Hello all! I have some problem with TCP NET Suit. I using LPC2367+Micrel KSZ8721 + TCP/IP Network Suit from Keil. When i set CCLK <= 32Mhz everything is fine. But when i try to set CCLK >32 Mhz there is even no ping my device. But timer_tick () and main_TcpNet() is executing(i see this via my ULINK2 Debugger).
Maybe i have to reduce RMII frequency or something else. Please help.
Thanks for all. I solved this problem. There is no problem with TCP/IP Network Suit. It's necessary to reduce frequency on MDC output by setting in MAC_MCFG register host clock dividers.
With best regards, Vladimir.
