Other Parts Discussed in Thread: PMP, DM385

Hi , TI's engenier:

I can find a issue in below linkage:

Features not supported,

Port Multiplier support has some issues when port 0 of port multiplier is used. Do not use port 0 of PM and connect devices to other ports in PM, OR hotplug devices after Linux is up. These are just workarounds.

But in below linkage have not the same description:

which linkage could been trust?

Thanks very much!

The second one (TI81XX) is up-to-date. This is the user guide we have inside the latest EZSDK / PSP :

ti-ezsdk_dm814x-evm_5_05_02_00/board-support/docs/TI81XX_PSP_User_Guide.pdf

You need to refer to http://processors.wiki.ti.com/index.php/TI81XX_PSP_User_Guide#SATA_Driver (corresponding to the 04.04.00.xx combined releases for DM814x/DM816x/DM385 platforms). The PMP port 0 issue was resolved in PSP 04.04.00.xx.

Pavel
