Hi, i need to set up a TCP/IP or UDP network and config my board (lpc1768) as a client with a KS8721 PHY IC! i changed "PHY Identifier" to a ks8721 id and set "PHY device address" with my board parameters (PHY Add. pins), setting Full-Duplex and 100Mb/s speed manually:
write_PHY(PHY_REG_BMCR,0x2100); // Full Duplex - 100Mb/s
and at last comment the link status checking code because KS8721 doesn't have the PHY Status Register like dp83848 has! Finally i could test LEDClient file (Keil\MCB1700\RL\TCPnet\LEDClient), UDP network connected and data sent to PC (sniffer it with Hercules_3.2.8 sw) from micro. BUT when i sent anything from pc to micro, udp_callback doesn't called!!! is there anything i should do more? or anyone who used TCPnet with KS8721?
tnx all
Hello Mostafa,
I think you will need to do a bit more than only changing the identifier and device address of the PHY. Please compare the technical reference manuals of the two PHYs against each other and try to find out, what you need to do to initialize the KS8721. Unfortunately, this is not trivial.
Kind regards,
Christopher
