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. -- Viele Gr��e Philipp Drewes Reply by mail sticking "philipp.drewes" in front of "tu-harburg.de".

I'm having the same problem. Did you ever find a solution?>Hello, >I have a problem host booting my SHARC 21161 Multiprocessor system.
