I had to add this to the config.txt on my pi:
then enable spi programming using raspi-config.
Everything else in the tutorial worked fine. Got my Linx10 back up running.
Only problem I have now is no +5v on any of the USB interfaces (I have to use a powered hub to connect anything now, and the origami keyboard doesn't work)
Many thanks for this. I will also take your idea for keeping a pi for flash programming
since I have an old PI
