Hi Rence,
You can find the factory test and calibration files in our repository along with the driver: https://git.ti.com/cgit/tas2557sw-android/tas2557-ftc/

Hi Ivan ,
How to install Factory Test Application for generate a bin file "tas2557_cal.bin".
Is integrated this tas2557-ftc driver into the source code, then build in the Factory Test Application into android device after download the image?
e.g. kernel/msm-4.9/.../tas2557-ftc/ , or vendor/.../tas2557-ftc/?
Thank you.

Hi Ivan ,
I implemented the driver: git.ti.com/.../ ,and executed successfully.
But when I adjust the volume(adjust ring volume via volume key), the value "DevA Re" will change.
The value of each test is different (as shown in the picture).
I think the value should be not change on the same device.
How to judge whether the calibration data is correct?
Thank you

Hi Ivan ,
The ring volume in Settings/Sound/Ring volume.
Now the value range of DevA Re is not large after we adjust the tas2557evm_aacspk_a.ftcfg. (8.28~9.27 ohm ==> 7.35~7.37 ohm)
But I find a new issue, tas2557 driver can not find the TAS2557 calibration files ,error msg as below:
12031 06-17 11:43:11.667 0 0 I tas2557 6-004c: TAS2557 calibration file = data/tas2557_cal.bin, handle = -13 12033 06-17 11:43:11.667 0 0 E tas2557 6-004c: TAS2557 cannot open calibration file: data/tas2557_cal.bin 12035 06-17 11:43:11.667 0 0 E tas2557 6-004c: Calibration 0 doesn't exist
And we are sure that the files exist in device.
Please help us to clarify the issue.
Thank you.
