Anybody here??? I'm interested in the project… it would be nice if sfinktab write a tutorial for us and we can get this thing working… it's really sad to copy files across the network :(

Thx

If anyone is still here, I found the i2c bus:

On the My Book Live motherboard, chip U12 is not stuffed, but pins 7 and 8 are i2c data and clock respectively.
They seem to be 1.8v. It is running at 400khz I can access it from linux using /dev/i2c-0 directly.

Sfinktah,

Can you share with us the connections to make this work?
Please!

I see that D+ and D- balls (R1 and T1 in APM82181) are closest to the edge of chip.
These balls are at the right-top corner of chip on picture

img1182m.jpg (see link above in tomas's post)

Using thin wire or pin as a probe it's possible to check whether some of them is connected to pads of J4 or to some trace going from under the chip in this area.

Re: extend My Book Live with USB ports

Wed, 18 Jul 2012 06:43:40 +0000

Is anyone still here, or averyone give up? I'm really intersted in this project. And as I see all we need is D+ and D- and pray for internal oscillator for USB.
Because I still haven't my own unit for experiments I'll be pleased if someone will make more detailed photo of south-west side of APM82181_USB (according to tomas123 photo named img1182m.jpg)

Any updates on this?

Re: extend My Book Live with USB ports

Tue, 27 Sep 2011 13:54:07 +0000

Great, Tomás!

I'd be all over the hardware right now but, unfortunately, I believe I bricked my hard drive and now I'm forced to focus on getting it back online without losing my data.
Maybe the UART hack will help me with the unbricking, so that's a (partial) relief.

I'll post back when it's working again.
In the mean while… Good luck!

Disclaimer: I'm not an expert in linux whatsoever, but I don't consider myself a newbie either.

Re: extend My Book Live with USB ports

the chip allows for an internally generated reference clock source generated by the Peripheral/Ethernet PLL

wow, great hint
let us hack the linux kernel driver… ;-)

a link to a pdf with the usb hardware layout APM82181_USB.pdf
for the another hardware hackers in this forum
(see http://mybookworld.wikidot.com/wd-mybook-live-uart )

Re: extend My Book Live with USB ports

Wed, 31 Aug 2011 16:20:08 +0000

Tomas123,
I do have the pin layouts of the APM82181 from a project unrelated to WD. Although we ended up not using this chip, it exceeded our expectations so I believe WD made a great choice. I will PM them to you.
You are right about the crystal, that has to be 12.0 Mhz. But you can also use an external oscillator at 12, 24 or 48Mhz, and even better, the chip allows for an internally generated reference clock source generated by the Peripheral/Ethernet PLL when defined by one of the USB System Device Control Registers. So attaching a crystal is completely optional :-)
That should give you a better chance to succeed…

Re: extend My Book Live with USB ports

Fri, 26 Aug 2011 21:06:44 +0000

I posted all my infos in this thread (usb kernel module, APM82181)

a little step: we only need D+/D- and a level converter

we have not a data sheet with pin layout of APM82181
but I'm afraid that D+ / D- are not soldered
see my pitures here:

Hey Tomas123,
Are you still interested in adding an USB port to your MBL? I'd be very happy if we could actually pull this off and, as I see, there's no easy way to add it.
I'm an electric engineer and am offering my knowledge and experience to this project.

Please tell me if you'd be interested in this.

Re: extend My Book Live with USB ports

Sat, 14 May 2011 21:20:26 +0000

Yes, but it can give us some hints to write the debricking guide.
I will check if pressing the reset button during start does have an effect.
I hope that it runs the "fresh_install" of u-boot.

Re: extend My Book Live with USB ports

Tue, 10 May 2011 21:11:02 +0000

Yes, I read your detailed post last week.
There are some nice hints for usb support - but we have no solder pads for a usb plug …

thanks for information

Re: extend My Book Live with USB ports

Tue, 10 May 2011 11:25:10 +0000

Hi tomas123 I posted the U-boot output in the UART discussion.

I hope that you have fun with them.

Re: extend My Book Live with USB ports- Sata

Tue, 03 May 2011 12:21:03 +0000

there are no solder pads for a second Sata drive

Re: extend My Book Live with USB ports- Sata

Sun, 01 May 2011 14:46:35 +0000

Thomas123

That would be great if we can more easily add one or more Sata drives.

Don't you think ?

Re: extend My Book Live with USB ports

Fri, 29 Apr 2011 15:17:29 +0000

Great!
Can you post here the console messages while booting (U-boot etc) before the kernel logs the messages (dmesg)?

Re: extend My Book Live with USB ports

Fri, 29 Apr 2011 10:24:46 +0000

Hi tomas123,

Yes you are right the "J8" is a UART (Serial) port.

Details how to connect it are listed here: http://mybookworld.wikidot.com/wd-mybook-live-uart

I tested it with my Guruplug JTAG board.
http://www.globalscaletechnologies.com/p-28-guruplug-jtag.aspx

The "J4" could be a JTAG port to flash the u-boot of a bricked device.

Re: extend My Book Live with USB ports

Mon, 14 Mar 2011 15:35:55 +0000

Hi tomas123,

you did a great job to find out -unfortunately- that there is no (easy) way to add a USB.
(of course I would be interested as well.)

What do you think about the possibility of a 2nd SATA port ?

Best regards
copa017

Re: extend My Book Live with USB ports

Thu, 10 Mar 2011 20:01:41 +0000

just yesterday I disassembled my book live

Hi,

Could you explain how to disasembly the WD Live ? I can't find a way to open it with no damage to the box. Pictures would be great!

Thx

Re: extend My Book Live with USB ports

Wed, 09 Mar 2011 09:29:22 +0000

no comments / no ideas ?
Am I the only one who is interested in USB Ports?

The bane of WD.
The whitebook has an usb port but the usb kernel modules in the SDK are incompleted and we need a hardware workaround for simple usb 1.1 devices (a few usb switches can translate from 1 to 2 see http://mybookworld.wikidot.com/forum/t-225050/ ).

Now we have a great hardware with great SDK and a native compiler - but no USB :-(

Re: extend My Book Live with USB ports

Sat, 05 Mar 2011 17:57:24 +0000

I found a schematics for APM82181 (Bluestone Evaluation Board)
http://www.bilder-space.de/show_img.php?img=b25e7a-1299347537.png&size=original

there is a 4 pin usb otg connector ( http://en.wikipedia.org/wiki/USB_On-The-Go )
and the APM82181 need a 12Mhz crystal on pin USB_OTG_XTAL for powering usb (a standard usb crystal)

but there are only 2 crystals on board: 1x25Mhz and 1x50Mhz
… now we can give up.

Re: extend My Book Live with USB ports

Sat, 05 Mar 2011 17:28:44 +0000

You can initialize a usb handshake sequence with a pull-up resistor on usb-pin "D-"

ok, I checked with a pull-up all pins of connector J4 and empty places of IC U12 and U29
there was nothing to see on my oscilloscope and no message in dmesg log

we have no datasheet (with pin layout etc) of apm82181
http://www.apm.com/products/embedded/singlecore460/apm82181/
We are looking for a needle in a haystack.

Re: extend My Book Live with USB ports

Fri, 04 Mar 2011 21:11:21 +0000

I used an Oscilloscope and tested Tx with

echo "hallo" > /dev/ttyS0

the signal is inverted

I think, that usb support in the kernel comes from a predefined "make menuconfig" in the developer kit

Re: extend My Book Live with USB ports

Fri, 04 Mar 2011 17:21:52 +0000

how you detect that J8 is serial ?

what do you think about J4 ? There are a lot pins, is'it possible that USB linked to here or at least SPI / i2c? otherwise for me unclear for what reason USB support included to kernel?

Re: extend My Book Live with USB ports

Thu, 03 Mar 2011 22:20:31 +0000

bad news

the 4 pin connector J8 (left top)
http://www.smallnetbuilder.com/images/stories/nas/wd_mybook_live/wd_mybook_live_inside.jpg
is the serial console /dev/ttyS0

see picture above, there 4 pins from left to right: GND , Tx , unknown , Vcc=3,3V
(I think, that unknown is not Rx)

Re: extend My Book Live with USB ports

Tue, 01 Mar 2011 22:23:17 +0000

I was curious and bought a mybook live.
And you are right: This 4-pin usb-connector has GND, +3,3V, +3,3V and Vcc.
But Vcc is also 3,3V (connected with board voltage).
Datasheet: http://www.virtualpressoffice.com/JPContentAccessServlet?fileContentId=1000000010913&source=sd&showId=769
says, we need a USB-HUB (3,3V to 5V).
There is no USB-HUB on board.
I never heard of a developer usb port ;-)

lets try it

I'm unfortunately a little expert for white light usb support and usb kernel modules
see my long trouble thread with bleep and andrew_sh here:
http://mybookworld.wikidot.com/forum/t-225050/
there you can see some hints for debugging usb

for modules.usbmap see here:

please post a # ls -l /sbin/

you posted following file from sdk - are you sure that this is the kernel config file for mybook live ?

Re: extend My Book Live with USB ports

Thu, 10 Feb 2011 15:26:02 +0000

is following not enough

Sorry, I thought it was a fragment. I've never seen so few modules.

WD has a new concept. Here a listing from my My Book World Edition (white light) with dozen of kernel modules
http://pastebin.com/KPTSW5KM

I'm not expert to read kernel make file for static <-> loadable kernel module.
I think you must (cross-)compile a loadable ehci usb kernel module.

is
# cat /proc/modules
also empty? I'm afraid so ;-)

Re: extend My Book Live with USB ports

Thu, 10 Feb 2011 15:10:30 +0000

yep, drivers compiled into kernel
about "find /lib/modules/ -follow", is following not enough ?

in /lib/modules present just tcrypt.ko , scsi_wait_scan.ko , g_file_storage.ko

here http://pastebin.com/PCp8GrB4 as i understand default kernel config.

Re: extend My Book Live with USB ports

Thu, 10 Feb 2011 09:04:32 +0000

I reread your last message.
Do you mean WD compiled necessary device driver static into the kernel?

please list your module folder

busybox syntax

# find /lib/modules/ -follow

or gnu syntax

# find -L /lib/modules/

Re: extend My Book Live with USB ports

Wed, 09 Feb 2011 20:28:32 +0000

3.4V instead 5V on pin4 is a bad message for non self-powered devices

The sata disk need 3.3V / 5 V and 12V,. Therefore we have a 5V voltage inverter on board.
It could be that a cheap component for usb voltage (500mA) was not mounted on the PCB.

The output of lsmod can not be empty. lsmod is a wrapper for

# cat /proc/modules

try this and post the output here

in your dmesg I can't find loading the usb kernel modul
I think you must load the corresponding usb kernel module like here

# insmod /lib/modules/2.6.xyz/kernel/drivers/usb/host/ehci-hcd.ko

Re: extend My Book Live with USB ports

Wed, 09 Feb 2011 17:49:36 +0000

about voltages 0/3.4/3.4/3.4

Re: extend My Book Live with USB ports

Wed, 09 Feb 2011 17:00:21 +0000

3.7v is a bit to much for D+/D- but not enough for Vcc.

The host expects 0 V to 0.8 V for a Low level and 2 V to 3.6 V for a High level.
