SATA Cable Connection with OMAP-L138 LCDK

Other Parts Discussed in Thread: OMAP-L138

Hello,

I'd like to communicate SSD through SATA. Usual SSD has 22-pin SATA connector.

However, there is only 7-pin SATA Conncetor in an OMAP-L138 LCDK.

If I connect SSD and LCDK board with 7pin to 22pin SATA Cable, do I share a power from provided 5V 3A adapter or use external adapter? If not, am I have to use a SMPS to share the power both SSD and LCDK?

As shown in first image, there are three different power, 3.3 V, 5 V, and 12 V. If I use properly, am I have to connect all?

Finally, I found 7 pin to 22 pin SATA cable below.

Is it OK to Communicate?

Thank you. :)

Hi user4566427,
You should use external SMPS where you can use the power for SATA harddisk and take out the SATA cable from disk and connect to LCDK SATA connector.
This is sufficient, the grounding will be proper between SMPS and SATA hard disk.
I have already connected like this and able to detect the harddisk in LCDK board.

Thank you for your rapid reply. :) But I can't exactly understand because of my poor English level...

So, you mean LCDK board connect provided AC/DC Adopter and SSD connect externel SMPS?

Hi user4566427,

In your first picture, the Harddisk has Power and Data connection interface....right? . Connect the power interface to the SMPS and connect the data interface to the LCDK board thorugh SATA. The SMPS will get power of 230V.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
