Re: [flashrom] Marvell 9120 SATA Controller/Macronix MX25L4005 EEPROM on ASUS P7p55D-E LX
please always reply to the mailing list. some stuff about in-system programming that might be partially relevant to you: http://flashrom.org/ISP
a special flashrom version for the chip is not needed at all, you seem to be way too focused on that. normally flashrom will detect that chip by itself. if not then the communication does not work reliable. there is also an option to look for a specific chip only instead of all compatible chips (-c MX25L4005).

Stefan Tauner:
Thanks for your reply.
I bricked the onboard Marvell 9120 SATA controller by flashing the sata controller itself using the marvell flash tool with firmware for another controller model (stupidly). When I try to force a flash I now get a "Adapter Not Found" message. I'm sure the sata controller firmware is on a Macronix MX25L4005 EEPROM located adjacent to the Marvell onboard sata controller according to information for the Marvell 9120 SATA controller and from reading about the experience of others with similar problems and hardware. Flashing the mainboard bios has no effect. Besides, the Macronix MX25L4005 has 512k memory and the mainboard bios files are 2048k.
I'm considering using a buspirate and flashrom to flash the MX25L4005. I'll probably try to flash the MX25L4005 while it is still soldered onto the mainboard but not powered by the mainboard, and supply power to the MX25L4005 separately from the board, although I have read where others have had to either lift their MX25L4005 vcc leg from it's mainboard or remove the MX25L4005 entirely for a successful flash.
I believe I have a good full copy of the firmware that I overwrote, I just need to purchase a buspirate and set of probes or a clamp and use the correctly compiled flashrom. At this point having a version of flashrom complied to specifically flash a MX25L4005 would be a great help along with any other advice you might have for me.

oh. onboard sata chip. obviously i was the one confused, sorry.
how did you brick it? if the firmware is stored in the normal flash as flashrom sees it (which is likely), flashing the normal mainboard updates should fix it. what about the flashing tools from asus... did you try recovering with them?
Flashrom Support:
OK I decided I want to flash a MX25L4005A soldered in a ASUS P7P55D-E LX motherboard.
Could you recommend an EEPROM programmer and probes/clamp to use with flashrom that I can purchase in the USA for this purpose?
Thanks.
