Documentation: *major* cleanup.
Cleanup was long overdue. Old structure was messy and inefficient.

For me, this was (see: "SparkFun cable pin reference"):<br/> - <a href="http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts" target="_blank">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" target="_blank">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" target="_blank">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/> - <img src="x60_unbrick/0017.jpg" alt="" /> - </p> - - <p> - My programmer, usb cable and clip:<br/> - <img src="x60_unbrick/0018.jpg" alt="" /><br/> - My programmer (bus pirate):<br/> - <img src="x60_unbrick/0019.jpg" alt="" /><br/> - My clip (pomona 5250):<br/> - <img src="x60_unbrick/0020.jpg" alt="" /><br/> - My USB mini a to b cable:<br/> - <img src="x60_unbrick/0021.jpg" alt="" /><br/> - Connecting the pomona:<br/> - <img src="x60_unbrick/0022.jpg" alt="" /><br/> - Connecting the USB cable from programmer to 2nd(working/non-bricked) computer, my T60:<br/> - <img src="x60_unbrick/0024.jpg" alt="" /><br/> - Programmer is now active:<br/> - <img src="x60_unbrick/0023.jpg" alt="" /><br/> - Now I install flashrom on the T60 (running Trisquel GNU/Linux) and do this:<br/> - <b>flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/x60/libreboot_usqwerty.rom</b><br/> - Note: there are also other ROM images for X60<br/> - Note: this is using buspirate as the programmer, so it is flashing the X60, not the T60!<br/> - Here's my terminal window on the T60:<br/> - <img src="x60_unbrick/0025.jpg" alt="" /><br/> - So, you should see the following:<br/> - -- - <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> - --<br/> - At the end it says "VERIFIED", which means that the procedure worked. If you see this, it means - that you can put your X60 back together. So let's do that now. - </p> - <p> - Remove the programmer and put it away somewhere. Put back the tape and press firmly over it:<br/> - <img src="x60_unbrick/0026.jpg" alt="" /> - </p> - <p> - Your empty chassis:<br/> - <img src="x60_unbrick/0027.jpg" alt="" /> - </p> - <p> - Put the motherboard back in:<br/> - <img src="x60_unbrick/0028.jpg" alt="" /> - </p> - <p> - Reconnect SATA:<br/> - <img src="x60_unbrick/0029.jpg" alt="" /> - </p> - <p> - Put the plate back and re-insert those screws:<br/> - <img src="x60_unbrick/0030.jpg" alt="" /> - </p> - <p> - Re-route that antenna cable around the fan and apply the tape:<br/> - <img src="x60_unbrick/0031.jpg" alt="" /> - </p> - <p> - Route the cable here and then (not shown, due to error on my part) reconnect the monitor cable to the motherboard - and re-insert the screws:<br/> - <img src="x60_unbrick/0032.jpg" alt="" /> - </p> - <p> - Re-insert that screw:<br/> - <img src="x60_unbrick/0033.jpg" alt="" /> - </p> - <p> - Route the black antenna cable like so:<br/> - <img src="x60_unbrick/0034.jpg" alt="" /> - </p> - <p> - Tuck it in neatly like so:<br/> - <img src="x60_unbrick/0035.jpg" alt="" /> - </p> - <p> - Route the modem cable like so:<br/> - <img src="x60_unbrick/0036.jpg" alt="" /> - </p> - <p> - Connect modem cable to board and tuck it in neatly like so:<br/> - <img src="x60_unbrick/0037.jpg" alt="" /> - </p> - <p> - Route the power connection and connect it to the board like so:<br/> - <img src="x60_unbrick/0038.jpg" alt="" /> - </p> - <p> - Route the antenna and modem cables neatly like so:<br/> - <img src="x60_unbrick/0039.jpg" alt="" /> - </p> - <p> - Connect the wifi antenna cables. At the start of the tutorial, this machine had an Intel wifi chip. Here you see I've replaced it with an - Atheros AR5B95 (supports 802.11n and can be used without blobs):<br/> - <img src="x60_unbrick/0040.jpg" alt="" /> - </p> - <p> - Connect the modem cable:<br/> - <img src="x60_unbrick/0041.jpg" alt="" /> - </p> - <p> - Connect the speaker:<br/> - <img src="x60_unbrick/0042.jpg" alt="" /> - </p> - <p> - You should now have this:<br/> - <img src="x60_unbrick/0043.jpg" alt="" /> - </p> - <p> - Re-connect the upper chassis:<br/> - <img src="x60_unbrick/0044.jpg" alt="" /> - </p> - <p> - Re-connect the keyboard:<br/> - <img src="x60_unbrick/0045.jpg" alt="" /> - </p> - <p> - Re-insert the screws that you removed earlier:<br/> - <img src="x60_unbrick/0046.jpg" alt="" /> - </p> - <p> - Power on!<br/> - <img src="x60_unbrick/0047.jpg" alt="" /> - </p> - <p> - Trisquel live USB menu (using GRUB's ISOLINUX parser):<br/> - <img src="x60_unbrick/0048.jpg" alt="" /> - </p> - <p> - Trisquel live desktop:<br/> - <img src="x60_unbrick/0049.jpg" alt="" /> - </p> - -<hr/> - - <p> - Copyright © 2014 Francis Rowe <info@gluglug.org.uk><br/> - This document is released under the Creative Commons Attribution-ShareAlike 4.0 International Public License and all future versions. - A copy of the license can be found at <a href="../license.txt">../license.txt</a>. - </p> - - <p> - This document is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
