[En-Nut-Discussion] Ethernut with SPI Ethernet Chip

[Ole Reinhardt]

Hi!

As mentioned in one of my last mails, I just found a board with EN28J60
in my cupboard (http://www.lochraster.org/etherrape/  only german so far...)

Unfortunately the original software is GPL based, and therefor not
compatible with Nut/OS BSD license model. But however I have some
different sources, which I will try to use as a starting base for a driver.

The way to go would be:

Create a new spi-bus client driver and add the SPI node struct as ICB to
the ETH device struct.

The SPI MMC driver is a good example how to integrate the SPI node with
a "normal" device.

The device can the be registered with NutRegisterSpiDevice() instead of
NutRegisterDevice().

Best regards,

Ole
