+ Shopping list (pictures of this hardware is shown later):
+ </p>
+ <ul>
+ <li>
+ External SPI programmer: <b>BeagleBone Black</b> (rev. C)
+ is highly recommended. Sometimes referred to as 'BBB'.
+ </li>
+ <li>
+ Clip for connecting to the flash chip: <b>Pomona 5250</b>
+ (SOIC-8) or <b>Pomona 5250</b> (SOIC-16) is recommended
+ (<b>X200S and X200 Tablet users will need a soldering iron
+ instead</b>, because of the type of package the flash chip is
+ in on those machines).
+ </li>
+ <li>
+ <b>External 3.3V DC power supply</b>. The one used by this
+ author has the label HF100W-SF-3.3 on it, but any decent
+ supply will be fine. Some people use the 3.3V from an ATX
+ PSU for instance (the kind that you get on a typical
+ Intel/AMD desktop computer. 6A supply should be fine,
+ the one used by this author is 20A (it won't actually use
+ that, it's just what the PSU is capable of).
+ </li>
+ <li>
+ Dupont <b>jumper cables</b> (2.54mm / 0.1&quot; headers)
+ You should get male-male, male-female and female-female
+ cables in 10cm and 20cm sizes. Just get a load of them.
+ </li>
+ <li>
+ <b>Mini USB A-B cable</b> (the BeagleBone probably already comes
+ with one.)
+ </li>
+ <li>
+ <b>FTDI serial board</b>, for unbricking the BeagleBone if
+ necessary.
+ </li>
+ <li>
+ <b>5V DC power supply</b> (from wall outlet to the BeagleBone).
+ The BeagleBone can have power supplied via USB, but a
+ dedicated power supply is recommended.

+
+ <h2>Setting up the 3.3V DC PSU</h2>
+ <p>
+ With my PSU, first I had wire up the mains power cable. Any clover or kettle lead will do. Cut the end off (not the one
+ that goes in the wall, but the kettle/clover connector).
+ Strip the protection away by a decent length, then strip the wires inside so that a decent amount of
+ copper is shown. Then wire up earth/live/neutral. This will vary according to what country you live in
+ and/or the colour codes that your cable uses inside. <b>Make sure to get this right, as a botched job
+ could result in extreme damage to you and your surroundings. Here's what mine looks like after wiring up
+ the power cable: <a href="images/x200/psu_power.jpg">images/x200/psu_power.jpg</a> - also, make sure
+ that the plug (for the wall) has the correct fuse. In my case I had a 240V wall socket, and the device
+ says that it accepts 1.5A at that voltage, so I used the smallest fuse available (3A). For 110-120V the device
+ says it needs 2.8A.</b> Also, if yours looks like in the image linked above, make sure to wrap electrical tape (lots)
+ around it for safety. (otherwise, don't touch the terminals while the PSU is plugged in).
+ </p>
+ <p>
+ Now take a red and black 20cm female-female jumper lead, and cut one of the ends off. Strip away the bare copper by about 1 or
+ 1.5cm so you get this: <a href="images/x200/stripped_jumper_lead.jpg">images/x200/stripped_jumper_lead.jpg</a>.
+ </p>
+ <p>
+ Black goes on -V, red goes on +V. In my case, I removed those screws from my PSU like this:
+ <a href="images/x200/psu_screws_removed.jpg">images/x200/psu_screws_removed.jpg</a>. Then,
+ </p>
+ <p>
+ Then I twisted the exposed copper on the jumper leads (so that they don't fray), and wrapped each to one of the
+ screws each, around it near the head. I then screwed them in:
+ <a href="images/x200/psu_jumper_leads.jpg">images/x200/psu_jumper_leads.jpg</a>.
+ </p>
+ <p>
+ If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied,
+ continue reading...
+ </p>
+ <h2>Setting up the BBB</h2>
+ <p>
+ Your BBB will have an sshd with no password on root. Find it's IP address
+ (it will use DHCP by default) and set a root password. The steps below
+ are done while SSH'd into a BBB.
+ </p>
+ <p>
+ Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded.
+ <a href="images/x200/strap.jpg">images/x200/strap.jpg</a> shows how I earthed myself. This is to prevent you
+ from causing any ESD damage. The surface that you place components on should also be earthed/grounded.
+ (for this, I used a shielded ESD bag with a wire, copper exposed, attached from the bag to the exposed metal
+ part on a radiator, which was earthed - not professional, but it should work. see <a href="images/x200/mat.jpg">images/x200/mat.jpg</a>).
+ Most people ignore this advice and don't ground/earth themselves, at their own risk. You should also store the BBB
+ in a shielded anti-static bag when you are finished with it.
+ (the principles above apply to any computer components, since they are extremely sensitive te ESD).
+ </p>
+ <p>
+ These instructions may or may not work for you. They are simply the steps that this author took.
+ </p>
+ <p>
+ setting up SPIDEV on the BBB: <a href="http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0">http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0</a>
+ - If you only setup SPI0, you don't have to disable the HDMI out. (you only need one).
+ That guide is for seting up the device overlay for SPIDEV, last part is to make it persist across reboots.
+ Needed to turn the BBB into an SPI flasher.
+ </p>
+ <p>
+ Don't bother modifying uEnv.txt. it won't work;
+ use the workaround here instead: <a href="http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes">http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes</a>.
+ </p>
+ <p>
+ Follow the instructions at <a href="http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0">http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0</a>
+ up to (and excluding) the point where it tells you to modify uEnv.txt
+ </p>
+ <p>
+ You need to update the software on the BBB first. Before being able to use apt-get,
+ I had to use the workaround defined <a href="https://groups.google.com/forum/?_escaped_fragment_=msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ#!msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ">here</a>:<br/>

+
+ <p>
+ Now test flashrom:<br/>
+ # <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512</b><br/>
+ Output:
+ </p>
+<pre>
+Calibrating delay loop... OK.
+No EEPROM/flash device found.
+Note: flashrom can never write if the flash chip isn't found automatically.
+</pre>
+
+ <p>
+ This means that it's working (the clip isn't connected to any flash chip,
+ so the error is fine).

+ </p>
+ <p>
+ if you need to extend the 3.3v psu leads, just use the same colour M-F leads, <b>but</b> keep all other

+ </p>
+
+ <p>
+ <a href="images/x200/5252_bbb0.jpg">images/x200/5252_bbb0.jpg</a> and

+ 5252 before being connected to the flash chip on the X200.
+ </p>
+
+ <p>
+ That's basically it. Now refer back to the documentation for how to use this on your board.

<p>
- At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):<br/>
- <a href="http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts">http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts</a>.<br/>
- Correlating with the following information, I was able to wire up my pirate correctly:<br/>
- <a href="http://flashrom.org/Bus_Pirate#Connections">http://flashrom.org/Bus_Pirate#Connections</a><br/>
- And by following that advice:<br/>
- <a href="http://www.coreboot.org/Board:lenovo/x60/Installation#Howto">http://www.coreboot.org/Board:lenovo/x60/Installation#Howto</a>.<br/>
- (it says X60 but instructions are virtually the same for the T60, with except to physical differences in how to disassemble the machine)<br/>
- Note: that last page says to wire up only those 5 pins (see below) like that: 1, 2, 4, 5, 6.<br/>
- Note: and then, for power it says (on that coreboot.org page) to connect the power jack to the board and connect the
- AC adapter (without powering on the board).<br/>
- Note: I ignored that advice, and wired up all 8 pins. And it worked.<br/>
-
- Here is the pinout (correlate it with your programmer's documentation):<br/>
- <img src="../images/t60_dev/0030.JPG" alt="" />

-
- <p>
- Connecting the pomona:<br/>

- </p>
-
- <p>
- Programmer has power:<br/>
- <img src="../images/t60_dev/0036.JPG" alt="" />
+ Connect the pomona from the BBB to the flash chip. No pics unfortunately. (use the text diagram above).
</p>
<p>
- Now flash the bricked machine using the 2nd computer. in my case I did:<br/>
- <b>flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/t60/libreboot_usqwerty.rom</b><br/>
- Note: there are also other ROM images for T60<br/>
- Note: this is using buspirate as the programmer, so it is flashing the T60, not the 2nd computer!<br/>
- Here's my terminal window on the 2nd computer (also the programmer is active):<br/>
- <img src="../images/t60_dev/0037.JPG" alt="" /> <img src="../images/t60_dev/0038.JPG" alt="" /><br/>
- So, you should see the following:<br/>
- --

- --<br/>
- At the end it says "VERIFIED", which means that the procedure worked. If you see this, it means

- <ul>
- <li>
- External SPI programmer: <b>BeagleBone Black</b> (rev. C)
- is highly recommended. Sometimes referred to as 'BBB'.
- </li>
- <li>
- Clip for connecting to the flash chip: <b>Pomona 5250</b>
- (SOIC-8) or <b>Pomona 5250</b> (SOIC-16) is recommended
- (<b>X200S and X200 Tablet users will need a soldering iron
- instead</b>, because of the type of package the flash chip is
- in on those machines).
- </li>
- <li>
- <b>External 3.3V DC power supply</b>. The one used by this
- author has the label HF100W-SF-3.3 on it, but any decent
- supply will be fine. Some people use the 3.3V from an ATX
- PSU for instance (the kind that you get on a typical
- Intel/AMD desktop computer. 6A supply should be fine,
- the one used by this author is 20A (it won't actually use
- that, it's just what the PSU is capable of).
- </li>
- <li>
- Dupont <b>jumper cables</b> (2.54mm / 0.1&quot; headers)
- You should get male-male, male-female and female-female
- cables in 10cm and 20cm sizes. Just get a load of them.
- </li>
- <li>
- <b>Mini USB A-B cable</b> (the BeagleBone probably already comes
- with one.)
- </li>
- <li>
- <b>FTDI serial board</b>, for unbricking the BeagleBone if
- necessary.
- </li>
- <li>
- <b>5V DC power supply</b> (from wall outlet to the BeagleBone).
- The BeagleBone can have power supplied via USB, but a
- dedicated power supply is recommended.

+ <h1>Initial BBB setup</h1>
- <h2>Setting up the 3.3V DC PSU</h2>
- <p>
- With my PSU, first I had wire up the mains power cable. Any clover or kettle lead will do. Cut the end off (not the one
- that goes in the wall, but the kettle/clover connector).
- Strip the protection away by a decent length, then strip the wires inside so that a decent amount of
- copper is shown. Then wire up earth/live/neutral. This will vary according to what country you live in
- and/or the colour codes that your cable uses inside. <b>Make sure to get this right, as a botched job
- could result in extreme damage to you and your surroundings. Here's what mine looks like after wiring up
- the power cable: <a href="images/x200/psu_power.jpg">images/x200/psu_power.jpg</a> - also, make sure
- that the plug (for the wall) has the correct fuse. In my case I had a 240V wall socket, and the device
- says that it accepts 1.5A at that voltage, so I used the smallest fuse available (3A). For 110-120V the device
- says it needs 2.8A.</b> Also, if yours looks like in the image linked above, make sure to wrap electrical tape (lots)
- around it for safety. (otherwise, don't touch the terminals while the PSU is plugged in).
- </p>
- <p>
- Now take a red and black 20cm female-female jumper lead, and cut one of the ends off. Strip away the bare copper by about 1 or
- 1.5cm so you get this: <a href="images/x200/stripped_jumper_lead.jpg">images/x200/stripped_jumper_lead.jpg</a>.
- </p>
- <p>
- Black goes on -V, red goes on +V. In my case, I removed those screws from my PSU like this:
- <a href="images/x200/psu_screws_removed.jpg">images/x200/psu_screws_removed.jpg</a>. Then,
- </p>
- <p>
- Then I twisted the exposed copper on the jumper leads (so that they don't fray), and wrapped each to one of the
- screws each, around it near the head. I then screwed them in:
- <a href="images/x200/psu_jumper_leads.jpg">images/x200/psu_jumper_leads.jpg</a>.
- </p>
- <p>
- If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied,
- continue reading...
- </p>
- <h2>Setting up the BBB</h2>
- <p>
- Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded.
- <a href="images/x200/strap.jpg">images/x200/strap.jpg</a> shows how I earthed myself. This is to prevent you
- from causing any ESD damage. The surface that you place components on should also be earthed/grounded.
- (for this, I used a shielded ESD bag with a wire, copper exposed, attached from the bag to the exposed metal
- part on a radiator, which was earthed - not professional, but it should work. see <a href="images/x200/mat.jpg">images/x200/mat.jpg</a>).
- Most people ignore this advice and don't ground/earth themselves, at their own risk. You should also store the BBB
- in a shielded anti-static bag when you are finished with it.
- (the principles above apply to any computer components, since they are extremely sensitive te ESD).
- </p>
- <p>
- These instructions may or may not work for you. They are simply the steps that this author took.
- </p>

- setting up SPIDEV on the BBB: <a href="http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0">http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0</a>
- - If you only setup SPI0, you don't have to disable the HDMI out. (you only need one).
- That guide is for seting up the device overlay for SPIDEV, last part is to make it persist across reboots.
- Needed to turn the BBB into an SPI flasher.
- </p>
- <p>
- Don't bother modifying uEnv.txt. it won't work;
- use the workaround here instead: <a href="http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes">http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes</a>.
- </p>
- <p>
- Follow the instructions at <a href="http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0">http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0</a>
- up to (and excluding) the point where it tells you to modify uEnv.txt
- </p>
- <p>
- You need to update the software on the BBB first. Before being able to use apt-get,
- I had to use the workaround defined <a href="https://groups.google.com/forum/?_escaped_fragment_=msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ#!msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ">here</a>:<br/>

+ sure not to connect the red/black 3.3v leads mentioned in the guide;
+ instead, connect the AC adapter (the one that normally charges your
+ battery) so that the board has power (but don't boot it up)</b>

</p>
+<pre>
+POMONA 5250:
+=== golden finger and wifi switch ====
+ 18 - - 1
+ 22 - - NC ---------- audio jacks are on this end
+ NC - - 21
+ 3.3V PSU RED - - 17 - this is pin 1 on the flash chip
+=== CPU fan ===
+<i>This is how you will connect. Numbers refer to pin numbers on the BBB, on the plugs near the DC jack.</i>

- On the 2nd machine, I did: <b>flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/x60t/libreboot_ukqwerty.rom</b>
- </p>
-
- <pre>
- flashrom v0.9.5.2-r1517 on Linux 3.2.0-61-generic (i686), built with libpci 3.1.8, GCC 4.6.3, little endian
- flashrom is free software, get the source code at http://www.flashrom.org
-
- Calibrating delay loop... delay loop is unreliable, trying to continue OK.
- Found Macronix flash chip "MX25L1605" (2048 kB, SPI) on buspirate_spi.
- Reading old flash chip contents... done.
- Erasing and writing flash chip... Erase/write done.
- Verifying flash... VERIFIED.
- </pre>
-
<p>
- At the end it says "VERIFIED", which means that the procedure worked. If you see this, it means that you can put your X60T back together. So let's do that now.
+ It should be <b>Verifying flash... VERIFIED</b> at the end. If flashrom complains about multiple flash chip
+ definitions detected, then choose one of them following the instructions in the output.
