Getting Started
1. Essential Things
- ROCK Pi 4 Core and Fuhai board
- Power supply
- DC 12V/2A or higher adapter: the inside diameter of the plug is 2.5mm，the outer diameter of the plug is 5.5mm.The positive electrode of the DC plug is in the inside, and the negative pole is outside.
- USB to TTL serial cable
- Fuhai exports a dedicated serial console, which can access the low level debug message.
- USB Male A to Male C cable
- If you want write image to Fuhai from USB OTG port or use fastboot/adb commands, you need an USB Male A to Male C cable to connect Fuhai and PC.
2. Get System Image
3. Flash System Image
eMMC is on board. Now we introduce one method of install image to eMMC.
3.1. Method of installation on eMMC
3.1.1 Boot Fuhai to Maskrom mode
- Plug DC 12V Adapter to turn on the Green Power Led.
- Press and hold the Maskrom Key.
- Plug one USB Male A to Male C cable, which also connect to PC, to Type-C port. You would see Red LED is on, now the system boots
- Release Maskrom Key
3.1.2. Use rkdeveloptool to flash image
Please refer to USB OTG port.
4. Power on Fuhai
4.1. Method one
- Step 1: Plug in the DC 12V adapter and make sure the Green LED is on.
- Step 2: keep pressing Power key until Red LED is on.
4.2. Method two
- Step 1: Plug in the DC 12V adapter and make sure the Green LED is on.
- Step 2: Plug one USB Male A to Male C cable, which also connect to PC, to Type-C port. Make sure Red LED becomes red.
5. Access from the Host PC/Laptop
Option 1: Serial Console
See the serial console port.
The baud rate of serial console is 1500000(8N1). As for the serial tool setting, refer to Serial Console.
6. LED
Fuhai has Power LED and User LED.
- Power LED
- The steady Green LED on carrier board indicates that the DC 12V adapter is plugged in.
- The flashing Red LED on carrier board indicates that the carrier board is given power.
- User LED
- The flashing Green LED on SoM board indicates that kernel is running.
