Hi, Our design uses an LPC2468 with DP83848 PHY. We lose some Ethernet frames transmitted by our firmware. When I say that we lose the frames, they have been transmitted as far as we can tell from the MAC registers in the LPC, but they are not detected by the PC at the other end of the wire (running a Wireshark capture). The test setup was an isolated point-to-point link with a s...
