We are working on Ethernet Driver on TMDSEVM437X board using proprietary RTOS. Driver works well in Interrupt mode. But it is observed that if Interrupts are disabled and we POLL the DMA RX Descriptor OWNER flag (indicates that packet has been completely received), it takes times (in units of seconds) to be clear. Same is the case for SOP flag to be set. Is this expected behavior? What is the optimal time for these flags to be set/clear in the absence of interrupts.
