Query about Ethernet(Emac Controller)

ghanshyam gajjar

Dear Sir,

We are using LPC2364 Arm Controller for our application project.In our project main different block are 20 * 4 LCD display, USB, Ethernet, SPI, UART. We have designed two different broad. In one broad contain main controller LPC2364,SPI,UART. And other board contain USB & Ethernet driver IC. We have developed a code( USB ,Ethernet,SPI,UART drivers) which is working properly when both board are connected. But with a same code if we removed USB, Ethernet board & and give power to main controller (LPC2364), controller get hang.

We have found problem by debugging that problem is in INITILIZATION of EMAC controller block. Is it required to connect driver IC while Initilization of Emac block or enable the ethernet clockDear Sir,
