SATA on logipi

Does anyone know of a reference design that uses the logipi sata connector? I do not need the complete protocol, All I want is to plug two boards together and have them exchange data over a serdes link.

    We were prototyping an LVDS camera using the sata connector of the LOGI boards.  I will see if @jpiat can provide the reference code.

    Hi,

    we prototyped the interface between the logi-boards (pi and bone) and an MT9V034 camera sensor from Aptina and the communication was using LVDS at 300Mb/s. The interface was simplex (only data from camera to logi)  and synchronous (one LVDS pair carried the clock). The code is here  :

    Another good starting point to work on your example would be :

    http://hamsterworks.co.nz/mediawiki/index.php/High_Speed_Link

    where Hamster demonstrate communication between two FPGA board (spartan 3 based) using a custom core for asynchronous communication. This example could be improved by using the SERDES of the spartan6.

    Regards,
