RTOS/AWR1642BOOST: SPI slave transaction aborts execution

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642, SYSBIOS

Tool/software: TI-RTOS

I'm trying to implement SPI communication on the Traffic Monitoring lab. I achieved successful communication with Master mode, but when I configure Slave mode and I run SPI_transfer(), I get the following command lines:

{module#8}: "../dss_main.c", line 212: error {id:0x10000, args:[0x814364, 0x814364]}
[Cortex_R4_0] xdc.runtime.Main: "platform/mmwave_xwr16xx.c", line 1342: assertion failure
xdc.runtime.Error.raise: terminating execution

My configuration code for the SPI driver is:

SPI_Params_init(&params);

    params.mode = SPI_SLAVE;
    params.frameFormat = SPI_POL0_PHA0;
    params.pinMode = SPI_PINMODE_4PIN_CS;
    params.shiftFormat = SPI_MSB_FIRST;
    params.dmaEnable = 1;
    params.dmaHandle = dmaHandle;
    params.u.slaveParams.dmaCfg.txDmaChanNum =1U;
    params.u.slaveParams.dmaCfg.rxDmaChanNum =0U;
    params.transferMode = SPI_MODE_BLOCKING;
    params.dataSize = 8U;
    params.u.slaveParams.chipSelect=0;

My code to call the transaction function is:

     uint16_t a = 2;
        char r;
        SPI_Transaction spiTransaction;
        spiTransaction.count = sizeof(uint16_t);   //COUNT= number of frames for this transaction
        spiTransaction.txBuf = (void *)&a;   //void * to a buffer with data to be transmitted
        spiTransaction.rxBuf = NULL;        //receive
        spiTransaction.slaveIndex=0;

        int ret = SPI_transfer(SPIhandle, &spiTransaction); //llamo a la funcion
        if (!ret) {
            System_printf("Unsuccessful SPI transfer");
        }

I've already checked the SPI test files in the driver folder and got no information for this problem. Could you help me solving it?

Debugging, I've noticed that it crashes when it reaches

MIBSPI_dataTransfer(ptrMibSpiDriver, transaction->txBuf, transaction->rxBuf, dataLength, transaction->slaveIndex);

line 2267 on mibspi_dma.c

it seems that it gets stuck in a semaphore_pend function.

I also forgot to mention I'm using sdk v2.00.00.04

Hello Carlos,
Have you tried running SPI driver test application (SPI-slave) where it has PC based SPI-master application to read data from AWR1642 (SPI-slave)
C:\ti\mmwave_sdk_02_00_00_04\packages\ti\drivers\spi\test\xwr16xx
Try to run this application first to verify SPI-slave on the device is working fine.

The ASSERT what you have mentioned on top is occurring at the mmWave library while writing data over mailbox to DSS/MSS core, you need to check that point.

Regards,
Jitendra

I haven't. Right now I can't test it but as soon as I go back from holiday I will do it.

How do you suggest running the test code? should I copy the Test_spiSlaveWithPC to my code and see what happens? Or do I need to compile the test code into the device?

Try to run individual SPI test appliaction where it provides PC based application to complete master-slave communication. This is to get the understanding of code flow and then try to move specific/required code from there to your application.

I'll try as soon as possible and I'll come back here to post the results. thanks

hi, I ran the test application and I'm getting the following console feed:

[Cortex_R4_0] ******************************************

any ideas?

I'm guessing that it is aborting when the SPI_transfer function gets called, as it did in my code.

I'm sorry I pressed the "this resolved my issue" button, it didn't...

also, I tried to run the sdk v3.00.08 test with the same exact result, and I was able to run the uart driver test with no problems

EDIT: I've been able to finally run the test code with no problems. I think the issue was not having the DSP core connected. I've copied the Test code into my code, and when I run it, I get the following console feed:

[Cortex_R4_0] Debug: SPI Instance @0801c84c has been reopened in MASTER mode successfully
[C674X_0] {module#8}: "../dss_main.c", line 212: error {id:0x10000, args:[0x814364, 0x814364]}
[Cortex_R4_0] Start SPI Write test with MSP43x
Master write Throughput = f Mbps
xdc.runtime.Main: "platform/mmwave_xwr16xx.c", line 1342: assertion failure
xdc.runtime.Error.raise: terminating execution

And then it aborts again. I've noticed that the [C674X_0]... line and xdc.runtime.Main: ... are the same errors that I had before.

EDIT2: until now i've been running the spi code from the mboxread task. I've tried to move the code to main but still it crashes

Hi Carlos,

I apologize for the delayed response - we did not see the replies after the thread was marked resolved.

Could you please let us know if this is still an issue for you?

Best Regards,
Anand
