I’ve browsed the forum for information, I’m reopening the subject, I consider that the answers given are not acceptable.
The SoC/SOM is sold with the SATA functionality, see TRM. The SATA controller can pilot an SSD device directly through the UPHY10 universal interface.
When customers buy a SOM to place on their custom carrier boards, they expect to be able to do as the TRM says they can, so yes we should be able to make a carrier board design using UPHY10 and a mechanical SATA 7-pins port to connect an SSD, and yes we should have the support of NVidia if problem arise when doing so.
Having for answers: “sorry we have never validated the SoC SATA controller” or “you need to use a PCIe-2-SATA bridge like is done on the devkit” (BTW, try to buy the Marvell bridge from a reliable and well known supplier and you’ll have fun, real customers doing real production do not buy from amazon or ali express or chinese websites) or “we will not help you in this matter” IS JUST NOT ACCEPTABLE.
Please point us to a document or else that shows the SATA controller of the SoC has been validated (I’m sure there is one, you cannot sell a SoC/SOM with this marketed feature if it does not work as specified, otherwise this becomes a legal matter), and explains the requirements/process to follow at L4T level.
