VIA VT6421A
by Magyar Szabolcs 30 Sep '12

30 Sep '12

Hi, I post a success story about a VIA VT6421A based SATA/PATA PCI controller. The flashrom can probe/read/write successfully the onboard PMC Pm49FL004 chip. I downloaded the patch from http://patchwork.coreboot.org/patch/3214/. Just one thing... "BAR type unknown..." I don't known the meaning, but it worked for me without errors. Please add the patch from above to the trunk. I attached a verbose probe output too. flashrom v0.9.3-r1362 on Linux 2.6.38-std220-i586 (i686), built with libpci 3.0.0, GCC 4.3.2, little endian flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. Found "VIA VT6421A" (1106:3249, BDF 00:0a.0). BAR type unknown, please report a bug at flashrom(a)flashrom.org === This PCI device is UNTESTED. Please report the 'flashrom -p xxxx' output to flashrom(a)flashrom.org if it works for you. Please add the name of your PCI device to the subject. Thank you for your help! === Found chip "PMC Pm49FL004" (512 kB, LPC, FWH) on atavia. Reading flash... done. Best regards, Szabolcs Magyar P.S.: Sorry for my english.

2 flashes on SPI bus
by Andrei Dolnikov 23 Sep '12

23 Sep '12

Hello folks, I would like to use a flashrom utility to access 2 serial flashes on the SPI bus of my x86 board, but I'm struggling with the second one. So I'm looking for any help, hints or advices which can help me to solve this issue. I have custom x86 board (Atom n450 CPU, ICH8M chipset) which have 2 serial flashes installed on it. The first one is SST25VF016B and the second one is Numonyx M45PE16. The M45PE16 is pretty the similar to the M25PE16. Both this chips are connected to the SPI bus of the ICH8M chipset, the CS (chip select) signal of the SST25VF is routed to the SPI_CS0 and the CS signal of the M45PE16 is routed to the SPI_CS1. I can successfully read, erase and write the SST flash. Trying to figure out if flashrom utility can find the second Numonyx flash I've added the proper description for it to the flashchips.c (actually I've leaved it the same as for M25PE16 but changed model_id field). Unfortunately it didn't help me at all. So I'm wondering if flashrom can't find M45PE16 flash because of cleared SPI_CS1 signal and how can I enable it? Does flashrom utility support such kind of configurations or does it simply searching for the flash on CS0? Probably some of you have some ideas on enabling SPI_CS1 or even some useful links etc. Unfortunately the official Intel ICH8M documentation looks kind of complicated and no so clear to me. I'll of course digg into it but any help, hints or advices are highly appreciated! Thanks in advance, xborodax.

05 Sep '12

Hi! I'm going to flash Gembird PCI 3SATA+1IDE controller's BIOS, there is W39V040C. I found an excellent professionaly modified ROM for this device. I will try to do it on board of ASUS P4P800E-DELUX. Just let me know, is it possible in the moment or I have to wait for a new version of flashrom.exe? This device have unfriendly relations to Radeon X1600 AGP, on board of ASRock P4i45E MB, so I found only new modified ROM of PCI controller can help. Waiting for Your answer, Alexey.

[PATCH] Hack libpci not to exit(1) during init if PCI does not work
by Carl-Daniel Hailfinger 05 Sep '12

05 Sep '12

This patch is for testing only, and not for immediate merge. libpci unhelpfully calls exit(1) instead of reporting an error if init fails. Fortunately, that part of libpci has not changed since the year 2000, so we can use a really evil hack to avoid that. We supply an alternative error printing function (which does not exit(1)) and this function detects which error is happening and hacks internal libpci structures in a way that avoids a later segfault due to NULL pointer dereference. We MUST absolutely make sure that pci_init() in libpci will not change or this hack will explode spectacularly. Once we decide that this hack is the way to go, notifying the libpci maintainer is essential. Apply this patch, then compile flashrom with make CONFIG_DUMMY=no CONFIG_INTERNAL=o CONFIG_SERPROG=no CONFIG_RAYER_SPI=no CONFIG_NIC3COM=no CONFIG_GFXNVIDIA=no CONFIG_SATASII=no CONFIG_FT2232_SPI=no CONFIG_DRKAISER=no CONFIG_NICREALTEK=no CONFIG_NICINTEL_SPI=no CONFIG_BUSPIRATE_SPI=no CONFIG_OGP_SPI=no CONFIG_SATAMV=no CONFIG_NICINTEL=yes To check if the hack works, run "flashrom -V" and respond to this mail with the output. You should get a message near the end which says that programmer initialization failed.

[PATCH] Add Spi interface support for Tunnel Creek chipset (3)
by Feldschmid, Ingo 30 Aug '12

30 Aug '12

Hi, Last changes I submitted have been vs. trunk 1424. Since there is a new version out, I will resubmit the changes built against the new flashrom trunk version: The Intel Tunnel Creek chipset supports both an SPI and an LPC bus. Set chipset table entry for Tunnel Creek to new function "enable_flash_tunnelcreek", which will read the hardware straps and return support for the bus that has been used for booting. This function uses "ich_init_spi" with ich_generation set to 7 for initializing the SPI bus if necessary. SPI functionality tested on actual hardware (see attached file flashrom.log), Tunnel Creek LPC interface not tested yet (missing hardware for that). The attached patch has been created vs. flashrom trunk 1427.
