Hi,

 

We have changed LPDDR4 part from MT53B512M32D2NP-062 WT:D to MT53D512M32D2DS-053 WT for iMX8M design.

 

We are getting below error log.

Can you share LPDDR4 settings with the new part as we suspect the LPDDR4 settings only.

 

We are trying the DDRtool in parallel for configurations but it would be helpful if you can share the settings for this as this new part is supported for iMX8M.
