[Libreboot] No EEPROM/flash device found

[Alex McGrath Kraak]

Hello.

I am currently trying to flash libreboot to a thinkpad x200 from an arduino.
However i am running into an error when i run the command to flash.
"No EEPROM/flash device found". i have followed the instructions
here[https://optechnoblog.wordpress.com/] and
here[https://www.flashrom.org/Serprog/Arduino_flasher] appropriately.

I understand that using a beaglebone is reccomended, just i cant
really spend the extra 50€ at the moment, and i own an arduino, and
seemingly it is possible to flash libreboot with one.

the command i run in order to flash is:
"sudo flashrom -p serprog:dev=/dev/ttyACM0:115200 -w
x200_8mb_ukqwerty_vesafb.rom -V "

Thanks!
Alex.
