Just to clarify, a modification I made was calling the ethif_init function ethernet.c file[1] and passing some parameters (base_addr,mac, dma_ops,ethif_recv_callback). Currently, dma_ops and ethif_recv_callback contain null values and I'm not too sure what I need to initialise them as.
Secondly, as I still was not getting a different message in the terminal to suggest an error, I used the same method used for the pc99 boards for initialising the ethernet device. I called the ethif_odroid_init_module function which is the function that the preprocessor symbol is pointing to. Doing so I was able at least try and see if I had done the modification of the code correctly which leads me back to the first point as an assertion error occurred for dma_ops and I presume would happen to ethif_recv_callback as well. Also, please could you clarify how I am meant to modify the callbacks so that it gets the correct registers and IRQs from the DTS.
