I think we have the answer :)

I tried v10 which has more options when using RUN from the GUI - allowing you to check 'Download ELF' and 'Start processor' separately.

It is only necessary to check the 'Start processor' option for RUN to go from 'power on' to running - without any apparent downloading.

However, taking the command line(s) from the transcript and running it from a terminal window does not start the processor.

The GUI interacts with the JTAG UART making stracke (http://www.alteraforum.com/forum/member.php?u=27030)'s suggestion of disabling the LOG port look a strong possibility, although the Log port was already set to 'none' in the BSP Editor.

but setting Stdin, Stdout and Stderr all to 'none' does allow the processor to run at power up.

I'm very relieved to be able to get back to real development again - thanks to all of you for you help.
