AM2634: MCSPI discard all MCSPI frames received

Part Number: AM2634

Hi experts

May I've found another bug in the current MCSPI driver (mcu_plus_sdk_am263x_08_06_00_34).

MCSPI_Transaction / API says:

  void                   *rxBuf;
    /**< [IN] void * to a buffer to receive data.
     *
     *   If rxBuf is NULL, the driver discards all MCSPI frames received.
     *
     *   The size of the buffer is similar to txBuf as explained above.
     */

If I use the "mcspi_loopback_dma_am263x-lp_r5fss0-0_freertos_ti-arm-clang" example and change rxBuf to NULL:

    spiTransaction.txBuf    = (void *)gMcspiTxBuffer;
    spiTransaction.rxBuf    = (void *)NULL;

Than the CPU gets stuck when executing the code via CCS / Debug.

Since this feature presumably increases efficiency when only data is sent and not received, I wanted to ask if anyone could take a look at this?

Thanks and best regards
