The FriendlyElec NanoPi R28S is a dual gigabit Ethernet router board
based on the Rockchip RK3528 SoC. It shares most of its design with the
NanoPi Zero2.
Specifications:
- SoC: Rockchip RK3528, quad-core Cortex-A53 @ 2.0 GHz
- RAM: 1 GB LPDDR4
- Storage: microSD slot, optional onboard eMMC
- Ethernet: 1x GbE (GMAC1 + Realtek RTL8211F),
1x GbE (Realtek RTL8111H over PCIe)
- WiFi: AICSemi AIC8800D80 over SDIO
- USB: 1x USB 2.0 Type-C (power input and OTG)
- UART: USB Type-C debug console (onboard WCH CH340E), 1500000 8N1
- Buttons: user (GPIO), MaskROM (SARADC)
Add support for the board based on the NanoPi Zero2, and enable
CONFIG_BUTTON_GPIO for the user button.
Features tested on NanoPi R28S:
- SD-card boot
- Ethernet
