ADSP-21489 SDRAM setup

Hello,

 

I'm having problems interfacing my ADSP-21489 with SDRAM MT48LC16M16A2-7E, in my custom board. I have been reading EE-286 and configured the Sharc registers, but i can't write or read correct words from SDRAM. I verified the connections between DSP and SDRAM and everything seems ok.

 

My code is attached. The link to MT48LC16M16A2 datasheet is here.

 

Can anyone see if I'm doing anything wrong?

 

Best Regards,

 

Pedro Pinto
