A2osX Ethernet Driver

[burniouf]

Where could i find documentation to add an ETH driver to support this board ?

https://github.com/A2osX/A2osX

actually supporting, U1, U2, LANCEGS, SSC/PPP...

Support for ethernet on this board has already been implement on IP65. It is based on plugging a W5500 Wiznet module into the board via SPI into the ATMEGA328P. A picture of the board with the ethernet module attached:

https://github.com/profdc9/Apple2Card/blob/main/pics/picver11-with-ethernet.jpg

This is a commonly available W5500 ethernet module. The IP65 version patched to use the Dan ][ controller with W5500 attached is here:

https://github.com/profdc9/ip65

The file that shows how to communicate with the ATMEGA328P to exchange packets is this one:

https://github.com/profdc9/ip65/blob/main/drivers/dan2d.s

It is pretty simple, as most of the logic to actually control the W5500 is implemented by the ATMEGA328P. You can ignore the stuff for "ATARI" as it doesn't really apply here.

A command is sending bytes to the 82C55 port A (wrbt) and receiving them (rdbt).

Initialize:
Send $AC,$10,$XX,$XX,$XX,$XX,$XX,$XX (six bytes of MAC addr to initialize W5500)
receive $00 as confirmation

Poll: (read packet)
Send $AC,$11,packet buf size low byte,packet buf size high byte
Receive two bytes which is length of packet. If $00 $00, no packet is available.
Otherwise is low byte, high byte of length of packet
Then receive that number of bytes as the packet

Send:(transmit packet)
Send $AC,$12,packet size low byte,packet size high byte
Send exact number of packet bytes
Read one byte of result, zero if no error

Hopefully that will get you started.

Ok, Perfect! i can quickly write something...
as i have no HW yet to test, could you send me one of your team able to test at :

https://join.slack.com/t/a2osx/shared_invite/zt-ens62cl0-xeAFLjlRfUSMtzdc6o~Xew

is Dan2eth.drv a proper name for this driver ?

[profdc9]

Dan2eth.drv is just fine as a name for the driver.

I don't have any spare cards right now, but I could build one up. I am quite busy right now so it might be a little while. You could get them faster because there is someone selling them on ebay out of Ireland: https://www.ebay.com/itm/125663287867 You will also need a W5500 card, this one (available from many vendors): https://www.ebay.com/itm/311590216566 And a 10 pin IDC (2 rows X 5) 2.54 mm pitch cable to connect the two.

Ok, thanks... maybe i will order from that guy....

i m almost done writing the DRV.

Any "CLOSE" or "SHUTDOWN" command ?
Any way to get Link Status and 10/100 or HD/FD ?

if someone can test, i will probably get it done today or tomorrow....

[burniouf]

I would also need a way to detect if WIZ is plugged in....or not....for auto-detection routine.

[profdc9]

When the initialization occurs, if you do not get a $00, there is an error initializing. I don't at present have any close or shutdown commands or link status, I only implemented what is needed for IP65. I could look into adding these if it is necessary for A2osX.

it is not mandatory, but other drivers are written like this :

DRV done....

meet me at SLACK if you want a TEST media

Guys, any chance i get a test report about code submitted to Daniel Marks at our SLACK place ?

[profdc9]

Sorry, I have been very busy the past few days. I was working on getting the AosX you sent me working. Unfortunately I can not use the 800k image you send as I do not have a drive emulator. It would be easier if you could send me a zipped 32 MB image file with the driver to test on it. Also, having nothing to do with your code, I need to get my wireless gateway to work in my new location so I can test the ethernet, which I haven't been able to do yet. It just won't connect to by router, I need to figure this out.

ZIP file & instructions to use it posted at SLACK. enjoy.

[profdc9]

By the way, how does AosX figure out which slot the Dan ][ card is in? Does it look for a signature of the ROM? Dan
