SHARC 21161 Booting problem

Started by Philipp Drewes March 26, 2005
Hello,
I have a problem host booting my SHARC 21161 Multiprocessor system. I get
System hangs due to a HBG# hang each time I download the loader file
generated with the Visual DSP environment. The same code just runs fine out
of an EEPROM (I ensure to use a different bootloader for those two tasks).

The ADSP 21161 Hardware Reference states that you can get those hangs
writing to a non existent IOP register. (HR ed3: p. 7-55) So far I used
0x04 wich is directly assoiated with the EPB0.

As I said, I use a multiprocessor system. I wonder wheater I can also use
the muliprocessor memory space to boot my processors.
Is writing to 0x10 0004 equal with writing to 0x00 0004 using CS001# in both
cases? May a HBG# hang result from such a write? 

What other reasons could cause those hangs? It is really difficult to debug
as the hangs are not deterministic.

Thank you for any hints.

I'm having the same problem.  Did you ever find a solution?
