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![]()
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.
