bq27541-V200 difficulty in achieving a learning cycle

Milla,

I'm not clear on what you did, but after a successful learning cycle update status should be 0x06. See page 25 of the datasheet.

Also here's an app note on achieving a successful learning cycle.

Are you about to create a golden file? If so you can set cycle count to 0. Cycle count 36 means you cycled the cell 36 times or you started with a non-zero data flash setting for cycle count.

Use bqEVSW to connect to gauge then select "Data Flash" then select "Gas Gauging" tab. "Cycle Count" is in the far right table. Click "Read All" to read and display current gauge data flash setting. Change "Cycle Count" to 0 then hit "Enter" key on your keyboard. Click "Write All" to ensure all values are written to Flash memory.

What device are you using? Your post says bq27541-V200. Is that correct? bqStudio/Battery Management Studio should work the same unless your cell voltage is below Flash Update OK Voltage level, which prevents flash writes. There's also a cycle count parameter in "Configuration" that also needs to be updated.

Milla,
Make sure your device isn't sealed and is in full access mode. Try extracting a gg file, modify the cc count to 0 and then import and write all. That should work
thanks
