Same here for Vanta (Atmel AT27LV512A). Or it is intentionally to not support those 27's chips which are One-Time-Programmable?

Thanks for the info. I've found that it MIGHT be supported by flashrom. It does look for memory (see log). I checked the chip and it's Holtek ht27c512 (it's 64k - good sign?) which seems to be, simply, unsupported by flashrom. Can You add its support?

Unsupported 3com device (3c905 100BaseTX [Boomerang])
by san 22 Oct '13

Hi! I own: 02:00.0 Ethernet controller [0200]: 3Com Corporation 3c905 100BaseTX [Boomerang] [10b7:9050] It's unsupported: ---[code]--- Error: No supported PCI device found. Error: Programmer initialization failed. ---[/code]--- I would love to help You to get it to work with flashrom. Do You need it? Regards! -- [ e-San.info | San(a)plusnet.pl ]

Let's say it is very misleading: it means that everything the driver is able to do works with the PCI card in question. Normally we do not commit such incomplete drivers, but I guess Uwe has slipped it in (NB: way before I was around :) and there is no way to express "read-only" in the hardware tables (yet). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

On page http://flashrom.org/Supported_hardware we can find information that it is OK. So it is not correct? 2013/10/22 san <san(a)plusnet.pl> > I ani going to buy riva to program some bioses with it.

Parallel ofcourse. I could be wrong, but I think the gfxnvidia driver is not able to write/erase at all. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

[PATCH] Make delay values unsigned.
by Stefan Tauner 21 Oct '13

21 Oct '13

There is no reason for negative delays in our use cases: - We don't need it (to work around any quirks). - sleep() (POSIX) uses an unsigned argument. - usleep() (POSIX) uses an unsigned argument. - Sleep() (Windows) uses an unsigned argument.

(Un)documented devices
by san 21 Oct '13

21 Oct '13

Hi! Just wanted to report some undocumented stuff. I've been working on 3com nic device: 02:00.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 30) which seems to be reported as working on wiki - and it does ;) First thing: Winbond W29EE011 (128k, parallel) works well, but not auto (needs to be forced by '-c') - yes, i know why. I'm not sure if it was while programming this one or Pm..., but it dropped message about 'retrying to flash', and it worked well after all. Second: PMC "Pm29F002T" (256 kB, Parallel) works fine until write (since it is too big for 3com [256 vs 128 kB]). I'll try to read content of this one after erase command. Intersting thing: i write a bit modified oryginal bios, i changed one letter about the end of 256kb: Oryginal: BOOT Modifed: LOOT Write&Read: @OOT Another suggestion of mine: meybe add to PCI-devices list maximal chip size support? All files (including rom's (un)modified and reflased&read) are avialable here: http://www.e-san.info/Go!/deeper!/Flashrom/13.10.21/ . Hope it is useful report. Best regards! -- [ e-San.info | San(a)plusnet.pl ]
