Linux/am5728: SATA gen3 doesn't work

Ilya Kravchuk

Part Number: AM5728

Tool/software: Linux

I'm trying to connect Micron 550 mSATA SSD to the am5728 evm. I've configured Linux kernel, how it describes here, but after booting there is no any detected block device.
lsmod indicate, that libahci_platform, libahci, libata modules are inserted, but there is no sata_ti.ko, and I can't find it in the xconfig search, is it normal?

Hi,

Just FYI, there is the following known issue:
LCPD-7300 P3-Medium SATA modular tests failed Connectivity am57xx-evm

See the release notes:
processors.wiki.ti.com/.../Processor_SDK_Linux_Kernel_Release_Notes

Also the guide you've followed states:

"The SATA driver supports following features

Gen-1 & Gen-2 SATA HDD/SDD
Hotplug"

Also note the Features NOT Supported section:
"Features NOT supported
Following features are not supported currently:
Gen-3 SATA HDD/SSD is not guaranteed to be supported on OMAP5 and DRA7 due to a silicon bug which prevents correct PHY speed negotiation."

Make sure you comply with the above listed details (the device you use is not gen3).

Best Regards,
Yordan
