AM5718: McASP configuration issue

Shan muhammad

Part Number: AM5718

Hi,

I am using AM5718 ,Iam trying to configure MCASP (1 and 2) in I2S mode by polling status register(without EDMA).I followed your APIs as per SitaraWare_Audio .(https://processors.wiki.ti.com/index.php/SitaraWare_Audio) .

McASPTxReset(SOC_MCASP_CFG_BASE);
McASPTxFmtI2SSet(SOC_MCASP_CFG_BASE, WORD_SIZE, SLOT_SIZE,
MCASP_TX_MODE_DMA);
McASPTxFrameSyncCfg(SOC_MCASP_CFG_BASE, 2, MCASP_TX_FS_WIDTH_WORD,
MCASP_TX_FS_EXT_BEGIN_ON_FALL_EDGE |
MCASP_TX_FS_INTERNAL);
McASPTxClkCfg(SOC_MCASP_CFG_BASE, MCASP_TX_CLK_INTERNAL,((MCASP_ACLKX_CLKXDIV_VALUE &
MCASP_ACLKXCTL_CLKXDIV_MASK) >>
MCASP_ACLKXCTL_CLKXDIV_SHIFT),
((MCASP_AHCLKX_HCLKXDIV_VALUE &
MCASP_AHCLKXCTL_HCLKXDIV_MASK) >>
MCASP_AHCLKXCTL_HCLKXDIV_SHIFT));
McASPTxClkPolaritySet(SOC_MCASP_CFG_BASE, MCASP_TX_CLK_POL_FALL_EDGE);
McASPTxTimeSlotSet(SOC_MCASP_CFG_BASE, I2S_SLOTS);
McASPSerializerTxSet(SOC_MCASP_CFG_BASE, MCASP_XSER_TX_0);
McASPSerializerTxSet(SOC_MCASP_CFG_BASE, MCASP_XSER_TX_1);
McASPPinMcASPSet(SOC_MCASP_CFG_BASE, (MCASP_PIN_AFSR |
MCASP_PIN_ACLKR | MCASP_PIN_AFSX |
MCASP_PIN_AHCLKX |
MCASP_PIN_ACLKX |
MCASP_PIN_AMUTE |
MCASP_PIN_AXR(MCASP_XSER_TX_0) |
MCASP_PIN_AXR(MCASP_XSER_TX_1)));
McASPPinDirOutputSet(SOC_MCASP_CFG_BASE, MCASP_PIN_AFSR);
McASPPinDirOutputSet(SOC_MCASP_CFG_BASE, MCASP_PIN_ACLKR);
McASPPinDirOutputSet(SOC_MCASP_CFG_BASE, MCASP_PIN_AFSX);
McASPPinDirOutputSet(SOC_MCASP_CFG_BASE, MCASP_PIN_AHCLKX);
McASPPinDirOutputSet(SOC_MCASP_CFG_BASE, MCASP_PIN_ACLKX);
McASPPinDirOutputSet(SOC_MCASP_CFG_BASE, MCASP_PIN_AXR(MCASP_XSER_TX_0));
McASPPinDirOutputSet(SOC_MCASP_CFG_BASE, MCASP_PIN_AXR(MCASP_XSER_TX_1));
McASPTxClkStart(SOC_MCASP_CFG_BASE, MCASP_TX_CLK_INTERNAL);
McASPTxClkCheckConfig(SOC_MCASP_CFG_BASE, MCASP_TX_CLKCHCK_DIV32,
0x00, 0xFF);
McASPTxSerActivate(SOC_MCASP_CFG_BASE);
McASPTxEnable(SOC_MCASP_CFG_BASE);
while (McASPTxStatusGet(SOC_MCASP_CFG_BASE) & MCASP_TX_STAT_DATAREADY);
McASPTxBufWrite(SOC_MCASP_CFG_BASE, MCASP_XSER_TX_0,
0xAAAAA000);

I got both clock and frame sync.but code was hanged at the time of checking Tx Status ready and there was no output through serial data lines .

Hi Shan,

Because you used EDMA for TX and you did not set up the EDMA for TX.

McASPTxFmtI2SSet(SOC_MCASP_CFG_BASE, WORD_SIZE, SLOT_SIZE,
MCASP_TX_MODE_DMA);

Hi Ming Wei,

I changed my configuration to non dma mode by changing MCASP_TX_MODE_DMA to MCASP_TX_MODE_NON_DMA. But there was no change at output(No output through data lines) and hanged at the same place.Current MCASP_TXSTAT register is

Hi Shan,

For the transmitting loop, you should have done the following:

while(1)
{

        serailizerXmtStatus = McASPIsSerializerXmtReady(SOC_MCASP_CFG_BASE,MCASP_XSER_TX_0);
        if(serailizerXmtStatus)
        {
            McASPTxBufWrite(SOC_MCASP_CFG_BASE,MCASP_XSER_TX_0, 0xAAAA0000);
        }

}

Hi Ming Wei,

I changed my code as per your suggestion.but no change at output.

serailizerXmtStatus = McASPIsSerializerXmtReady(SOC_MCASP_CFG_BASE,MCASP_XSER_TX_0);

Function McASPIsSerializerXmtReady always returns a zero,So there was no entry to the function 'McASPTxBufWrite'

Hi Shan,

Because you said the program execution passed the following code:

while (McASPTxStatusGet(SOC_MCASP_CFG_BASE) & MCASP_TX_STAT_DATAREADY);

McASPTxBufWrite(SOC_MCASP_CFG_BASE, MCASP_XSER_TX_0, 0xAAAAA000);

You should at least saw one 0xAAAAA000 on the data line. Are you sure you measured on the correct pin for MCASP_XSER_TX_0?

Hi Ming wei,

Yes, i verified all pins once again.I was generated it using pin mux tool.boardPadDelay.h

Because you said the program execution passed the following code:

program execution always hanged at while loop(at the time of status check) that i mentioned in my previous post.

There is a statement in your TRM.

McASP1, McASP2, and McASP3, whose data ports are accessible directly via L3_MAIN do
not support FIFO/constant addressing modes. Incrementing transfers must be used instead.

What does it mean?? Can i able to transfer data through the buffer named 'MCASP_TXBUF' using MCASP1,2,3??

Hi Shan,

It means you can access to the McASP 1/2/3 TX_BUF via MCASP_TXBUFn (n is the number of the serilizer). For example for MCASP1, 0x48460200 for serilizer 0 TX and 0x48460204 for serilizer 1 TX.. If you are using EDMA, you will need to use incremental address mode for more than one serilizers.

Because your MCASP_TXSTAT, XDATA bit is 1, it seems your MCASP is never ready for data transmitting. You may want to check your MCASP configuration. Please compare your code with the example code in C:\ti_am5_610\pdk_am57xx_1_0_16\packages\ti\csl\example\mcasp\mcasp_transmit\mcaspTransmit.c and C:\ti_am5_610\pdk_am57xx_1_0_16\packages\ti\board\diag\mcasp\src\mcasp_poll_test.c. In particular BoardDiag_audioLoopbackTest().

Hi Ming Wei,

I successfully rebuilt McASP using your test code(mcasp_poll_test.c) and it's worked now. Thank you Ming Wei
