Reading ADSP-21261 Processor with minimal components

Hi

 

Is it possible to read a SHARC processor ID WITHOUT the SPI flash installed, via the ICE tool ? I developed a custom board and doing basic tests like power and processor communication,  the only components populated are X2 4.7k pull-up resistors (FOR THE JTAG LINE ), is it possible to read the processor with minimal amount of components ?

 

The processor is a ADSP-21261. (also the 25.00MHZ oscillator crystal is NOT connected), So far I cannot communicate with the processor at all.

 

I need this to verify that the power supply and processor is working.
