So, I was looking over the schematics for the ADSP-BF609 EZ-KIT Lite (http://www.analog.com/en/processors-dsp/blackfin/adsp-bf609/products/EVAL-BF609-EZ/eb.html) and there are several instances of a part labelled RNS005 between the DSP and the DDR memory. It looks like some sort of buffer, but what actually is it ? I can't find any reference at digikey (or even with a general google search)
While I'm at it, the docs say
ADSP-BF609 EZ-KIT Lite - The EZ-KIT Lite includes an ADSP-BF609 EZ-Board with standalone debug emulation hardware
Um, what ? What's the 'emulation hardware' if there's a real BF609 on the board ? What's there to "emulate" ? Can this board be used with the non-pay-for tools, or is it just useful to those with CrossCore or VisualDSP++ ?
