FreeRTOS send ethernet frames

Kernel

Have you already checked this testing project for UltraScale?

I think you need to make three steps, one after the other:

  1. Get FreeRTOS running properly
  2. Get FreeRTOS+TCP running properly, try to get ping work.
  3. Start sending and receiving raw packets

Step-3 will be the easiest one.

Do you know if there is something particular that I need
to take care of when dealing with interrupts in FreeRTOS?

Can you make sure that the interrupts are installed?

The general EMAC interrupt handler is XEmacPs_IntrHandler(). It will be called for reception and transmission. It is installed as:

XScuGic_Connect( &xInterruptController,
                 xtopologyp->scugic_emac_intr,
                 XEmacPs_IntrHandler,
                 emac );

The function XEmacPs_SetHandler() sets the three handlers: DMASEND, DMARECV, and ERROR. It is called from setup_isr().
