Writes have been disabled for safety reasons. You can enforce write support with the ich_spi_force programmer option, but you will most likely harm your hardware! If you force flashrom you will get no support if something breaks.

Rayer_SPI and xilinx buffered dlc5 cable
by Andrew Tarabaras 25 Feb '13

25 Feb '13

Hi, Just a heads up that the rayer_spi module wont work with a buffered xilinx DLC cable. There is a pull down buffer in the MISO ( Data In ) line which is enabled when pin 6 of the parallel port is pulled low. I dont have time to be submitting patches, fix it or not I dont mind. These are the changes I made. Global var static int rayer_pulldown_bit = 4; in rayer_spi_init() after rget_io_perms(); val = 1; lpt_outbyte &= ~(1 << rayer_pullup_bit); lpt_outbyte |= (val << rayer_pullup_bit); OUTB(lpt_outbyte, lpt_iobase); Cheers, hope it will help stop someone else spending hours debugging something that doesn't work.

[PATCH 3/3] Allow physmap_common() to round address ranges to page boundaries.
by Stefan Tauner 22 Feb '13

22 Feb '13

Automatically round address ranges requested from rphysmap() to page boundaries. Other physmap() variants were not changed so this is safe regarding unmapping. I had also to shorten the readbility defines for the physmap_common parameters to make the calls fit a single line.

[PATCH 2/3] uintptr_t-ify physmap.c.
by Stefan Tauner 22 Feb '13

22 Feb '13

unsigned long is not the right type for manipulating pointer values. Since C99 there are suitable unsigned and signed types available, namely uintptr_t and intptr_t respectively. Use them in physmap.c where applicable. This should be done in a lot of other places in flashrom too, but that's a huge pile of work and we better start it with a small step than never (which is the forseeable alternative ;) This patch also changes the display width of all address values in physmap.c to 16/8 hex characters depending on the architecture.

Compaq Evo D510 SFF - Erase Failed
by Justin Chevrier 22 Feb '13

22 Feb '13

Hi Guys, Attached are logs from a failed attempted erase of the flash rom on the system listed in the subject. I was able to verify the flash against the backup I had taken and the system was able to successfully reboot, so it appears no changes were made. It appears this system is using a nonstandard chassis type ("Space-saving") and the: "laptop=this_is_not_a_laptop" is required for Flashrom to interact with the system. HP doesn't specify any particular process (jumper, setting in BIOS) required to update the BIOS on this system (that I could find). Direct link to BIOS: ftp://ftp.hp.com/pub/softpaq/sp23001-23500/sp23350.exe Downloaded file can be extracted via 7zip, then the resulting ROM.CAB file can be extracted as well resulting in 'Rom.bin' that matches the size of the chip. 7z x sp23350.exe 7z x ROM.CAB Thanks, Justin

Hello, Just tested this EPROM and it's writing, reading, erasing great. Thanks, and Best Regards, root@server:~# flashrom -p rayer_spi -w binary.bin flashrom v0.9.5.2-r1517 on Linux 3.2.0-37-generic (x86_64), built with libpci 3.1.8, GCC 4.6.3, little endian flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. Found Eon flash chip "EN25Q64" (8192 kB, SPI) on rayer_spi. === This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE The test status of this chip may have been updated in the latest development version of flashrom. If you are running the latest development version, please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash part. Please include the flashrom output with the additional -V option for all operations you tested (-V, -Vr, -VE, -Vw), and mention which mainboard or programmer you tested. Please mention your board in the subject line. Thanks for your help! Reading old flash chip contents... done. Erasing and writing flash chip... Erase/write done. Verifying flash... VERIFIED.

[PATCH] Add utility to print all chip names in flashchips.h that are not in flashchips.c.
by Stefan Tauner 22 Feb '13

22 Feb '13

This allows to list yet unsupported chips easily. First it tries to find the directory containing the files, then it uses sed to extract the macro names of chips from flashchips.h, greps for them in flashchips.c and prints it if it is not found. If verbose mode is activated by giving at least one additional parameter it prints the comment following the macro definition too.
