I am using a ADSP 2181 KST133 Rev 0.2 and I am trying to boot from an external EPROM (MMAP=0,BMODE=0). The DSP only activates the address bus and the BMS signal at reset. The BMS signal stays high. Another effect is that at CLKOUT no signal is at reset. I think that the PLL doesn't lock altought the reset time is longer than 2000 CLKIN cycles. The DSP only makes garbage also after a second reset. Are these problems effects of the low Revision number or is there anything else I have to consider? Regards Rainer Rupp |
