      Hi, I got your emails just fine, I just didn't have time to sit down and write a
proper reply but I'm very enthusiasic about working with you !

Cheers,

  Good day! I just tried reading from KB9012 and
encountered exactly the same
 problem as Joerg Albert has ( https://www.flashrom.org/pipermail/flashrom/2016
 -May/014653.html ) - chip is detected only every second time. This is not
 caused by cabling. While it is recommended for SPI that the wires should be
 shorter than 20cm, my wires are 11 cm: 8 cm of which is 12 strands high
 quality copper and only 3 cm are ordinary aluminium inside the 30 pin 0.5mm
 pitch keyboard-like connector 
This is interesting! I still haven't been able to reproduce the issue (but
haven't tried so hard either). Could you indicate whether you are:
* grounding pin 42 to go into test mode
* powering the mainboard

Thanks!

...
  NOTE: it was much easier and safer to solder 1P wires
to this connector rather
 than to motherboard, and you could remove/insert it at any time - what a great
 convenience! The only 1P wire I had to solder to motherboard is to
 motherboard's ground, - to make it possible to unite three grounds
 (motherboard s, KB9012 s and programmer s) - and that was really easy because
 at least one of these orange circle grounds has a great distance between it
 and motherboard's elements so it is difficult to screw up there :) Going to
 share photos and write some manuals about connectivity, hopefully helpful to
 the people like me who want to participate in Origami EC project - creation of
 open source firmware for KB9012 which in case of success will be a HUGE step
 towards Lenovo G505S liberation (AMD laptop with coreboot support) .
 Discovered Paul's presentation talk by pure accident -
 https://www.youtube.com/watch?v=B708jdCiW7o

 So I tried using two SPI programmers: 1) CH341A . 2) Bus Pirate v4 . The only
 observed difference is a speed: for CH341A read takes 13-14 minutes, while for
 BPv4 - despite the latest 7.0 firmware with level 3 optimizations ( http://dan
 gerousprototypes.com/docs/Bus_Pirate#Download ) and SPI speed is 8 MHz - it
 takes 40 minutes to read! Checksums of the files are the same and the files
 have almost the same contains as KB9012 image for LA-A091P G505S that I found
 online (same except the area 0x1d000 - 0x1e0f0, their image is filled with
 0xff there, mine has many 0x00 with a few 0xff and also data - probably
 encoded serial number and similar stuff) , so I am pretty sure these
 programmers both are reading without errors in my setup, just at the different
 speeds for some weird reason

 Patches applied before testing:
 1) https://patchwork.coreboot.org/patch/4412/
 2) https://patchwork.coreboot.org/patch/4413/
 3) https://patchwork.coreboot.org/patch/4414/

 This problem with 1/2 detection rate is not a blocker, more like a small
 inconvenience, so I strongly believe that these patches should be merged as
 soon as possible! Paul Kocialkowski has committed them almost a year ago, such
 a major feature and still not merged??

 Below you could see some -VVV detection logs.

 After reading this really inspiring article ( http://code.paulk.fr/article25/a
 n-incentive-for-liberating-computers-my-own-use-case ) I guess that Paul's
 motherboard is LA-A092P, very similar to LA-A091P but no extra GPU. Could that
 be a reason he is not getting a detection problem? Just a wild guess...

 Yours sincerely,
 Mikeb
