- initial prototype, based on Plipbox framework
- handles some oddities with the current CPLD by software
workarounds, i.e. needs future changes to go along
with updated JED
- lots of TODO still pending

Installation:
|
|
-------------
|
|
|
|
The driver (enc624j6net.device) needs to be copied into Devs:Networks. The configuration
|
|
depends on the TCP/IP stack of choice. Please refer to the respective documentation
|
|
how to configure a network interface.
|
|
|
|
Use the supplied GUI for stacks like Genesis or Miami and add a regular ethernet card
|
|
within those by referring to the enc624j6net.device, unit 0.
|
|
|
|
The recent RoadShow stack is commandline-based. Please add a new file in devs:NetInterfaces,
|
|
such as a copy of the PlipBox interface specification with the device entry replaced by
|
|
enc624j6net.device. The command AddNetInterface with the filename of your interface spec
|
|
as argument will then activate the driver for RoadShow.

Technical notes:
|
|
----------------
|
|
|
|
Matze's card does selective byte swapping for different areas of the chip within
|
|
the CPLD. This step enables Big Endian reads/writes to the hardware registers. Since
|
|
the SRAM would be byte-swapped as well, the latest (WIP) version of the CPLD presents
|
|
TX and RX frames in Big Endian (network order) as well. As a consequence, the
|
|
low-level part of the driver won't work out of the box with with other approaches
|
|
towards 16 Bit parallel connections of the ENC624J600 chip.

My deepest respects go to Christian Vogelgsang (lafalla) for his plipbox project.
|
|
His invaluable work on further cleanups and abstractions to the already well written
|
|
magPLIP made a quick swap of low-level functions quite easily possible.
|
|
|
|
The ENC624J6 source is heavily based on plipbox, which is in turn based on the magPLIP
|
|
driver found on aminet.net:

Changes have been made by Stéphane Zermatten to the driver to connect
|
|
a LinuxBox to an Amiga via a LapLing cable, based on the release 37.8.
