Introduction​

LuckFox Pico 、Luckfox Pico Mini A/B and LuckFox Pico Plus are low-cost micro Linux development boards based on the Rockchip RV1103 chip, while LuckFox Pico Pro and LuckFox Pico Max are low-cost micro Linux development boards based on the Rockchip RV1106 chip. RV1103/RV1106 is a highly integrated IPC visual processing SoC designed for AI-related applications. It is built on a single-core ARM Cortex-A7 32-bit core with integrated NEON and FPU, and features a built-in NPU that supports INT4/INT8/INT16 mixed operations, with a computing power of up to 0.5 TOPs.

Furthermore, it features a new hardware-based ISP that supports various algorithm accelerators such as HDR, 3A, LSC, 3DNR, 2DNR, sharpening, haze removal, gamma correction, and more. Additionally, it has a built-in 16-bit DDR2 DRAM to maintain demanding memory bandwidth, as well as built-in POR, audio codec, and MAC PHY. In essence, the RV1103 is a powerful processor suitable for various AI application scenarios.

This development board is suitable for applications in various scenarios, including but not limited to:

  • Smart home devices
  • Industrial automation equipment
  • Robots and drones
  • Intelligent monitoring devices
  • Intelligent transportation equipment
  • Smart medical devices

The development board supports multiple interfaces, including GPIO, UART, SPI, I2C, USB, etc., facilitating rapid development and debugging for developers.It's worth noting that the entire LuckFox Pico series development boards support both buildroot and Ubuntu 22.04 systems, allowing developers to choose the appropriate system based on project requirements, providing greater flexibility to meet specific application needs.

With a single 10/100 ethernet port and no Wifi, "routing" appears to be a fairly theoretical scenario.

Modify the relevant device tree to set the USB mode to host mode, Can support USB WiFi

&usbdrd_dwc3 {    status = "okay";    dr_mode = "host";};

You can refer to it

I will gladly change my assessment accordingly, from theoretical to academic.

If you need to connect USB WiFi (and given that many USB WiFi doesn't work as AP nor supported under OpenWrt now), I don't see the point of using it as router.

Also you need Pro/Max variant to have 128-256MB ram, other variants only 64MB ram which is no good, the overall package here doesn't look good when compared to RPi Zero W/2W.

@xiaobo why are you stuck using that kernel version?

I very much welcome this!

Yes, OpenWrt is primarily about routers, and a single port device is not too convincing in that field.

However, OpenWrt is a very good and stable foundation for 24/7 running networked applicances in general, and for that the small Luckfox pico with wired Ethernet is a very interesting platform, for example in automation.

As I need customisation I already built openwrt from https://github.com/ticklab/openwrt/commits/rockchip-22.03/ but at the moment it is totally unclear to me how to transition from the factory provided linux to the openwrt setup produced by the build (openwrt-rockchip-cortexa7-luckfox_pico-max-squashfs-boot.img and openwrt-rockchip-cortexa7-luckfox_pico-max-squashfs-rootfs.img).

Is there any ongoing discussion about OpenWrt on the Luckfox Pico Max other than this, apparently stalled one? Any pointers welcome!

Yes, I use OpenWrt on several devices, that years ago ran Debian, but where Debian has become (way) too large.

Several NSLU, Seagate Dockstar, PogoPlugs and such are now nicely useable as USB-, UART-, ADB-, Sensors-, ... -to-Network bridges, POE-powered.
