flashrom ignoring ROM layout region
by John Gainsborough Feb. 5, 2013

Feb. 5, 2013

With BusPirate (v3a, firmware 5.10) and flashrom (v0.9.5.2, little endian) I am attempting to read a region of the flash ROM defined by a ROM layout file as in: flashrom -p buspirate_spi:dev=/dev/ ttyUSB0,spispeed=200k -l romlayout -i region1 -r read file Where file romlayout contains: 003f0000:003fffff region1 The flash ROM IC is correctly identified, and region1 is listed as being used, however flashrom then proceeds to read all ROM memory, not just the area defined by region1. I have run this procedure with flash ROMs: Eon EN25Q32 and EN25Q64. also Micronix MX25L6445 Eventually I plan to use this procedure for writing to a defined region. Any help/suggestions gratefully received. John G

flashrom OPCODES for SPI
by Николай Николаев Feb. 5, 2013

Feb. 5, 2013

Hi Stefan Sorry but i don't want disprove you, i just have a many free time and i want to improve this project. But the dispute burning truth. 8) All time from my last mail i'm searching spi flash chips documentation and I found about 445 chips different brand and sorted them. May be it will be useful for all community. We will made host with SPI(Parallel and other) flash chips documentations and add link on wiki page. for example Eon EN25Q64(link to pdf) 8192 SPI ? ? ? ? 2.700 3.600 Studied documentation i regularity see that all chips has a support standard OPcodes like this WR DATA 0X02 READ DATA 0X03 WR DIS 0X04 READ STATUS 0X05 WR ENA 0X06 ... exclude 10 Atmel chips from amount 445 and for him we will must write special driver and special OPcodes like a Fast Dual read 0x3B Auto Address increment 0xAD and others - that codes is a different fetches spi flash chips What does this mean. This mean that a spi controller has a standard OPcodes for all flash chips and special OPcodes for each one flash chip. But if we will change flash chip on other flash chip with different special OPcodes that we will must replace special OPcodes. If we will not do it that we can't use special OPcodes, but we can use standard OPcodes. So, for more compatibility we will must verify - Does flash chip support special OPcodes?. And if chip will support them that we will use them, but if chip will not support them that we will use a standard OPcodes. for example: MX25L6405 The function write chip used standard OPcodes flash chip called function spi_chip_write_256 SST25VF016B The function write chip used fetches OPcodes flash chip called function spi_aai_write If we can't change OPcodes in registers our SPI controller that we will not write data to chip if we replace them. But we will make a program check supporting OPcodes and switch a function from spi_aai_write on spi_chip_write_256 After that we can easy write to flash or fast - our SPI controller has supporting fetches OPcodes or slow - our SPI controller hasn't supporting fetches OPcodes Also i want to suggest exclude from struct flashchip {} parameters voltage, name and add array of struct like a chipdata. The struct chipdata contains information about all possible chip names and various parameters Because looked chips documents i see chips that have a one model_id but have a various chips name, various voltage and various capacity for example MX25U6435F and MX25L6439E MX25L12805D and MX25L25835E .... -- With best regards Nikolay Nikolaev С Уважением Николаев Николай

by Антон Кочков Feb. 4, 2013

Feb. 4, 2013

Hello! Here is simple diagram for booting flow of modern Intel laptops. Feel free to ask questions, request for improvements, giving hints. Why Intel? Just because it is more complex than modern AMD systems. Why laptop? Same reason - more complex than desktop. If you have an idea howto merge laptop and desktop booting in one diagram - please share. Attaching both png result and MS Visio 2010 source. Best regards, Anton Kochkov.

[commit] r1648 - trunk
by repository service Feb. 3, 2013

Feb. 3, 2013

Author: stefanct Date: Mon Feb 4 05:38:42 2013 New Revision: 1648 URL: http://flashrom.org/trac/flashrom/changeset/1648 Log: Fix building for MacOSX. - Add a new macro named IS_MACOSX to hwaccess.c and use it to enable iopl(). This was broken since r1638. This fix does *not* restore the very permissive concept where iopl() was activated in an #else branch that was inplace before r1638. - Make printing the image file's size in flashrom.c platform independent. Bonus: remove definitions of off64_t and lseek64 which are not necessary anymore for about 1000 commits. Thanks to SJ for reporting the issue and testing the solution.

Hey, a few days ago I successfully flashed an ASUS M5A97 bios (version 0705 to 1605). No problems whatsoever, whereas the BIOS-builtin "AZ Flash 2" turned out to be useless: it didn't even recognize my FAT usb stick. $ sudo /usr/local/sbin/flashrom --programmer internal -w M5A97-ASUS-1605.ROM flashrom v0.9.6.1-r1646 on Linux 3.7.5 (x86_64) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. Found chipset "AMD SB7x0/SB8x0/SB9x0". Enabling flash write... OK. Found Winbond flash chip "W25Q32" (4096 kB, SPI) at physical address 0xffc00000. Reading old flash chip contents... done.

[PATCH] Fix evil twins of Macronix MX25L1605, MX25L3205, MX25L6405.
by Stefan Tauner Feb. 2, 2013

Feb. 2, 2013

Similarly to the previous patch this one updates the chips identified as above with references to and data about their respective twins. Unlike previously this one deals with the more evil details. Helge Wagner from GE discovered some problems with chips sharing IDs and proposed a patch to tackle (some of) them, see: http://patchwork.coreboot.org/patch/3709/ That patch was bitrotting in our mailboxes for a long time and it is still not ready for merge, but we increasingly get reports about problems (e.g. http://paste.flashrom.org/view.php?id=1525) regarding these chips and hence must act to ensure users' safety. This patch splits the chip definitions of evil twins into separate ones which correctly declare the respective attributes (the main problems are the erase block sizes for the 0x20 opcode and hence my changes combine different chips with partly different attributes apart from their names as long as the erasers layout it the same). This forces the user to select the (right) chip definition with the -c/--chip parameter and hence will break a number of previously perfectly working environments. 0x2015 is used by and split to - MX25L1605 (64kB sectors in 0x20 erases) - MX25L1605A (4kB in 0x20 erases and an additional 0x52 opcode with 64kB blocks) - MX25L1605D/MX25L1608D (4k sectors in 0x20 erases) 0x2016 is used by and split to - MX25L3205, MX25L3205A (64kB 0x20) - MX25L3205D/MX25L3208D (4kB 0x20) - MX25L3206E (4k 0x20, 64k 0x52) 0x2017 is used by and split to - MX25L6405 MX25L6405D (64k 0x20) - MX25L6406E/MX25L6436E (4k 0x20) - MX25L6445E (4k 0x20, 64k 0x52) Bonus: add some minor details to MX25L1635D, MX25L1635E, MX25L3235D, MX25L12805D. Signed-off-by: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at> --- TODO after merging this: - implement probing methods that are able to distinguish at least some of the evil twins. - where this is not possible discuss alternatives like the somewhat fail-safe spi_block_erase_20_4or64k() by Helge - find and spank the ones reponsible for this whole mess. --- flashchips.c | 270 +++++++++++++++++++++++++++++++++++++++++++++++++++++----- flashchips.h | 8 +- 2 files changed, 252 insertions(+), 26 deletions(-) diff --git a/flashchips.c b/flashchips.c index b976ee6..1783fe7 100644 --- a/flashchips.c +++ b/flashchips.c @@ -5270,10 +5270,45 @@ const struct flashchip flashchips[] = { .block_erasers = { { + .eraseblocks = { {64 * 1024, 32} }, + .block_erase = spi_block_erase_20, + }, { + .eraseblocks = { {64 * 1024, 32} }, + .block_erase = spi_block_erase_d8, + }, { + .eraseblocks = { {2 * 1024 * 1024, 1} }, + .block_erase = spi_block_erase_60, + }, { + .eraseblocks = { {2 * 1024 * 1024, 1} }, + .block_erase = spi_block_erase_c7, + }, + }, + .printlock = spi_prettyprint_status_register_default_bp2, /* bit6: error flag */ + .unlock = spi_disable_blockprotect, + .write = spi_chip_write_256, + .read = spi_chip_read, /* Fast read (0x0B) supported */ + .voltage = {2700, 3600}, + }, + + { + .vendor = "Macronix", + .name = "MX25L1605A", + .bustype = BUS_SPI, + .manufacture_id = MACRONIX_ID, + .model_id = MACRONIX_MX25L1605, + .total_size = 2048, + .page_size = 256, + .feature_bits = FEATURE_WRSR_WREN, + .tested = TEST_OK_PREW, + .probe = probe_spi_rdid, + .probe_timing = TIMING_ZERO, + .block_erasers = + { + { .eraseblocks = { {4 * 1024, 512} }, - .block_erase = spi_block_erase_20, /* This erase function has 64k blocksize for eLiteFlash */ + .block_erase = spi_block_erase_20, }, { - .eraseblocks = { {64 * 1024, 32} }, /* Not supported in MX25L1605 (eLiteFlash) and MX25L1605D */ + .eraseblocks = { {64 * 1024, 32} }, .block_erase = spi_block_erase_52, }, { .eraseblocks = { {64 * 1024, 32} }, @@ -5286,10 +5321,45 @@ const struct flashchip flashchips[] = { .block_erase = spi_block_erase_c7, }, }, - .printlock = spi_prettyprint_status_register_default_bp3, /* TODO: check */ + .printlock = spi_prettyprint_status_register_default_bp2, .unlock = spi_disable_blockprotect, .write = spi_chip_write_256, - .read = spi_chip_read, + .read = spi_chip_read, /* Fast read (0x0B) supported */ + .voltage = {2700, 3600}, + }, + + { + .vendor = "Macronix", + .name = "MX25L1605D/MX25L1608D", + .bustype = BUS_SPI, + .manufacture_id = MACRONIX_ID, + .model_id = MACRONIX_MX25L1605, + .total_size = 2048, + .page_size = 256, + .feature_bits = FEATURE_WRSR_WREN, + .tested = TEST_OK_PREW, + .probe = probe_spi_rdid, + .probe_timing = TIMING_ZERO, + .block_erasers = + { + { + .eraseblocks = { {4 * 1024, 512} }, + .block_erase = spi_block_erase_20, + }, { + .eraseblocks = { {64 * 1024, 32} }, + .block_erase = spi_block_erase_d8, + }, { + .eraseblocks = { {2 * 1024 * 1024, 1} }, + .block_erase = spi_block_erase_60, + }, { + .eraseblocks = { {2 * 1024 * 1024, 1} }, + .block_erase = spi_block_erase_c7, + }, + }, + .printlock = spi_prettyprint_status_register_default_bp3, /* bit6: CP mode */ + .unlock = spi_disable_blockprotect, + .write = spi_chip_write_256, + .read = spi_chip_read, /* Fast read (0x0B), dual I/O supported */ .voltage = {2700, 3600}, }, @@ -5301,7 +5371,8 @@ const struct flashchip flashchips[] = { .model_id = MACRONIX_MX25L1635D, .total_size = 2048, .page_size = 256, - .feature_bits = FEATURE_WRSR_WREN, + /* OTP: 64B total;

Hello David, in general the chipset as well as the flash chip are well supported by flashrom. The Intel chipsets can however be configured to restrict flash access very firmly. There are various ways to restrict it (forbidden opcodes, write- and read-protected addresses ranges of different kinds etc.). If the board does not set up too many restrictions, flashrom will work for you without problems. The "error" (it is a warning actually, and you can and should read about the details in the man page how to force flashrom to continue) is because the SMBIOS/DMI table in the firmware indicates that it is a mobile device and those sometimes behave in dangerous ways. This is especially the case if the flash chip is not attached to the southbridge but and EC which is sitting between the southbridge and the flash chip. You should also update to a newer version, 0.9.4 is pretty old and I have done quite some work on the intel-related code. When you found out how to tell flashrom to continue even though it thinks it is running on a laptop please send us the output of flashrom -p internal -VV I can then tell you some details about the restrictions set up in the current firmware. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
