OpenWrt One
The OpenWrt One is the OpenWrt project’s own reference router. The OpenWrt project designed it, and Banana Pi manufactures and sells it. It is built to be hard to brick. The bootloader and Linux live on SPI NAND, while a write-protected SPI NOR holds a recovery system. A switch picks which one the board boots from. Mainline Linux device-tree support is being upstreamed.
