serprog with arduino UNO

[Hugo Petrucci]

Hi,
I followed the steps in this link http://flashrom.org/Serprog/Arduino_flasher for write the SST25LF040A flash chip

run first time and asked to specify which chip was using

run specifying the chip, the error not found the chip

follows the commands executed

hugo@hugo-linux ~/flashrom $ sudo ./flashrom -p serprog:dev=/dev/ttyACM0:2000000
flashrom v0.9.6.1-r1701 on Linux 3.5.0-17-generic (i686)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
serprog: Programmer name is "serprog-duino"
Found SST flash chip "SST25LF040A" (512 kB, SPI) on serprog.
Found SST flash chip "SST25VF040" (512 kB, SPI) on serprog.
Multiple flash chips were detected: "SST25LF040A", "SST25VF040"
Please specify which chip to use with the -c <chipname> option.

specified the chip and verbose
