iMX6Q DDR Stresstest

内存型号：IS43/46TR16XXXA型号

错误：低频135Mhz等会出现错误。如下：

DDR Stress Test Iteration 1
Current Temperature: 53
============================================

 

DDR Freq: 135 MHz
t0.1: data is addr test
Address of failure(step2): 0x10000000
Data was: 0x00000010
But pattern  should match address
Error: failed to run stress test!!!

 

        0x0        0x4        0x8        0xC
        ----------------------------------------------------------------------------------------------------------------
0x10000000:    0x00000010    
memory read is done

 

解决方法：先确保Column、Row、buswidth、Bank等参数均正确。通过官方提供的I.MX6DQSDL DDR3 Script Aid V0.10更正DDR工作频率，阅读datasheet调整tRC、tRAS、tRCD=tRP时序值。
