hello friends, I have inerfaced REALTEK 8019AS to adsp 2181(BDMA). when relatek put in external loopback mode,& when the receive interrupt is disabled(to verfiy the error path),my dsp DM locations get corrupted.(sometimes happens in internal loopback also).This happens at random. my question is 1)why disabling interrupts (PRX)of REALTEK destroys dsp locations?. 2)If i don't get the receive interrupt in the real sense what are the precautions should i follow in software to take care of this situation?. Incase you need further clarifications regarding hardware please feel free to ask. Friendly, Balagopal. |
