GG import with errors

Dariusz Witek
Prodigy 90 points
Other Parts Discussed in Thread: BQ20Z75-V180, BQEVSW, BQ20Z75-V160, BQ27541-G1

Hello,

I use bq20z75-v180 with EVSW bq20z75 v1.81.

After setting values in DF to appropriate and calibration, I exported DF to GG file. When I import the GG file to load data to another bq, I receive message four times: "The value you entered is not allowed because it results in code(decimal) 11 Division by zero". As I see four values are set to zero in EVSW after I imported gg file: CC Gain, CC Delta, CC offset, Board Offset. In GG file all the values are not zero.

Why there are these errors? How to solve this problem? GG file attached.

Waiting for your answer.

    Dariusz, 

    I reviewed your .gg file and did not see any corruption issues. I did notice that the CycleCount has not been set to 0 and the UpdateStatus has not been set to 2. You should incorporate these changes, if the .gg file is used to create a golden file. I also noticed that several of the 'time" values have been set to zero, which will disable the feature. I am not sure whether you intended to set it up this way. Finally, I noticed that the bqEVSW Version was not the latest update. Could you try downloading the software again from the bq20z85 website to see if this helps?


    Regards

    Hello Tom,

    Thank you for quick answer and valuable remarks. Documentation TRM says, in "time x" description, that the function is disabled when the time is set to zero. Intuitively I thought that the only time function is disabled (reaction on threshold without time delay) but in practise I see that the related threshold is disabled - I suggest the documentation would be more intuitive.

    The website bq20z85 as well as the product doesn't exist - please paste appropriate link to take the software from.

    Best Regards,

    Darek

    Darek,

    That was a typo. The software is on the bq20z75 website.

    Tom,

    I'm really happy that I can at last find the software on bq20z75 website. I don't see there TRM document so it's still not perfect.

    After instalation of the new EVSW 0.9.79, the message "divide by zero" still occures and additionally two other massages: "Missing value: IT Cfg (Gas Gauging) Ra Filter" and "Missing value: IT Cfg (Gas Gauging) Ra Max Delta". I used the same gg file and the previous varsion EVSW I had was 0.9.59.

    Well, it seems it's a bit worse with the new EVSW.

    Regards,

    Darek

    Darek,

    I imported your .gg file into an EVM and it reported that there was an invalid field. The Manuf Date field does not have the proper format. I corrected this an was able to load the .gg file without any errors. Are you using one of our EVMs?

    Also, the TRM for the bq20z75 is located on the bq20z75-V160 website. The TRM updates for the V181 firmware release is located on the bq20z75-V180 website.


    Regards

    There still seems to be a bug with importing .gg-Files.

    I am using the bq Evaluation Software Version 0.9.92 with a bq27541-G1. If I export a .gg-File, all values seem to be allright, but when I import a .gg-file, the calibration values are wrong by a factor 1000 (for example, CC Offset = -7.123 becomes -7123).

    I attached an example .gg-file (from a currently running learning cycle).

    Anyone encountering a similar issue?

    Regards,

    Daniel

    The firmware actually prevents manual writing to CC Offset. Only the device is able to update it. CC Offset is different from device to device and will actually auto correct at entrance to sleep if there is no I2C communication.

    Okay, thanks, but ALL the Calibration Data Entries are imported wrong, also CC Gain, CC Delta and Board Offset.

    Which tool are you using for importing the data, EVSW or Gauge Studio? Are you selecting 'Write All' or 'Write All, Preserve'? I recommend using Gauge Studio if you aren't already.

    Thank you, with the current Gauge Studio importing of .gg-files seems to works flawlessly, problems only occured in the EVSW. But I don't like the fact, that Data Flash Contents are directly written to the device after file import without giving the user the ability to check the values beforehand. Also, there is no option to preserve calibration values anymore, right?

    Although the Gauge Studio works great for most functions, there are some important features missing - that is why we still have to use EVSW an bqCONFIG:

    • autocycle option (at least an option for controlling the load circuit through EV2300 would be nice)
    • question based gauge configuration

    Are there any plans to integrate these features soon? Because at the moment it is quite "inconvenient" having to use 3 differnt programs for gauge configuration, calibration and learning cycle.

    Regards,

    Daniel

    A comment from the "side line" -

    - Regarding problems importing gg files with errors  in the calibration constants - please notice that regional settings on the computer other than English - US might cause the problems. I have been experienced the same problem but problem was solved once I changed the regional setting from Norwegian to Englich - US.

    Best regards

    Do I have to switch from German to Norwegian first? Just kidding ;-)

    Did not try your solution yet but it sounds very reasonable. Gauge Studio, fortunately, does not have this bug.
