Status: SMC91C111 Ethernet Driver Development

[Ian Caddy]

Hi All,

Well, I now have the SMC91C111 driver up and running in my BSP.  We are
currently running release 4.5.0 of RTEMS.

Currently the driver does not use DMA, the driver copies the packet
information into or out of the SMCs buffers.  This will be the next
step.

With the driver in this state, I performed some ttcp testing and found
that I get about 350KBytes/sec performance, but remember there is no DMA
and we are not currently running cache on the 5307 that is running at
64MHz.

There were some overruns while performing the test (the Coldfire was the
receiver) which I expect to get fixed once I get the DMA in place.  This
seems to really slow down the TCP stream.

Also, I want to start moving the driver (or most of it) into the libchip
area.

There may be a slight delay in this as I have to go to the US early next
week for a couple of weeks.

Just another note: I got the webserver application in the netdemos stuff
working, as this impresses the marketing types...:-), but there was a
problem with the make file (had a space on a line that shouldn't have
had one) and the init.c did not initialise the hostname so the webserver
would not startup.

Talk to you all soon,

Ian Caddy
