The goal is to debug the path from MPU to Altera SPI Core through AXI3 Lightweight bridge.
The Linux is not compiled yet... So, I only have the U-Boot and SignalTap-II for debugging the path...
What are suggestions? What's the best way to debug this path?

Check out page 7:
www.alteraforum.com/forum/newreply.php?do=newreply&p=210842 I suppose you could write some basic bare metal code:

As a warning, make sure that you do NOT read or write to memory spaces that don't exist if using Linux. Those drivers aren't very robust for such issues.
