Does DDR validation work with hardware rcw config?

Latest reply on Nov 28, 2017 by Frank LI

I run DDR validation on B4860QDS board and my customize board with hardware rcw config, both failed, below are the logs. And I have adjust DDR rate to 1600MT. I have two question:

1. I want to know if DDR validation must run with NOR rcw config or other correct rcw connfig. If not, how to fix the issue of scan timeout? What meaning is scan timeout?

2. If using normal rcw, uboot hang due to ddr config might not be optimized. Is that impact the test of DDRv?
