Thank you for the advice.
Now I have been able to insert instructions to display a number on an
attached display which means that I can now see that the code runs until the
file head_4xx.S in the line where the comment is "Now turn on the MMU for
real" and then calls start_kernel by way of an rfi instruction. The
processor then ends up in the Instruction storage exception where I have
placed another write to the display.
Do you have any idea how to find out what happened here?
