shown in the figure below.
The names of quick access menu icons are as shown below. Currently, only the icon for System Settings app is working. The others will be implemented in a future release.
If you want to close the Home Launcher, tap the outside of the Home Launcher. Swiping up from the bottom of the screen will show the Home Launcher again.
For webOS OSE 1.x
Press the Windows key (Linux, Windows) or the right command key (macOS) on your keyboard, and you will see the Home Launcher UI popping up from the right side of the screen. Home Launcher should contain a list of pre-installed apps and an icon for Settings app, as shown in the figure below.
