- At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):<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/>
- 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/>
+ Now wire up the BBB and the Pomona with your PSU.<br/>
+ Refer to <a href="bbb_setup.html">bbb_setup.html</a> for how to setup

+ <b>Note, the guide mentions a 3.3v DC PSU but you don't need this on the X60 Tablet:

+ 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>

- 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.
