Flashing the R400 with a BeagleBone Black

Initial flashing instructions for X200.
+
+ This guide is for those who want libreboot on their ThinkPad R400 + while they still have the original Lenovo BIOS present. This guide + can also be followed (adapted) if you brick your R400, to know how + to recover. +
+
+ Before following this section, please make sure to setup your libreboot ROM properly first. + Although ROM images are provided pre-built in libreboot, there are some modifications that + you need to make to the one you chose before flashing. (instructions referenced later in + this guide) +

Flash chips
+ +
+ There are two possible flash chip sizes for the R400: 4MiB + (32Mbit) or 8MiB (64Mbit). This can be identified by the type + of flash chip below the palmrest: 4MiB is SOIC-8 (8 pins), 8MiB + is SOIC-16 (16 pins). The X200S uses a WSON package and has the same + pinout as SOIC-8 (covered briefly later on in this guide) but + the chip is on the underside of the board (disassembly required). +

+ Refer to bbb_setup.html for how to + setup the BBB for flashing. +
+ +
+ The following shows how to connect clip to the BBB (on the P9 header), for SOIC-16 (clip: Pomona 5252): +

+ images/r400/r400_pomona.jpg + shows everything connected. In this picture, the R400 is being flashed + with the BBB. +
+
+ No disassembly instructions yet, unfortunately.

+
+ I did (SSH'd into the BBB):
+ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512
+ In my case, the output was: +
+
+flashrom v0.9.7-r1854 on Linux 3.8.13-bone47 (armv7l) +flashrom is free software, get the source code at http://www.flashrom.org +Calibrating delay loop...

+
+ This is just to test that it's working. In my case, I had to define which chip to use, like so (in your case + it may be different, depending on what flash chip you have):
+ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c "MX25L6405(D)" +
+
+ At this point, you need to create a copy of the original lenovo firmware that is currently flashed. + This is so that you can extract the gbe (gigabit ethernet) and flash descriptor regions for use in libreboot. These + are not blobs, they only contain non-functional data (configuration details, fully readable) which is fully documented in public datasheets. + The descriptor will need to be modified + to disable the ME (also disable AMT) so that you can flash a ROM that excludes it. +
+
+ How to backup factory.rom (change the -c option as neeed, for your flash chip):
+ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c "MX25L6405(D)" -r factory.rom
+ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c "MX25L6405(D)" -r factory1.rom
+ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c "MX25L6405(D)" -r factory2.rom
+ Now compare the 3 images:
+ # sha512sum factory*.rom
+ If the hashes match, then just copy one of them (the factory.rom) to a safe place (on a drive connected to another machine, not + the BBB). You will need it later for part of the deblobbing. +
+
+ Information about the descriptor, gbe regions and how the ME was removed can be found in the notes linked at + ../hcl/gm45_remove_me.html. Libreboot ROM images now include + the 12KiB descriptor+gbe by default, generated using ich9gen; + however, do note that the MAC address in the Gbe region is generic. Follow the instructions at + ../hcl/gm45_remove_me.html#ich9gen and do what it says to change the MAC address + inside your R400 ROM image, before flashing it. +
+
+ Assuming that your libreboot ROM image is properly setup (modified descriptor plus gbe region included in the ROM), + then you can flash (assuming that the filename is libreboot.rom) for example I had to do:
+ # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -c "MX25L6405(D)" -w libreboot.rom +
+
+ You might see errors, but if it says Verifying flash... VERIFIED at the end, then it's flashed and should boot. + Test it! (boot your R400) +
