Hollow.

The following is the learning cycle enumerated by  the users guide of BQ27520EVM. These questions are also referenced in another document  SLUA903–July 2018 - 

Achieving The Successful Learning Cycle。

The original steps are listed on the left side and the question is on the right side:

### (5A-5B) 1. Start with a discharged,                  ---> Q1: Just connect the battery and discharge without any other steps?
relaxed battery                                                        ---> Q2:  I should verify control status : RUP_DIS、VOK = 0  after relaxed step ?
2. Run IT_ENABLE command from                        ---> Q3: After I click IT ENABLE,  I should verify Bit  QEN  = 1 . wether Update status0  == 0x04 is needed? 
the commands window
3. Charge cell to full capacity                                 ---> Q4: In this step ,should i verify FLAG  FC =1 ?           
                                                                               ---> Q5: Is it necessary to add a relaxation step here? 
4. Discharge at C/5                                                
                                                                               ---> Q6: Is it necessary to add a relaxation step here?                               
5. Check to see that
UPDATE_STATUS data flash                                ---> Q7:Is  Update status0 in [ Data Memerory ->Gas Guaging -> State] only change once is this step?
value is 2

###(5C1) Write Ra Table, Qmax, Cycle Count and Update Status to gauge    ---> Q8:Is this operation done automatically by the BQStudio ? what should i do ?

###(5C2) Reset Gauge                                         ---> Q9: Click RESET button in BQStudio，Are there any other flags I need to verify？How can I know if the                                                                                                  learning cycle is complete successfully ？

###(5C3) Read flash, save golden .SREC,.BQFS, and .DFFS files   --->  Q10:Is the only thing I need to do at this step is to click the “ Create Image Files”                                                                                                                                button  in Golden Image ? 

I'm so sorry I have so many questions about this, but in order to complete the whole battery calibration, I have to figure out every aspect of it. Is there anything missing in the above understanding of the entire process? If yes, Could you please also point out ? Thank you for your patience and look forward to your reply as soon as possible. Thank you !
