I just monitored the data from the Kindle with my scope and sure enough, No data after the Kernel boot as in post 11. I also checked the 1.8 volt supply for the K3 and it doesn't change very much. I could try using an external 1.8 volt suppy though. Looking at the video again it looks like there is a (b) in the 'program callout' portion of the port setup?? See attached picture.
