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.

Hi Anirudha
for new board or memory it is necessary to follow steps described in
Chapter 4 How to bring up a new MX8MSCALE board MSCALE_DDR_Tool_User_Guide.pdf
included in package
i.MX8 MSCALE SERIES DDR Tool Release (V2.10)
use latest uboot
imx8mq_evk\freescale\board - uboot-imx - i.MX U-Boot
