Svethlana vs Ethernat driver difference

Postby mikro » Mon Jan 20, 2014 9:11 pm

I'm curious -- are these drivers the same? I'm asking because there have been some changes made to ethernat.xif in the FreeMiNT source tree ('ported' there by me years ago) and there's no source code to svethan.xif available so it's not clear whether the svethlana driver can benefit from those changes or not.

No, the svethlana is implemented in the FPGA, so it's proprietary as far as I know. The ethernat uses the 91C111 ethernet chip.

The ethernat driver was used as a starting point for the Svethlana driver. Its MAC resides in the SV FPGA, and is quite different from the 91C111. Accessing the registers of the Svethlana MAC is a lot easier than the 91C111 so the svethlana source code should be easier to read. We have the source code somewhere here and it really should be part of the official FreeMint source tree. Keep forgetting to send it in though... :roll:
