Hi,
Have you done this:
* Ensure that the RESETVECTOR field in LINKCFG_dspObjects structure is also
changed to point to the right place.
STATIC CONST LINKCFG_Dsp LINKCFG_dspObjects [] =
{
{
...
0x84100000, /* RESETVECTOR : Reset Vector for the DSP */
...
}
}
Regards,
Mugdha

Subject: Re: Changing the default memory map on DM6446
I forgot to mention that when I load DSP executable I get the following message:
Error: DSP-side memory map does not match configuration.
Compare DSP-side TCF/MAP file with /dsplink/config/all/CFG_<PLATFORM>.c

Benjamin,
The MAR bits are simply to allow caching of the DDR region. Each bit stands
for 16MBytes of external memory. 1 would indicate that region should be cached
in L2 and 0 would disable caching. The 128to159 indicates this is for the
128th to 159th 16MB chunk in external memory which started from 0x80000000.
Hence set it according to which region of DDR you wanted cached by the DSP.
Generally this is the region where codec data memory resides [DDRALGHEAP].

Omkiran

Hi all,
I am working on a custom DaVinci DM6446 board. I have been trying to change the
default memory map to allocate more memory for DDR2 on the DSP side but without
any luck. My application is running without codec engine.
My default DSPLink configuration is: STATIC CONST LINKCFG_MemEntry
LINKCFG_memTable_00 [] =
{
{
0, /* ENTRY : Entry number */
"DSPLINKMEM", /* NAME : Name of the memory region */
0x8FE00000, /* ADDRPHYS : Physical address */
0x8FE00000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0x5000, /* SIZE : Size of the memory region */
TRUE /* SHARED : Shared access memory? */
},
{
1, /* ENTRY : Entry number */
"DSPLINKMEM1", /* NAME : Name of the memory region */
0x8FE05000, /* ADDRPHYS : Physical address */
0x8FE05000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0xFB000, /* SIZE : Size of the memory region */
TRUE /* SHARED : Shared access memory? */
},
{
2, /* ENTRY : Entry number */
"RESETCTRL", /* NAME : Name of the memory region */
0x8FF00000, /* ADDRPHYS : Physical address */
0x8FF00000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0x00000080, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
},
{
3, /* ENTRY : Entry number */
"DDR2", /* NAME : Name of the memory region */
0x8FF00080, /* ADDRPHYS : Physical address */
0x8FF00080, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0xFFF80, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
},
{
4, /* ENTRY : Entry number */
"DSPIRAM", /* NAME : Name of the memory region */
0x11800000, /* ADDRPHYS : Physical address */
0x11800000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0x10000, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
},
{
5, /* ENTRY : Entry number */
"DSPL1DRAM", /* NAME : Name of the memory region */
0x11F04000, /* ADDRPHYS : Physical address */
0x11F04000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0xC000, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
}
} ;
I have followed the following tutorial on davinci wiki to change the memory map.
http://tiexpressdsp.com/wiki/index.php?title=Changing_DSPLink_Memory_Map
My new configuration is:
{
{
0, /* ENTRY : Entry number */
"DSPLINKMEM", /* NAME : Name of the memory region */
0x8FB00000, /* ADDRPHYS : Physical address */
0x8FB00000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0x5000, /* SIZE : Size of the memory region */
TRUE /* SHARED : Shared access memory? */
},
{
1, /* ENTRY : Entry number */
"DSPLINKMEM1", /* NAME : Name of the memory region */
0x8FB05000, /* ADDRPHYS : Physical address */
0x8FB05000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0xFB000, /* SIZE : Size of the memory region */
TRUE /* SHARED : Shared access memory? */
},
{
2, /* ENTRY : Entry number */
"RESETCTRL", /* NAME : Name of the memory region */
0x8FC00000, /* ADDRPHYS : Physical address */
0x8FC00000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0x00000080, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
},
{
3, /* ENTRY : Entry number */
"DDR2", /* NAME : Name of the memory region */
0x8FC00080, /* ADDRPHYS : Physical address */
0x8FC00080, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0x3FFF80, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
},
{
4, /* ENTRY : Entry number */
"DSPIRAM", /* NAME : Name of the memory region */
0x11800000, /* ADDRPHYS : Physical address */
0x11800000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0x10000, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
},
{
5, /* ENTRY : Entry number */
"DSPL1DRAM", /* NAME : Name of the memory region */
0x11F04000, /* ADDRPHYS : Physical address */
0x11F04000, /* ADDRDSPVIRT : DSP virtual address */
(Uint32) -1, /* ADDRGPPVIRT : GPP virtual address (if
known) */
0xC000, /* SIZE : Size of the memory region */
FALSE /* SHARED : Shared access memory? */
}
} ;
I have changed DDR2 size from 1 to 4 MB and moved everything up for 3MB so I
can re size the DDR2. I have not changed the amount of memory that Linux is
allocation (mem=114MB).
Old configuration:
DSPLINKMEM:
start from 254MB
size 1MB
DDR2:
start from 255MB
size 1MB
New Configuration:
DSPLINKMEM
start from 251MB
size 1MB
DDR2
start from 252MB
size 4MB
I have made the same changes on the DSP side. What i don't know is do I need to
change
prog.module("GBL").C64PLUSMAR128to159 = 0x0000FFF0 ;
and to which value?
Any suggerstion?
Tnx,
Benjamin
