Stefan, Thanks for the very detailed answer. Best Regards.

The board was already reported earlier (to be not working due to the locked region), see http://www.flashrom.org/pipermail/flashrom/2012-July/009522.html The chipset itself would most probably work, but we only mark it that way after successful writes (which is currently not possible on that board). And finally, the flash chip (Numonyx N25Q128) on that board is not fully supported yet, but would probably work well enough (with some generic code, namely SFDP). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

[PATCH] Support chips MBM29F040 and W29EE512
by Andreas Seltenreich 08 Aug '12

08 Aug '12

Hi, I had to modify my copy a bit to use the PLCC chips I had salvaged somewhere as boot ROMs in Intel NICs. Patch attached. I'm not sure if the 512kB one qualifies as tested because the programmer only supports 128kB, and I had to --force it. regards, andreas

[PATCH] Automatically release I/O permissions on shutdown
by Carl-Daniel Hailfinger 08 Aug '12

08 Aug '12

get_io_perms() is renamed to rget_io_perms() and automatically registers a function to release I/O permissions on shutdown. Actually release I/O permissions on Solaris and iopl()-supporting operating systems like Linux. This patch fixes quite a few programmers which forgot to release I/O permissions on shutdown, and it simplifies the shutdown and error handling code for all others. Note: The next steps will be to do the same with PCI init and /dev/mem accesses. That should make probably 3/4 of all explicit shutdown functions empty and obsolete.

You certainly want to save the original rom content, maybe store it on another machine, or get a spare chip to program coreboot.rom to. If you prefer to use an external programmer for SPI chips I can recommend the buspirate: http://flashrom.org/Bus_Pirate and compatible soic8 clips, if the flash is soldered to the board, http://www.hmcelectronics.com/product/Pomona/5250 > > Thanks > -- > Hoang Tung (Mr) > > > > > _______________________________________________ > flashrom mailing list > flashrom(a)flashrom.org > http://www.flashrom.org/mailman/listinfo/flashrom
