lichee-pi-zero / licheepi-tree

An external tree for Licheepi Zero configuring with Buildroot. Use this repo if you need UART over USB port (official dont have that feature). also, if using this repo with daily update or another release of buildroot, it cant compile, 2020.02 work fine

licheepi-tree

External tree used to configure Buildroot for Lichee Pi Zero.

Main goals of this project:

• use audio, recording and play are enabled
• use Wi-Fi via ESP8089, driver is installed as kernel module and loaded on startup
• use console via Serial Gadget (by power cable)

Structure

1. board - Linux configuration, rootfs overlay, out-of-tree dts files and setup scripts.
2. configs - Buildroot config

Installation

1. Clone project next to Buildroot . i using buildroot 2020.02

   git clone https://github.com/korr237i/licheepi-tree.git

2. Initialize tree of licheepi zero (fish shell, in buildroot/)

   make licheepi_zero_defconfig
   
   

3. Initialize tree as external (fish shell, in buildroot/)

   make BR2_EXTERNAL=../licheepi-tree/ ../licheepi-tree/configs/licheepi.config

   You can check output/.br2-external.mk to see if external tree was initialized correctly.

4. Run make menuconfig to initialize Buildroot and merge config from external tree:

   support/kconfig/merge_config.sh .config ../licheepi-tree/configs/licheepi.config

5. Run make linux-menuconfig and save Linux configuration obtained from external tree.

6. Add esp8089 driver to kernel: in board/setup/, run ./kernel-add-esp8089.sh, and enable esp8089 package in Networking support / Wireless as kernel module.

7. Run make

8. Write image on disk (e.g. /dev/sdc/), in licheepi-tree/board/, run:

   ./target_load.sh "/dev/sdc"

   To update filesystem on remote working machine, in licheepi-tree/board/, run:

    ./target_load_remote.sh port_number hostname password
