Install Operating System

Introduction

The LinkStar-H28K has two Gigabit network ports that use PCIE/RGMII gigabit technology and a Quad-core chip. It has LPDDR4X 4GB memory and 8GB eMMC storage that can be expanded up to 512 GB with a TF card. It also has a 5V-12V Type-C connection for PD (Power Delivery) capability. In this wiki we will show you how to install operating system with TF card or eMMC.

Select the system you need for H28K

The H28K supports Qwrt operating system. In this section, we will bring you the installation method for Qwrt system.

Notes & Instructions

H28K has two types of storage, one is TF card storage and the other is eMMC storage. Both memories are available for flash memory systems.

In this chapter, we can use the TF card with a card reader to flash the system to the TF card.

We can also flash the system to the eMMC that comes with the H28K.

When a TF card is inserted in the H28K, the system in the TF card is the one that boots up when the system is turned on, as the TF has priority to boot.

caution

When using a TF card with H28K, it is important to note that it may be incompatible with some high-speed cards. If you are using a high speed card, you may experience data loading errors, boot-up errors or malfunctions during power-up and loading of the system due to the speed of the card.

The advantage of using a TF card is that different networks can be configured with different TF cards. It is also possible to have multiple systems - different systems can be used by replacing different TF cards.

Procedure

Step 1. Connect the TF to the PC

Please put the TF into your prepared card reader and connect it to your PC.

Step 2. Flash the system onto a TF card

Open the balenaEtcher which has been installed in advance.

Select the QWRT firmware you downloaded, it should end in .img.

Select the drive you want to flash the system to.


Click the Flash button and the software will flash the system into your TF.

caution

Some computers may prompt whether the USB device is not recognised after flashing the system and whether to format it, please do not reformat the card or the system inside will be erased.

Step 3. Boot QWRT from the TF card

Remove the TF card from the card reader and insert it into the TF card slot of the H28K.

Then power up the H28K, you can choose to power it via USB-C-5V.

Step 4. Manage the QWRT backend

Use a network cable to connect to the ETH0 network port of the H28K. Then enter the address: 192.168.1.1 into your browser to access the admin backend.

caution

ETH0 is the LAN port and the ETH1 port is WAN ports. If you want to manage H28K's QWRT via a network cable, then connect the network cable to ETH0.
