At least use:flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=8000
This improves read/write really!!!!

I have a Pi 3 coming and will definitely give it a try. Have you tried this on a Pi 2?
Thanks for your contribution!

But a little hard to find out the right way to connect the pi to the ic. I had to load the battery full, then i had to power down the pi. With power plugged in the pi i have connected the test clip, pi powers up itself. No other way was working!
