    Aupers,

    Can you please provide details of the patch that you are referring to. there is no reference to a software patch in the errata so I would appreciate if you can point us to the patch so we can suggest appropriate work around in RTOS.

    Regards,

    Rahul

    Aupers,

    I believe that that this errata has already been dealt with using hwFifoEventDMARatio in the Mcasp_ChanParams_s as configured in mcasp_cfg.c file in the examples. This is a application level configuration that you can tune based on your application requirement. If the user sets this parameter to TX_FIFO_EVENT_DMA_RATIO and RX_FIFO_EVENT_DMA_RATIO as specified in mcasp_tune.h file (refer to the comment in the file)

    mcasp_cfg.c : pdk_am57xx_1_0_10\packages\ti\drv\mcasp\example\evmAM572x\src
    mcasp_tune.h location :pdk_am57xx_1_0_10\packages\ti\drv\mcasp\example\include

    Regards,
    Rahul
