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 

Best regards

Hi,

Thanks for response.

Can you please confirm if MT53D1024M32D4DT-053 WT:D is tested with iMX8M and the quad die is not issue.
