Re: [flashrom] [PATCH] Add native AAI transfer support to the dediprog driver
by Nico Huber 19 Jun '12

19 Jun '12

Second try for this patch. This enables native AAI transfer support in the dediprog driver. The function to write chunks of data, dediprog_spi_bulk_write(), is reused. To tell the programmer how to handle the data on the spi bus, a flag in the fourth byte sent with the usb command is used. The second word was mistaken for the size of the chunks sent over usb earlier. The third byte (first of the second word) is now set to zero. This also adds some checks for the size of data chunks sent over usb.

Re: [flashrom] Marvell 9120 SATA Controller/Macronix MX25L4005 EEPROM on ASUS P7p55D-E LX
by Stefan Tauner 18 Jun '12

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). Begin forwarded message: Date: Fri, 25 May 2012 18:19:27 -0400 From: "Richard R. Blum" <rrblum(a)gmail.com> To: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at> Subject: Re: [flashrom] Marvell 9120 SATA Controller/Macronix MX25L4005 EEPROM on ASUS P7p55D-E LX 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. R.

[PATCH] Enable spi clock setting in dediprog driver

[PATCH] Let the programmer driver decide how to do AAI transfers
by Nico Huber 16 Jun '12

16 Jun '12

Currently spi_aai_write() is implemented without an abstraction mechanism for the programmer driver. This adds another function pointer 'write_aai' to struct spi_programmer, which is set to default_spi_write_aai (renamed spi_aai_write) for all programmers for now. A patch which utilises this abstraction in the dediprog driver will follow.
