[quote user="Ernast Sevo"]With regards to 4 what are the steps necessary for defining executing this ( defining a memory address greater that 0x1100 0000 and mapping it to our CS2 physical address of 0x0200 0000) ?[/quote]
It's part of the configuration:
{
10, /* ENTRY : Entry number */
"CS2", /* NAME : Name of the memory region */
0x02000000, /* ADDRPHYS : Physical address */
0x02000000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if known) */
0xFF, /* SIZE : Size of the memory region */
FALSE, /* SHARED : Shared access memory? */
FALSE /* SYNCD : Synchornized? */
},
In the above configuration you've defined ADDRPHYS and ADDRDSPVIRT as the same address. You simply need to change ADDRDSPVIRT to be something larger than 0x11000000 and then use that address in the DSP code to access your chip select.
