Several shallow threads out there on the Sata ls1043ardb question.

 

From a previous thread:

 

>> it's posible run sata at LS1043ARDB. SATA serdes is multiplexing with PCIe. You only need is simple reduction from >> pcie connector to sata connector. Next step is change rcw to enable SATA and switch SW3[4] to 0 (100MHz clock). I >> work on LS1043ARDB with SATA without problems.

 

From another previous thread where the question was Sata on ls1043a:

 

>> This is not possible because SATA could be configured only on SerDes lane 3 (D), while mPCIe slot is connected to the lane 2 (C).

 

I have done some work in this area myself.    I have changed the rcw to 0x3358 (verified upon boot), and also set the Switch SW3[4] to 0.     It booted up fine, but no Sata.

 

I have a simple PCIE to msata board.    Pretty sure the board (have 2 of them) is fine.

 

At least need to know if the HW can do this, as I've already gone down a pretty deep rabbit hole.

 

Greatly appreciate any help.
