Author: hailfinger Date: 2009-09-28 15:15:16 +0200 (Mon, 28 Sep 2009) New Revision: 736 Added: trunk/bitbang_spi.c Modified: trunk/Makefile trunk/flash.h trunk/flashrom.c Log: This is the bitbanging SPI driver infrastructure. If you want support for a particular piece of hardware, just fill in a few functions in spi_bitbang_master_table. That's it. On top of this, the RayeR SPI flasher should be supportable in ~20 LOC. Tested, trace looks OK.

Success: flashing BIOS on MSI K9AG Neo2-Digital (MS-7368)
by christian.ch.heinz＠gmail.com 28 Sep '09

28 Sep '09

Hello flashrom people, here is a quick success report on using flashrom with the MS-7368 (revision 1.0; I don't believe there are any later revisions, but I'm not sure). The exact flashrom version used was v0.9.1, SVN revision r721. In particular, I first upgraded the BIOS from version 1.9 to 1.10 (named 1.A on the MSI website), then downgraded to 1.7 and re-upgraded to 1.8 and finally to 1.10 again, with a reboot following each flashing. I also played around with a few of the flashrom options and everything worked flawlessly OOTB. Some details: # ./flashrom -r ... flashrom v0.9.1-runknown No coreboot table found. Found chipset "AMD SB600", enabling flash write... OK. This chipset supports the following protocols: LPC,FWH,SPI. Calibrating delay loop... OK. Found chip "Winbond W25x80" (1024 KB, SPI) at physical address 0xfff00000. Reading flash... done. # ./superiotool superiotool r4623 Found Fintek F71882FG/F71883FG (vid=0x3419, id=0x4105) at 0x4e Platform: Linux 2.6.30-ARCH x86_64 AMD Athlon(tm) Dual Core Processor 4850e Probably nothing more to add, except that flashrom absolutely rocks :) Thanks and kudos, ch

3C905CX-TX-M not supported (But flashrom thinks it is).
by Marko Kraljevic 25 Sep '09

25 Sep '09

Hi, the other day I got a 3C905CX-TX-M NIC. I don't have the computer I tested it on up and running right now, but it is non-functional. Flashrom can not detect the AT49BV512 on it. A forced read delivers all 0xFF's, which I assume it is pulling out of the ether. I guess it *could* be blank; It seems unlikely to not autodetect and function on a forced read though. Anyways, this wouldn't be an issue, but the PCI device ID is the same as the 3C905C-TX [dev_id 0x9200] (*iirc - it might be one of the other supported 3C905 NICs*), so flashrom reports it as a supported NIC. I guess there should be a note somewhere, specifying that flashrom doesn't support 3com NICs with the newer, smaller, BGA package ASIC. Here's a photo of the card. On mine the flash is soldered on, but I believe I've seen socketed versions in the past. If they're all soldered on, I guess it doesn't matter much - apart from saving someone the time of soldering on a socket. http://electrontube.org/open/3com_mod/3C905CX-TX-M.jpg I'll try and get that computer back up this weekend and post the output.

actual bios settings
by Bart Swinnen 24 Sep '09

24 Sep '09

Hi Does flashrom normally also reads actual BIOS setting of a board? I'm trying flashrom on IEI Wafer-LX-800 It finds PMC Pm49FL004 device and I can read it. It gives me a 512k bin file. If I write this file to another board of its kind, I still have the actual settings of that board and not the one stored in the board where I had the bin from. Am I missing something? Kind regards Bart Swinnen

[PATCH] Switch SST49LF004A/B to blockwise erase
by Carl-Daniel Hailfinger 24 Sep '09

24 Sep '09

Switch SST49LF004A/B to block erase, remove the hack which simulated (unsupported) chip erase. Annotate SST49LF004B quirks for TBL#. Add TEST_OK_PRW which is useful when a PREW chip gets a new erase routine. Change a few erase function prototypes to use unsigned int instead of int.
