Step 4 Build Uboot HLK-RM04
In this step we install a set of tools that allow you to build the Uboot loader. This is not generally required because I have created two Uboot images for your use. However if you want to change Uboot this…
Step 3 Ubuntu12 Install
The build environment for HLK-RM04 development is quite easy to setup on a Linux computer or virtual machine. I have used Ubuntu12 for this project and I would suggest starting there because the build dependencies are already worked out for…
Step 2 Install Openwrt
It has been a long time coming but we are finally ready to install OpenWRT. I have provided a pre-built image for this. Using the Uboot loader we can install a new Linux image on our module. This only takes…
