Getting Started with BPI-R4

Development

Basic Development

Prepare to develop

 * Prepare 8G/above TF card, USB-Serial cable, Ubuntu System
 * Using your USB-Serial cable(3.3V TTL,Baud=115200) Connect to debug console on BPI-R4
   G=GND;  RX=BPI-R4 input;  TX=BPI-R4 output
    

 * BPI-R4 bootstrap and device select Jumper Setting
    

  * Examples:

 1. All Jumper is "1", BPI-R4 will boot from SD card
    

 2. SW3-A is "0" and SW3-B is "1" , BPI-R4 will boot from SPI NAND
    

 3. SW3-A is "1" and SW3-B is "0" , BPI-R4 will boot from eMMC
    

 4. If the console said "system halt!", it means that the bootup storage does not cotain any OS

How to burn image to SD card

 A. Note: burn image to SD card on linux computer
   1.You could download latest image from our forum
   * Here is the example image link: 
 
   2.Install bpi-tools on your Ubuntu. If you can't access this URL or any other problems, please go to bpi-tools repo and install this tools manually.
   * apt-get install pv
   * curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
 
   3.After you download the image, insert your TF card into your Ubuntu
   * Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card
 
   4.After step 3, then you can insert your TF card into R3, and press power button to setup R3
 B. Note: burn image to SD card on windows computer
   1. Download the tools from the website:   https://sourceforge.net/projects/win32diskimager/
   2. Install the tools into Windows computer.
   3. flash image into SD card.
 
 C. Change Boot Jumper to boot from SD, Enable SD Card Device.

Accessories

1. 10G SFP Module

The SFP serdes speed of BPI-R4 is fixed at 10Gbps, so only SFP that support this can be used！

Usually the PIN6 of 10G SFP+ module is GND. After inserting the module, SFP_MOD_DEF0 will be pulled low, thereby turning on the SFP power supply.

Therefore, if this PIN of the module is not GND, 3.3V_SFP power will not be supplied!

10G SFP+ Copper Module

The temperature of this module is very high when used for a long time, It can reach 90℃ without a heat sink or cooling fan. Be careful to prevent burns!

Note:

Do not pull out this module once it is inserted, otherwise it will cause BPI-R4 to reboot.This phenomenon does not exist with other modules.

10G SFP+ Fibre Module

2. 4G/5G Module

• BPI-R4 supports 4G LTE EC25. Quectel RM500U-CN & RM520N-GL 5G Modules.
• If you want to use 5G on BPI-R4:

   1. Insert 5G dongle into USB3.0.
   2. Connect RG200U-CN to mini PCIe, connect SoC through USB2.0(speed limited).
   3. Make an RG200U-CN LGA adapter board and insert it into M.2 KEY M.

Note: The availability of 4G/5G depends on the local carrier frequency band.

3. SSD

• please insert one M2.KeyM SSD into M2.KeyM slot.
