MSI K9N6PGM2-V: flashrom -V
by appzer0 20 Jul '14

20 Jul '14

Hi Flashrom folks, Please find below (and attached) the flashrom probe output, plus the flashrom -V output, all with the "--programmer internal" option. Please notice that this motherboard is not the one which is referenced on your website, named "MSI K9N6PGM2-V2" (Notice the extra "2" at the end). Note that the verbose probe shows a SST25VF080B chip detected, which is listed as 100% working on your website. So I guess this is good but a confirmation would be much appreciated. :) Thanks for all the great work! appzer0 - http://0linux.org ---

Hi, not it is of course not normal :) and more or less it was for maintenance: the wiki was upgraded. There was also a DNS issue which may have been the cause of what you saw (and why your mail was deferred so long too). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

[PATCH] Rename programmer registration functions
by Carl-Daniel Hailfinger 19 Jul '14

19 Jul '14

register_programmer suggests that we register a programmer. However, that function registers a master for a given bus type, and a programmer may support multiple masters (e.g. SPI, FWH). Rename a few other functions to be more consistent.

Author: hailfinger Date: Sun Jul 20 00:03:29 2014 New Revision: 1831 URL: http://flashrom.org/trac/flashrom/changeset/1831 Log: Rename programmer registration functions register_programmer suggests that we register a programmer. However, that function registers a master for a given bus type, and a programmer may support multiple masters (e.g. SPI, FWH). Rename a few other functions to be more consistent.

[PATCH] Add new programmer for SPI EEPROMs attached to Intel 82580 NICs.
by Stefan Tauner 17 Jul '14

17 Jul '14

This patch lets you read and write the EEPROM on 82580-based gigabit NIC cards. So far it has been tested on copper NICs only, but other variants employing this controller should work too. It is a nice substitution for the official eeupdate tool. Speed is quite decent: less than 5 seconds for writes of 32 kB chips. Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda(a)gmail.com> Signed-off-by: Stefan Tauner <stefan.tauner(a)alumni.tuwien.ac.at> Acked-by: Stefan Tauner <stefan.tauner(a)alumni.tuwien.ac.at> --- Hello Ricardo, the patch is not merged yet but I think the final version is attached below (applicable to r1830). We have integrated proper support for EEPROM semantics in r1822 which is used in this patch. This allows flashrom to write without prior erases which were implicitly scheduled without said patch unnecessarily on EEPROMs. Maybe this even speeds up things a bit. I'll commit the patch as soon as it got tested.
