Dear All,
I am trying to calibrate ddr3 setting for my customer board with 4pcs MT41K128M16JT-125IT. Firstly, Get ddr3 initial register value by I.MX6DQSDL DDR3 Script Aid V0.10.xlsx, but I don't know how to select "System ODT Setting(ohm)" at the last line of this sheet.
I can get the impedance of DQ/DQM/ADDR/CMD/CTL/CK/DQS from hardware engineer, but how to confirm "System ODT Setting(ohm)"?
By the way, my customer board is based on the SabreSD reference design.
Best Regard,
Richard
Hi Richard

(like ddr_stress_tester_vx.y\script\mx6dq\MX6Q_SabreSD_DDR3_1GB_64bit.inc)
i.MX6/7 DDR Stress Test Tool V2.50
