Hi all, I am working on 6211 based system. I am trying to boot the DSP through Host. (Host is an intel's RISC processor) After downloading the code to the intenal mem. of DSP thro'h host port, I am writing '1' to DSPINT bit of HPIC register so that DSP wakes up. My problem is: sometimes DSP starts execution and does the intended job and at other times it is not doing it although internal mem. contents are perfectly correct. i.e., once I write '1' to DSPINT, control is hitting at 0th location and starts execution and if I run the same program(from the host) to set DSPINT at someother time it seems control is not at all hitting 0th loc. and the reqired task is not being achieved from DSP. What could be the problem here?? Looking forward to your solutions... Simha __________________________________________________ |

The DSPINT only acts as a "wakeup" signals the first time after a
reset. When the DSP is running DSPINT is a interrupt signal. /Regards, P Ligander simha j wrote: > Hi all, > > I am working on 6211 based system. > I am trying to boot the DSP through Host.
