I got the Onion Omega2 Pro last month. I like it because:
- The CPU is MIPS architecture, allowing me to gain some experience with this unfamiliar architecture.
- It has 8GB eMMC storage, giving me plenty of space to install packages.
- It has LiPo battery port, USB host port, and pin headers with SPI and I2C, leaving possibility of building battery-powered IoT projects.
However, I'm unhappy with OnionOS. Apart from GUI differences, it uses a custom WiFi driver
wifi-warp-core that has several flaws. Most notably, my WiFi SSID is
+ (a plus sign), and the Onion would not connect to it. I want to replace OnionOS with a standard OpenWrt installation!
I figured out how to do that, and wrote up a guide in case others have the same need:
The outcome would be an Omega2 Pro with normal OpenWrt 18.06 WiFi driver complete with Luci user interface, installed to the 8GB eMMC storage.
