Hi,

We need to verify PCIe eye-diagram on IMX6 DualLite, we refer "PCIe Certification Guide" (www.nxp.com/files/32bit/doc/app_note/AN4784.pdf) and found some problems.


1. About software setup, refer https://community.nxp.com/docs/DOC-94923

    This software patch & kernel config setting is too old, we can't apply it to Yocto-L3.14.38 BSP.

    Do you have new patch to modify "pic-imx6.c" for keep PCIe clock and power in the tests??

 

2. About hardware setup, do you have more detail document for us refer ??

    (like http://www.nxp.com/assets/documents/data/en/application-notes/AN5158.pdf)

 

Thanks,

Arthur
