Problem with SDK and Two Codec DMA on 56585
Does anyone have any experience using DMA for two
codecs with a DSP56858? I can get the first Codec working fine but when I
try to add a second, I cannot get it to work.
Stepping through essidmadrv.c, I notice that the
section of code below does not appear to be executable in the debugger.
This leads me to believe they #ifdefs are defined but they are in bsp.h
below. If I try to redefine BSP_DEVICE_NAME_ESSI_1_RX_DMA in
appconfig.h, the compiler complains of multiple definitions.
Any ideas?
----essidmadrv.c-------
#else if
(defined(BSP_DEVICE_NAME_ESSI_1_RX_DMA) || \
defined(BSP_DEVICE_NAME_ESSI_1_TX0_DMA) || \
defined(BSP_DEVICE_NAME_ESSI_1_TX1_DMA) || \
defined(BSP_DEVICE_NAME_ESSI_1_TX2_DMA))
if (pHandle->EssiAddress
== &ArchIO.ESSI1)
{
if
(essidma1Created == true)
{
return
(UWord16) 0;
}
essidma1Created = true;
}
else
----bsp.h-----------
#define
BSP_DEVICE_NAME_ESSI_0_TX0_DMA ((const char *)61)
/* ESSI0 TX0 DMA */
#define
BSP_DEVICE_NAME_ESSI_0_TX1_DMA ((const char *)62)
