Using
The most common way of using this Nerves System is create a project with mix nerves.new and add mangopi references where needed and in a similar way
to the default systems like bbb, etc. Then export MIX_TARGET=mangopi.
See the Getting started
guide
for more information.
If you need custom modifications to this system for your device, clone this repository and update as described in Making custom systems.
Console access
The console is configured to output to the UART on pins 8 and 10 on the 40-pin GPIO connector. This is just like the Raspberry Pi. A 3.3V FTDI cable is needed to access the output.
Networking
The board has two network interfaces, a WiFi module and a virtual Ethernet on the USB C connector marked “OTG”.
Thanks
Since there aren’t many RISC-V boards out, it took a bit of searching to figure out how to bring this board up. The key was finding out that it’s a trimmed down version of the Nezha board since it’s possible to find decent device tree configurations and Linux configurations that actually work. Everything in this repository derives from that and not from Tina Linux. The Linux kernel comes from smaeul’s Allwinner D1 Linux fork.
