DSC MC56F8357 External memory access problem

Hello community people,

 

I'm working on integrating external data RAM as well as Program flash with the DSC MC56F8357. I use CW 8.0 version for the external memory development. I'm facing problem to map the external memory to the external RAM even though I mapped the address of the data memory correctly as per the memory mapping details. I use CPU properties to configure or initialise the external memory for data RAM as well as external program Flash. I connected the /DS to the data RAM and /PS to the Program flash.

 

Now I'm trying to make the external RAM as my data RAM but its not working even though its configured through CPU properties - > External memory Buses enabled

 

My Current project Settings are given below for your references. I have attached the memory interface also for your reference.

 

Program Memory - Internal

Data Memory - External

Initialise OMR - Yes. (Tried with yes and No )

 

Kindly help me to make the external memory up and running.  All your comments and guidelines/notes are most welcome.

 

Thanks.

 

Regards,

AT T
