[PATCH 0/6] ichspi 9.0
by Stefan Tauner 06 Oct '11

06 Oct '11

hwseq is split and hopefully i have addressed all triaged problems. there are some open questions in my last mail (201109181517.p8IFHdlp027261(a)mail2.student.tuwien.ac.at) though. 4/6 is new and cuts down unnecessary output in the case of non-descriptor mode boards. 5/6 is also new, but not finished, see specific commit log for details please. there were long periods between edits and the major part of the changes were made with quite some headache, be aware please. :) Stefan Tauner (6): ichspi: add (partially) dead support code for Intel Hardware Sequencing ichspi: add support for Intel Hardware Sequencing compile fix for hwseq due to reverting the "unsignify" patch ichspi: print flash descriptor dependent information only when it is valid ichspi: warn if regions defined by FREGs do not cover the whole flash space Add ich_descriptor_tool to decode all flash descriptors stored in a flash dump file chipdrivers.h | 6 + flashchips.c | 23 +- flashchips.h | 2 + ich_descriptors.c | 560 +++++++++++++++++++++ ich_descriptors.h | 328 +++++++++++++ ichspi.c | 572 ++++++++++++++++++++-- programmer.h | 1 + util/ich_descriptors_tool/Makefile | 42 ++ util/ich_descriptors_tool/TODO | 6 + util/ich_descriptors_tool/ich_descriptors_tool.c | 225 +++++++++ 10 files changed, 1723 insertions(+), 42 deletions(-) create mode 100644 util/ich_descriptors_tool/Makefile create mode 100644 util/ich_descriptors_tool/TODO create mode 100644 util/ich_descriptors_tool/ich_descriptors_tool.c

Fujitsu Esprimo P9900 (locked ME region)
by Stefan Tauner 04 Oct '11

04 Oct '11

hi there regarding your question on IRC and this log: http://paste.flashrom.org/view.php?id=840 your board (vendor) has locked a region of the flash, which we can not unlock. intel does not provide the necessary information to us, but only hardware vendors and bios programmers. can you please elaborate what you want to accomplish exactly? if the Management Engine region is not important to you, i have a few patches that would allow you to read the other regions. you can read a bit about the problem here: http://blogs.coreboot.org/blog/2011/08/17/gsoc-2011-flashrom-part-5-–-dear-… and on our email archive: http://www.flashrom.org/pipermail/flashrom/ please note that this mail is also addressed to our mailing list, and your reply will (probably) also be sent there. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Intel SCH Poulsbo
by MONDON Daniel 04 Oct '11

04 Oct '11

Hi! Flashrom V0.9.4-r1395 results: Found chipset « Intel SCH Poulsbo” Found SST flash chip “SST49LF008A” (1024kB, FWM) @ 0xfff00000 I am under TCL (TinyCore Linux). Flashing Bios is OK, but erasing flash need many loops to erase all flash (from 0x1000 to 0xFF000 = 256 loops). But sometimes, it is ok in one time. What can I do to increase erasing speed (times) … or is there any known bug … perhaps increasing timeout … or ? Thanks Daniel.

this was fixed by retry (or so :), see below for the log of the IRC conversation. * cupantae (~mark@*) has joined #flashrom <cupantae> I tried to update my bios but now even the writing the backup gives an error. What can I do? <cupantae> I have emailed flashrom(a)flashrom.org with the report <idwer> first thing to not do is reboot, second thing is to upload the whole output to http://paste.flashrom.org <cupantae> ok. done <cupantae> i'm not sure if this is helpful, but at the "VERIFY FAILED", it gave a different reason each time <cupantae> first it was at 0x000acd00!

It's also 50.0 % identical to file asusbios.bin' instead of something along the lines of 'verification failed, file is corrupt'. Above example would also require a way to reference a 2nd file to verify against. Let's say that 2nd file is an internet-downloaded original motherboard vendor's BIOS instead of a flashrom dumped file. After all, people might want to check if flashrom works correctly before writing anything. What better way than dump current bios, compare dumped file to bios but also compare to vendor bios file. All 3 should be (near-)identical.
