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...

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.
