I have a PCB with an MCIMX6S5EVM10AC that is not booting correctly and it seems like it's an issue with our DDR3 RAM. To verify this, I ran the DDR stress test tool V2.60 but found no issues. I also tried V2.30 with no issues. However, when I run V1.0.2 or V1.0.3 I consistently get the following error:
DDR Freq: 396 MHz
t0.1: data is addr test
t0: memcpy11 SSN test
t1: memcpy8 SSN test
Address of test1 failure: 0x2c022014
Data was: 0x00000024
But pattern was: 0x00000004
It also seems that V1.0.2 and V1.0.3 take significantly longer to run.
When I test a known good PCB, it passes the DDR stress test on V2.60, V2.30, V1.0.3, and V1.0.2.
Why are there differences between different versions of the stress tester? I would expect the results to be the same no matter what version I am running.
