[flashrom] New chip erase function

[M.Altschaeffel at gmx.de]

Hi,
i have a problem with flashing a new blank bios chip. It´s a MX25L3206E chip. 

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found Macronix flash chip "MX25L3206E/MX25L3208E" (4096 kB, SPI) on linux_spi.
Reading old flash chip contents... done.
Erasing and writing flash chip... FAILED at 0x00000000! Expected=0xff, Found=0x00, failed byte count from 0x00000000-0x00000fff: 0xffb
ERASE FAILED!
Reading current flash chip contents... done. Looking for another erase function.

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.
Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom at flashrom.org, thanks!

I started flashrom with : " sudo flashrom -n --programmer linux_spi:dev=/dev/spidev0.0,spispeed=512 --chip "MX25L3206E/MX25L3208E" -f --write /tmp/t430.rom " 

I can´t skip the erase function, my thought -n and -f would help but no difference. 

For any help i would be thankful.

Regards,

max
