Can vold support sata?

lqll — Tue, 01 Mar 2016 07:53:58 GMT

Hi community:

My environment is i.mx6q and android 4.4.2.

I mount sata in init.freescale.rc,like below:

# mount ext4 partitions

mount_all /fstab.freescale

mount ext4 /dev/block/sda1 /mnt/media_rw/sata

And boot log shows my sata is ready,like below:

ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

ata1.00: ATA-8: ST500LT012-1DG142, 0001SDM1, max UDMA/133

ata1.00: 976773168 sectors, multi 16: LBA48 NCQ (depth 31/32)

ata1.00: configured for UDMA/133

scsi 0:0:0:0: Direct-Access ATA ST500LT012-1DG14 0001 PQ: 0 ANSI: 5

sd 0:0:0:0: [sda] 976773168 512-byte logical blocks: (500 GB/465 GiB)

sd 0:0:0:0: [sda] 4096-byte physical blocks

sd 0:0:0:0: [sda] Write Protect is off

sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00

sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA

And I can read/write my sata hard driver.

But I get nothing in /dev/block/vold.

I want to use MTP to read/write my sata hard driver,but because vold can't find sata,so I can't read/write my sata by MTP.

What Can I do?Please help me.

Thank You.

Hello Li,

In android system ,you can 't use SATA directly, but you can use it as a ext_sd card.

Attachment is on how to use SATA in android 2.3.7, very similar to android4.4.2 , so you can refer to it !

Regards,

Weidong

Hi Sun,

I follow the pdf you give me,change my fstab.freescale like below:

-/devices/platform/sdhci-esdhc-imx.2/mmc_host/mmc1 /mnt/media_rw/extsd vfat defaults voldmanaged=extsd:auto

+/devices/platform/ahci.0/host0 /mnt/media_rw/extsd ext4 defaults voldmanaged=extsd:auto

Then I can see SD card by MTP,but this file is empty.

Where is my wrong?

Thank You,

Qiulong Li
