Testing custom SOM layout of IMX8M Mini with LPDDR4.  The calibration routine fails at step 1.  I am wondering what kind of hardware problem this would tend to indicate.  The DDR Tool fails calibration with the following output:

 

*************************************************************************
ARM clock(CA53) rate: 1200MHz
DDR Clock: 1500MHz

============================================
DDR configuration
DDR type is LPDDR4
Data width: 32, bank num: 8
Row size: 16, col size: 10
One chip select is used
Number of DDR controllers used on the SoC: 1
Density per chip select: 2048MB
Density per controller is: 2048MB
Total density detected on the board is: 2048MB
============================================

MX8M-mini: Cortex-A53 is found
