DDR Stress Test v1.0.3 vs. v2.20

Hi community,

 

there are some threads about this topic but I could not find a solution yet.

My DDR3 init script seems to work with the "old" DDR Stress Test tool. But when trying to use the current tool, "DQS gating calibration" fails. It seem to be due to the MR1 value which is not read from the init file correctly.

According to https://community.freescale.com/docs/DOC-105652#comment-31888 changing the last line setmem /32 0x021b001c = 0x00000000 of the Script-Aid generated script to setmem /32 0x021b001c = 0x00040000 should tell the new Stress Test tool to use a MR1 value of 4. But when looking at the output of the tool, it keeps saying "ddr_mr1=0x00000000".

 

Best regards,

Martin
