Thankyou very much , I have download the source code and study it .The flash method I can understand ,but I confused with the mechanism about windows it used .
I will try my best to understand it.
I have some problem in my compile process. There is something wrong ...
make -C libpci
make: Entering directory `/home/new/winflashrom/libpci'
make: Nothing to be done for `all'.
make: Leaving directory `/home/new/winflashrom/libpci'
gcc -Os -Wall -Werror -DDISABLE_DOC -c -o udelay.o udelay.c
cc1.exe: warnings being treated as errors
udelay.c: In function `myusec_calibrate_delay':
udelay.c:24: warning: implicit declaration of function `gettimeofday'
make: *** [udelay.o] Error 1
If I deleted line 24 and 26 in udelay.c of `gettimeofday', the build process will success and create flashrom.exe.
How can i fix it ? I thought the fault is my version of the build environment .I don't honw why i couldn't download the latest version from http://mingw.sourceforge.net/
