On F2808 SARAM

Hi all,

On f2808 memory map there are two 8k*16 H0 SARAM, I want to use them in the following way:

1.From address 0x00 A000 to 0x00 C000, this whole area is used for data buffering, all the data from emulator would be stored in this area and plot via ccs graphics, the max data size would  be 8K*16

2.From address 0x3F A000 to 0x3F C000, this area would be used for program debugging

3.I think the f2808 RAM lnk.cmd file has to be modified, how to do that?

4.It would be highly preferred if any one can offer me the ready made f2808 RAM lnk.cmd file for further reference!

 

Thanks!

    Hi Bill,

     

    What you describe is not possible as H0 is one block of physical memory mapped into two address spaces. It has something to do with C24x compatibility mode.You will have to split it into 0x00 A000 to 0x00 B000(or 0x3F A000 to 0x3F B000) for data and 0x00 B000 to 0x00 C0000(or 0x3F B000 to 0x3F C0000
