Fwd: Re: Cannot compile flashrom for windows
by Bio 09 Feb '16

09 Feb '16

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, -------- Message transféré -------- Sujet : Re: [flashrom] Cannot compile flashrom for windows Date : Wed, 3 Feb 2016 02:31:54 +0100 De : Zak <zackwarrior(a)gmail.com> Pour : flashrom(a)flashrom.org 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...

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. > Anyway i installed mingw and used msys64 to get all the packages and > update everything correctly, i also put the libusb and libftdi in the > bin, lib and include directory, i think everything is installed > correctly but... > When i try to compileflashrom with make i get this error > $ make > Files don't seem to be under version control.

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. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Cannot compile flashrom for windows

Hello, I'm having trouble with flashrom, i have a working ft2232 board and i correctly connected a spi flash on it on port A I also correctly installed the libusb drivers for the board So i found a compiled version of flashrom for windows v0.9.6.1-r1705 I run it with this command flashrom -p ft2232_spi:type=2232H,port=A And i get this: flashrom v0.9.6.1-r1704 on Windows 6.1 (x86) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically. I then decided to try port B, so i wired the flash chip on port B and used this command flashrom -p ft2232_spi:type=2232H,port=B And i get this: flashrom v0.9.6.1-r1704 on Windows 6.1 (x86) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop...

That would mean that you try to write a 4 kB file to an 8 MB flash chip. flashrom won't allow that for good reasons. It seems like you are confusing two files IMHO. The 4 kB file is probably just the flash descriptor but that alone is probably not what you want to write. > and when i go to the properties of the image it is similar to > the chip's size. I certainly doubt that. It is more likely that you are comparing something else than flashrom does (i.e. you are looking at the wrong file). > Have tried using hex editor on windows and flashing that > format but keep getting same error message, hope you can help me with > regard to this, thankyou. You probably want to use a pre-built image by John Lewis. They should have the correct size... -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
