    Hi,

    This is the 8K EMAC Controle Module RAM:
    0x01E2 0000 - 0x01E21FFF

    Hi,

    Thanks for the CPPI RAM address. I would also like to know something about TX0PEND bit. Will the TX0PEND bit will automatically get cleared after the CPU transmits the packets . I am sending two ethernet packets from my DSP(custom board). I can see the packets getting transmitted from EMAC module(TXGOODFRAMES = 2, which are multicasted). Then the TX0PEND interrupt is raised . I have multiplexed the EMAC interrupts to DSP interrupts. When TX0PEND interrupt is raised the EVTFLAG corresponding to TXC0(transmit channel zero) is raised but the IFR corresponding to the event flag is not raised(as the default value of EVTMASK is 0 the events are combined automatically and I also multiplexed the event to one of the 12 dsp interrupts). I tried to check if i'm getting any data on data lines(TXD0 AND TXD1, RMII mode) using picoscope but nothing is seen on them. I have enabled TXEN . I tried to capture ethernet packets on Wireshark(v2.6) but there also I can't find my packets. Am I missing something. Please help me with this.

    Thanks and Regards,
    Vishnu
