I am using IAR Ewarm 6.6 example WebServer using LwIP 1.32. The code compiles and loads fine. I also receive Ethernet packets fine but I am not able to transmit them.
The ARP and DHCP frames are formed, and handed off to the DMA engine, and it looks like we get the DMA complete too, but the MII pins never pass the frame to the PHY (PHY is TI/National DP83848). And frames never show up on Ethernet.
Any idea/suggestin what might be causing this?
