Hi All
I used C5502 and want to make McBSP works in Slave mode and My codec is master.I
program my codec from microcontroller and I can check read and write to McBSP1
with this command:
while(1)
{
while (!MCBSP_rrdy(h1));
A=MCBSP_read32(h1);
MCBSP_write32(h1, A);
while (!MCBSP_xrdy(h1));
}
Now my McBSP1 worked.
but when I start DMA I have any Tx or Rx interrupt.
I configured my McBSP1 and DMA channels like this:
MCBSP_configArgs(h1,
0x4000, /* Serial Port Control Register 1 */
0x0000, /* Serial Port Control Register 2 */
0x00a0, /* Receive Control Register 1 */
0x80a4, /* Receive Control Register 2 */
0x00a0, /* Transmit Control Register 1 */
0x80a4, /* Transmit Control Register 2 */
0x0000,//2e38,/*0x2e1c,*/ /* Sample Rate Generator Register 1 */
0xa000,//A02f, /* Sample Rate Generator Register 2 */ // it was
302f
0x0000, /* Multichannel Control Register 1 */
0x0000, /* Multichannel Control Register 2 */
0x0080, /* Pin Control Register */ // it was 0x0e0f
0x0000, /* Receive Channel Enable Register Partition A */
0x0000, /* Receive Channel Enable Register Partition B */
0x0000, /* Receive Channel Enable Register Partition C */
0x0000, /* Receive Channel Enable Register Partition D */
0x0000, /* Receive Channel Enable Register Partition E */
0x0000, /* Receive Channel Enable Register Partition F */
0x0000, /* Receive Channel Enable Register Partition G */
0x0000, /* Receive Channel Enable Register Partition H */
0x0000, /* Transmit Channel Enable Register Partition A */
0x0000, /* Transmit Channel Enable Register Partition B */
0x0000, /* Transmit Channel Enable Register Partition C */
0x0000, /* Transmit Channel Enable Register Partition D */
0x0000, /* Transmit Channel Enable Register Partition E */
0x0000, /* Transmit Channel Enable Register Partition F */
0x0000, /* Transmit Channel Enable Register Partition G */
0x0000);
DMA_configArgs(hDmaRcv,

);
DMA_configArgs(hDmaXmt,

0x0000); // CDE
Now I hanged and cant do anything.
Has anyone had a similar problem? or can help me to solve this problem?
