Thank you for the advice.<br>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.
<br>Do you have any idea how to find out what happened here?<br>cheers<br>Peter<br><br><br><div><span class="gmail_quote">On 9/12/06, <b class="gmail_sendername">Andrei Konovalov</b> <<a href="mailto:akonovalov@ru.mvista.com">
