Hi,

my Name is Johannes Merkert and I am an author for the german computer
magazine c't (ct.de). I tried to install Libreboot on a ThinkPad T400
following the guide on libreboot.org
(https://libreboot.org/docs/install/t400_external.html).

When I tried to test flashrom with the BIOS chip I got the following
error:

address@hidden:~# ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=5
12
flashrom v0.9.8-unknown on Linux 3.8.13-bone79 (armv7l)
flashrom is free software, get the source code at http://www.flashrom.or
g

Calibrating delay loop... OK.
Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on
linux_spi.
===
This flash part has status NOT WORKING for operations: PROBE READ
ERASE WRITE
The test status of this chip may have been updated in the latest
development
version of flashrom. If you are running the latest development version,
please email a report to address@hidden if any of the above
operations
work correctly for you with this flash chip. Please include the
flashrom log
file for all operations you tested (see the man page for details), and
mention
which mainboard or programmer you tested in the subject line.
Thanks for your help!
No operations were specified.

Does this mean my T400 uses another flash chip and I can not upgrade
it to libreboot?

Faithfully,
  Johannes Merkert
