The board helpfully reads "Merrii Vision"(in Chinese), "www.merrii.com" on the PCB.
- For building u-boot, use the "Merrii_Hummingbird_A20" target.
- The .fex file can be found in sunxi-boards as merrii_hummingbird_a20.fex
Everything else is the same as the manual build howto.
Use the sun7i-a20-hummingbird.dts device-tree file for the mainline kernel.
Tips, Tricks, Caveats
The "U-boot" button triggers FEL mode.
Adding a serial port
There is a nice 2.54mm pitch connector between the NAND and the µSD slot, the pin-out is printed right next to it. Just attach some leads according to our UART howto.
