Hi Sir ,
Main DSP used Flash leading , then leading the DSP by SPI bus . how can the multiprocessor share the Flash and EPRom ? could you send us some file about it ? thanks .
Best regards ,
Shared memory support is only available in ADSP-21368 SHARC processors. This support is not available in ADSP-21262 processors. Also note that AD0-15 of the parallel port in ADSP-21262 are driven low during and after reset and when you connect AD0-15 lines to the same SRAM that would cause contention on the external memory bus.
Hope that clarifies.
