[Sipeed LicheeRV 86 Panel Review] + Unboxing and Lighting

I am really happy to get the board. Here is the picture:

The USB marked USB-UART is connected to the computer (after this connection, a serial port will appear on the computer, and you can connect and control it with putty): front and back:

Use putty 115200, n, 8, 1 flow control is not selected. A MaixLinux appears, which seems to be Allwinner's own customized Linux

The screen is a capacitive screen. The program above can directly set the WiFi name and password. After entering it, just press connect.

There is another fun thing, it can light up! But the LED on the core board of this 86 kit is mixed with other parts, so it is not directly

The serial port cannot be operated (no light). What should I do?

Unplug the core board and play ! But there is a new problem. How to operate the Linux of the core board without a serial port ?

ADB !!! The USB port of the core board is used for ADB debugging and control . The img of the core board has actually installed ADB. You can debug as long as ADB is installed on Windows 10 or your Linux PC .

You can play without burning img! Of course, if you flash the core board and burn img yourself, remember: tina_d1-lichee_rv_uart0 can also be used

img production tool: PhoenixCard. You can use it just by unzipping it.

Installation of window10 ADB tool : download platform-tools_r33.0.0-windows and unzip it

Copy the directory platform-tools to the C drive , and then add the path to the path in the system environment variable:

Then you can enter ADB version in the Windows command line: to confirm whether it is installed:

At this time we can enter ADB shell to start connecting to the core board:

echo 65 > /sys/class/gpio/export

cd /sys/class/gpio/gpio65

echo out>direction

echo 1 > value

echo 0 > value

The light on the core board changed:

Okay, let’s play with it briefly first.

The next step is to prepare the cross-compilation environment, otherwise you still can't play with the code. OK, I'll stop here for now. Thank you.

ADB always feels like a set, it doesn't seem necessary for embedded development

The main reason is that this core board only leads to the USB interface, in order to facilitate control. This is the only way to play.
