SATA port multiplier supported?


#1

Hi,

I just got my Turris Omnia 2GB Wi-Fi. :slight_smile:

Does the mSATA-port support port multipliers?

According to the data-sheet the the Marvell Armada 385 supports SATA Port-Multipliers.

I added a mSATA->SATA adapter, which works fine with an SATA-SSD. When I loop in the Port-Multiplier (JMB575, E-SATA-> 5x SATA III), dmesg shows the following error messages:

Does anyone have an idea whatโ€™s going wrong here?

Thanx for any hint!
