IMX8MP Custome board DDR Calibration failed

[leavs]

We designed one board based on IMX8MP EVK, we use 2GB LPDDR4, When I use Mscale DDR Tool to Calibration it, I got the following FAILED error.

PMU: Error: Failed write leveling coarse
PMU: ***** Assertion Error - terminating *****
[Result] FAILED

Can you help to check what will cause this?

I use MT53D512M32D2DS-053 WT:D and I will attahce the script file for you to check.

The whole result like follow,

Thank you for the help, the issue comes from the hardware, we use one new DDR to resolve this issue.

Hi @leavs 

I hope you are doing well.

Please try changing PhyVref to 0x11.

Could you please provide me with the RPA xlsx sheet and schematic?

It will help to debug & cross-check information about lpddr.

Thanks & Regards,

Sanket Parekh

Hi @Sanket_Parekh 

Thanks for your quickly reply.

I attached the schematic for LPDDR4 and RPA xlsx sheet.

We use same designe with IMX8MP for LPDDR4, but we use another Micro DDR called MT53D512M32D2DS-053 WT:D, it only have 2GB. 

I will try changing PhyVref to 0x11 and back with the result.

Hi @Sanket_Parekh 

I changed PhyVref to 0x11, the same error and result. Is there other option I can try?
