i.MX8M Mini LPDDR4 dual vs single die support

The LPDDR4 we are currently using is coming EOL.

We currently use the MT53E256M32D2DS-053 WT:B and the nearest replacement is MT53E256M32D1KS-046 WT:L.

The main two differences are the speed grade and the number of dies (moving from 2 to 1 die).

What changes, if any, to the software may be required to support the new part (1 die instead of 2 and faster speed grade)?

Do we need to re-run the DDR Tool to generate a new bin file to be programmed in the LPDDR4 controller?

Hello,

Just to be safe on your design I would suggest running the DDR stress tool:

i.MX 8M Family DDR Tool Release 

This would help on getting configuration for your new DDR.

Best regards.
