RTL8019as - Specific info needed.

Hello All,

  Some time ago (years actually) I encountered an article named the '25$
webserver'.  It was about connecting a microcontroller to an NE2000
compatible ISA network card.

Just recently I thought it would be a nice project to connect a RTL8019as
NIC to an Atmel Mega32 microcontroller and using assembly as the
language-of-choice.   A further googling found me a site using BasCom, from
which I learned how to initialize as well as how to read from & write to the
NIC.

But all of the PDF documentation in regard to that NIC seemed to be
incomplete, and the only way I could download some (supposedly!) more
specific information from the company itself was to agree to a NDA
(non-disclosure agreement), which I, as a hobbyist, did not wish to do.

My question is therefore : does anyone know of where to get specific info in
regard to that NIC *without* having to sell my soul ?

Regards,
  Rudy Wieser

Google is your friend..

www.kamami.pl/dl/rtl8019as.pdf

That's the complete datasheet.

You should also check out Linux kernel driver for this chip:

Hello Jim,

   Thanks for your link.   Unfortunatily that was exactly the same as other
documents I found.

Maybe I should have been more specific in my earlier message.   What I could
not find is a description of what the first two (the second two is the
byte-count) and the last four bytes mean when I read a full block of data
(the eight bytes wrapping the ethernet-packet).  Have I overlooked that info
in the document somehow ?

As I could not find that info (nor any example of what needed to be done to
initialize the NIC or read from/write to it) and because of that NDA
agreement I assumed that the document I found and you also provided is
incomplete.  Maybe the (non-existant?) 'full' document would divulge some
more secrets (like why the code I found seems to check bit #6 of the last
byte of a read packet and clear the ISR if its set).

If all else fails I'm going to disassemble the PNPPD.COM device-driver for
under DOS that came with it and see what I can learn from it, but would
rather not have to do that ...

  Rudy Wieser

Hello przemek klosowski,

  Thanks for the link.  I just took a look at it and do not think I can use
it : I would be wrestling with understanding that code as well as bumping
into the differences between that 8139 and the 8019 chip.  I'm afraid that
it would be just too confusing.

Regards,
  Rudy Wieser

P.s.
A quick search in that depository for the 8019 revealed that there was none
to be had.

First of all, go here...

http://www.crynwr.com/

And download the packet driver spec and the
generic NE2000 packet driver.

Then go to my website and download...

http://www.jkmicro.com/downloads/zip/picopkt.zip

That's the NE2000 driver modified for the
RTL8019as running in 8-bit mode.  Be aware that
we use a programmed eeprom to set the mac address
and the initial I/O port, interrupt and bus
width.

All is in x86 assembly, but hey, it's free.

And if you do get something to work, let us
know and put it up somewhere that we can use
it.

best,

Hello Jim,

  Thank you for that PicoPkt.zip.  It turned out that I allready had the
packet-driver spec (for quite some years even.  I did some DOS ethernet
stuff).   But as for that "generic NE2000 driver" ?   The closest I could
find on that site is a NE2100.ZIP file, which I don't think is what you
mean.

Do you maybe mean that I should google me a packet-driver ?   If that is so
I allready got a packet-driver program (on floppy) together with the
RTL8019as ethernet-card, a file named PNPPD.COM (the DOS packet-driver).   I
allready was disasembling it for info before I thought of trying to go the
"easy way" and ask this community. :-)

Currently I got ARP, ICMP (ping), IP and UDP (echo) to work.   TCP will take
me a bit more, as I'm not yet sure how I should handle multiple requests.

All I have now is code that will work in optimum conditions (a single
computer connected to the card/microcontroller).  I'm not sure how it will
behave in a bit more hostile environment (multiple computers talking to each
other, multiple incoming TCP/IP requests).   The code I used as a launch-pad
(pretty-much copied the initialisation and the block read/write routines)
shows code that I have no idea what it does.  When I left it out all
continued to work.  But I can't say I like not knowing what it does, it may
be quite important ...

  Rudy Wieser
