i.MX8MNano (m815S) DDR Register Programming Aid (RPA)

This is a detailed programming aid for the registers associated with i.MX 8MNano (m815S) DDR initialization.  For more details, refer to the main mScale DDR tools page:

Hi @jan_spurek ,

 

May you please indicate some details with respect to the second Frequency Point?

How is this handled by the DDR Stress test?

As far as I understand the tool only check the calibration around one frequency point since it only verifies against a typical DDR register setting.

Or just there for further helping validating the design at lower bus frequency with the vTSA tool?

 

Thanks and best regards

 

 

Hello @Rodrigue ,

in case of the mScale processors, the training is performed for each of the frequency points - there are separate register sets that hold the calibration values for each frequency.

Best Regards,

Jan
