[En-Nut-Discussion] Weird behavour

[Hugo Perez Casanova]

Harald,

Yes they are. In fact there are 15 boards with the same software in the
same switched network, all of them Ethernut-1. Only the ones that I
mentioned misbehave.

With the basemon I noticed a couple of things:

1. MAC address was 00:00:00:00:00:00 when starting the web server. I set
it to Egnite's OUI and the serial number on the board.

2. Sometimes I can read Software Reset at the serial port when entering
the web server.

I can send ethernet broadcasts with the second board using basemon but
nothing else.

The software we use logs thru the serial port the telnet connections
that are done. Once I read that in the board that links but never
answers (does ethernet broadcasts) when trying to connect to it the free
memory message showed something like 40 MB free.

I will contact Egnite. But I would like to know if there is something
like a full-featured self check that the board could run, so I can
figure out what is causing the problem.

I'll check temperature and supply voltage as Alexander suggests anyway.

Regards.
