hi,
Iam using only external 50MHz crystal at pin(72),Iam using RMII mode ,but the same crystal is used in the k60 the Ethernet is worked fine but for k66 Ethernet is not working , I made MCG_c2 registers EREFS bit to logic 1, even thought it not working . Iam using the code warrior generated code for the k60 , now only change I replace the k60 with k66, I don't know how to enable the interrupts in the code warrior generated code because irq numbers gets changed in k66 , I possible can you send Ethernet application in keil 5 for k66 ,
