Hey, I'm thinking about upgrading my BIOS and found "flashrom" in DEBIAN-repositories. Running a "read" on the builtin BIOS I saw the request for sending you some information - so here you are. Does "guesswork" mean, it might be unsafe to use this software on this board/bios? Thanks for your work! Greetings, Volker This ist the requested output flashrom v0.9.6.1-r1563 on Linux 3.13-3.slh.2-aptosid-686 (i686) flashrom is free software, get the source code at http://www.flashrom.org flashrom was built with libpci 3.1.9, GCC 4.7.1, little endian Command line (3 args): flashrom -V -p internal Calibrating delay loop...

According to your log the software write protection is enabled (and the parsing of the raw value 0x0c seems to be correct, so this is not only a cosmetic problem). Did you change anything since you wrote to the chip? Regarding the cable lengths: The troubleshooting section of the bus pirate wiki page links to this: http://flashrom.org/ISP and the first problem mentioned there are too long cables ;) -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Tested AT25DF161

Hello I tested for cleaning work, reading, writing, memory AT25DF161 using Bus Pirate v4. Used: flashrom v0.9.6.1-r1704 on Windows 6.1 (x86) flashrom was built with GCC 4.7.2, little endian Baud rate is 115200. Detected Bus Pirate hardware v4 Detected Bus Pirate firmware 6.2 ("v6.2-beta1") Using SPI command set v2. SPI speed is 8MHz Raw bitbang mode version 1 Raw SPI mode version 1 The following protocols are supported: SPI. Probing for Atmel AT25DF161, 2048 kB: probe_spi_rdid_generic: id1 0x1f, id2 0x4602 Found Atmel flash chip "AT25DF161" (2048 kB, SPI) on buspirate_spi. Ignoring security lockdown (if present) Ignoring status register byte 2 Chip status register is 0x0c. Chip status register: Sector Protection Register Lock (SRPL) is not set Chip status register: Bit 6 is not set Chip status register: Erase/Program Error (EPE) is not set Chip status register: WP# pin (WPP) is asserted Chip status register: Software Protection Status (SWP): all sectors are protected Chip status register: Write Enable Latch (WEL) is not set Chip status register: Write In Progress (WIP/BUSY) is not set === Initially, there was a problem with the use of long cables (> 20 cm). After verification of the firmware did not pass. Replaced wires from Bus Pirate at length (10cm), all turned out. Many thanks for the utility. I think that you can remove the status UNTESTED with this chip. Thank you again. I think it is reasonable to point out the page on the wiki that the length of wire for the Bus Pirate is very desirable <= 10 cm, to avoid many mistakes. This saves the trouble of starting recording, reading chips. Sorry for my bad english, I'm from Russia. -- С уважением Алексей
