So far I've tried the following: 1) The current default in meta-raspberrypi - bootfiles at 56cd7ffb3f7244017c8eb3b492ea37592c678506 and kernel 0ec4154d64ebba48ca2446cde60a90546311defc 2) The above kernel with known-good bootfiles from a Debian SD card 3) The above kernel *on* the known-good Debian SD card 4) Known good kernel with the above bootfiles 5) The combination you suggested above 6) The latest available kernel + bootfiles Of those, only option 4 sort-of worked. > BTW - you need to update the .conf file for the machine to use ttyAMA0 if > you want to use the serial port for kernel debug. I did that, however it's not going to be much help as I don't yet have a serial cable (I have one on order). I'm beginning to wonder if it's something about the way the kernel is being built. Are you using denzil or master of Poky?/OE-core?
