SATA on TWR-LS1021A

artsiomstaliaro — Tue, 28 Apr 2015 19:37:28 GMT

Hello,

Im trying to start SATA 3.0 on TWR-LS1021A with external hard driver. But u-boot and Linux cannot detect it.

Maybe anybody has experience with SATA on LS1021A?

Maybe somebody has RCW especially for SATA?

Hi Art,

have you downloaded and applied service pack for SDK 1.7?

Freescale Linux QorIQ SDK v1.7 for LS1021A SP v1.5

Br, Klemen

Hi Art,

as I wrote in first post, you need to apply SP 1.5 to add support for SATA.

Hello Art Staliarou,

Please download LS1021A SP v1.5 from QorIQ LS1 Tower System Module|Freescale, and apply this patch based on SDK 1.7 release, this release includes Linux SATA driver. SATA driver is enabled by default in V1.5 release, you could use the pre-built images to do verification.

In addition, please enable SATA in RCW, please refer to the following worked u-boot log.

Thank you!

i was apply the patch (SP v.1.5) and saw that SATA driver was not included in Linux build configuration (Freescale 3.0Gbps SATA support). I was add it and got next errors when compile:

Thank you for idea about "In addition, please enable SATA in RCW, please refer to the following worked u-boot log.".

This is true, need to enable SerDes 1 PLL 2.
