I am not getting any data from Sigma, when i try to read data from a memory location through SPI

 

The following procedures were done

- MCLK =12 Mhz

- made the reset (pin 24) high ,

-To make Sigma in SPI mode three dummy Spi writes are done

-Soft reset performed by writing to 0xF890

-To write data was sent as "0x00 <Memory Address> <Data>"

-To read data was sent as "0x01 <Memory Address>"

 

Is there any error in my approach? Baud rate is 4Mhz

Please suggest a way to check if DSP is working...
