using interrupt ethernet IRQ

VIVEK Gopalakrishnan

HI,

I want to use interrupt ethernet_IRQ provided by keil. In the routine, memory was allocated, where is it being
freed?

How do I access the received ethernet data? Is the data which is "put in queue" in the FIFO or RAM?

Pls help.

Thanks
vivek

    Thanks Tamir.

    But when i put a break point next to the place where the code allocates memory, i could observe that the pointer was NULL. Also the alloc_mem is called for each frame.

    My question is, Is freeing taken care already or should i free it myself. If alloc_mem calls "realloc" instead, then i think i would have sufficient memory in my heap.

    Thats why i get the feel that i should free it. I couldnt find this in the code documentation.

    How do i access the data after it has been put in the queue in case memory is freed already?

    Thanks for your prompt reply
