Trying to generate the lwip design in SDK

I have an Artix design and I am trying to create the LWIP example design using the new application project in SDK. I am getting some errors which I have traced using the log as not enough memory (see below). I have DDR2 on the FPGA so firstly is it not possible for it to just run out of that? Or how do I find out how much memory I need (I have 32k at the moment).

Thanks

Hi Sam

 

Yes I would do that, but it wont even let me create a new app unless there is enough BRAM. So it seems to use that by default without giving any other option. Unless I am doing something wrong it seem a bit stupid.

So I increased the BRAM to 64k and I still get the error. Can nobody from Xilinx tell me what is going on? Just how much memory does this thing need? I can't believe that 64k inst enough.

you can place all the sections in DDR. The application for lwip would be quite large (~1M)
