I made a DM648 board myself copied from Lyrtech's EVM. In network part, I am debugging using NDK 2.0 in DM648 side. But it seems that Mac(DM648) has no communication with two PHYs(88E1111, Marvell).
The phenomena are that:
when I send message from PC, the RX LED in RJ45 will flash, but Mac will not response, i.e. pinging from PC is not successful;
when I try to send raw data using NDK 2.0 from mac, CCS shows that data have been sent out, but in RJ45's TX LED never flash. And my PC receives no packet( using Ethereal to detect).
I am wondering whether there are some parameters I should regulate in NDK, or the configuration of PHY should be changed according to Lyrtech's previous version.
Thanks for your reply!!
