imx6 mass production memory calibration

[yairh]

Hi, 

After reviewing  the information in

https://freescale.jiveon.com/docs/DOC-105652

https://freescale.jiveon.com/docs/DOC-346065 

We still would like to know how to run memory calibration for mass production purposes. 

It seems the the the UI version cannot be executed in "batch mode" generating calibration parameters after each cycle. The two other option described in https://freescale.jiveon.com/docs/DOC-105652 are used fro memory stress test and not generation of calibration parameters. 

Is there a way to generate calibration parameters in a non-interactive mode? We would like to run the calibration on a large sample of our product. 

Thanks,

Yair

Hello,

   Generally section 7.3 (Timing Calibrations Usage) of AN4467 (i.MX 6 Series DDR Calibration)
describes possible calibration policies.

https://www.nxp.com/docs/en/application-note/AN4467.pdf

  Usually it is enough to calibrate manually several boards from a batch under different
operation conditions and use average / median values for all boards.

  We do not have special calibration tool as You need.

Regards,
Yuri.
