Simon, your right. Indeed, the MAC that should take care of it.
I checked: although the MAC was correctly set up in half-duplex mode, too,
but the low level driver did not take care of any error bits generated by
the MAC during collisions.
Anyway, now works correctly in full-duplex mode.
Jason, my project is nothing special, a home server running on Arch Max v1.1
board, based on the Arduino_STM32 core
<https://github.com/stevstrong/Arduino_STM32> .
I am now struggling with HTTP SSI and CGI stuff, but this is subject of
another topic.
