How to calibrate IMX8MP with 2000MHz clock frequency?

[abhiroopnray]

Hello,

I am using one custom IMX8MP board. The board is getting successfully calibrated with 800MHz and 1200MHz DDR4 clock frequency. I am trying to calibrate it with 2000MHz but while DDR stress test it is failing as data mis-match between read and write.

I have updated the DDR Stress test tab in the RPA as below:

memory set

0x30360054

32

0xFA031

Still it is not working. Can you please let me know how to resolve this issue?

DDR4 couldn't support 2000Mhz, only lpddr4 does

Hi Joanxie,

I am sorry for the typo, but we are using lpddr4.
