I've been continuing to look into why things aren't working.

I believe the diagnostic output was due to jumping into the 'wrong' places.

When I objcopy out a binary image, load that, the use the u-boot 'go' command at 1000000, there is nothing that is output
to the console.

I've checked and believe a FDT file is statically linked into the code, and it seems to match up with the p1020rdb.dts, with a few
differences due to the 'wlan' version. However, the serial ports are the same, as well as various memory and other devices.

One thing that did occur to me was the default speed of the serial port as a console. My u-boot is setup for 115200, but I did try
9600 and 19200, just in case someone took the lowest speeds (these days...). But still no output.

I did disassemble the kernel... verified that there's the some what expected startup code, which was setting up an initial translation table, then a call the 'booke_init'.

You indicated a bug in 'head' for booke_init.c... what are the symptoms? And where to get a fixed version?

If you have other ideas I'd appreciate them as well.

Thanks,
