IMX6S DDR3 x16-Databus and stress test

Question asked by Thomas Graf on Mar 6, 2014

Hello,

 

We made a custom design with the IMX6SOLO and only use a single DDR3 chip (MT41J64M16) connected with 16-Bit data bus.

Now we have some trouble to get stable DDR3-Access.

 

The DCD Data we use when booting from SPI-Flash is like in MX6SNW.txt. We can start u-boot and nearly boot to the linux prompt. But it crashes randomly. When the PCB is worm it is more stable.

Thus I suppose we need to calibrate DDR3 timing parameters.


Unfortunately the stresstest tool never returns any results after starting. The output is in stresstest.txt.

 

Any hints what might be wrong?
