Altera TSE driver and example program for lwIP (1.3.2)

Did You copy RGMII initialization file into the project? You can take it from RGMII web server example or RGMII simple socket server example projects. Afaik it's called tse_my_system.c. Just copy it to the project tree and recompile.

Thank you, Socrates, that was exactly what I needed to get it running!!!

Maybe this would be helpful for those who need to know link status.

Petrak,

Hello,

    // start the critical section by disabling IRQs
 const alt_irq_context cpu_sr = alt_irq_disable_all();
    // decrement packet counter
    --tse_info->mRxCount;
    // assign current packet from lwIP packet buffer as the new data
    *data = tse_info->mRxBuffer;
    // assign next packet instead and move forward in buffer
    tse_info->mRxBuffer = (void*)next_packet;
    if (++tse_info->mRxIndex >= TSE_RX_BUFFER)
    {
        tse_info->mRxIndex = UINT32_L(0);
    }
    // stop the critical section by enabling IRQs
 alt_irq_enable_all(cpu_sr);
