Edge-V: Domain: Power management - LiPo battery does not charge

[kenny]

sorry for late reply, this weekend i put 3 pcs Edge-V to test the same operation:

• when battery power low(0%, about 6.8V), Android will power off system to save power.
• After shutdown, the system will continue to discharge until the battery is protected(under 5.6V).
  • MCU normal status: about 8mA
  • open WOL: about 76 mA
• After battery protected, the battery no power output(0V), when other power supply plug in, battery will be reactivated again.
  
  
• could you help me to check:
  • Edge–V communicate with Juice board?
    • check CW2015CSAD i2c connect, if connect failed that will report error.
      i2cdump -f -y 8 0x62
      
    • check bq25703 i2c connect, if connect failed that will report error.
      i2cdump -f -y 8 0x6b
      
  • what is the battery voltage?(which battery can not power on)
  • no battery insert, what is the BAT_JACK voltage?(generally 8.51V)
    
    
    
  • no battery insert, what is the R20 voltage?
    
    
  • no battery insert, what is the R1 voltage?(depend on power supply, for mine is 12V)
    
    
  • with battery(which battery can power on) insert, no other power supply, what is the R1 voltage?
    
    

thank’s for your help
