OMAPl138 Read or write data to SSD by Sata

Alexander Romanovskiy

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

Hello,

I want to write or read data on SSD disk using Sata on LCDK.

1. I found some examples in spruh77a.pdf (29.3.3 and 29.3.4), but I don't understand where can I found any libs with functions used in this examples.

2. I found nothing intersting about Sata at Omal138 StarterWare.

3. I found examples in BSL, but it can only initialize sata and spin it up.

p.s.

Is there any differences between writing data to SSD or HDD disk?

Regards

Alexander Romanovskiy,

Download the Linux SDK for OMAP-L138 LCDK, find the SATA driver code at Linux Kernel 3.1.10
In addition that, refer the OMAPL138 BIOSPSP for SATA driver and Sample applications.

Go to LogicPD's web site. Click on the Kit Contents tab, at the bottom of the page click at:
OMAP-L138 SOM-M1 GEL, CCS Setup, & BSL Files - you will need to create an account in their website if you do not have one already and download the files.
The basic sata example will be at:
