Can you set DEBUG_EEPRO100 in the source file, rebuild and let us know
what extra debug output you get?  Just change the #if 0 around the
define near the top of the file to #if 1.

Alex

Thx you Alex
Here is what i have with DEBUG_EEPRO100 set in the eepro100.c source file

its not crystal clear for me, do you have any clue to get this working a bit better ?
thank you for your advices

Seb

The current emulation only supports 32 bit writes to the "port" address.

I'll read the documentation to see how 16 bit writes should be handled
(obviously your image always writes lower and upper half of the 32 bit
value, and for this case, the solution might be simple).

Is prologue.img available online (so I can run your test scenario)?

Stefan W.
