Hi all,

i am trying to do calibration of the i.mx6 32bit bus DDR3 RAM with 2 Chip Select using the DDR Stress Test tool

My calibration always return failed if i tried to calibrate both CS together (select from the selection that prompt in the DDR Stress Test tool)

If i calibrate CS0 only, it will success.


I come across this article:

Re: 32bit bus width memory with 2 cs in IMX6Q


I tried to modified the MDMISC[CALIB_PER_CS] bit in the .inc file, but how do i confirm whether it's calibrating CS0 or CS1?

Is this method applicable with using the DDR Stress Test tool?


Thank you.
