You're using an incorrect board.bin file.

The qca6164 firmware has extra checks and expectations wrt that file.
If it gets one it doesn't like it crashes (note the 0x000A012D in the
register dump).

You'll need to extract the file from qca6164 windows driver or look
around on the mailing list archive and/or ubuntu launchpad. I'm pretty
sure this was already discussed somewhere..
