ADSP-21489 booting problem

Hello,

after RESET processor reads M25P16 flash memory over SPI, but without initial 'read' command ($03) on MOSI line.

What could be causing this error ?

I am sure, that this must be HW error, but have already checked, many times, schematic of my board and ADSP-21489 signals using osciloscope without effect.

 

Regards

Roman
