TS-TPC-7990 SATA

Note:

SATA is functional on Rev. B or newer PCBs.

SATA is located on the mini PCIe header on the TS-7990. This is intended to be used with mSATA style drives to provide fast embedded storage.

The i.MX6 Quad and Dual include integrated SATA II support. This interface has been tested to provide 135MiB/s write, and 170MiB/s read in sequential accesses. In linux this is accessed through the /dev/sda device:

U-Boot includes a script to boot off of a SATA drive. The SATA drive should be formatted just like the SD card examples. In U-Boot run:

env set bootcmd 'run sataboot;'
env save

This will ignore the SD boot jumper and boot directly to SATA.
