Our processor is DRA74X with PMIC-659038, and use 3.02.00.03 SDK version.
Most of time, SATA device(Apacer APM2T42SM23008GTN-2ATMW) will mounted by system automatically after boot up, and the result of "lsblk" as below(SATA is mounted at /run/media/sda1)
But sometimes mount fail, so i can't see any result at "MOUNTPOINT", and if i try to mount it manually, will got some error message as below
