[iMX6Q] No SDCLK for DDR3.

[chilwonna]

Hi,

I made a new board from SABRESDP_C5.

DDR3's configuration is  same with SABRESDP_C5.

But, I have a big problem about DDR3.

In DDR Stress Test Tool,

Address and Data lines is generated. But SDCLK is not.

I need a help. Please advise.

Hi chillwona

probably these traces are shorted or broken, may be recommended

to check layout. Also please check Chapter 8 Avoiding Board Bring-up Problems
