[En-Nut-Discussion] Defective Ethernut 1.3 Board

[Michael Hellwig]

Hi ethernut users,

with a wrong wired addon-board, which I did not check thoroughly enough,
I damaged one of our ethernut 1.3 Boards (12V on Port B at least).
Basemon showed a stuck PIN 7 on Port B and the NIC didn't response to pings.
After replaceing the ATMega128 and setting some fusebits
the board works fine again - except the NIC still doesn't work.

I downloaded the testrtl10.zip from ethernut.de.
Since I wasn't able to compile the code myself with NutOS 4.2.1/avr-gcc 
3.4.3 under Linux, I had to patch in an valid IP-Adress and could then 
finally flash the hex-file.

Now I get the following result by executing testrtl:

So two questions:
Can anyone tell from the dump what's wrong here, and if the RTL8019AS is 
defecive, has anybody a few of it for sale?
I dumped all the ISA-NICs with that chip long ago.

P.S. When will somebody publish "The (AVR) NutOS cookbook"?
