From: Francis Rowe Or go back to main index
+ Shopping list (pictures of this hardware is shown later):
+
+ 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. 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: images/x200/psu_power.jpg - 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. 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).
+
+ 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: images/x200/stripped_jumper_lead.jpg.
+
+ Black goes on -V, red goes on +V. In my case, I removed those screws from my PSU like this:
+ images/x200/psu_screws_removed.jpg. Then,
+
+ 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:
+ images/x200/psu_jumper_leads.jpg.
+
+ If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied,
+ continue reading...
+
+ 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.
+
+ Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded.
+ images/x200/strap.jpg 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 images/x200/mat.jpg).
+ 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).
+
+ These instructions may or may not work for you. They are simply the steps that this author took.
+
+ setting up SPIDEV on the BBB: http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0
+ - 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.
+
+ Don't bother modifying uEnv.txt. it won't work;
+ use the workaround here instead: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes.
+
+ Follow the instructions at http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0
+ up to (and excluding) the point where it tells you to modify uEnv.txt
+
+ You need to update the software on the BBB first. Before being able to use apt-get,
+ I had to use the workaround defined here:Setup the BeagleBone Black as an SPI flashrom programmer

- At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):
- http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts.
- Correlating with the following information, I was able to wire up my pirate correctly:
- http://flashrom.org/Bus_Pirate#Connections
- And by following that advice:
- http://www.coreboot.org/Board:lenovo/x60/Installation#Howto.
- (it says X60 but instructions are virtually the same for the T60, with except to physical differences in how to disassemble the machine)
- Note: that last page says to wire up only those 5 pins (see below) like that: 1, 2, 4, 5, 6.
- 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).
- Note: I ignored that advice, and wired up all 8 pins. And it worked.

+ Connect the pomona from the BBB to the flash chip. No pics unfortunately. (use the text diagram above).
- Now flash the bricked machine using the 2nd computer. in my case I did:
- flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/t60/libreboot_usqwerty.rom
- Note: there are also other ROM images for T60
- Note: this is using buspirate as the programmer, so it is flashing the T60, not the 2nd computer!
- Here's my terminal window on the 2nd computer (also the programmer is active):

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

- Here's my terminal window on the T60:

Remove the programmer and put it away somewhere. Put back the tape and press firmly over it:
You still have Lenovo BIOS, or you had libreboot running and you flashed another ROM; and you had bucts 1 set and

Remove that screw and then remove the board:
- At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):
- http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts.
- Correlating with the following information, I was able to wire up my pirate correctly:
- http://flashrom.org/Bus_Pirate#Connections
- And by following that advice:
- http://www.coreboot.org/Board:lenovo/x60/Installation#Howto.
- Note: that last page says to wire up only those 5 pins (see below) like that: 1, 2, 4, 5, 6.
- 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).
- Note: I ignored that advice, and wired up all 8 pins. And it worked.

- Here is the pinout (correlate it with your programmer's documentation):
+ Now wire up the BBB and the Pomona with your PSU.
+ Refer to bbb_setup.html for how to setup
+ the BBB for flashing.
+ Note, the guide mentions a 3.3v DC PSU but you don't need this on the X60 Tablet:
+ if you don't have or don't want to use an external PSU, then make
+ 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)
