Dear Flashrom-Team,
 
Currently, I am trying to progam my Macronix MX25L512E flash chip. Sadly, I always get this error message, where the program can not write to the chip or erase it. The comman was "flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=2000 -w new.bin". 
Here is the error message:

Uh oh. Erase/write failed. Checking if anything has changed.

Apparently at least some data has changed.
Your flash chip is in an unknown state.
