Hello, All, I want design with the IDMA interface of ADSP-2187, my circuit send out the signals to ADSP, the waveform is just be same as the data sheet. I hope I can write/read the PM and DM. But: After power on, no matter what I write to DM/PM, then I try to read back the data I write to DM/PM, the return data is not the data I write to, and any location of PM/DM I read out is the same error data. The return data does not change even when I try to reset the DSP chip, it change only when I turn the power of DSP chip off then on. Is there anybody ever meet such a strange thing? -- Eric Chan < |
