Interfacing 16-bit SDRAM on K65

Question asked by Anton Svensson on Jun 30, 2016

I'm having problems interfacing a 16-bit SDRAM on the k65.

The SDRAM being used is an MT48LC4M16

The SDRAM is connected as in the picture attached.

 

The problem I get is when I try to access the SDRAM, with an 32 bit access not with 16 or 8 bit, and writing the prechargeall command I get some sort of exception and landing at 0x10066958.

 

When accessing with 16/8 bit I won't get any information to the SDRAM, writing and reading all result in 0x0 in values.

 

Anyone had similar problems?

 

Best regards

Anton
