Re: [ECOS] Multi-cast mode warning

[rholmberg <randy dot holmberg at liposonix dot com>]

Tim,
Can you please tell me if you were able to get the DP83848 to function
properly with the AT91RM9200? I have an application that is planning to use
the same DP83848CW Ethernety PHY with the AT91RM9200 - it would be very
reassurring to know that someone has successfully implemented these items.


Best Regards,

Randy Holmberg
