Re: [beagleboard] why eSATA in X-15?

In u-boot, “scsi scan” doesn’t show anything. even “scsi reset” doesn’t find 
any devices.

Yeah, that was what I was trying to do. When I saw the jumper settings, I 
though this was possible.

Oh, don't change the jumpers. The production x15's isn't going to have
them, only the am57xx evm's.

I've configured u-boot on the microSD to look at the drives like so:

usb : (search first 4 partitions) (usb enables scsi power rail in u-boot,
hence first)
scsi: (search first 4 partitions)
eMMC: (search first 8 partitions)
microSD: (search first 8 partitions)

To setup boot from sata, return the jumpers to eMMC/microsd

boot into debian

cd /opt/scripts/
git pull

WARNING only have sata or usb plugged in, not both.. (script is hardcoded
for /dev/sda)

cd /opt/scripts/tools/non-mmc-rootfs
sudo ./mv_rootfs_dev_sda.sh

reboot..

microSD/eMMC (u-boot) searches scsi and boots from it. ;)

Hi Robert,

I bought this cable and connected a 240GB SSD. I dd a 32GB SDCard image to the 
SSD. I can mount /dev/sda1 and see rootfs. I changed the jumpers to select SATA 
as shown the the quick start guide (J3 1-2, j4 2-3, j6 2-3) and removed the 
SDCard. After powering down, I push the power button (s1), I see the power led 
(D3) light for a few seconds and goes out. I see nothing on the console. I also 
tried setting the jumpers per the PCB legend (J3 2-3, J4 1.2 J6 2-3) and I get 
the same results.

Hi Robert,

Is the port on the X-15 eSATA or eSATAp [1]? The picture [2] says
eSATA, though since Gerald said USB 2 is also supported I guess it is
eSATAp.

If it is indeed an eSATAp port then the cable you suggested is the
best solution in my view because it provides power.
The follow-up question is how much power can the X-15 provide at 5 V
and at 12 V.

eSATA enclosures also usually double as an USB enclosure as well. While on

that can depend on the host controller as well.

Because that was the decision we made two years ago. Plain SATA is provided
on the expansion connectors as well if you want to design an expansion card
for it. The TI EVM has mSATA on the LCD board.

eSATA also provides an extra USB2.0 port.

[beagleboard] why eSATA in X-15?

[Taceant Omnes]

My home desktop PC has an eSATA port. A few months ago I wanted to buy
a hard disk for backup and could not find any at a reasonable price
with an eSATA port. I bought one with a USB3 port.

My question is why was eSATA interface chosen for the X-15? Why not plain SATA?
