Hi, everyone.
I'm doing a work with BeagleBoard which use its DSP, the way of communication is DSPLINK, but I'm having many problems.
I'm trying run the G.729 codec in the DSP, my application is based in demo sample readwrite that come with DSPLINK.
The main fuction in GPP side is it:
NORMAL_API
DSP_STATUS
TP_Execute (IN Uint32 dspAddress,
IN Uint32 bufferSize,
IN Uint32 numIterations,
IN Uint8 processorId,
IN Char8 * bufferPCM,
IN Uint32 sizeBufferPCM,
IN Char8 * bufferG729,
IN Uint32 sizeBufferG729
)

Uint16 * bufIn = NULL ;
Uint16 * bufOut = NULL ;
Uint8 * ptr8 = NULL ;
Uint8 * ptr8_1 = NULL ;
Uint16 * ptr16 = NULL ;
Uint16 * ptr16_1 = NULL ;
Uint32 dspAddr1 = dspAddress ;
Uint32 dspAddr2 = (dspAddress + bufferSize) ;
//Uint32 dspAddr2 = (dspAddress + bufferSize) ;
SampleMessage * msg ;
Uint32 i, j ;
status = TP_AllocateBuffer (bufferSize, (Pvoid *) &bufIn) ;
if (DSP_FAILED (status)) {
TP_1Print ("BufferIn Allocation Failed. Status: [0x%x]\n", status) ;
}
status = TP_AllocateBuffer (bufferSize, (Pvoid *) &bufOut) ;
if (DSP_FAILED (status)) {
TP_1Print ("BufferOut Allocation Failed. Status: [0x%x]\n", status) ;
}
memcpy(bufIn, bufferPCM, bufferSize);
/* Write the data buffer to the DSP side */
if (DSP_SUCCEEDED (status))
{
status = PROC_write (processorId, dspAddr2, bufferSize , bufIn) ;
if (DSP_FAILED (status))
{
TP_1Print ("1 - PROC_write Failed. /Statu : [0x%x]\n", status) ;
}
}
/* Prime the data buffer for the sample application
* - Initialize the buffer to '1's. This value is multiplied

*/

---------//---------//-------------//--------//-------
the main code of DSP side is it:

*/
status = MSGQ_get (info->dspMsgqQueue, (MSGQ_Msg *) &msg, SYS_FOREVER) ;
if (status == SYS_OK)
{
writeBuf = (Uint16 *) msg->gppWriteAddr ;
readBuf = (Uint16 *) msg->dspWriteAddr ;

new_speech = &readBuf[160];
HAL_cacheInv ((Ptr) readBuf, size) ;
Init_Pre_Process();
Init_Coder_ld8a(readBuf);
Set_zero(writeBuf, PRM_SIZE);
// * Loop for each "L_FRAME" speech data. * /
Pre_Process(new_speech, L_FRAME);
Coder_ld8a(temp); //Codigo Principal
for(j =0 ; j < 11; j++)
writeBuf[j] = temp[j];
//prm2bits_ld8k( temp, serial);

status = MSGQ_put (info->gppMsgqQueue, (MSGQ_Msg) msg) ;

SET_FAILURE_REASON(status);

}
return status ;
}
I pass to DSP the below memory address, how do the MMU translate it to physical memory?
strDspAddress = "2280587264"; //transforme to MB - 2280587264/1024/1024 = 2174.9375 MB - what is wrong?
But always I get this erro:
DSP MMU Error Fault! MMU_IRQSTATUS = [0x1]. Virtual DSP addr reference that generated the interrupt = [0xfffffff8].
The code of GPP is inside of a "for" (I want to compact a file of voice, and this code is executed with 80 samples of voice), and this problem is got after some interations. I have read some troubleshooting but don't solve my problem.
I don't change nothin in memory map, I use the same of readwrite example (and the readwrite example works)
and if I want change the memory map in the file CFG_OMAP3530_SHMEM.c I need rebuild the dsplink module?
I'm in this problem have a month and I don't know what's I can do.
Sorry for my bad english
thanks
Willian Henrique
