extern 2.5" HD with beaglebone

My Beaglbone is powered with a mains adaptor not via USB.

But nothing happens...the HD is not spinning up.

I am using Robert Nelsons kernel and GENTOO.

Do I miss something or is this simply something the Beagleboard
cant do?

By the way: The HD comes with a simple cable -- not those Y-cables...

What do I wrong here?

Do you have a Y-cable around?

The USB supply on the Beaglebone is not capable of powering a 2.5" HD unless it only consumes 500mA.

Gerald

Meino_Cramer · November 7, 2012, 7:48pm

See below...thats why it comes without an Y-cable but with a simple
one.

Can I assume it it the same 5V as what powers the board and that the grounds are common?

Hi Robert,

thanks for your reply.

dmesg says nothing...

And: No, I havent an Y-cable...this is my first and only
external "pocket" HD-drive...

Best regards,

Meino_Cramer · November 7, 2012, 7:55pm

Hi Gerald,

the only electrical connection is between the HD-drive and the
beaglebone with a simple USB-cable (no Y-cable).

Since there is only one ground, it is common to both as far as the
beaglebone is soldered correctly.

I am concerned that it actually takes more than 400mA when the motors spin up. I am not sure if there is an over current condition that the kernel will detect it. You should see some sort of message if the HD is powered on. If you have an LED on the HD that shows power, then it is getting power.

Hi Robert,

thanks for your reply.

dmesg says nothing...

That's odd.. Would have at-least expected a usb detected message..

Did you modify the "defconfig"?

This 2.5 usb/ata is externally powered and used as the rootfs on this
beaglebone...

I’m working with SSD and conventional hard drives and all the problems I have had were related to the way I powered the hard drives.
If the beaglebone/beagleboard/etc can’t propertly power the hard drives (or other devices) they will fail.
In the case of the beagleboard we have had to power it with a 2.6A power source since we connected a wifi card, a hard disk, a camera, and a usb to serial converter.
Some time before we were using a 2.0A power source and we experienced usb subsystem hangs, hard disk errors, wifi errors, etc.
While the beagleboard is not usually consuming more than 1.5A sometimes devices have consumption peaks.

If you are experiencing this kind of problems it is recommendable you to connect the hard disk to the beaglebone through a 2.0A powered hub and test.
This way you will see whether you have a hardware or a software problem.

Hi Robert,

It seems I also have an issue similar to this one with the latest (3.2.33-psp26) kernel.
Earlier I was using your 19th of Oct. released image wich comes with 3.2.32-psp25 kernel and the USB host port works fine with it.
Then I wanted to add/change some I2C and SPI related settings and I compiled the currently available latest source (3.2.33-psp26), but with this kernel the USB host port is totally dead. It seems it do not detects if any kind of device is attached to the port (I tried a hub and a pendrive, so there cannot be a power issue). The drvvbus signal is not raised by the controller, so the power switch do not provides the 5V for the port.
I diffed the two kernel configuration files, but there was no USB related difference.
If you think I can attach these files for reference later, when I get home.

Thanks for your kind help in advance.

Best regards,
Laszlo

Yeah, i'd like to see what you changed.. As the bone's in my
regression farm are still active, running off usb based harddrives..
Although they all have external power.. I have not tried any bus
powered devices so i'll give that a go in a few minutes..

Hi Robert,

Please find attached the config files.
The 3.2.32-psp25 comes from /proc/config.gz on your latest demo image.
The 3.2.33-psp26 is my trial.

Thanks and regards,
Laszlo

Your 3.2.33-psp26 builds/runs/ and works with my usb flash drive just
fine.. So it's not the config..

gcc cross compiler used: arm-linux-gnueabi-gcc (Linaro GCC
4.6-2012.08) 4.6.4 20120731 (prerelease)

Hi,

thank you all for all the responses!

Finally I got something in dmesg: The harddisk was pulling to much
current from the USB port...desplite teh fact, that the specs (see
below) said "400 mA max." and the USB port is able to deliver 500mA.

Best regards,
mcc
