Hello,

Did you get have time to check my last message ?
I was wondering if you know why i still get an error on last version when trying to open port B
And to make flashrom detect and read/write my flash, i know that i must add my flash into flashchips.c
After reading the data sheet of my flash MX25L25635F i understood that the 24 bit address protocol of Flash can only access up to 128Mb this is why 32bit is needed.
The thing is i only need to access the first 128Mb (in fact i really only need the first 32Mb to be exact), buy using the 24 bit adresse protocol i should be able to read that no ?

Sorry again for the questions, i'm doing a lot of reading and trying to understand all this and i just need someone to tell me if i'm going in the right direction or not


Best Regards,

Hi there,

First thanks for your reply, helped me out on where to look, it was libftdi
So after doing some research here and there, it looks like the libftdi was not installed right (even tho all the files were in the correct place), anyway by doing a libftdi.pc and pointing to the files i was able to compile the last version of flashrom
But i get the same thing problem...

Microsoft Windows [version 10.0.10240]
(c) 2015 Microsoft Corporation. Tous droits réservés.

C:\flashrom>flashrom
flashrom v0.9.8-r1888 on Windows 6.2 (x86)
flashrom is free software, get the source code at http://www.flashrom.org

Please select a programmer with the --programmer parameter.
Previously this was not necessary because there was a default set.
Valid choices are:
dummy, ft2232_spi, serprog, buspirate_spi, pony_spi, usbblaster_spi,
pickit2_spi.

C:\flashrom>flashrom -p ft2232_spi:type=2232H,port=A

Calibrating delay loop... OK.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

C:\flashrom>flashrom -p ft2232_spi:type=2232H,port=B
flashrom v0.9.8-r1888 on Windows 6.2 (x86)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Unable to reset FTDI device (USB device unavailable).
Unable to set latency timer (USB device unavailable).
Unable to set bitmode to SPI (USB device unavailable).
ftdi_write_data: -666, USB device unavailable
Error: Programmer initialization failed.

Anyway now that i got it compiled and since it looks like port A works and not port B? i guess ?
Could you give me advices on how to make flashrom work with my flash chip MACRONIX_MX25L25635F?
I need to modify and add the informations to flashchips.c? What about the 24 and 32bits difference?

Thanks again for your help
Best Regards

That does not tell much... the suspicion you wrote further below is
correct.

That looks a bit fishy but might have been fixed in the meantime. I
would like to see the output for the same command line with a current
version...

Yes, indeed. And the current one won't help you either. The problem is
that this chip requires 32 bit addresses instead of the 24 bit address
used up to now in SPI flash chips. flashrom does not support this yet
and so supporting your chip is not feasibly right now. There exist some
patches though that would make it work.

I don't see an error. The pkgconfig message is not an error..

Sounds like a bug in mingw or libusb to me... cross-compiling with
mingw under Linux for Windows should work fine since a long time ago.
