Test-Results for "Pm25LV512(A)"
by The Raven 04 Feb '15

04 Feb '15

Hello :-) Here are the results for this chip. Tested with Arduino (serprog). Probing: OK Reading: OK Erasing: OK Writing: OK The writing (sign) on the Chip is: Pm25LV512 AE1034 M23360LG Should i test something else? BTW: This chip was found on a "newer" nvidia graphic card (GF108 / Gforce GT430 / 1GB Ram).

FOSDEM 2015

Hi everyone! 31 Jan 2015 and 1 Feb 2015: https://fosdem.org/2015/news/2014-09-19-call-for-participation-part-two/ I would love to be there again and some of you already said they'd try to be there, but I forgot who. Who can be there with me at the booth and when can you be there? A preliminary stand application has already been sent by me to somewhat hit the deadline, but I'd like to fill it in a bit more. Side note: If someone has an interesting topic for a lightning talk, please submit one! Regards, Carl-Daniel

[PATCH]Build everything on request
by Patrick Georgi 19 Jan '15

19 Jan '15

Hi, attached patch adds a BUILD_EVERYTHING flag to Makefile that sets all CONFIG_* flags to "yes" if they were "no". This provides a comfortable way to ensure maximum code exposure to tools like coverity[0] or clang's scan-build. BUILD_EVERYTHING will likely fail on non-Linux/x86 systems, but it seems that's a hard dependency to compile everything at this time, so well... Signed-off-by: Patrick Georgi <patrick(a)georgi-clan.de> Regards, Patrick [0] https://scan.coverity.com/projects/1020

Thanks a lot! Hello Alex, I'd like to add support for this chip to vanilla flashrom as well but could not find a public datasheet to add a few additional bits. Will this chip and a respective datasheet be available publicly? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

flashrom v0.9.7-r1711 on Linux 3.17.7-gentoo (x86_64) flashrom is free software, get the source code at http://www.flashrom.org flashrom was built with libpci 3.2.0, GCC 4.8.3, little endian Command line (3 args): flashrom --programmer internal -V Calibrating delay loop... OS timer resolution is 1 usecs, 1594M loops per second, 10 myus = 10 us, 100 myus = 100 us, 1000 myus = 1001 us, 10000 myus = 10005 us, 4 myus = 4 us, OK.

Please send the output of "flashrom -V" to flashrom(a)flashrom.org with W836xx: your board name: flashrom -V as the subject to help us finish support for your Super I/O. Thanks. Found ITE EC, ID 0x8587, Rev 0x06 on port 0x2e. ======================================================================== WARNING! You seem to be running flashrom on an unsupported laptop. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and http://www.flashrom.org/Laptops for details. If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== Aborting. Error: Programmer initialization failed.

Re: [flashrom] Intel 28F001BN/BX-T erase/write operation verified on 3C905B-TXNM

The successful log does not correspond 100% with the first one: the failure happens at the very beginning of the flash address space while the successful write does skip the first blocks and does only erase and write the last one. This can easily happen depending on the existing data and the image provided to flashrom. Just to make sure... can you please elaborate what happened between the two attempts that could explain what I wrote above? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
