That's good to hear. Could you please tell us, what went wrong on your

Note, the current nic_drv supports AMD PCnet32 devices only. Those
are emulated in qemu if run like this:

  qemu -net nic,model=pcnet

I think that someone successfully used e1000 drivers with dde_linux26.
So, other drivers may also work with some effort. test-dde_linux26_net
is just a test program for uIP and the NIC driver. Please run only
nic_drv if your working with lwIP. Also, a log of the serial output
will help us to reconstruct what happens.

I would expect that 512K will not suffice to run nic_drv. So, please
try 4M or so.
