[En-Nut-Discussion] RTL8019AS is not running

[Harald Kipp]

The RTL8019AS is highly sensitive to ESD. Almost all fatal failures with 
Ethernut 1 boards are caused by damaged Realteks. However, typically 
Basemon still correctly detects the chip and reading or writing the NIC 
registers works fine. It simply fails to set up the Ethernet link or to 
send or receive Ethernet frames.

Did Basemon detect all external RAM? If yes, then most probably the 
RTL8019 is the problem. If not, than the ATmega or the 74(A)HC573 may 
broken. The latter is most unlikely, though.
