    I want to use continous Ethernet-DMA transfer with a ring buffer. But when I set the continous flag (CONT_EN, bit 12) in the RX Control Register (ENET_RXCR, offset 14h) the transfer stops after one received frame. Is there anything more to do to enable the ethernet-dma to copy all received frames consecutively in the ram ?

    Hi,

    Are you using only one Rx DMA descriptor or a set of descriptors?

    Best regards,
