Pine64 Ox64 BL808 (64-bit RISC-V SBC) is now supported in NuttX Mainline! (Many thanks to my reviewers)
Ox64 BL808 is an affordable $8 SBC with: - 3 x RISC-V Cores (T-Head 64-bit / 32-bit) - Networking: Ethernet, WiFi, Bluetooth LE, Zigbee - Peripheral Interfaces: UART (Serial), I2C, SPI, USB, MIPI CSI - Interrupt Controller: CLINT and PLIC - Memory Management: Sv39 MMU - OpenSBI Supervisor Binary Interface and U-Boot Bootloader - Bootable microSD: Boot NuttX and Linux But there's a catch: - Limited RAM (64 MB): It's not for gaming and servers - Flash Memory is Empty: Needs a One-Time Flashing (via a USB Serial Adapter) - Barebones Form Factor: Fits on a Breadboard, Ethernet is optional In this article we walk through the steps to: (1) Flash into Ox64 the U-Boot Bootloader and OpenSBI (2) Boot Linux on a microSD Card (3) Do the same to boot NuttX RTOS (4) Run some Bare Metal Experiments inside the NuttX Kernel Check out the article here: https://www.hackster.io/lupyuen/8-risc-v-sbc-on-a-real-time-operating-system-ox64-nuttx-474358 Lup
