Changing it does not influence functionality. If you are in a hurry skip this paragraph. :) I am a bit puzzled at the moment regarding the (read) log. If you look at the detailed output of the contents of the status register at line 132 ff. you see that flashrom (mistakenly) reads 0xFF, which leads to the assumption that a block protection is enabled (see bottom of page 26 in the datasheet of the chip; that's quite a standard layout of a SPI flash status register...). It then tries to disable the "protection" and fails because another bit in the status register - the WIP bit - remains at 1. I have no idea why it (always) reads 0xFF from the status register... I have checked the opcode and it is correct, and there is nothing fancy about... apart from one thing I just noticed which you could test: in spi_read_status_register() in spi25_statusreg.c replace 2 with 1 in the array declaration readarr[2] so that this line becomes unsigned char readarr[1]; /* JEDEC_RDSR_INSIZE=1 but wbsio needs 2 */ wbsio is our driver for a very annoying winbond SPI master and as the fixme in the function says, this hack should not be in the generic code. If the macronix chip does not repeat the status register contents when one reads more than one byte after sending the RDSR (read status register) opcode (which chips usually do) but 0xFF then we have found the culprit. PS: please send further mails to flashrom(a)flashrom.org - our mailing list, thanks. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

[PATCH] Add git support to the Makefile
by Carl-Daniel Hailfinger 21 Aug '13

21 Aug '13

flashrom relies on svn to export tarballs and only prints the last svn revision in the version message even if flashrom is in a git tree. Print extended version information (version, svn revision, git hash, repository URL). Allow exporting from git trees. This should make git users first-class citizens like svn users.

Hi Vadim, thanks for your mail. I have added the flashrom mailing list in CC: because we should develop a generic way to handle DualBIOS and similar techniques.

It will help us make a flashrom design decision that works for all boards with multiple flash chips. By the way, some of us have good contacts at ITE, so we can ask ITE for details about the undocumented registers. Regards, Carl-Daniel -- http://www.hailfinger.org/

The restricted opcode is not so unusual. We have encountered the same with some thinkpads. Vendors don't need proper RDID because they usually know which chip is installed so they don't have to support 300+ chips like flashrom does.

The protected regions are a bigger problem. This configuration protects almost the complete BIOS region and this can not be disabled at runtime. Does the vendor offer updates for the BIOS? Did you look into the BIOS configuration menu if there is a switch to allow BIOS modifications? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Thanks! This means my code works well. The following timings are straight from the W25Q32BV datasheet. They may be completely unrealistic. Typical erase time for that chip is around 30 seconds for a sectorwise chip erase (without overhead). The typical write time for that chip (using 5-byte chunks due to the short FIFO for SB600) would be around 600 seconds. Typical write time for that chip with the long Kabini FIFO would be 45 seconds. Add initial read time, sectorwise chip erase time, erase-verify time (full chip read), write time, write-verify time (full chip read) and the write time suddenly looks pretty reasonable. Most important for me was to get the FIFO pointers right for Kabini. Speed issues can be dealt with after the flashrom 0.9.7 release (right now I'm just trying to fix things). That said, the datasheet is rather unclear about the effect of UseSpi100=1, and I'd like to set it to 0. By the way, the data which enabled me to fix the FIFO stuff for Kabini (because the datasheets have room for improvement) is here: http://paste.flashrom.org/view.php?id=1718 Regards, Carl-Daniel -- http://www.hailfinger.org/
